The City of Marco Island operated a wastewater treatment facility comprised of three parallel treatment units. The existing wastewater treatment facility is bound by various commercial and utilities sites with little available land for new structures. A real estate boom and extensive sewering program resulted in an increased demand for utilities services, including the need for adequate wastewater treatment. The City was faced with the question of either constructing a new larger treatment facility off the island, demolish their adjacent water treatment facilities to accommodate wastewater expansion, or find alternate ways to increase the treatment capacity without increasing the footprint. By 2025 a rated treatment capacity of 5.0 million gallons per day (MGD) would be required. A CDM study concluded that a conversion of the existing contact stabilization plant to a Modified Ludzack-Ettinger (MLE) Process combined with the use of membrane bioreactors (MBRs) would provide the most cost effective solution.
