A silt trap is a method of preventing silt from entering and damaging a soakaway, attenuation or sewer system. These systems are designed to collect and remove surface water, either by emptying it into the sewer system, or by allowing it to drain back into the ground below.

What is silt arrestor pit?

The range of Ecosol Silt Arrestors provide a purpose designed and built underground storage pit where water that is contaminated with suspended sediment. Suspended solids (silt and sediment) from surface run-off are conveyed to the Ecosol Silt Arrestor typically by a conventional drainage pipe.

How do you clean a silt pit?

To clean, remove the Silt Trap Lid and lift the Primary Filter Bucket out of the Silt Trap Body and empty the Solids into an appropriate Waste Bin. Remove any residue materials found inside the Silt Trap Body that may have bypassed the Primary Filter Bucket.

Do you have to have a silt pit for a stormwater system?

Any drainage system should have silt pits at regular intervals. This includes both stormwater systems and agricultural drains. In the case of the above photo this is a combination drain and grate silt pit. (As the water can become stagnant this is a potential breeding ground for mosquitos!)

What is the particle retention rate of a silt pit?

This is a complete unit ready to be concreted into the floor. It includes the grate and uni-seal (pipe seal) and has a treatable flow rate of 5L/sec. With particle retention capabilities greater than 99% removal of particles >3mm in size the unit is highly effective whilst allowing water to freely flow.

Do you need a silt pit for a retaining wall?

Drainage, Retaining Walls. Any drainage system should have silt pits at regular intervals. This includes both stormwater systems and agricultural drains. In the case of the above photo this is a combination drain and grate silt pit.
