Consolidated Utility District Annual Reports
After the turn of each fiscal year, Consolidated Utility District (CUD) creates an annual report that speaks to the accomplishments of our various departments and the growth of our distribution network and customer base. See the sidebar for links to the PDFs of each report that was mailed to our ratepayers.
This year’s report carries a variety of data points that speak to our growth and accomplishments during the past year. It’s also important for our ratepayers to know the following seven essential truths about CUD:
- We exist to serve our ratepayers.
- We are funded by tap fees and monthly bills. We receive no tax dollars.
- CUD is nonprofit and considered part of Rutherford County government.
- State law allowed for the creation of CUD.
- CUD is subject to all Tennessee state government meeting laws.
- We operate by EPA and state conservation regulations.

• CUD published its annual Water Quality Report at www.cudrc.com/water-quality/water-quality-reports/ and mailed copies in our printed billing statements. Highlights include:
• Per state and federal law, CUD tests hundreds of water samples at our water treatment plant and in the distribution system. Tap water is analyzed even more than bottled water.
• For 14 different kinds of contaminants – including lead – CUD had zero violations. Your water has a clean bill of health, according to the Environmental Protection Agency and the Tennessee Department of Environment and Conservation.
• CUD uses chlorine at a rate of 2 to 2.5 parts per million in its daily treatment process. Chlorination is the most popular method of water disinfection worldwide, and it is required by Tennessee state law. Chlorine is also considered effective in eliminating COVID-19.
Water Treatment Plant
• To support the continuing growth of Rutherford County, the K. Thomas Hutchinson Water Treatment Plant completed a $15.5 million expansion in 2020. The upgrade enables the plant to deliver up to 32 million gallons of water per day.
• The plant operates at a zero discharge. The facility sends no materials back to Stones River or any wastewater plant in the area.
• In 2020, the plant deployed a machine called the FlowCam Cyano to screen for bacteria which can potentially become toxic. The FlowCam uses a red laser and image recognition software to separate cyanobacteria from other algae in sample water. This helps CUD to eliminate bacteria and preserve water quality.
• The plant averaged 12.9 million gallons per day, and the highest monthly total for production was June 2021 when the plant produced 460.441 million gallons.
Infrastructure/Capital Improvement Plan
During our fiscal year, CUD spent just over $26.3 million to operate the water distribution system. That number includes the operation of our water treatment plant, consumables, and the costs of equipment. CUD typically spends $10-$12 million each year to upgrade and expand water infrastructure. The following are the largest upgrade efforts the utility is currently managing.
• South Almaville Loop – Shores Road: $3,389,000 – Replaces outdated, undersized water mains with new lines for better flow and pressure with lower maintenance costs
• Highway 231 North Water Main Replacement: $2,363,072 – Replaces outdated, undersized water mains with new lines for better flow and pressure with lower maintenance costs
• U.S. Army Corps of Engineers Storage Fee: $2,083,090 – Provides additional water supply capacity to the water treatment plant to support customer growth
• Rocky Fork Road to Tank: $1,925,590 – Installs larger, longer-lasting pipes for better flow and pressure with lower maintenance costs
• Walnut Grove Water Main: $1,767,808 – Installs larger, longer-lasting pipes for better flow and pressure with lower maintenance costs
• Rocky Fork Pump Station: $1,611,500 – Replaces a pump station for better pressure zone efficiencies in conjunction with water main replacements
• DMA Stations: $830,000 – Improves monitoring of flows in the water distribution system to locate leaks before they become major problems
• Asbury Lane and Burnt Knob Road: $716,842 – Installs larger, longer-lasting pipes that deliver better flow and pressure with lower maintenance costs
• East Lyons Road and Valley View Road Water Main Extensions: $613,129 – Extends water mains in areas where water service was not available and replaces valves that are not functioning properly
• Triple Crown Farms Service Line Replacements: $230,685 – Installs new pipes and adds check valves to fire hydrants for better protection from reverse flow that could contaminate water mains
As of June, myCUD had more than 4,000 downloads among our ratepayers. As a reminder, myCUD is available for iPhone and Android on the iPhone App Store and the Google Play Store. myCUD provides a number of customer-friendly functions including 24/7 account access, billing history, and one-click contact with Customer Service or CUD’s Facebook page.
CUD uses a layered cybersecurity approach. Before data can be brought into CUD’s network, it must travel through two layers of protection. Once data is inside CUD’s protected network, we have additional security through our email provider, as well as our end points (servers, desktops, laptops, and mobile devices).
STEP (Septic Tank Effluent Pump) Systems
• 1,161 STEP tank installations
• 442 flow tests conducted on fire hydrants
• 268 building code reviews
Water availability service requests:
• 56 commercial lots
• 993 multi-family lots
• 7,371 single family lots
• 1,122 plans reviewed and plats signed
• 355 service orders completed
• Because of the limestone in Rutherford County soils, water does not drain easily. However, CUD can place a STEP (Septic Tank Effluent Pump) field on those soils, which provides the foundation for water service and allows establishment of many of the homes and subdivisions in Rutherford County.
• Beginning in March 2021, CUD began repair and replacement of STEP riser lids throughout the county. By the end of the Fiscal Year, CUD had completed this work in seven subdivisions.
• During a typical month, our Customer Service team manages 650 to 750 online service orders, along with roughly 200 new tap purchases.
• The number of customer accounts has seen steady growth. In 2018-19, the total was just under 57,000. In 2019-2020, we served more than 59,000. In 2020-2021, CUD served more than 62,000.

Our response to COVID-19
• CUD uses chlorine in its daily treatment processes. Chlorine is highly effective in removing or inactivating viruses that are even more resistant than COVID-19.
• Our typical daily range of chlorine is 2 – 2.5 parts per million, which eliminates viruses.
• The COVID-19 virus has not been detected in drinking water.
• Conventional filtration methods used by water utilities either remove or inactivate the COVID-19 virus.
• CUD tests at least 120 samples of water each month in compliance with state and federal law. Tap water is more regulated than bottled water.
Expansion of Water Treatment Plant
• The newly expanded water treatment plant delivers a capacity of up to 32 million gallons of water per day.
• Twelve new filters are now in service. Each can handle 1.5 million gallons of water flow per day.
• The plant’s new pipe gallery measures 320 feet in length and contains all piping for the filters.
• The new backwash basin will handle a maximum of 600,000 gallons twice each day.
• Four tanks inside the plant each hold 9,600 gallons of bleach used for disinfection. The plant’s generator can produce up to 20 gallons of bleach per minute.
• During fiscal year 2019-2020, the plant’s highest flow total month was September 2019 (487 million gallons, a 10.7 percent increase over the same month previous year).
• The plant’s expansion cost $15.5 million overall. Construction had no effect on the plant’s budget, aside from expenses related to maintenance. The expansion has been accounted for in each year’s Capital Improvement Plan.
• In 2019, CUD signed a $1.3 million contract with Itron Inc., an energy and water resource management company, to improve metering capabilities for the county’s water distribution system. This means CUD will also be able to gather data from our office without deploying a vehicle.
• During our fiscal year, CUD spent over $32 million to manage the water distribution system. That number includes the operation of our water treatment plant, salaries and wages, consumables, depreciation, and the costs of meters and other equipment.
