What is the distance recommended between public water supply lines and lined evaporation beds?

The recommended distance between public water supply lines and lined evaporation beds is 10 feet. This specific distance helps to ensure that there is a sufficient buffer zone between the potentially contaminated water in the evaporation beds and the potable water supply lines. The separation is crucial for protecting public health by minimizing the risk of contamination from seepage or water movement that could compromise the quality of the drinking water. This guideline is based on best practices and regulations designed to prevent cross-contamination and to maintain the integrity of the public water supply.
