Evaluating Wastewater Management On the Outer Banks

(RALEIGH, NORTH CAROLINA – May 24, 2010) – Currituck County, North Carolina, has selected Hazen and Sawyer to develop a comprehensive wastewater master plan for the Outer Banks portion of the County. The goal of the Master Plan is to develop a regional solution to wastewater management and extend central sewer service to areas that are currently unsewered. An integrated approach to water management that considers wastewater management, water supply, and stormwater management will be developed for the Outer Banks.

To date, wastewater treatment and disposal on the Outer Banks has been handled by a number of privately-operated wastewater treatment plants, along with individual septic systems. Environmental and water quality concerns are mounting over the large number of septic systems as well as for some existing wastewater treatment plants which suffer from inadequate maintenance and/or outdated treatment technology.

Due to the sensitive ecosystem of the Outer Banks, the State of North Carolina prohibits direct discharge of treated effluent into the Currituck Sound or Atlantic Ocean. A primary challenge of this project will be developing innovative non-discharge methods for treated effluent disposal that protect the surrounding environment and meet the projected capacity needs while considering the realities of high property values on the Outer Banks.

In developing the master plan, Hazen and Sawyer will examine alternatives for adopting a regional approach to wastewater management on the Outer Banks and improving treatment performance and increasing capacity. The plan will outline capital improvements necessary to accommodate the long-term capacity needs of planned growth patterns, ensuring the long-term health of wastewater management throughout the County.

Since our founding in 1951, Hazen and Sawyer has focused on two things: providing safe drinking water and controlling water pollution. Our range of services encompasses the planning, design, and construction management of water and wastewater-related projects – from clean water treatment, storage, and distribution to wastewater and stormwater collection, treatment, and reuse.
