Holding tank

Wastewater holding tank is an enclosed container designed to collect and temporarily store wastewater in places where the use of wastewater treatment systems is limited or impossible. Within the frameworks of VillageWaters Project chemical toilets (Portaloo, TOITOI, Honey Bucket etc.) are considered as storage tanks too, since they do not have output to environment.

Main characteristics
Holding tanks are used to collect and temporarily store sewage from a facility or dwelling for later removal and transport to municipal WWT plant for treatment. These WWT solution is postponed wastewater treatment solution.


Basic principles of operation
Wide variety of holding tanks are available on market. The storage capacity of a holding tank depends on daily sewage flow and emptying frequency. The operation of small holding tanks is manual. Bigger tanks are usually equipped with filling alarm system.


The difference between holding tank and cesspool, which externally seems similar, is the insulation level. According to its construction cesspool is not watertight and allow liquid to leach out from pit. Therefore cesspools could be considered as the older version of holding tanks and used only in cases when such impact to environment is allowed and acceptable.
