EBMUD recycled water serves East Bay industrial and irrigation customers; Berkeley sites using recycled water must comply with State Water Board Title 22 cross-connection and signage requirements.
Recycled water in the Berkeley region is produced by EBMUD treatment plants and distributed primarily to large landscape, industrial, and dual-plumbed commercial customers. State Title 22 of the California Code of Regulations governs allowed uses, requiring purple-pipe identification, backflow prevention, signage stating do not drink, and operator certification for sites using disinfected tertiary recycled water. UC Berkeley and several West Berkeley industrial sites are recycled-water customers. Residential dual-plumbed retrofits remain rare and require Building and Safety plan check plus EBMUD service approval before activation.
Cross-connection failures can trigger immediate shutoff, mandatory remediation, and State Water Board enforcement; fines for serious public-health violations may exceed $5,000 per day.
