It serves a population of approximately 5,924 people, placing it in the small-to-medium agglomeration category. The plant is situated in the East Midlands region, an area characterized by mixed urban and rural landscapes. As a UK wastewater facility, MAREHAY STW operates under the Water Industry Act 1991 and is regulated by the Environment Agency.

The plant's treatment process and capacity details are not publicly available, but it is expected to meet these regulatory requirements to protect local water quality. The treated effluent from MAREHAY STW likely discharges into a local watercourse that feeds into the River Derwent or one of its tributaries. The River Derwent flows southward through Derbyshire, eventually joining the River Trent near Derby. The Trent then flows into the Humber Estuary, which drains into the North Sea. This catchment supports diverse aquatic life and is important for regional biodiversity.

MAREHAY STW discharges into the River Derwent catchment, a tributary of the River Trent. The Trent flows into the Humber Estuary, a major ecological feature that supports migratory fish and bird populations. The local watershed includes the Derbyshire Amber Valley, an area with significant groundwater resources and sensitive aquatic habitats. Protecting water quality in this basin is crucial for maintaining the ecological health of the downstream river system and the Humber Estuary.
