At the test facility in Lemoore, California, non-potable water sources are used, not municipal drinking water. The Wave Basin is designed for this, using sophisticated onsite filtration technology to treat water so that it is suitable for human contact. After treatment, the water quality is comparable to that of a swimming pool.

The current intent is to utilize the same “non-potable” water sources used predominantly by golf courses, consisting of shallow well water and imported water from the Colorado River.
