Update: Long Creek Wastewater Spill

April 24, 2018 – Charlotte Water (CLTWater) crews responded to a broken wastewater pipe near Oakdale Road on April 23rd. Crews estimate approximately 15.4 million gallons reached Long Creek, part of the Catawba River Watershed. Drinking water supplies are not impacted by this spill.

At approximately 5:30 p.m. Monday, CLTWater received information from Mecklenburg County regarding a sewer odor and fish kill. CLTWater crews discovered a broken 30-inch wastewater pipe at the confluence of McIntyre Creek and Long Creek. It appears recent storms caused trees to fall and erosion of the stream bank up to 50 feet in some places. The wastewater pipe, undermined by the debris, heavy flows and erosion, fell into Long Creek under its own weight.

Ongoing storms and rushing water made containment of the spill challenging for crews. By 10:45 a.m. Tuesday the spill was stopped and crews began cleanup and pumping operations so that no further wastewater will spill.

CLTWater will begin the process of reinforcing the pumping operation with heavy duty bypass lines and pumps. Contractors are also onsite designing the repair. The timeline for repairs is not yet known.

North and South Carolina officials have been notified as well as downstream residents and businesses. Mecklenburg County officials have announced a no swim advisory for this area downstream of Long Creek until further notice.

Charlotte Water Responds to Wastewater Spill in Long Creek

April 24, 2018 – Charlotte Water (CLTWater) crews responded to a broken wastewater pipe near Oakdale Road, at the confluence of McIntyre Creek and Long Creek on April 23rd. Crews are working to estimate gallons that may have reached Long Creek, part of the Catawba River Watershed.

30″ Wastewater Pipe at the bank of Long Creek

A wastewater pipe was 50 feet from the creek bank, a fallen tee eroded the creek bank and caused the 30″ wastewater pipe to break, possibly due to Monday evening’s storm.

Charlotte Water is currently notifying downstream residents, mobilizing crews and resources to control the spill, and make repairs.

This spill does not affect drinking water.

Updates will follow with details as they are available.

Lee Dukes Water Treatment Plant Turns 20

Twenty years ago North Mecklenburg County looked a lot different than it does today. Talk of toll roads and Whole Foods markets were not even on the radar. But Charlotte Water knew this region of the county was growing and with that came an increase in the need for water. At the time, all the water for the county was supplied by water from Mountain Island Lake, treated at Franklin and Vest and pumped up to residents in Northern Mecklenburg. With the addition of a new intake on Lake Norman at Blythe Landing and the treatment plant across the street, Charlotte Water could better serve the residents of north Mecklenburg with a closer water source.

Originally Lee Dukes, or North Mecklenburg Water Treatment Plant as it was once called, was built to be a community center in addition to a treatment plant. Unlike most treatment plants, the lobby area was designed to look aesthetically pleasing and shows off mosaics made by local children and artists and houses the extensive collection of woodcarvings made by Lee Dukes himself. Unfortunately due to increasing need for security after 9/11, community events in the facility had to be minimized. Though Blue Planet was not in the original plans, due to an EPA grant the environmental learning facility was built within Lee Dukes plant and served residents for ten years before being closed.

The plant opening was delayed a year due to difficulties installing the 60” diameter concrete pipe under Highway 73, this pipe connected the pump station at the lake to the treatment plant.

Three plant operators that were part of the inaugural staff on that day in 1998 still work at Charlotte Water, with two of them still working at the same plant. The science behind water treatment hasn’t changed much in 20 years and except for some updated office technology, the plant hasn’t changed much either.

Currently, Lee Dukes treats about 18 million gallons a day but the land purchased by Charlotte Water in the mid 90’s has room for much more equipment that would increase the capacity of the plant significantly if needed. This treatment plant is in it for the long haul and will continue to play an integral role in the growth of Huntersville, Cornelius, and Davidson.

 

Cold Weather and Water Main Breaks

Charlotte Water encourages all customers to protect plumbing from freezing weather. Did you know that the water in the 4,300 miles of water mains doesn’t freeze? But, when temperatures are well below twenty degrees (20o) outside, soils may shift causing an increase in water pipe repairs.

Here are a few other reasons why pipes may break:

  • Construction crews hitting mains during groundbreaking, Call 811 before you dig to locate the pipes
  • Ground movement
  • Corrosive soil conditions
  • Weaknesses where two pipes are joined together, that start as slow leaks and can lead to big problems
  • Weight of soil constantly pushing down on pipes
  • Aging infrastructure, this is a national problem and will require huge amounts of money and political will to fix
  • Weak seals.
  • Temperature changes that can cause the soil to expand and contract, putting stress on pipes.
  • Normal aging
  • Surprisingly, even water has corrosive properties and can break down the inside of the pipe over a long period of time

Unfortunately, since the breaks occur underground, in most cases we can only speculate as to how exactly the pipe broke.

Regardless of the reason, we know that:

  • Crews are repairing pipes including service lines, hydrants, and water mains in 100+ locations on an average week and 4,000+ locations annually.
  • During freezing temperatures, Charlotte Water experiences a slight increase in emergency repairs.
  • Public streets may be salted near water leaks to reduce slippery conditions.
  • Lanes may remain closed until temperatures are warm enough to make asphalt for repaving.
  • Charlotte Water prioritizes leaks and water main breaks
  • Before repairs can be made, Charlotte Water calls 8-1-1 (NC-One Call) to have underground gas and other utilities marked (spray painted).
  • To repair drinking water pipes, Charlotte Water temporarily shuts off water to the broken pipe.
    • Customers may experience air in their pipes or cloudy, discolored water after service resumes.
    • Customers should run the cold water for up-to-10 minutes.
    • If conditions do not improve, please call 311 or 704-336-7600.
  • Charlotte Water proactively rehabilitates or replaces pipes that are nearing the end of their life cycle.
  • Charlotte Water staff work 24/7 to provide drinking water and wastewater services to Mecklenburg County and beyond. Call 311 or 704-336-7600 if you are experiencing a water emergency.

Life in 1927 vs. 2017

No one can dispute that a lot has changed in 90 years. One thing that hasn’t changed is Charlotte Water’s commitment to safeguarding public health and protecting our waterways.  Our twin wastewater treatment plants, Sugar Creek and Irwin Creek are celebrating their 90th birthday this year (they were built in 1927). While these two plants have expanded and advanced in technology throughout the last 90 years, they continue to be an award-winning treatment plant that serves the Charlotte community 24/7.

Let’s compare the world in 1927 to now.

90 Years of Safeguarding Public Health

What do Rome, the Indus Valley civilizations and Charlotte have in common? They were all cities that thrived due to the installation of water and wastewater infrastructure. Without clean water to drink and sanitation systems, people fell prey to disease.

Before Irwin and Sugar Creek wastewater treatment plants (WWTP) were built, Charlotte residents dumped raw sewage directly into nearby creeks and streams. These practices were the root cause of outbreaks of cholera, typhoid, infectious hepatitis, and polio. In 1924, Sugar Creek Wastewater treatment plant was built on Little Sugar Creek and began partial treatment of wastewater. In 1927, Sugar Creek WWTP was expanded and Irwin Creek WWTP was built, and both were the first modern-style plants in the state. They used the highly-effective activated sludge treatment process to remove nutrients and organic materials from the wastewater before it was put back into the creeks and streams.

This technology allowed for an increased quality of life for the residents of Charlotte, less polluted waterways and supported the consistent economic and population growth of the Charlotte region.

Many sectors of the economy are reliant upon water, and any disruption of water/wastewater services can cost businesses a significant amount of revenue. Since 1927, Sugar and Irwin WWTP’s have been treating wastewater 24 hours a day, 7 days a week, and due to many plant expansions are now able to treat up to 20 and 15 million gallons, respectfully, of wastewater per day.
