Domestic, community, and municipal wastewater

Public Consultations

Domestic wastewater is water from toilets, as well as greywater (water from kitchens, baths, washing machines, and certain household appliances other than a toilet). In the case of community or municipal sewage systems, industrial waste may be included. It is vital that this water be properly managed in order to protect public health, preserve our waterways, and provide a clean environment for future generations.

This section contains information concerning domestic wastewater management for community, municipal, and individual projects generating more than 3,240 liters of domestic wastewater every day.
