- Water Quality & Wastewater Planning
- AECOM Implementation
Water quality in the Town of Orleans and the rest of Cape Cod has been impacted by excessive nitrogen from multiple sources, including septic systems. Excess nitrogen is over-fertilizing ponds, lakes, and bays. This nitrogen pollution causes algal blooms, loss of habitat for aquatic organisms, poor aesthetics, and economic loss.
To address these concerns and comply with the Clean Water Act, the Town worked with the public and prepared and amended a Comprehensive Wastewater Management Plan. This plan was developed in accordance with the regional Cape Cod 208 Water Quality Plan, which has been approved by both the United States Environmental Protection Agency (US EPA) and the Massachusetts Department of Environmental Protection (MassDEP).
The Town has contracted with AECOM since 2015 to implement the Amended Comprehensive Wastewater Management Plan (ACWMP), which calls for traditional sewers and central wastewater treatment for 2 areas: the Downtown Area and the Meetinghouse Pond Area. Also included are provisions for the use of non-traditional technologies including Permeable Reactive Barriers (PRBs) and shellfish propagation to control nitrogen.

In addition to the full text of the plan, this page includes summaries of comments and key issues raised by residents, and appendices with technical memoranda on individual components of the plan.
See agreements between the Town and AECOM and a preliminary project schedule.
Included on this page are a financial model user guide, technical memoranda, and financial model updates.
In addition to traditional engineering tasks, AECOM is responsible for the design and implementation of demonstration projects exploring several complementary non-traditional options for nitrogen removal, including floating constructed wetlands, aquaculture, and permeable reactive barriers (PRBs).
See presentations given at Board of Selectmen meetings, the Orleans Water Quality Advisory Panel, and by AECOM on a variety of topics relating to wastewater management in the Town of Orleans.
Traditional wastewater engineering and planning services provided by AECOM are focused on conventional wastewater treatment with sewerage infrastructure for conveyance from the Downtown and Meetinghouse Pond Areas, effluent disposal, and the decommissioning of the Tri-Town treatment facility.
