Regulations will ultimately require nearly all surface water supplies to be filtered. Together, the water supply professionals, the regulators, and the small communities need to take a closer look at cost‐efficient, low‐surveillance technologies that provide safe, reliable water. Slow sand filtration, one such technology, is experiencing a renaissance of attention. It is an energy‐efficient, lowcost, basic technology that can achieve substantial savings through efficiency of design and simplicity of operation while providing safe water to consumers. However, there is a dark side–inappropriate regulatory requirements and antiquated design criteria.
