A regulating tank includes a tank member having an annular wall to receive wastewater. A circular pipe is connected to the tank member. A draining device drains the wastewater in the tank member to the circular pipe. A plurality of nozzles connected to the circular pipe to eject the wastewater in the circular pipe back to the tank member. When the wastewater is ejected by the nozzles, a temperature of the wastewater is reduced, and dissolved oxygen of the wastewater is increased.

A pressure sewer control system includes a server in communication with one or more pressure sewer installations across a communications network, each of the one or more pressure sewer installations including a controller and one or more sewerage tanks. The server is configured to: determine weather data for a region associated with the pressure sewer installation; estimate power generating capability of a weather-dependent power generator based on the weather data; receive fluid level data indicative of a fluid level in the one or more sewerage tanks from the controller; determine whether a pump action should be instigated by the controller to pump fluid from the sewage tank based on the estimated power generating capability of the weather-dependent power generator and the fluid level data; and transmit a pump control instruction to the controller.

A catch basin trap for mounting in an opening in a side wall of a catch basin. A preferred catch basin trap has a body with a front side for facing outwardly to outside of the catch basin, and a back side for facing inwardly to inside of the catch basin. An inlet opening is provided in the back side of the body for receiving drainage water from inside of the catch basin. An outlet opening is provided in the front side of the body for discharging the drainage water to the outside of the catch basin. A flexible outlet pipe connector extends outwardly from the outlet opening, configured for watertight coupling to an outlet pipe positioned outside of the catch basin. The catch basin trap provides a water flow path for drainage water from inside of the catch basin to the outlet pipe. A preferred outlet pipe connector is adapted to facilitate installation of the catch basin trap by allowing watertight coupling to the outlet pipe at a plurality of angles and positions relative to the catch basin trap, and to accommodate angular and transpositional deviations of the outlet pipe resulting from settling of the ground after installation.

In a system and method for retaining or detaining a fluid beneath a ground surface, a plurality of modules, each having at least one vertically disposed side portion supporting a horizontally disposed roof are provided. The plurality of modules, each being in fluid communication, either directly or indirectly, with each of the other modules, are arranged in an assembly having a plurality of rows and columns. Each of the rows and columns contain at least one flow obstructer such that fluid flow through each of the rows and columns is circuitous.

A grease trap or solids collector for separating waste from waste water has a tank having a multilayer outer wall made of an outer layer of un-foamed plastic, an intermediate layer of foamed plastic, and an inner layer of unfoamed plastic; an inlet invert in the tank for receiving incoming waste water; and an outlet invert for removing water from the tank. An extension collar made up of segments can be included.
