Patent ID: 8561633

Claim:
A steel-reinforced high-density polyethylene (HDPE) rain harvesting system, comprising: a cylindrical wetwell fabricated from steel-reinforced plastic; an HDPE filter platform disposed inside the wetwell; a pervious concrete manhole structure attached to and supported by the HDPE filter platform inside the wetwell; a replaceable filter cloth lining the pervious concrete manhole structure; an HDPE sleeve mounted outside of the wetwell; a pump disposed in the HDPE sleeve; a Tee connector having a leg connected to the pump and extending through the wetwell and axially, the Tee connector having aligned legs exterior to the wetwell; an effluent pipe attached to the axially aligned legs of the Tee connector outside the wetwell, the effluent pipe allowing effluent water to be pumped to a target location; an effluent HDPE riser assembly, the riser assembly including an access hatch, the effluent HDPE riser assembly extending upward from an upper surface opening proximate an effluent end of the wetwell; an inlet pipe extending into the wetwell, the inlet pipe being adapted for receiving rain water, the inlet pipe providing for entry of the rain water inside the pervious concrete manhole structure of the wetwell; and a first water level monitor disposed in the wetwell, the first water level monitor being connected to the pump for activating the pump when water level in the wetwell exceeds a first predetermined level and deactivating the pump when water level in the wetwell falls below a second predetermined level.
