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.
