The Edgefield County Water & Sewer Authority is still experiencing sporadic discoloration throughout its water system.  Our Water Treatment staff has been sampling our system and has determined that the cause of this discoloration is iron and manganese.  We have consulted with water chemists to adjust levels of chemicals that we use to control iron and manganese to a higher level and have started making those changes immediately.  We are also continuing our flushing of water mains in affected areas.  The Authority is committed to providing safe water to all its customers.

We again apologize for any inconveniences during this time.

Edgefield County Water & Sewer Authority has recently been dealing with discolored water in its water distribution system.  A mechanical malfunction with a surge arrestor at our Water Treatment Plant allowed excessive air to enter our water system.  This air has caused a discoloration of water throughout our system.  This discoloration is due mainly to dissolved manganese and iron in our source water from the Savannah River.  Over time, this manganese and iron deposit on the inside of water mains.  When turbulence in the water main in the form of air or increased water velocity occurs, it can cause these deposits to slough off, discoloring the normally clear water to varying shades of black or brown.  Lab tests have confirmed the discoloration is due to iron and manganese.  Manganese and iron in these quantities are not harmful but can cause discoloration of laundry. 

The Authority has had crews flushing water mains for the last two weeks to alleviate this problem.  This has significantly reduced the issue in most of our system; however, there are still areas that are experiencing problems.  Please do not hesitate to call ECWSA at (803) 637-3011 so we can dispatch a crew to your area to investigate and flush the main.  As a customer, you may also need to run your household plumbing for 10-15 minutes to clear your plumbing of discolored water as well. Also, if you are only seeing discolored water from your hot water plumbing, you may need to flush your water heater to alleviate the problem.

The ECWSA is still experiencing discolored water moving through the system. We have several hydrants in the area flushing to help lessen the spread. If you should experience the discolored water, please contact our office so we can trace where it is going and follow recommendations below. Sorry for any inconveniences this has caused.

The ECWSA would like to update our customers on this developing situation. A mechanical malfunction with a surge arrestor at our Water Treatment Plant allowed excessive air to enter our water system.  This air, along with increased usage over the last few days has caused a discoloration of water throughout our system.  This discoloration is due mainly to dissolved manganese in our source water from the Savannah River. ECWSA has begun extensive, systematic flushing of our water distribution system to help alleviate this issue.  We will be starting on our main distribution lines and working our way out flush the system.  The Authority asks that you still call in with complaints of dirty water so we can pin point areas of flushing.

If you experience discolored water the ECWSA recommends that you minimize the use of your hot water as discolored water could accumulate in your hot water tank and require that you flush the tank after this event has passed. We would also discourage you from washing whites if at all possible to minimize staining. We are sorry for the significant inconvenience this event has and will cause and appreciate your patience as we work to correct this problem. We will post updates as they become available to let customers know what we are doing to remedy the situation.  These updates will be posted on our website,

Once we complete water main flushing for the road you live on, there are a few steps that ECWSA recommends to clear personal service lines.

  • Run cold water using a high flow faucet (such as an outside hose bib or bath tub) for a few minutes. We suggest trying this for no longer than 5 minutes. This will only use a few cents worth of water and should quickly remove the discolored water from your service line and plumbing. 
  •  If the water becomes clear, then briefly flush each of the remaining faucets in your home.
  • You may also want to run one or two washing machine cycles without clothes to clear any discolored water that may be in the lines that feed to the washing machine.

If you notice discolored water while running the hot water, you may need to flush your water heater. If you are unsure how to flush the water heater, you can run hot water in the bath tub for around 10-15 minutes. This will only use a few cents worth of water and should remove the discolored water from the heater tank

Edgefield County Water & Sewer Authority crews will be conducting a physical survey of the sanitary sewer system in the Towns of Edgefield, Johnston and Trenton, along with the area around Pine Ridge golf course beginning in September 2020. Testing will continue through November 2020. This study will involve the opening and entering of manholes in the streets and easements. An important task of the survey will be the “SMOKE TESTING” of the sewer lines to locate breaks and defects in the sewer system. The smoke that you see coming from the vent stacks on houses or holes in the ground is NON-TOXIC, NON-STAINING, LEAVES NO RESIDUE, HAS NO ODOR, WHITE TO GRAY IN COLOR AND CREATES NO FIRE HAZARD.
The smoke should not enter your home unless you have defective plumbing or dried up drain traps. Should the smoke enter your home, open all of your windows and doors to ventilate and reduce inhalation of smoke and contact the office so the crew can be dispatched to your home for investigation. Our smoke testing crew will be pleased to check with you as to where and why the smoke entered your home. In the event of discovering that you have a defect in your internal plumbing you may want/need to consult with your licensed plumber. It is advisable for you to pour water in any drains that are not used regularly. This will help to seal the trap and prevent any sewer gases, odors, or smoke from entering the building.
Some sewer lines and manholes are located on the backyard easement property line. Whenever these lines require investigation, members of the inspection crews will need access to the easements for the sewer lines and manholes. Homeowners do not need to be home and the workmen will not need to enter your home. Photographs are to be made of leaks occurring in the system. The information gained from this study will be used to improve your sewer service and may help reduce costs. Your cooperation is greatly appreciated.
Should you have any questions or need to notify us of anything please call (803) 637-3011.
