Capture Stormwater Before It Floods Yards
Drainage Pits & Dry Wells in Virginia Beach for properties with recurring standing water and basement seepage
Heavy rainfall in Hampton Roads can overwhelm yard surfaces quickly, leaving water standing for days in low areas and saturating soil near foundations. East Coast Drainage and Landscaping LLC designs dry wells based on your specific roof runoff volume and soil drainage characteristics, creating underground reservoirs that capture thousands of gallons during storms and release it gradually through percolation. These systems integrate with downspouts and French drains to manage water from multiple sources, and pump stations provide backup protection in areas where gravity drainage alone can't move water away fast enough.
Dry well design starts with calculating how much water your roof sheds during typical Hampton Roads storm intensities and testing how quickly your soil absorbs moisture. A properly sized dry well includes perforated chambers surrounded by drainage stone, allowing stormwater to spread into the surrounding soil over hours instead of flooding your yard in minutes. Where soil drainage is poor or the water table sits high, pump stations activate automatically to discharge captured water to a suitable outlet when the dry well reaches capacity.
Arrange a drainage consultation to evaluate your property's runoff patterns and soil conditions.
Installation involves excavating a pit large enough to hold the calculated stormwater volume, installing perforated chambers or gravel-filled voids that create storage space, and connecting inlet pipes from downspouts, French drains, or surface catch basins. The system sits entirely underground with only access lids or pop-up emitters visible at grade. Pump station installations include a sealed basin, submersible pump, and discharge line that carries overflow away from your property when the dry well fills beyond its percolation capacity.
Once operational, areas that previously stayed wet for 48 hours after storms dry within several hours because water drains into the dry well instead of pooling on the surface. Your yard remains usable after rain events, grass grows thicker in formerly waterlogged zones, and foundation walls stay dry because roof runoff and surface water divert away before saturating perimeter soil. Pump stations cycle on only during extreme rainfall, handling the overflow that exceeds what the dry well and soil can absorb naturally.
These systems work for decades with minimal maintenance, though access points should remain clear for periodic inspection. Complete drainage management may combine dry wells with French drains that intercept groundwater and downspout extensions that prevent roof runoff from overwhelming surface areas before it reaches the dry well.
Answers to Frequent Service Questions
Property owners typically want to understand system sizing and how the components work together during storms.
How do you determine the right dry well size?
The calculation considers your roof square footage, local rainfall intensity data, and soil percolation rate measured through on-site testing—clay soil requires larger storage volume because water percolates slowly, while sandy soil allows smaller dry wells that empty faster.
What happens during back-to-back storms when the dry well is already full?
Properly designed systems include enough storage for typical storm intervals, but pump stations handle situations where soil hasn't absorbed the previous storm's water before new rainfall arrives, discharging overflow to prevent yard flooding.
Where does the pump station discharge water?
The pump line typically runs to a street drainage inlet, drainage easement, or lower yard area where water can disperse without affecting neighboring properties or creating erosion.
Why do some properties need pump stations while others don't?
Pump stations become necessary when your lot sits lower than surrounding properties, soil drains very slowly, or no gravity outlet exists to move water away—conditions common in low-lying Norfolk and Virginia Beach neighborhoods.
How does this integrate with existing downspout extensions?
Downspout extensions can feed directly into the dry well inlet, or they can discharge to separate pop-up emitters if your dry well is sized primarily for French drain water rather than roof runoff.
