Pumping stations are designed to move water or sewage from one location to another, overcoming gravitational challenges, and are essential for maintaining navigable canal levels, supplying water, and managing sewage and floodwaters. In canal systems, pumping stations help replenish water lost through lock usage and leakage, ensuring navigability.
Caesium-137 concentration in the air, 19 March 2011. Radioactive materials were dispersed into the atmosphere immediately after the disaster and account for most of all such materials leaked into the environment. 80% of the initial atmospheric release eventually deposited over rivers and the Pacific Ocean, according to a UNSCEAR report in 2020.

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.
A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power.
The drainage system collects any water entering the basement and drains it to an internally placed sump pump system, which will then pump the water out of the basement. The Federal Emergency Management Agency (FEMA) recommends basement waterproofing with a water alarm and "battery-operated backup pump" as a preventive measure against the high ...
In the example of Belgium, a lowering of the water table by 100 meters has been the result. [ 7 ] [ 8 ] The freshwater that is accumulated by the system is then piped to the sea. In areas where this is a concern, vacuum sewers may be used instead, due to the shallow excavation that is possible for them.
A water stop, some gravel and a french drain may need to be used to prevent water from entering the basement at the bottom of the wall. Walls below grade may need to be sealed with an impervious coating (such as tar) to prevent water seepage. A polyethylene of about 6 mil serves as a water barrier underneath the basement.
