Liquid waste, wastewater, and sewage are terms for "used" water and the wastes that it carries. Basically, they are terms for what is flushed down the toilet or washed down the drain. Wastewater can also include rain water, groundwater or snow melt (inflow and infiltration) that make their way into sanitary wastewater pipes.

How is wastewater treated in the Regional District of Nanaimo?
The majority of wastewater in the RDN is treated by public wastewater (sewer) systems or privately-owned onsite systems (such as septic systems). A small number of properties are authorized by Island Health (VIHA) to use pump and haul services. Typically, pump and haul services are used by properties with failing onsite systems or by those who cannot connect to public wastewater systems and are unable to obtain Ministry of Health approval for a conventional septic disposal system.
How do I know if I'm on sewer?
If you benefit from sewer services, your property tax and/or utility bill will include a charge for this service. Most people living within Nanaimo, Lantzville, Parksville, Qualicum Beach and French Creek receive sewer services. However, some properties within municipal boundaries have a private onsite (septic) system and some people in the Electoral Areas have sewer.
