A stormwater collection, treatment, and aquifer replenishment installation includes a stormwater drain for receiving surface stormwater, a dry well downwardly extending underground to an outlet proximate to a water table over an aquifer, a tank structure at least partially disposed underground and coupled with the stormwater drain and the dry well in stormwater communication, a stormwater treatment system enclosed within the tank structure between the stormwater drain and the dry well for converting surface stormwater into treated stormwater, the tank structure for conducting surface stormwater to the stormwater treatment system between the stormwater drain and the dry well, and the dry well for receiving and gravity feeding treated stormwater from stormwater treatment system to the outlet.

A drain assembly for installation in a shower floor, the drain assembly including a drain body including an upper surface defining a top side, and a lower surface opposite the upper surface defining a bottom side. The drain assembly also defines an aperture extending along an axis through the drain body between the upper surface and the lower surface and includes an outlet having a flange and an elongated body. When assembled, the elongated body is configured to extend below the lower surface of the drain body when the flange rests on the upper surface. The drain assembly also includes one or more fasteners configured to couple the outlet to the drain body to form a water-tight seal therebetween, where each of the one or more fasteners are accessible from the top side.

In one aspect the present invention provides an adjustable head infiltration conduit configured to distribute water adjacent to the conduit and to convey water away from the conduit. This conduit includes a conveyance chamber defining a water flow path through the conduit, and at least one inlet port associated with one end of the water flow path defined by the conveyance chamber. Also provided is at least one outlet port associated with an end of the water flow path distal from said at least one inlet port, and an infiltration chamber in fluid communication with the conveyance chamber. This infiltration chamber includes at least one water permeable area configured to allow water out of the conduit. The infiltration chamber also includes at least one removable intermediate lateral baffle orientated substantially perpendicular to the water flow path defined by the conveyance chamber with the upper edge of said at least one removable intermediate lateral baffle defining the boundary of the infiltration chamber with the conveyance chamber. The removable intermediate lateral baffle or baffles forming at least two retention cells within the infiltration chamber arranged to temporarily store water before dispersal through at least one water permeable surface of the infiltration chamber.

A drain protector having a flexible adsorbent pad, a raised insert, and a cover is described. The pad and the insert each includes aligned apertures. The raised insert is positioned over the flexible adsorbent pad or within the aperture of the flexible adsorbent pad. The cover is connected to the flexible adsorbent pad, a raised insert, forming a space over the insert. The drain protector is made from adsorbent material for blocking sediment, collecting contaminants and filtering water into a drain. The cover of the drain protector reinforces the sheet and insert to protect against damage from traffic over the drain protector.

Provided is a separator comprising a chamber having a chamber wall opening, and an inlet module comprising an attachment portion and a projecting portion, the attachment portion is coupled to the chamber wall and comprises an inlet for receiving liquid, the projecting portion comprises an outlet configured to create a circulating flow about a central axis of the chamber, the projecting portion is offset from the attachment portion, a first wall is formed between the projecting portion and the chamber wall, a second wall opposes the first wall, a first side wall and a second side wall oppose each other and connects the first and second walls, the second side wall is continuous and the first side wall defines the outlet, the outlet is directed tangentially with respect to the central axis and wherein liquid exits the inlet module in a tangential direction with respect to the central axis.

A promenade drain for installation on a surface. The promenade drain including a base at least partially defining a channel and an outlet, a connector couplable to the base to form a first joint therebetween, a grate defining one or more apertures, and a frame. The frame, in turn, includes a second sliding surface configured to slide relative to a first sliding surface of the connector, and where the frame can be rotated with respect to the base without influencing the first joint.

A plastic component for use in a tiled wet environment can include a base structure comprising a first polymer material, and an integrated bonding interface formed on the base structure. The integrated bonding interface includes a second polymer material welded to or fused with the first polymer material of the base structure at a boundary area. A plurality of aggregate particles partially embedded in a mortar facing surface of the second polymer material to form a three-dimensional surface adapted for capturing or locking mortar material in one or more spaces on the integrated bonding interface between the aggregate particles.

A concrete form for installing a bath filler includes a base having an exposed top surface, a perimeter wall extending along each side of the base and oriented perpendicular to the base, and a rim extending from a top edge of the perimeter wall outwardly from the exposed top surface. The concrete form includes at least one notch disposed along the rim, such that the at least one notch is configured to align with a desired location of the bath filler. The concrete form includes a drill template corresponding with the notches. The drill template includes a plurality of markers configured to indicate drill-hole placement.

A sump overflow protection system for use in a building having a floor and a drainage field for collecting water from the perimeter of the building. The sump overflow protection system includes a portion of the floor proximal an opening of a sump crock having a first level defining a base and wherein the rest of the bottom floor generally has a second level higher than the first level of the basin surface of the floor and communicates water overflowing the sump crock to an outlet coupled to a building drainage outlet separate from the sump crock and to be located in the basin surface of the floor and spaced a predetermined distance from the sump crock.
