 Brave Blue World Documentary Film Premiers in Los Angeles

Water Environment Federation Proud to be Production Partner

ALEXANDRIA, Va. – A new feature-length documentary film titled Brave Blue World premiered in Los Angeles on December 16 and examines how new technologies and innovations can create a sustainable water future.

The Water Environment Federation (WEF) is a production partner for Brave Blue World and will use the film to raise public awareness about the solutions to water challenges.

“It is important to convey a sense of hope and spirit of optimism for water and that is why WEF is thrilled to be a production partner for Brave Blue World,” said Walt Marlowe, WEF Executive Director. “By showing a path to a sustainable water future Brave Blue World can help us to influence leaders, increase resources, change policies, and improve stewardship of water.”

The film is narrated by Liam Neeson and includes interviews with a variety of water experts, as well as high-profile advocates Matt Damon and Jaden Smith. It features compelling stories, beautiful scenery, and examples from across five continents to show novel ways of tackling water problems. The film explores developments in areas such as water reuse, nutrient recovery, energy generation, decentralized treatment, and the digitization of water.

“From a NASA research center, where we learned how water is recycled in space, and a textile plant in India that is meeting 90 percent of its water needs from recycled water, to the world’s largest algae-powered wastewater treatment plant in Spain and a children’s home in Kenya, where 50 litres of water a day is being provided from humidity in the air, we heard many inspiring stories,” said Executive Producer Paul O’Callaghan, who is also founder of BlueTech Research. “We’re tremendously excited to be able to share these with a wider audience and move water up the global agenda as an issue we can solve in our lifetime.”

Brave Blue World also includes a segment with Tom Kunetz, Past President of WEF, at the world’s largest nutrient recovery facility, the Stickney Water Reclamation Plant operated by the Metropolitan Water District of Greater Chicago.

WEF and its Member Associations plan to hold numerous screenings of the film across the country in 2020.

Joint Municipal Water & Sewer Commission Receives Bond Rating Upgrade

December 12, 2019

Contact: Donna Peeler, Intergovernmental Relations, Joint Municipal Water & Sewer Commission, 803-785-3212

In a move that restructures debt and provides funding for new capital projects, the Joint Municipal Water and Sewer Commission is issuing a new series of revenue bonds in the amount of $44 million in December 2019.  By refunding and defeasing outstanding water and sewer revenue bonds, the Commission will realize a savings of approximately $2.18 million and the return of approximately $566,000 in reserves.  Additionally, the new revenue bonds will provide approximately $20 million for new capital projects.   

As a result of strong financial planning and performance, the rating agencies have assigned an upgrade to the Commission’s bond rating. 

Moody's Investors Service has upgraded Joint Municipal Water and Sewer Commission, South Carolina's (JMWSC) revenue rating to Aa2 from Aa3. 

Moody’s report stated that the “Upgrade to Aa2 reflects JMWSC's long trend of strong financial performance, very healthy liquidity and demonstrated willingness to utilize its unlimited rate setting authority.”  

S&P Global Ratings raised its long-term rating on the Joint Municipal Water and Sewer Commission, S.C.'s water and sewer system revenue debt to 'AA+' from 'AA.'  

S&P’s report stated that “The upgrade is based on the Commission's improved financial profile, as evidenced by roughly doubling its liquidity position over the past five fiscal years to extremely strong levels and maintaining robust all-in debt service coverage (DSC) which we believe to be sustainable given its established track record of raising utility rates annually to support its capital improvement program (CIP).” 

General Manager, Jay Nicholson says “Strong leadership and support from our commissioners and the management of our financial model have provided a favorable path for efficient performance.  This is affirmation of our commitment to be good stewards of the community’s resources.”

Water Quality  

Many of our customers have noticed the earthy smell and taste to your tap water recently.

This is an issue with all water providers drawing water from Lake Murray. While this is not uncommon for surface water systems across the country, it has never been this unpleasant locally.

We have been working with treatment plant personnel to implement immediate and long-term strategies to address this issue once and for all.  We hope to see improved results soon. 

Please be assured this is an aesthetic nuisance only and not a water safety concern. We apologize for the inconvenience and frustration this is causing the communities we serve.  We appreciate your patience and understanding while we work to resolve the issue.

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.
