Centex Homes is developing the historic Glen Riddle Farm into a planned resort community, including 500 single family residential units, 150 multi-family units, a marina, and two 18-hole golf courses. Because there were no centralized municipal water or wastewater systems in the area, Centex Homes needed to construct water and wastewater treatment facilities to service the new development.

In a modified design-build effort, GMB designed 200,000 gallon per day (GPD) drinking water treatment and advanced wastewater treatment plants to reclaim water for irrigation on the golf courses. The $10 million project also includes an elevated water storage tank and a treated wastewater storage lagoon.

The wastewater treatment facility utilizes the Zenon process with hollow-fiber membranes providing ultra-filtration. This produces a very high quality effluent with total nitrogen levels of less that 5 mg/l.

Because of this high quality effluent, buffer zones were reduced for the spray irrigation areas. The use of spray irrigation allows for the recharge of groundwater in a sustainable design feature that is beneficial to the environment and future generations. Furthermore, this approach avoids a point source discharge into shallow coastal bays. The small footprint allows for the entire facility, including the laboratory, to be housed in a single barn-type building.

Adding to the complexity of the project was a highly visible site location for the water and wastewater treatment plants. In order to blend with the existing structures on the property, the design incorporated barns, a 70’ silo, and a greenhouse to maintain the farm-style character.

SCADA controls were incorporated into the project allowing Worcester County to remotely monitor the facility operations from their office in Ocean Pines. The completed project was transferred to the County for operation and ownership.

GMB recently received a Merit Award from the American Council of Engineering Companies of Maryland (ACEC/MD) for the design of the Glen Riddle Water and Wastewater Treatment Plants. Due to the innovation in both engineering and architectural disciplines, the Riddle project was one of the top three in the competition.
