As the reactors appear to have holes around the bottom, the water dissolved the water-soluble fission products, which then accumulated in the basement of the turbine building (see the adjacent diagram) through any leaks from the water-injected reactor buildings. Since the accumulated radioactive water was a risk, TEPCO tried to transfer it.
The National Association of Clean Water Agencies has compiled a list of articles and municipal documents regarding wipes. In large sewage pump stations, clogging problems are often avoided by installing a chopper pump in the tank. A chopper pump is able to handle larger/tougher solids than a residential grinder pump, and may be able to process ...
A trap primer (or trap seal primer) is a plumbing device or valve that adds water to traps.The water seals in traps are needed to prevent sewer gases from entering buildings, but because this water is exposed to the air, it is subject to evaporation over time in infrequently used floor drains, leading to the release of sewer gas into the environment.

A dry well or drywell is an underground structure that disposes of unwanted water, most commonly surface runoff and stormwater, in some cases greywater or water used in a groundwater heat pump. It is a gravity-fed , vertical underground system that can capture surface water from impervious surfaces , then store and gradually infiltrate the ...
River Basin Management Plans are a requirement of the Water Framework Directive [1] and a means of achieving the protection, improvement and sustainable use of the water environment across Europe. This includes surface freshwaters (including lakes, streams and rivers), groundwater, ecosystems such as some wetlands that depend on groundwater ...
"My bathroom is just full of everybody's feces. The tub, filled with feces. There's mildew, mold coming down the wall," Shepherd said. Shepherd (pictured below) lives in the apartment with her ...
Much like a straw in a glass draws liquid, the pump draws liquid (including free-product) and soil gas up the tube in the same process stream. Pumping lifts LNAPLs, such as oil, off the top of the water table and from the capillary fringe (i.e., an area just above the saturated zone, where water is held in place by capillary forces).
