STP Tank Cleaning and Desludging in Bangalore
Every sewage treatment plant builds up sludge and solids that have to be removed. When this is skipped, the plant starts smelling, treated water turns cloudy and KSPCB samples fail. Reshma Facilities Management cleans STP tanks and removes sludge safely, with disposal records the association can show during an inspection.
STP tanks we clean
Tank | Why it needs cleaning |
|---|---|

Clarifier or settling tank | Settled sludge that has not been removed |

Frequently asked questions
Collection tanks usually need cleaning every few months. Aeration and clarifier sludge is removed on a schedule set by plant size and load, often monthly or quarterly.
We plan the clean to keep the plant running where the design allows. Some plants need a short shutdown.
Properly dried and stabilised STP sludge is often used as garden manure within the property.
