Holding Tank Cleaning
Holding Tanks are usually used as detention tanks to store storm water or sewerage water and then discharge it at controlled rates to the downstream drainage system or public sewers. This includes rainwater detention tanks, dry & wet wells at pump stations, septic tanks etc.
Huge holding tanks are also used at water treatment plants and water reclamation plants for sludge settlement. Holding tanks for storm water and sewerage water is usually located underground – this could be a pit or a deep underground chamber – and sludge holding tanks are located above ground for facilitating the removal of sludge for disposal.
