The Environmental Services Department administers services including Solid Waste Management, Liquid Waste Management, Fort Fraser Water and Sewer Works, Invasive Plant Control and is also actively engaged in developing the Regional District's Corporate Energy and Emissions Plan.

Solid waste management includes the operation and management of the Regional District's landfill and transfer station facilities to ensure that the handling and ultimate disposal of the region's waste is compliant with environmental standards set by the Ministry of Environment. Solid waste management also includes promoting waste reduction, recycling and composting.

Liquid waste management primarily involves the operation and management of septage receiving facilities which provides sewage disposal for Regional District residents with private sewage collection and treatment systems.

Fort Fraser water and sewer works are operated by the Environmental Services Department and the Fort Fraser Local Commission. The community's water and sewer systems are covered under permits issues by Northern Health and the Ministry of Environment respectively.

Invasive plant control and public education services are conducted through a joint effort with the Regional District acting in partnership with the Northwest Invasive Plant Council.
