Reliability & Quality go hand-in-hand when it comes to water. CPWS is committed to providing safe, quality drinking water to its customers located in the City of Columbia and parts of Maury County.
State and Federal governments are responsbile for setting high standards for water quality. CWS is responsible for producing and supplying drinking water that meets or exceeds these standards. CWS conducts an extensive water quality testing program, and your drinking water is tested literally hundreds of times each year. Water samples from various locations are analyzed each day in the CWS lab or by independent state certified labs. Additional testing is conducted each week for bacterial contamination. Results of these tests and other tests are reported regularly to state authorities. Water quality tests use ultra-sensitive measuring equipment to detect substances as small as one-half part per billion! Results of these tests show that CWS drinking water meets or exceed all state and federal standards.
CWS employees monitor the water system 24 hours a day, 7 days a week to ensure our customers receive reliable, quality drinking water.
