We operate reticulated wastewater schemes (or mains sewerage schemes) in many of the urban areas of the District. These schemes carry effluent to the District's wastewater treatment plants.
Properties that lie outside these schemes rely on on-site wastewater treatment. It is vital that on-site wastewater management systems are designed, installed and managed to reflect the nature of the site conditions and constraints associated with the property and dwelling. If they do not, domestic wastewater will not be treated or contained on-site and the discharge will result in adverse effects off-site.
The Wastewater bylaw applies to all users of the wastewater system but has a focus on trade waste and protection of the wastewater system infrastructure.
The bylaw sets out the requirements around connection and discharges to the wastewater system, the extent of public/private responsibilities, the prevention of inflow and infiltration, and working around wastewater reticulation
The flow chart below provides guidance and information on the types of wastewater that trigger the rules of the bylaw.
