What is a

Two-Stage Ditch?

This image shows the conventional trapezoidal one channel shape of a ditch for surface water drainage. This shape suffers from premature erosion of material in to the ditch and poor drainage during high and low water volumes events.

​

A Two-Stage ditch shown in this cross section is a modification that introduces a lower main channel and a bench within the upper channel. The lower main channel transports water during low flow events more effectively while the upper channel is for when there are high flow water events.

The Ditch Doctor® method

The Ditch Doctor method

The unique Ditch Doctor® method can create, restore and maintain a Two-Stage ditch with a rounded shaped First Stage (Lower Main Channel) that transports water more effectively during low flow events. The Ditch Doctor® method does not disturb the vegetation on the benches or slopes that help reduce erosion back in to the lower main channel. As a result the Second Stage (Upper Channel) is better able to manage the high flow events.
