21st Century Water Storage Recommendations Apr 1, 2015 Policy Documents In April 2015, ACWA released “21st Century Water Storage: Recommendations for California’s Future” detailing the need for water storage project investments to meet the state’s water needs. The recommendations, contained in a policy document approved by the ACWA Board of Directors in early 2015, helped inform and guide the California Water Commission as it develops its process for allocating $2.7 billion in funding for water storage projects under Proposition 1. The recommendations were developed by an ACWA Board-appointed task force with representatives from every region of the state.
