Drainage to Rainwater Adaptor - 110mm to 68mm

This 110mm to 68mm reducer is used to introduce a circular rainwater downpipe into a 110mm drainage pipe, allowing rainwater collected from roofs by gutters to flow into the underground drainage system.

This is particularly useful in a stormwater infiltration system where rainwater is fed underground into a silt trap to remove any sediment before it flows into a soakaway crate wrapped in membrane. The clean stormwater is then distributed into the surrounding soil at a controlled rate to prevent flooding.
