Sump pumps are used where basement flooding may otherwise happen, and to solve dampness where the water table is near or above the foundation of a structure. Sump pumps send water away from a location to any place where it is no longer problematic, such as a municipal storm drain, a dry well, or simply an open-air site downhill from the building (sometimes called "pumping to daylight").
A discharge of wastewater causes the AAV to open, releasing the vacuum and allowing air to enter the plumbing vent pipe for proper pressure equalization. Since AAVs will only operate under negative pressure situations, they are not suitable for all venting applications, such as venting a sump, where positive pressures are created when the sump ...
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 ...
If this is insufficient, or in the case of failure of the pumping station, a backup in the sewer system can occur, leading to a sanitary sewer overflow—the discharge of raw sewage into the environment. Sewage pumping stations are typically designed so that one pump or one set of pumps will handle normal peak flow conditions. Redundancy is ...
However, with the sump pump example, the water is coming from another property, so you may need to investigate if you can collect damages from your neighbor's homeowners insurance company.
The discharge is found from a water balance. [2] The depth is selected in accordance to aquifer properties. The well filter must be placed in a permeable soil layer. The spacing can be calculated with a well spacing equation using discharge, aquifer properties, well depth and optimal depth of the water table.
