San Diego plans to boost the city’s already thriving biotech and craft beer industries by reducing their costs for sewer and water service, which are typically high because those businesses are water-dependent. The city plans to create California’s first “capacity bank” for water and sewer, which would allow breweries and biotech firms to cheaply buy excess capacity from former factories that have transitioned to other commercial uses. A companion proposal would geographically expand and soften the qualifying requirements for the city’s “guaranteed water” program, which ensures local firms access to water during droughts or other kinds of shortages.
