Information Regarding Recent News Coverage of West Columbia 


Information Regarding Recent News Coverage of West Columbia Water System


There is no greater responsibility we have than delivering safe drinking water to our community, and we are vigilant in protecting the public health of our neighbors and families that we serve. 

The Joint Municipal Water and Sewer Commission (JMWSC) delivers water that has been treated by the City of West Columbia at its Lake Murray Water Treatment Plant.  Although we do not have direct authority over the processes and operations at the treatment plant, we work with SC Department of Health and Environmental Control (DHEC) and the City to monitor water quality.   Our understanding from the SCDHEC statement is that there is no imminent cause for concern.   We encourage the City to continue pursuing the investments necessary to correct the issues noted by DHEC in its annual review of the plant operations.

Public safety is our top priority, and there are measures of water quality assurance that JMWSC takes every day as a regular course of operation in our own system.  Although these are standard processes for any water system, they are especially vital to us at JMWSC as we recognize that we are the direct connection between our customers and their drinking water.  Our staff employ a variety of important steps on a regular schedule to keep us informed of the quality of water we supply to your tap.  This includes collecting water samples for water quality testing from locations across our system, opening fire hydrants at various locations across our system to “flush” the lines and keep fresh water flowing into the system, and routine storage tank maintenance.  

We are proud to deliver quality drinking water to you and your family, not only because it is our responsibility, but because we also rely on it for our own families and friends.  Monitoring and communicating with the City and DHEC are important in ensuring the safety of the service we provide.  You have our continued pledge to stay engaged and alert.   If you ever have any questions or concerns about your drinking water, we encourage you to contact us.  We are here to serve you.

Is Lead in my drinking water? 

Our sampling indicates no lead detected

Under the EPA's Lead and Copper Rule, JMWSC is required to sample regularly for lead and copper levels at service locations deemed to potentially have lead and copper in their structural plumbing.  

Our sampling indicates that no lead has been detected.  Because of recent changes at the source water plant, and in coordination with SCDHEC, JMWSC is increasing the frequency by which we sample for lead and copper to confirm those levels remain safe. 

For more information please contact us at (803) 359-8373.

JMWSC Supporting the Midlands 


Many area municipalities and utilities have been dealing with the aftermath of the recent flood.  The Commission was very fortunate to experience only minor operational issues. 

The Commission cares about the community and wanted to help.  The Commission delivered approximately 15 ½ pallets of bottled water to various communities and organizations (1120 cases = nearly 27k bottles).  

Some of the organizations JMWSC helped: Harvest Hope, Bible Way Church, St. John Baptist (Hopkins), Town of Eastover, Trenholm Baptist, Christ Central Ministries, and Williamsburg County.

6,912 bottles were donated and delivered by JMWSC staff Mike Coffey & Wesley Robertson to a central warehouse in Kingstree, SC
