The California Urban Water Conservation Council published a series of Potential Best Management Practice (PBMP) Research Reports, beginning in August, 2004 and continuing for 26 reports until the final one in March, 2015. A wide variety of topics were examined, principally for the purpose of determining whether these water efficiency measures might be likely to achieve cost-effective water savings and would thus be a worthy investment for California water suppliers. The reports are archived on the California Water Efficiency Partnership website: https://calwep.org/potential-best-management-practices/
