McGill Associates Knoxville Assists with Water Improvements Through East TN

Water quality is essential to a community’s health and well-being. Across east Tennessee, McGill Associates has been busy working with numerous municipalities on important water infrastructure projects. Such projects benefit local communities and lay the foundation for future development and beneficial growth opportunities. Our staff of engineers and support personnel use their extensive water and wastewater knowledge to engage and understand the needs of local communities, working to implement solutions that are well thought out, creative, and sustainable.

City of Jefferson City

McGill Associates recently completed upgrades at the Jefferson City Water Treatment Plant, where capacity was increased from 5.0 to 7.5 MGD. Our engineers provided design, funding assistance, bidding services, and construction administration services for the project, which was funded by a combination of a USDA-Rural Development loan and grant, an SRF loan, and an EPA-STAG grant.

City of Elizabethton

In Elizabethton, McGill Associates designed upgrades to the existing water treatment facility at Valley Forge to add membrane micro-filtration and residuals management facilities to this 1.5 MGD water treatment facility.

At the Lions Field Pump Station in Elizabethton, we designed rehabilitation improvements and capacity upgrades. This project included the replacement of aging pumps and motors with new, high efficiency 1,200 GPM dry-pit submersible pumps with variable frequency drives. The project also eliminated the floor-mounted pump motors and the elongated drive shafts of the old pumps to create safer operation and maintenance conditions for the City.

The replacement of an existing biosolids dewatering system at the Elizabethton Wastewater Treatment Plant included the installation of two new centrifuges, progressing cavity sludge feed pumps, polymer feed system, and control system to replace an aging plate and frame press dewatering system.

Erwin Utilities

The Erwin Railroad Water Treatment Plant had experienced some bacteriological and perchloroethylene contamination and was in need of treatment upgrades. Our staff provided funding assistance, design engineering, bidding, and construction phase services for the installation of a 900 gallon per minute pressure sand and activated carbon filters, new chemical feed system, a new filter building, and instrumentation and controls.

City of Blaine

McGill Associates assisted the City of Blaine with the design of a new wastewater collection system and a 105,000 gallon per day wastewater treatment plant. After a complete alternatives analysis, the chosen method to dispose of the treated wastewater was to land apply the effluent, utilizing drip irrigation technology. This method involved the slow rate dispersal of the wastewater through a network of drip irrigation lines that are placed approximately 8-10 inches under the soil.

The City of Blaine had never operated a utility, and McGill Associates assisted the City in all aspects of defining this utility, including operational procedures, ordinances, rates, and funding for a new wastewater system.
