A pump-storage device includes a tank, a treatment container, and a vacuum pump. The treatment container includes a first chamber in communication with an inlet. The first chamber includes a bottom wall having a first valve intercommunicated with a second chamber. The second chamber includes a bottom wall having a second valve. The treatment container includes a first control valve having a first duct in communication with the first chamber, a second duct in communication with the second chamber, and a third duct in communication with the tank. The treatment container includes an actuation cylinder for actuating an actuation rod to extend or retract. A first valve plate and a second valve plate are mounted on the actuation rod for controlling opening and closing of the first valve and the second valve. The treatment container includes a second control valve in communication with the first chamber and the vacuum pump.

The invention relates to a building basement flood control system that eliminates termination of sanitary and storm sewer lines within a building. The control system includes a sanitary sewage basin system and a storm water sump pit installed in the basement floor. A sewage pump in the sewage basin pumps sewage through a discharge pipe extending to the exterior of the basement wall for discharge into an open end of an above ground vertical sanitary sewer line adjacent an exterior basement wall. The control system further includes a storm water sump pit installed in the basement floor. A sump pump in the sump pit pumps storm water through a discharge pipe extending to the exterior of the basement wall for discharge into an open end of an above ground vertical storm sewer line adjacent the exterior basement wall.

A French drain drainpipe with built-in means for flushing iron ocher out of the drainpipe, out of the perforations, and out of the gravel surrounding the drainpipe. Said means may include chambers for receiving pressurized washing fluids and exit orifices from the chambers. Fittings are provided for connecting the chambers to a pressurized source of washing fluids, such as hose fittings for connecting to a normal household water supply.

A contamination unit for isolating a building from contamination of a sewer is disclosed. The contamination unit includes a housing with an inlet and an outlet, a trap assembly, and a fluid trigger. The inlet is in fluid communication with a fluid source, plumbing equipment, and/or condensating equipment to receive fluid. The housing has a reservoir to collect the fluid therein and to define a reservoir portion of a contamination barrier about the outlet. The trap assembly includes a trap conduit between the outlet and the sewer that is shaped to collect the fluid therein and define a trap portion of the contamination barrier. The fluid trigger is positionable about the housing to selectively release the fluid through the inlet and into the reservoir of the housing whereby the fluid in the contamination barrier is maintained to prevent the contamination from passing from the sewer into the building.

A clean out notification disc is placed in a clean out underneath a clean out cover to provide a durable notification mechanism of certain conditions of a main sewer line, such as, for example, the existence of a sewer liner, a backflow valve or a grease trap.

The disclosure discloses an integrated riparian system for river/lake silt on-site treatment and application thereof, belonging to the technical field of silt treatment. The integrated riparian system includes three subsystems, namely a silt ecological treatment subsystem, a siphon drainage subsystem and a silt leachate advanced treatment subsystem. The silt ecological treatment subsystem is provided with plants, fillers, an aeration pipe and a water collection pipe from top to bottom, and a vent pipe is connected to the water collection pipe. A siphon in the siphon drainage subsystem is retractable and hump-shaped. The silt leachate advanced treatment subsystem includes a first-stage ecological treatment unit upflow wetland and a second-stage ecological treatment unit surface flow wetland. According to the disclosure, dewatering and harmlessness of silt, advanced treatment of silt leachate and purification of part of river/lake water are effectively realized through transpiration and absorption of the plants, filtration and adsorption of the fillers and degradation of microorganisms.
