Planned Dredging at Lake Howell Beginning in March

Lake Don T. Howell (Coddle Creek Reservoir) includes two raw water intakes, one near the dam along Highway 73 (owned by City of Concord), and another near Highway 3 (owned by City of Kannapolis).
 
The City of Kannapolis intake (near Highway 3) is situated at the upstream end of the reservoir, with a shallower depth overall, and is therefore subject to effects from silt deposition. Per a request from City of Kannapolis staff, with their desire to resume use of their intake soon, WSACC requested bids for dredging in the area surrounding their intake. Bio-nomic Services was the low bidder for this effort, and they anticipate starting work at the reservoir in early March 2023.
 
The work will include removal and dewatering of approximately 4,000 cubic yards of sediment from the area surrounding the intake. Dredging equipment and areas will include a barge, floating pipe, and dewatering and associated work on adjacent land owned by City of Kannapolis and WSACC. This removal of about 4,000 cubic yards of sediment is intended to be sufficient for City of Kannapolis to resume use of their intake reasonably soon.

Final Flow Study of Rocky River Planned for October 31

County Residents May Notice Non-Toxic Red Tint in the River

Concord, NC – On Monday, October 31, Tetra Tech, an environmental contractor for the Water and Sewer Authority of Cabarrus County, will measure flow speed of Rocky River by placing in-stream automatic data loggers and a non-toxic red dye at four locations along the entire Rocky River mainstream.

This measurement is a necessary component of the Authority’s new strategic master plan and will provide data to make informed decisions for the future. It was requested by and approved by the North Carolina Department of Environmental Quality.

Dye placement is planned for Monday, but may be delayed with any significant weekend rainfall. Residents may notice the red tint to the river for few days following the placement of the dye. This scientific study is harmless and there is no cause for concern.

“The red-colored dye used in the Rocky River is different than food dyes. It is formulated as a water tracer and has been used for decades and is approved by the EPA as harmless to people, fish, and plants when diluted at scientifically calculated concentrations, which were employed in this study,” said Hillary Yonce, Professional Hydrologist and Environmental Scientist with Tetra Tech.

The Water and Sewer Authority of Cabarrus County is an independent, incorporated, public body funded by user fees with no taxing authority supporting Cabarrus County. The Authority serves as the primary planning agent for water and sewer facilities, provides wholesale wastewater transportation and treatment for its organizing jurisdictions, and provides reservoir management for some, or all, of its jurisdictions.

Authority Confirms Non-Toxic Red Dye Placed in Rocky River Used for Water Flow Measurement

Concord, NC – On Friday, September 1, Tetra Tech, an environmental contractor for the Water and Sewer Authority of Cabarrus County, placed a non-toxic red dye into four points of Rocky River to measure water speed and flow. This measurement is a necessary component of the Authority’s new strategic master plan. It was requested by and approved by the North Carolina Department of Environmental Quality.

Residents may have noticed the red tint to the river over the course of the weekend, but Sunday’s heavy rainfall has expedited the dissipation of the red coloring.

“To measure time of travel (flow speed) of Rocky River, we placed in-stream automatic data loggers and placed a non-toxic red dye at four locations along the entire Rocky River mainstream,” said Hillary Yonce, Professional Hydrologist and Environmental Scientist with Tetra Tech. “Our team began retrieving the data loggers on Tuesday, September 6, and will complete this process soon. This scientific study is harmless and there is no cause for concern.”

The red-colored dye used in the Rocky River is different than food dyes. It is formulated as a water tracer and has been used for decades and is approved by the EPA as harmless to people, fish, and plants when diluted at scientifically calculated concentrations, which were employed in this study. The dye used in this study carries a National Sanitation Foundation “Standard 60 Certification for use in or around potable water sources”.

Tetra Tech anticipates conducting one additional dye study this fall, however the exact date will be determined based on weather and streamflow conditions.

Don’t Clog with FOG

Fats, Oils and Grease—known collectively as FOG—represent the most serious enemy of our sewer lines. Did you know cooking grease, fats, and oils being poured down drains are a major cause of residential sanitary sewer spills resulting in unsightly, smelly, and costly messes? When FOG is dumped down the drain, it forms large, thick grease balls that clog the pipes. Fats, oil and grease will clog sewer lines (the same way bad cholesterol can clog heart arteries), causing sewage back-ups and flooding. Sewage back ups can damage personal and public property. Drain excess grease or cooking oil into a can, cool and toss. Wipe any leftover grease from the pan with a paper towel and throw the paper towel away. Controlling FOG discharges will help WSACC prevent blockages and sewer lines from overflowing, which cause public health and water quality problems. To report a sanitary sewer overflow, please contact WSACC at 704-788-4164.

Prescription Pills: What’s in Your Water?

Let’s do an experiment. Grab a glass of water, pour some salt into it, mix it up and wait for the salt to dissolve. Now un-dissolve and remove it.

It’s not possible, right? Exactly how do you un-dissolve salt from water once it’s in there? Well, this is the exact problem that wastewater and water treatment plants are having when it comes to removing dissolved prescriptions and over-the counter medications from wastewater and water supplies. These plants are not designed to remove medicines that have been poured down the sink or flushed down the toilet. As a result, they pass through treatment systems and enter rivers and lakes, and ultimately straight to your tap. Which means your next dose of water could be dosed with something else.

So how do we prevent this? Spread the word. Never flush or pour old prescriptions down toilets or sinks—dispose of them in your household trash. To avoid accidental medication poisoning, keep pets and young children out of the bottles by dissolving the pills in water and mixing it with kitty litter or used coffee grounds. Then place it in a secure, lidded container in your trash. Taking these steps helps keep your pipes clear and our water safe!

It’s a Toilet,
Not a Trash Can

Never flush the following items (or put down the garbage disposal or drain). Toss them in the trash instead.

  • Baby/Facial/Cleaning Wipes
  • Tampons
  • Sanitary Napkins
  • Medication
  • Hair
  • Dental Floss
  • Cotton Swabs/Ball
  • Bandages
  • Rags and Towels
  • Rubber Items (like latex gloves)
  • Fat, Cooking Oil, Grease
  • Clothing Labels
  • Candy/Food Wrappers
  • Syringes
  • Cigarette Butts
  • Disposable Toilet Brushes
  • Kitty Litter
  • Aquarium Gravel
  • Plastic Items
  • Diapers
  • Fruit Stickers
  • Paper Towels

Only flush the three P’s… pee, poo, and (toilet) paper.
