How to Create a Diversion for Surface Water to a Spring?

Choosing the Right Location

When creating a diversion for surface water to a spring, it’s essential to choose the right location. Look for a spot where the surface water naturally flows or collects, and where the spring is easily accessible. Ideally, the diversion channel should be at a slight incline, allowing gravity to feed the spring. A good rule of thumb is to locate the diversion channel at least 10-15 feet away from the spring to prevent contamination.

Designing the Diversion Channel

The diversion channel should be designed to handle the expected volume of water and prevent erosion. A good starting point is to dig a shallow channel with a depth of 6-8 inches and a width of 12-18 inches. The channel should be slightly sloped to allow gravity to flow the water towards the spring. To prevent erosion, line the channel with rocks or gravel and ensure the soil is stable. A good technique is to use a “swale” design, where the channel is shallow and wide, allowing the water to spread out and infiltrate the soil.

Installing a Check Valve

To maintain a stable water flow and prevent backflow, install a check valve at the end of the diversion channel, near the spring. This will prevent water from flowing back into the channel and allow the spring to recharge consistently. A good option is to use a simple “T” valve, where one side allows water to flow into the spring and the other side allows excess water to flow back into a nearby drainage system. This will help maintain a consistent water flow and prevent erosion in the surrounding area.
