Water Master Plan Update

December 2020 – Spring 2021

LAWSS Grid Reinforcement and Twinning (2021 Addendum)
 LAWSS Master Plan (2021)

Project Description

The Lambton Area Water Supply System (LAWSS) has initiated a study to review and update its 2015 LAWSS Master Plan.  The LAWSS is owned by its member municipalities and operated by the Ontario Clean Water Agency (OCWA) on behalf of the LAWSS Joint Board of Management.  LAWSS currently supplies water to over 100,000 customers within three Supply Systems that service the City of Sarnia, Village of Point Edward, Township of St. Clair, Municipality of Lambton Shores (Forest), Town of Plympton-Wyoming, Village of Watford/Township of Warwick and Municipality of Brooke-Alvinston.

The Master Plan study will review the 2015 water servicing strategy and identify capital project upgrades (e.g. new watermains, pumping or storage facilities) needed to provide sustainable municipal water and accommodate future growth in LAWSS member municipalities over the next 20 years and beyond.
