The Greater Moncton Wastewater Commission (GMWC) was created by an order-in-council in 1983 based on a model outlined in a consultant’s report and in consultation with the three municipalities and the Government of New Brunswick.

The GMWC was then mandated to implement the Master Plan as laid out in the study. From 1983 to 1995, the GMWC oversaw the construction of a 35-km network of collector sewers intercepting more than 80 untreated outfalls; the construction of a major pumping station along with eight smaller ones and the implementation of an advanced primary treatment system. Over the subsequent decade it proceeded with the implementation of a long-term sustainable biosolids management program with a new innovative composting system.

In 2014, the Commission renamed itself the Greater Moncton Wastewater Commission (GMWC). The GMWC has been proven as an effective tri-community model and has demonstrated co-operation and the ability and efficiency to deliver results. Its assets are well managed, well maintained and fully paid for. Under the direction of its General Manager, the operations and maintenance team continues to meet current expectations and aims to anticipate future needs.

The federal government’s new wastewater systems effluent regulations (WSER-2012) were enacted under the Fisheries Act. This new legislation now guides the effluent compliance requirements for wastewater treatment facilities and requires that the GMWC meet these new requirements by 2020.

The WWTF Upgrade and Modernization Project will be completed in August 2021 upgrading from primary chemically enhanced treatment to secondary biological BNR treatment to meet federal effluent regulations by the end of 2020.
