Water and Sewer Utilities
The City of Duncan is committed to maintaining and upgrading water, sewer and storm sewer infrastructure. The primary purpose of the City of Duncan’s water system is to provide clean, safe drinking water. To ensure sustainability of the system, the City of Duncan undertakes a number of initiatives towards water conservation, such as the ongoing Water Metering Program.
The City’s water sources are four deep wells and two reservoirs for water distribution which are situated near the Cowichan River and which extract water from a sub-river aquifer. This aquifer is considered to be an “un-confined” aquifer that is regenerated by water from the river and adjacent watershed being filtered by layers of pervious soils.
Water and sewer services include the operations and maintenance of the City’s water and sewer systems. The City’s water distribution system covers approximately 5 square kilometers and services over 15,000 people extending into portions of the Municipality of North Cowichan, the Cowichan Valley Regional District Electoral areas “D” and “E”, and Cowichan Tribes lands. The City maintains a separate system of underground pipes to collect sewer and waste water for treatment at the Joint Utilities Board (JUB) Lagoons that are jointly owned with the Municipality of North Cowichan. The City’s proportional costs of maintaining the JUB Lagoons is included in the sewer service charges.

Toilet Rebate Program
Save water with the Low Flush Toilet Rebate Program! Many homes are equipped with older toilets that require 13 or more litres per flush. New high efficiency toilets require only 4.8 litres per flush and dual flush toilets use a combination of 3 and 6 litres.
By replacing your old toilet, you could use up to one-third less water! That could save more than 200 litres per day or 70,000 litres per year.
The City is offering a lifetime maximum of two (2) rebates per residential or commercial unit. Replacing toilets using 13 litres or more, with a CSA-approved new high efficiency model, will earn you a rebate. The rebate is $50 for a high efficiency (4.8 litres) or dual flush model (3/6 litres). Applicants must provide a receipt dated after January 1, 2010 for the purchase of a CSA-approved low flush toilet, provide photographic proof of installation of a low flush or dual flush toilet and that the old toilet has been removed and destroyed.
