Investing in the Future 

Press Release

Lexington County’s Water Future Sits on Counts Ferry Road 

Commission’s future water treatment plant to be built on 47-acre site 

January 11, 2019 | News Release

Contact: Donna Peeler, Joint Municipal Water & Sewer Commission, 803.785.3212  

The Joint Municipal Water and Sewer Commission took a significant step today in planning for the future water needs of Lexington County by purchasing 47 acres on Lake Murray. The purchase is an investment in serving the county, where population growth and the need for redundancy in the water system mean additional treatment capacity will be necessary.

“A rapidly growing region means we will have the need to increase our water supply. We’re looking 20 to 30 years out now, so that we stay on top of planning for new infrastructure that ensures the best value for our customers,” said Commission Chairman Steve MacDougall.

Several factors led to the decision to purchase the property. “The location on Lake Murray will easily connect into the existing and planned capital projects for the distribution system and will ensure the same, reliable water supply our customers expect,” said the Commission’s General Manager, Jay Nicholson. “The site was specifically identified to secure future water supply for the county. When built, the plant’s location will allow for service continuity in the region.” 

The Commission is planning to meet the future needs of Lexington County which is anticipated to double in population over the next twenty years. The Commission currently distributes water from the City of West Columbia’s treatment plant located on Old Cherokee Road. This plant will remain the primary source of water for the Commission.  The new treatment plant will provide needed redundancy to the water system, making the water supply even safer and more resilient in the future.

“Lexington County has grown since the Commission was created 25 years ago,” said Tem Miles, Mayor Pro-Tem of West Columbia. “Having additional treatment capacity at that location will be a benefit and help support the communities we serve.”

The Commission is planning for expansion of treatment capacity now, so design and construction timelines can be phased and implemented with as little financial impact to customers as possible. The land purchase is the first step in building a new treatment plant, but construction isn’t planned for many years to come. 


The Joint Municipal Water and Sewer Commission is a regional partnership of 11 members throughout Lexington County. Since 1993 we’ve developed a reliable system that provides safe drinking water with a focus on excellent service and affordable rates.

Our mission is to provide exceptional service to communities through responsible stewardship of resources.

Water Quality 

Some of you may have noticed an earthy smell or taste to your tap water recently.  

The treatment plant operators have increased carbon feed and made other process adjustments to help eliminate these odors.

This seems to be due to Lake Murray water temps reaching a peak for this season, combined with slightly lower water levels at the lake. Please be assured this is an aesthetic nuisance only and not a water safety issue. Our crews are responding to each call to confirm chlorine levels are adequate as well as flushing when/where appropriate. 

Other plants drawing water from Lake Murray are experiencing similar issues. 

We apologize for any inconvenience this causes while we work to resolve the issue. Your patience and understanding is appreciated.

Public Notice October 2016 

Public Notice - No Violation


In July 2016, the Joint Municipal Water & Sewer Commission (JMWSC) sent public notice of an exceedance in the drinking water standard related to a disinfection byproduct (DBP) called haloacetic acids (HAA5). Around that same time, the City of West Columbia began making changes in the treatment process to reduce DBP formation. We have been monitoring these changes and are pleased to report that the South Carolina Department of Health and Environmental Control (DHEC) third quarter compliance sample results confirm our own findings that DBP levels have been significantly reduced. The samples show no violation of the drinking water standard for DBPs.

The JMWSC purchases water that has been treated by the City of West Columbia at the City’s Lake Murray Water Treatment Plant and delivers that treated water to our customers. As our water supplier, the City of West Columbia has responsibility for treatment of the water we deliver, and for minimizing DBP formation during the treatment process. Although the JMWSC does not have full control over the treatment processes and operations at the City of West Columbia treatment plant, we work closely with DHEC and the City of West Columbia to monitor water quality.

As water professionals, we take seriously our role in providing safe drinking water, understanding and interpreting state and federal drinking water regulations, and keeping the public informed while ensuring we do not create undue concern. We will continue to keep the public updated with relevant information and provide additional notice if additional measures become necessary. Thank you for your continued support of our critical mission to deliver safe drinking water. Should you have questions, please do not hesitate to contact us at 803-359-8373 or customerservice@lcjmwsc.com.
