Wastewater assets and cleaning considerations

Wet wells, aeration tanks and sludge stores do different jobs within a treatment system. Their contents and equipment, together with inflow and shutdown limits, affect how cleaning is planned and what has to stay in service.

Process role: what the tank does and which treatment stages sit before and after it.
Contents: the wastewater present, retained solids and any known industrial input.
Equipment: pumps, mixers, screens and other components affected by cleaning.
Operations: normal inflow, permitted shutdown and the conditions for return to service.

Intermittent storage

Storm storage tanks

Storm storage tanks provide temporary capacity in wastewater systems. Sediment can remain after filling, and changing weather or inflow can affect both cleaning and return to service.
