    摘要: A wastewater leaching chamber having asymmetric corrugations running transversely along the length of the chamber, where each transverse corrugation has a wide section on one side and a narrow section on the opposed side of the chamber, such that the corrugation walls run at an angle to the longitudinal axis of the chamber. The widest corrugation side of the chamber has a large straight sidewall, and the corrugation forms an arch which curve across and downward from the top of the straight sidewall to the narrow side of the corrugation at the opposing base of the chamber. The asymmetric arch is comprised of a multi radius curve from the top of the straight side to the opposing base footer.

    摘要: The invention is directed towards decoupling tidal effects from time-series depth measurements. A drainage sensor includes a fluid depth sensor. The drainage sensors are positioned at monitoring points in a drainage system. Stormwater flows into an input of the drainage system. A tidal depth sensor is positioned in a tidal body of water near an output of the drainage system. During period of high tide, tidal water backflows into the output of the drainage system. The decoupling is accomplished by generating a model of tidal backflow patterns based on data from the drainage sensors and the tidal sensor. The model accounts for a lag time between the tidal data measurements and measurements of the drainage sensors. The model is be used to predict the contribution of tidal backflow effects to stormwater data.

    摘要: A disclosed corrugated end cap includes a corrugated frame having one or more corrugations defined by one or more sets of alternating peaks and valleys. The end cap also includes one or more ribs disposed in one or more of the valleys and one or more valley reinforcements disposed in the valleys and running over a top surface of the corrugated frame. For example, the one or more ribs may be configured to increase a resistance of the frame to bending. Additionally or alternatively, the top surface, a front surface, and a rear of the corrugated frame surround a recess configured to receive latch ridges from a stormwater chamber.

    摘要: The invention provides a modular unit or module (20) for use in an underground water management system. The modular unit or module (20) comprises a prism structure being a polyhedron enclosing a pair of internal members (6, 6′). The internal members (6, 6′) comprise a first member (6) comprising a first arch (9), and a second member (6′) comprising a second arch (9′) located at an angle to and being arranged inverted with respect to the first arch (9). The invention also provides a modular system (100) for use in underground water management, the modular system (100) comprising a plurality of the modules or modular units (20, 20′).

    摘要: A stackable baffle drop shaft unit and method provides a pre-cast body that has a peripheral wall extending thereabout and having a top edge and an opposing bottom edge, the peripheral wall has an exterior facing surface and an opposing interior facing surface, and the body defines a medial channel extending therethrough between the top edge and the bottom edge. A baffle is carried by, and extends inwardly from the interior facing surface and partially across the medial channel defined by the body, and the baffle is positioned between the top edge and the bottom edge. The top edge and the bottom edge of the pre-cast body each define a portion of a positionally securing engagement and alignment means for positional and vertical alignment and stacking of plural units on top of one another. Vertical stacking of plural bodies forms a medial channel extending therethrough.
