Quick Answer
Create a diversion ditch to redirect water flow away from a spring, using a shallow trench (about 1-2 feet deep and 1-2 feet wide) with a gentle slope (about 1:10) to allow water to flow smoothly, then direct the flow into a collection channel or pool.
Digging the Diversion Ditch
When digging the diversion ditch, start by identifying the source of the water and the desired direction of flow. Use a shovel to dig a shallow trench, about 1-2 feet deep and 1-2 feet wide, with a gentle slope of about 1:10 to allow water to flow smoothly. This slope will also help prevent erosion and ensure that the water flows consistently into the collection channel or pool.
Constructing the Collection Channel
Once the diversion ditch is dug, construct a collection channel or pool to capture the water. This channel should be designed to handle the expected water flow, taking into account the size of the spring and surrounding terrain. A good rule of thumb is to design the channel with a capacity of 1-2 cubic feet per second (CFS) for every 10 square feet of catchment area. The channel should also be lined with a durable material, such as gravel or concrete, to prevent erosion and ensure a smooth water flow.
Installing a Check Valve and Outlet
To prevent backflow and ensure a steady water supply, install a check valve at the outlet of the collection channel. This valve should be designed to allow water to flow out of the channel while preventing water from flowing back in. The outlet should also be designed to direct the water into a suitable location, such as a pipe or hose, for use in spring development.
