Retain and release of stormwater to recharge groundwater

High quality precast concrete drywells augment stormwater systems by retaining captured runoff during storm events up to a specified volume and then incrementally releasing it through infiltration to recharge groundwater. Jensen Precast drywells are designed to custom fit new stormwater infrastructure projects or interconnect with existing drainage systems.

How It Works

  1. Captured stormwater runoff is received post-treatment in a precast concrete drywell structure.
  2. Drywell structure incrementally releases treated stormwater runoff.
  3. Released water infiltrates into ground and recharge groundwater.
