Sewage Tank and Sump Pit Cleaning The term “septic” relates to the anaerobic bacterial system that develops within the tank and causes the waste that is discharged into the tank to decompose or mineralize. A poorly-maintained septic tank/sump pit tank will become a serious health hazard, spreading disease and contaminating water sources – so maintenance and regular cleaning of your septic/sump pit tank is crucial! We have a range of bulk waste removal vehicles sized to suit all requirements from residential buildings, Labor camps, and commercial buildings to large industrial premises and also personnel to manually clean and dispose the collected waste. Regular, preventive maintenance is required to remove the irreducible solids which settle at the bottom of the septic/sump pit tank, reducing its capacity and efficiency.
