Georgia Treatment Plant Gets an Upgrade

The Heard County Water Authority serves more than 380 connections in and around Franklin, Ga. With a growing population, Heard County was beginning to exceed the capacity of the existing wastewater treatment plant.

Outdated Equipment

Protecting the Everglades

For 85 years, the city of Boca Raton maintained contaminant levels well below federal wastewater treatment discharge standards, protecting aquifer recharge sites and the Florida Everglades from contamination. With growing populations, demand exceeded the capacity of the treatment plant and threatened its ability to maintain a high level of treatment. To continue the high level of service, the city decided to expand their treatment plant.

Environmental Challenges

Retrofitting Traveling Bridge Filters

Glendale Heights Wastewater Treatment Plant discharges treated water to the East Branch of the DuPage River in Illinois. Local discharge requirements state that the total suspended solids (TSS) discharging from the plant must be 5 mg/L or less. To remove TSS and meet this standard, Glen­dale Heights employed traveling bridge filters for tertiary treatment. Frequent problems with these filters included: bridge derailment, sand migration, inconsistency during high flows and permanent biological fouling.

100% Reuse

The Emerald Coast Utilities Authority (ECUA) manages water and wastewater treatment for Pensacola, Fla., and surrounding areas. The 19-acre Main Street Wastewater Treatment Plant had been in operation since the 1970s and began to require many upgrades.

Located near the beach off of Pensacola Bay, the Main Street Wastewater Treat­ment Plant was hit by Hurricane Ivan in 2005. When the hurricane struck, it knocked out power to the Main Street Plant for three full days. Some areas of downtown Pensacola were flooded with a combination of storm water, storm surge, and raw sewage.
