Professional Drainage and Stormwater Services

Professional drainage and stormwater services help control rainwater, reduce standing water, improve runoff, and protect homes, businesses, landscapes, and outdoor surfaces from moisture-related damage. A well-designed drainage system collects water where it causes problems and directs it toward an appropriate discharge point, storage area, or infiltration system.

Drainage problems can develop when land slopes toward a building, downspouts release water near the foundation, soil drains slowly, paved surfaces concentrate runoff, or an existing drainage system becomes clogged or damaged. Water may collect in lawns, enter basements or crawl spaces, erode soil, damage landscaping, undermine pavement, or create muddy and unusable outdoor areas.

French drain installation, sump pump installation, and yard grading are three of the most frequently requested drainage services. Additional solutions may include catch basins, channel drains, downspout drainage, dry wells, swales, storm drain systems, culverts, erosion control, drainage maintenance, and commercial stormwater management.

French Drain Installation

A French drain is a subsurface drainage system designed to collect water from saturated soil and redirect it away from problem areas. A typical system consists of a sloped trench containing perforated drainage pipe surrounded by clean drainage stone and wrapped or separated with suitable filter fabric.

Water enters through the stone and pipe openings, then flows through the pipe toward an approved outlet. French drains are commonly used to address soggy lawns, hillside seepage, water near foundations, wet crawl spaces, and low areas where subsurface moisture remains after rainfall.

Yard French Drains

A yard French drain can intercept groundwater or collect water within saturated soil before it reaches a lawn, landscape bed, patio, or building. Placement is based on the direction of water movement, property slope, soil conditions, and available discharge options.

A French drain is most effective when it is installed at the correct elevation with consistent slope, suitable pipe, clean aggregate, filtration materials, and an appropriate outlet. A trench filled with gravel but lacking a functional discharge path may hold water rather than solve the underlying problem.

Foundation French Drains

Foundation drainage systems help manage water that collects near basement walls, crawl-space foundations, and slabs. Depending on the building and project, drainage may be installed outside the foundation, inside the basement perimeter, or as part of new construction.

Exterior foundation drainage may involve excavation, waterproofing coordination, drainage board, perforated pipe, stone, filter fabric, and careful backfilling. Interior perimeter systems normally collect water and direct it to a sump pump.

Drainage and waterproofing serve related but different purposes. Drainage controls water movement, while waterproofing helps resist water passing through the structure. Some properties require both approaches.

Interceptor and Curtain Drains

An interceptor or curtain drain is positioned across the path of water moving through a slope or saturated soil. It collects subsurface water before it reaches a building, lawn, retaining wall, or other vulnerable area.

Successful placement requires understanding the direction, depth, and source of the water. A drain installed too shallow, too deep, or parallel to the water’s movement may not intercept the intended flow.

French Drain Repair and Replacement

French drains can lose effectiveness because of sediment buildup, collapsed pipe, inadequate slope, damaged outlets, root intrusion, filter failure, or poor original installation. Repair may involve cleaning accessible components, replacing blocked sections, correcting the slope, rebuilding the outlet, or installing a new system.

Warning signs of French drain problems include:

• Standing water returning after rain
• Water surfacing along the trench
• No flow from the outlet
• Soil or roots inside the pipe
• Collapsed or separated pipe
• Erosion near the discharge point
• Water backing up toward the foundation

Sump Pump Installation

A sump pump removes water that collects in a basin or sump pit, usually at the lowest part of a basement, crawl space, or drainage system. When the water reaches a set level, the pump activates and moves it through a discharge pipe to an approved location away from the building.

Sump pumps can help manage groundwater, foundation drainage, and water collected by interior perimeter drains. They reduce the likelihood of water accumulation but cannot guarantee that flooding will never occur. Pump capacity, drainage design, power availability, maintenance, and discharge conditions all affect performance.

Primary Sump Pump Systems

Primary sump pumps are normally powered by the building’s electrical system. Common designs include submersible pumps installed inside the basin and pedestal pumps with motors positioned above it.

The correct pump should be selected according to expected water volume, required lifting height, discharge-pipe length, pipe size, check-valve requirements, basin dimensions, and the frequency of operation.

Battery Backup Sump Pumps

A battery backup sump pump can provide limited pumping during a power outage or primary pump failure. Backup systems are especially useful because severe storms that increase groundwater can also interrupt electrical service.

Battery condition, charger operation, pump capacity, alarm function, discharge layout, and expected runtime should be checked regularly. A backup pump does not eliminate the need to maintain or replace the primary system.

Water-Powered Backup Pumps

Some properties may be suitable for water-powered backup pumps. These systems use pressurized municipal water to create pumping action and do not depend on batteries. Availability and suitability depend on water service, pressure, plumbing requirements, water-use considerations, and applicable regulations.

Sump Pump Replacement

A sump pump may need replacement if it no longer activates reliably, runs without moving water, cycles excessively, makes unusual noises, overheats, or cannot handle the incoming volume. Pump age, corrosion, motor condition, switch operation, basin condition, and discharge restrictions should be evaluated.

Sump Pump Repair

Some sump pump problems involve the float switch, check valve, power supply, clogged intake, frozen discharge, loose connections, or debris in the basin. Repair begins with identifying whether the failure is in the pump, controls, piping, electrical supply, or drainage system feeding the pit.

Sump Pump Discharge Systems

The discharge pipe should carry water far enough from the foundation to reduce recirculation into the drainage system. It should also be protected from blockage, freezing, crushing, and damage from landscaping or vehicles.

Sump water should not be released where it can create erosion, cross property boundaries improperly, obstruct walkways, or enter prohibited systems. The discharge plan must reflect property conditions and applicable requirements.

Yard Grading and Regrading

Yard grading reshapes the land so that rainwater flows away from buildings and toward suitable drainage areas. Proper grading can reduce puddles, muddy ground, foundation saturation, landscape erosion, and runoff traveling in unwanted directions.

Grading may involve removing soil, adding approved fill, correcting low spots, establishing swales, improving transitions around patios and walkways, and restoring grass or landscaping after earthwork.

Foundation Grading

Soil immediately surrounding a building should generally direct surface water away from foundation walls. Settlement, erosion, landscaping changes, and construction activity can create low areas that trap water near the structure.

Foundation regrading may include adding and compacting suitable soil, reshaping the slope, adjusting landscape beds, correcting downspout discharge, and improving drainage paths. Soil should not be placed at a height that covers siding, masonry openings, vents, drainage gaps, or other building components that require clearance.

Low-Spot Correction

Low areas collect runoff from surrounding ground and may remain wet long after a storm. Correcting them may involve regrading, adding soil, installing a catch basin, building a subsurface drain, or combining several solutions.

Simply filling a low spot can move water to another part of the property. The complete flow path should be planned before elevations are changed.

Drainage Swales

A swale is a broad, shallow channel formed in the landscape to guide surface runoff. Swales may be covered with grass, stone, erosion-control materials, or vegetation selected for periodic water flow.

A properly shaped swale provides a continuous path without creating an abrupt ditch or directing water toward vulnerable structures. Width, depth, slope, soil, vegetation, and outlet conditions affect performance.

Final Grading and Landscape Restoration

After drainage installation, disturbed soil may require final grading, compaction, topsoil, seed, sod, mulch, or other surface restoration. Establishing vegetation helps stabilize exposed soil and reduce erosion while the property recovers from construction.

Catch Basin Installation

Catch basins collect surface water from low areas and direct it into underground drainage pipes. A basin has a grated opening that allows runoff to enter while helping block larger debris.

Catch basins are commonly installed in:

• Low areas of lawns
• Courtyards
• Driveways
• Patios
• Parking lots
• Landscape beds
• Areas below downspouts
• Walkways and entrances

The basin must be set at an elevation that allows water to enter without creating a trip hazard or interfering with mowing and maintenance. Pipe slope, basin size, grate type, expected flow, and discharge location should all be considered.

Catch Basin Cleaning and Repair

Sediment, leaves, mulch, trash, and other debris can collect inside a basin and restrict flow. Routine cleaning helps keep the outlet open. Cracked basins, broken grates, separated pipes, and settled components may require repair or replacement.

Channel and Trench Drains

Channel drains, also called trench drains, collect water across a narrow linear opening. They are useful where runoff crosses driveways, garage entrances, patios, pool decks, sidewalks, courtyards, loading areas, and commercial pavement.

The drain body, grate, outlet pipe, bedding, and surrounding pavement should be designed for expected water volume and traffic. A residential patio grate and a drain exposed to commercial vehicles require different load ratings.

Driveway Channel Drains

A channel drain positioned across a driveway can intercept water before it reaches a garage, building entrance, or low parking area. The system requires a stable foundation, properly rated grate, adequate outlet, and surrounding pavement that directs water toward the drain.

Patio and Pool-Deck Drains

Narrow channel drains can collect water along patios, outdoor living areas, pool decks, and door thresholds. Drainage design should account for finished surface slope, barefoot use, cleaning, debris, nearby landscaping, and safe discharge.

Downspout Drainage Systems

Roof gutters concentrate a large amount of rainwater at downspouts. If this water is released beside the building, it can saturate the foundation area, erode soil, wash away mulch, and create puddles.

Underground downspout drainage carries roof runoff through solid pipe to a suitable outlet, dry well, detention area, or other approved destination. Solid pipe is generally used so the collected roof water remains contained while being transported away.

Downspout Extensions

Above-ground extensions can move water farther from the foundation when site conditions allow. They should be positioned to avoid walkways, mowing paths, neighboring property, and areas where water can return toward the building.

Buried Downspout Lines

Buried drainage provides a cleaner appearance and protects the pipe from some surface activity. The line should have appropriate slope, durable fittings, accessible cleanout points when practical, and an outlet protected from blockage and erosion.

Downspout Drain Repair

Underground lines can clog with leaves, shingle granules, sediment, roots, or debris. They may also separate, collapse, freeze, or become damaged by vehicles and landscaping work.

Signs of a blocked downspout drain include gutter overflow, water backing up at an adapter, soggy soil along the buried line, and little or no discharge at the outlet.

Dry Well Installation

A dry well is an underground structure that temporarily stores runoff and allows it to soak into surrounding soil. It may receive water from downspouts, catch basins, channel drains, or other collection systems.

Dry wells are not suitable for every property. Their performance depends on soil infiltration, groundwater elevation, available space, separation from buildings and utilities, incoming water volume, pretreatment, and maintenance.

A dry well installed in poorly draining soil may remain full and cause the connected drainage system to back up. Soil evaluation and appropriate sizing are important before installation.

Surface Drainage Systems

Surface drainage manages water flowing across lawns, pavement, patios, and landscaped areas. Components may include grading, swales, catch basins, trench drains, curbs, inlets, and open channels.

Effective surface drainage requires a continuous path from the problem area to an acceptable destination. Drains placed in random low spots may collect some water without addressing the overall runoff pattern.

Subsurface Drainage Systems

Subsurface drainage manages water within the soil. It may be used where groundwater, hillside seepage, saturated soil, or water trapped above dense soil layers causes persistent wetness.

Common subsurface systems include:

• French drains
• Foundation drains
• Interceptor drains
• Perimeter drains
• Retaining-wall drainage
• Athletic-field drainage
• Landscape drainage
• Subsurface collection galleries

Subsurface drainage should use appropriate pipe, stone, fabric, slope, access points, and outlets. The depth and placement must match the source of the water.

Foundation Drainage

Foundation drainage helps control surface water and groundwater around basements, crawl spaces, slabs, and retaining walls. A complete approach may involve grading, gutters, downspouts, foundation drains, waterproofing coordination, sump pumps, and appropriate discharge.

Common signs of foundation drainage problems include:

• Water pooling beside walls
• Damp basement or crawl-space areas
• Water stains
• Efflorescence on masonry
• Musty odors
• Peeling coatings
• Soil erosion near the foundation
• Frequent sump pump operation
• Water entering after heavy rain

Moisture can enter a building through cracks, joints, penetrations, porous materials, windows, doors, drains, or openings around utilities. The source should be identified before selecting a drainage or waterproofing method.

Basement Drainage Systems

Basement drainage may involve exterior foundation drains, interior perimeter channels, sump basins, pumps, vapor-management systems, and repairs to specific entry points. Interior drainage typically collects water that reaches the foundation perimeter and redirects it to a sump system.

An interior system can manage water without stopping it outside the building. Exterior drainage and waterproofing may be more appropriate when access, structure, budget, and site conditions support that approach.

Crawl-Space Drainage

Water can enter crawl spaces through soil, foundation walls, vents, plumbing problems, grading, or downspout discharge. Persistent moisture can contribute to odors, wood deterioration, pests, and poor conditions beneath the building.

Crawl-space drainage solutions may include:

• Exterior grading improvements
• Downspout drainage
• Interior perimeter drains
• Sump pump systems
• Drainage matting
• Ground vapor barriers
• Access-well drainage
• Foundation opening repairs

Drainage should be coordinated with moisture-control and structural needs. A sump pump alone may not correct uncontrolled roof runoff or poor exterior grading.

Driveway Drainage

Driveways can direct large volumes of water toward garages, buildings, sidewalks, or neighboring areas. Low spots, incorrect slope, settled pavement, undersized drains, and blocked culverts can contribute to flooding and erosion.

Driveway drainage solutions may include:

• Channel drains
• Catch basins
• Driveway culverts
• Swales
• Regrading
• Pavement correction
• Drainage pipe installation
• Outlet protection
• Erosion-resistant stone

Patio and Outdoor Living Area Drainage

Patios, walkways, retaining walls, outdoor kitchens, and pool decks can alter the way water moves through a yard. Hard surfaces prevent infiltration and may send concentrated runoff toward doors, walls, planting beds, and adjoining properties.

Drainage improvements may include adjusting surface slope, installing channel drains, adding catch basins, creating swales, connecting downspouts, or replacing failed underground lines.

Retaining-Wall Drainage

Water accumulating behind a retaining wall can increase pressure, carry soil through openings, stain the wall, and contribute to movement or failure. Drainage provisions may include free-draining backfill, filter fabric, perforated pipe, drainage outlets, and properly directed surface water.

Visible seepage, leaning, cracking, bulging, soil loss, and persistent saturation may indicate drainage or structural problems. Structural concerns should be evaluated by an appropriately qualified professional.

Culvert Installation and Repair

Culverts carry water beneath driveways, roads, paths, and access areas. A culvert system may include the pipe, bedding, compacted fill, end treatments, headwalls, inlet protection, and erosion-resistant outlet materials.

Common culvert problems include:

• Sediment and debris blockages
• Collapsed or crushed pipe
• Separated joints
• Undersized capacity
• Erosion around the inlet or outlet
• Washouts around the pipe
• Poor elevation or slope
• Damaged headwalls
• Vegetation restricting flow

Storm Drain Installation

Storm drain systems collect and carry rainfall runoff through inlets, basins, pipes, manholes, channels, and outlets. They are separate from sanitary sewer systems and should be designed only for approved stormwater flows.

Storm drainage may be needed for commercial sites, parking lots, multifamily properties, private roads, courtyards, campuses, and large residential properties. Pipe capacity, inlet placement, surface grading, outlet conditions, maintenance access, and peak rainfall should all be considered.

Storm Drain Cleaning and Maintenance

Leaves, trash, sediment, gravel, mulch, roots, and construction debris can restrict stormwater systems. Preventive cleaning helps preserve flow capacity and makes damaged components easier to identify.

Stormwater maintenance may include:

• Catch basin cleaning
• Inlet and grate cleaning
• Pipe flushing
• Debris and sediment removal
• Root removal
• Outlet clearing
• Channel cleaning
• Culvert cleaning
• Drainage structure inspection
• Pipe repair and replacement

Drainage Pipe Repair and Replacement

Drainage pipes may clog, crack, separate, sag, collapse, or become filled with soil and roots. Flexible, thin-walled, or improperly bedded pipes may deform under soil or vehicle loads.

Drainage pipe services may include:

• Locating buried drain lines
• Video camera inspection where suitable
• Pipe cleaning and flushing
• Root and sediment removal
• Repairing separated connections
• Replacing collapsed sections
• Correcting inadequate slope
• Installing cleanouts
• Upgrading pipe size or material
• Rebuilding damaged outlets

Erosion-Control Services

Uncontrolled runoff can remove soil, expose roots, damage landscaping, undermine pavement, create gullies, and carry sediment into drainage systems. Erosion control slows, redirects, spreads, stabilizes, or safely releases moving water.

Possible erosion-control methods include:

• Grading and slope correction
• Drainage swales
• Riprap and stone armoring
• Outlet protection
• Erosion-control blankets
• Vegetation and ground cover
• Terracing
• Check structures
• Level spreaders
• Retaining systems
• Drainage pipe extensions
• Sediment-control measures

The selected method should address both the water source and the area being damaged. Placing stone over erosion without controlling concentrated flow may only provide temporary improvement.

Rain Gardens and Infiltration Systems

A rain garden is a landscaped depression designed to receive and temporarily hold runoff. Vegetation, engineered soil, mulch, stone, underdrains, and overflow structures may be used to slow water and encourage infiltration.

Rain gardens must be sized and positioned according to contributing drainage area, soil infiltration, groundwater, building separation, overflow paths, and plant requirements. They are not appropriate for every site or every drainage problem.

Retention and Detention Systems

Retention and detention systems manage larger volumes of runoff from roofs, parking areas, pavement, and developed property. Detention systems temporarily store water and release it at a controlled rate. Retention systems hold water for infiltration, reuse, evaporation, or permanent storage, depending on the design.

Systems may include:

• Surface basins
• Underground storage chambers
• Large-diameter pipes
• Vaults and tanks
• Outlet-control structures
• Emergency overflow paths
• Infiltration beds
• Pumps and controls

Commercial and engineered stormwater systems may require hydrologic calculations, civil engineering, permits, inspections, and ongoing maintenance.

Commercial Stormwater Services

Commercial properties often contain large roofs, parking lots, drive lanes, loading areas, sidewalks, and other impervious surfaces that generate concentrated runoff. Effective stormwater systems help keep entrances, pavement, work areas, and neighboring property usable during rainfall.

Commercial drainage services may include:

• Parking lot drainage
• Catch basin installation and repair
• Trench and channel drains
• Roof drainage connections
• Storm sewer installation
• Culvert systems
• Detention and retention systems
• Loading dock drainage
• Courtyard drainage
• Athletic-field drainage
• Drainage pipe cleaning and repair
• Erosion and sediment control
• Stormwater-system inspections
• Preventive maintenance

Parking Lot Drainage

Parking lots depend on surface slope, curbs, gutters, inlets, catch basins, trench drains, pipes, and outlets working together. Settlement, pavement repairs, clogged grates, damaged pipes, and excessive sediment can disrupt the intended drainage pattern.

Common signs of parking lot drainage problems include standing water, ice formation, ponding near entrances, overflowing basins, eroded landscape islands, pavement deterioration, and water crossing pedestrian routes.

Drainage Inspections and Troubleshooting

Drainage troubleshooting identifies the water source, flow path, affected areas, and reason an existing system is not working. The visible puddle is not always where the problem begins.

A drainage evaluation may consider:

• Roof and downspout discharge
• Property elevations and slopes
• Low spots and surface flow paths
• Soil type and infiltration
• Foundation conditions
• Existing drains, basins, and pipes
• Pipe slope and outlet elevation
• Neighboring runoff
• Groundwater and hillside seepage
• Pavement and landscape changes
• Erosion and sediment patterns
• Performance during rainfall

Drain Camera Inspection

A drainage camera can sometimes be used to inspect accessible underground pipes for roots, sediment, separations, deformation, and obstructions. Camera inspection has limitations when pipes are filled with water, severely clogged, crushed, corrugated, or too small for the equipment.

Drainage System Testing

Controlled water testing, elevation measurements, outlet inspection, and observation during rainfall can help determine how a drainage system performs. Testing should avoid overwhelming the system or releasing water where it could cause damage.

Common Signs of a Drainage Problem

Drainage problems may appear gradually or become obvious during heavy rainfall. Warning signs include:

• Standing water in the yard
• Persistent muddy areas
• Water collecting near the foundation
• Wet basement or crawl-space areas
• Overflowing catch basins
• Clogged or backing-up downspout drains
• Water entering a garage or doorway
• Erosion and exposed roots
• Washouts around driveways or culverts
• Settled patios or walkways
• Water stains on foundation walls
• Sump pumps running frequently
• Sinkholes along buried drain lines
• Algae and moss in consistently wet areas
• Water flowing across neighboring property
• Stormwater remaining long after rainfall ends

Why Drainage Systems Fail

Drainage systems may fail because the original design did not account for the amount of water, the pipe lacks adequate slope, the outlet is blocked, the soil has settled, or maintenance has been neglected.

Common causes of drainage failure include:

• Improper grading
• Undersized pipes or basins
• Collapsed or crushed pipe
• Insufficient pipe slope
• Clogged inlets and outlets
• Root intrusion
• Sediment buildup
• Disconnected fittings
• Inadequate foundation clearance
• Poorly placed French drains
• Dry wells installed in unsuitable soil
• Downspouts connected to perforated transport pipe
• Discharge points that are too close to buildings
• Unprotected outlets causing erosion
• Changes to neighboring land or pavement
• Lack of inspection and maintenance

The Drainage Installation Process

1. Property evaluation: Buildings, slopes, low areas, soil, pavement, landscaping, utilities, and existing drainage components are reviewed.
2. Water-source identification: Roof runoff, surface flow, groundwater, hillside seepage, pavement drainage, and other sources are identified.
3. Elevation assessment: Grades, pipe routes, inlet elevations, and potential outlets are measured.
4. System planning: Appropriate collection, conveyance, storage, infiltration, pumping, and discharge components are selected.
5. Requirement review: Utility locations, drainage rules, permits, easements, discharge restrictions, and other requirements are identified.
6. Site preparation: Work areas, excavation routes, material storage, and protection for buildings and landscaping are established.
7. Excavation and grading: Trenches, basins, slopes, swales, or storage areas are formed to the required dimensions and elevations.
8. Component installation: Pipes, stone, fabric, basins, pumps, channels, chambers, or erosion-control materials are installed.
9. Connection and discharge work: Inlets, outlets, cleanouts, overflow routes, and erosion protection are completed.
10. Testing: Accessible portions of the system are tested for flow, slope, pump operation, and proper discharge.
11. Backfilling and restoration: Trenches are backfilled, surfaces are graded, and disturbed lawns or landscape areas are restored as included.
12. Maintenance planning: Cleaning, inspection, pump testing, sediment removal, and seasonal service needs are established.

Drainage and Stormwater System Maintenance

Drainage systems require maintenance because sediment, leaves, roots, mulch, trash, ice, and vegetation can restrict water flow. Pumps and mechanical components also require testing and eventual replacement.

Routine maintenance may include:

• Cleaning catch basins and grates
• Removing debris from channel drains
• Flushing accessible drainage pipes
• Clearing downspout adapters
• Inspecting outlets for erosion or blockage
• Testing sump pump operation
• Testing battery backup systems
• Cleaning sump basins
• Inspecting check valves
• Removing sediment from swales
• Restoring eroded areas
• Checking dry wells and infiltration systems
• Inspecting culverts and end treatments
• Trimming vegetation around drainage structures
• Checking the system after major storms

Frequently Asked Questions About Drainage and Stormwater Services

What is the best way to fix standing water in a yard?

The right solution depends on the cause. Options may include regrading, a French drain, catch basin, swale, dry well, downspout correction, or a combination of methods. The source and destination of the water should be identified before installation begins.

How does a French drain work?

A French drain collects water from saturated soil through gravel and perforated pipe. The pipe then carries the water toward an appropriate outlet or collection point.

How deep should a French drain be?

Depth depends on the water source, soil layers, property slope, nearby structures, outlet elevation, and purpose of the system. A shallow yard drain and a foundation drain may require very different designs.

Can a French drain protect a basement?

A properly designed foundation or perimeter drainage system can help manage water near a basement. Some properties also require grading improvements, gutter drainage, waterproofing, crack repair, or a sump pump.

What is the difference between a French drain and a catch basin?

A French drain collects water from within saturated soil along a trench. A catch basin collects surface water at a specific low point through a grated opening. Many systems use both types of drainage.

Does a sump pump prevent all basement flooding?

No drainage or pumping system can guarantee that flooding will never occur. A sump pump can reduce water accumulation when it is properly sized, powered, maintained, and connected to a functional drainage and discharge system.

How often should a sump pump be tested?

A sump pump should be tested periodically and before expected wet seasons or severe storms. The pump, float, check valve, basin, discharge, power supply, alarm, and backup system should all be checked.

Why does a sump pump run constantly?

Frequent operation may result from high groundwater, heavy rainfall, a stuck switch, undersized pump, failed check valve, leaking discharge pipe, or water returning to the foundation because the outlet is too close.

Can downspouts be connected to a French drain?

Roof water is generally transported through solid pipe rather than being released directly into a perforated French drain line. The systems may share a suitable outlet when properly designed, but connections should not overload the subsurface drain.

Will regrading solve every yard drainage problem?

Regrading can correct many surface-flow problems but may not resolve groundwater, hillside seepage, dense soil, or water trapped by pavement and structures. Some properties require grading combined with drains, basins, pumps, or infiltration systems.

What is the difference between a dry well and a catch basin?

A catch basin collects water and sends it through a pipe. A dry well stores water underground and allows it to infiltrate the surrounding soil. A catch basin may discharge into a dry well when soil and site conditions are suitable.

Why does an underground drain keep clogging?

Recurring clogs may result from unprotected inlets, leaves, sediment, roots, insufficient slope, crushed pipe, poor fittings, or an outlet that remains submerged or blocked.

Can drainage water be directed toward the street?

Allowable discharge locations vary. Water should not be redirected in a way that creates hazards, damages neighboring property, overwhelms public systems, or violates drainage requirements. The outlet must be planned for the specific property.

What is the difference between stormwater and sewage?

Stormwater is runoff from rain and melting precipitation. Sanitary sewage contains wastewater from plumbing fixtures. The two systems serve different purposes and should not be improperly connected.

Can drainage systems damage underground utilities?

Drainage installation requires excavation, so underground utilities should be identified before digging. Pipe routes, dry wells, pumps, and grading plans may need to be adjusted around existing services.

What affects the cost of a drainage project?

Cost factors include the type and source of the water problem, system length and depth, soil, access, pipe size, stone quantity, basins, pumps, outlet requirements, pavement removal, utility conflicts, excavation, grading, hauling, and landscape restoration.

Reliable Water Management for Homes and Businesses

A successful drainage system controls water from the point where it collects to the place where it can be safely discharged, stored, or absorbed. Solving only the visible puddle without understanding the complete flow path can move the problem rather than correct it.

Professional drainage planning brings together roof runoff, surface grading, subsurface water, foundation conditions, soil, pavement, landscaping, pipes, pumps, storage systems, and discharge requirements. Whether the solution involves a French drain, sump pump, yard grading, catch basin, channel drain, dry well, culvert, storm drain, or erosion-control system, careful design and installation help create drier, more usable, and better-protected property.
