A septic drain field, a septic tank, and associated piping compose a septic system. The drain field typically consists of an arrangement of trenches containing perforated pipes and porous material (often gravel) covered by a layer of soil to prevent animals (and surface runoff) from reaching the wastewater distributed within those trenches.

A sump in a basement can be built in dry well form, allowing the sump pump to cycle less frequently (handling only occasional peak demand). A French drain can resemble a horizontal dry well that is not covered.
In 2017, Pennsylvania American Water, our state's largest owner and operator of water and wastewater systems, acquired a municipal-run sewer system in McKeesport in Allegheny County.
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 cost of flooding. [2] Wall conduits (such as dimple boards or other membranes) are fastened to the foundation wall and extend over the new drainage to guide any moisture ...
The primary disadvantage associated with the two stage drainage ditch is the upfront cost of the earthwork necessary to increase the existing channel for the benches to be constructed. Construction costs for such earthwork are contingent upon the watershed size and depth of the ditch and approximately range from $5–20 USD/linear foot. [6]
“The cost of reconstruction is about 250 times more than that of preservation activities on average.” Fixing Tacoma’s bad streets would cost billions. That’s right, billions -- with a ‘B’
Shull and other Nagel District trustees had tried to fix the problems since 2012, spending $700,000 on engineering studies, soil tests and failed repairs. The levee remained too weak.
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").
