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.
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.
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.
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.
