Annual Water Supply & Demand Assessment

The Annual Water Shortage Assessment (see below) projects a supply shortage for the CCSD through June 30, 2023. The average monthly reduction in demand necessary to close this gap is 12%.  The table below provides projected monthly supply and demand volumes, along with the projected benefit from water shortage response actions to be implemented by CCSD staff. The table will be updated monthly to reflect actual water supply and demand volumes as they become known.

Annual Water Loss Audits

The CCSD is required to complete annual water loss audits which are then validated by a third-party to ensure accurate analysis of all metrics. Water loss is unavoidable in the production and distribution process, but it can be minimized to the best extent possible. Annual audits measure the CCSD's progress in implementing best practices to reduce avoidable losses.
