Delhi WWTF is an operational wastewater treatment facility located in Delhi, Ontario, Canada. The plant serves a population of approximately 3,178 residents in the community of Delhi, part of Norfolk County in Southwestern Ontario. As a municipal treatment plant, it plays a key role in managing wastewater for this small agglomeration. The plant operates under Ontario's regulatory framework for wastewater systems, which aligns with the Canada-wide approach to wastewater effluent standards. For a facility of this scale, typical treatment includes primary and secondary processes to meet provincial discharge requirements. The designed capacity of 1.00 million liters per day indicates the plant's capacity to handle the community's wastewater flow. The treated effluent from Delhi WWTF is discharged into the local watershed, which ultimately drains into the Lake Erie basin via the Big Creek and Grand River systems. Lake Erie is a vital freshwater resource supporting diverse aquatic life and providing drinking water for millions. The plant's operations contribute to protecting the water quality of these downstream water bodies.

Delhi WWTF discharges into the Big Creek watershed, which flows into the Grand River and eventually reaches Lake Erie. Lake Erie is the shallowest and most biologically productive of the Great Lakes, supporting a rich ecosystem of fish, birds, and aquatic plants. The plant's treatment helps protect this sensitive freshwater resource from nutrient pollution and pathogens, which is critical for maintaining water quality and ecological health in the region.
