The facility is situated in the southeast of England, an area with a temperate maritime climate and a mix of urban and rural landscapes. As a small-to-medium agglomeration, the plant plays a key role in managing local wastewater from the town and surrounding areas. The plant's designed capacity is 1.00 (likely in megaliters per day or equivalent units). Under the UK's implementation of the EU Urban Waste Water Treatment Directive (UWWTD), treatment plants serving populations between 2,000 and 10,000 are generally required to provide secondary treatment.

The treated wastewater from Billericay STW is discharged into local watercourses that ultimately drain into the River Thames estuary and the North Sea. The plant helps protect the ecological health of these water bodies by reducing nutrient and pollutant loads. The downstream environment supports diverse aquatic life and is important for migratory fish and bird species.

The plant discharges into local streams that flow into the River Crouch or the River Thames, both of which drain into the Thames Estuary and the North Sea. The estuary is a ecologically sensitive area supporting diverse aquatic life, including important fish nurseries and migratory bird populations. The plant's treatment helps maintain water quality in this dynamic coastal environment.
