Our sediment tanks provide a basic and quick solution for on-site water

Sediment tanks come with an 50mm male camlock inlet. The 100mm uPVC flexible outlet is gravity feed to stormwater or kerb location . The tank is fitted two (2) bottom desludging valves to allow for simple installation and quick and easy desludging operation. Sediment tanks are also supplemented with chemical dosing block to enhance the settling rates, effectively reducing Total Suspended Solids (TSS). Units are available in 5,000 litre and 6,000litre tanks.

Ideal for the treatment of on-site water containing Heavy Suspended Solids.

The slower the flow the more efficient the tank operates .
