Petaluma’s Recycled Water Quality In 2009, the City of
Petaluma will begin producing recycled water through
advanced treatment, filtering and UV-disinfection. The
water will receive the highest level of treatment as
defined by the State of California (referred to as Title
22); this level of treatment allows for unrestricted
reuse in virtually all recycled water applications. To
ensure a consistent level of quality, which meets or
exceeds its intended uses, the City’s recycled water
undergoes routine testing. The treatment process mimics
the natural water cycle, only faster.
