This Guidebook provides hundreds of techniques, sample codes/policies, and community examples that explain how to reduce the water footprint of new development. Each chapter in the guidebook provides water efficiency policy options in a different planning stage: comprehensive plans, zoning code, subdivision regulations, site-plan regulations, development agreements, non-zoning incentives, and more. The Guidebook is targeted to land use planning professionals but written in an accessible manner for water professionals and other interested parties as well.

The Plumbing Efficiency Research Coalition (PERC)  announced the publication of the Phase 2.1 supplemental report on the drainline transport of solid waste in building drains. The Phase 2.1 report details the findings from additional work the Coalition was able to conduct using remaining funds carried over from the PERC 2.0 research study. The Drainline Transport of Solid Waste in Buildings – Phase 2.0 was originally released in September of 2015. The PERC 2.1 findings appear as a new appendix to the PERC 2.0 report.

The Phase 2.1 supplemental report focuses on two previously unaddressed areas of study — the implications surrounding dual flush toilet discharge patterns, comparing results to single volume flush toilets of comparable flush volume, and on the impact of drainline slope deviations on the transport of solid waste.

This May 2009 issue paper examines the range of potential water savings measures and practices, as well as their application in specific industries. In addition, we present case studies of water agencies and businesses across California to offer insights into how some of these programs have been implemented, the costs and benefits of the programs, and some of the barriers and challenges that water agencies and businesses face. Lastly, we offer recommendations for what water agencies, businesses and government can do to promote smart water efficiency practices and save water in the CII sector.
