Drinking Water System
The Town of Niagara-on-the-Lake owns and operates two separate drinking water distribution systems which are the Niagara-on-the-Lake drinking water system (Niagara-on-the-Lake DWS) and the Bevan Heights drinking water system (Bevan Heights DWS). The Town maintains responsibility for water distribution only; the facilities for water treatment and storage are owned and managed by the Niagara Region. The two drinking water systems distribute treated drinking water within a service area of approximately 12,600 Ha. The service area is bounded by Lake Ontario, the Niagara River, the City of Niagara Falls and the City of St. Catharines.

The Niagara-on-the-Lake system receives treated water from the Niagara Region’s Decew Falls Water Treatment Plant in St. Catharines and the Niagara Falls Water Treatment Plant, both of which are regionally owned and operated. The Niagara-on-the-Lake system conveys water to approximately 15,000 residents through an estimated 200 km of Town-owned watermains.

Drinking Water Licensing
In the findings of the Walkerton Inquiry, Justice O’Connor recommended that municipal drinking water systems owners obtain a licence to operate their systems and incorporate quality management into their operations. To meet this recommendation, the Ministry of Environment (MOE) developed the Municipal Drinking Water Licensing Program, under the Safe Drinking Water Act, 2002. All municipalities in Ontario that supply drinking water must have a Licence for their system. The Town of Niagara-on-the-Lake has valid licenses for both of it's drinking water systems.

In order to obtain a Licence, municipalities are required to have:
• A Drinking Water Works Permit
• An Operational Plan
• Accreditation of the Operating Authority (
third party audit of the Drinking Water Quality Management System)
• A Financial Plan

The Town's operating authority has full scope-entire DWQMS accreditation. Accreditation Certificate 2018-2021

Town of Niagara-on-the-Lake’s Drinking Water Quality Management System (DWQMS)
Implementation of the Drinking Water Quality Management System (DWQMS) is part of the new Municipal Drinking Water Licensing Program. A Quality Management System (QMS) consists of a set of policies, procedures and objectives that direct and control an organization with respect to quality. These policies, procedures and objectives are documented in the Town’s Operational Plan. A QMS helps to identify and prioritize risks, improves communication and team work, and provides procedures to enhance consistency and reduce errors.

Operational Plan
The purpose of the Operational Plan is to document the Town of Niagara-on-the-Lake’s Drinking Water Quality Management System (policies, procedures and objectives) to help ensure that safe drinking water is supplied to all of its customers. The operational plan applies to all drinking water related operations at the Town of Niagara-on-the-Lake and Bevan Heights drinking water systems.
Copies of the Operational Plan are accessible to the public. Hard copies are available at the Town Administration Building (1593 Four Mile Creek Road) or at the Public Works Building (3 Lorraine Street) in Virgil.
