Project Scope; Expand the District of Tofino's Ginnard Creek Water Reservoir to increase drinking water supply to Tofino. Construction consisted of excavating Ginnard Creek and two unnamed tributaries to increase the existing water reservoir volume from 3,650 m3 to 44,388 m3. Scope of project included impacts associated with excavation of the existing pond which included machinery access points to the project site. The total project value: was $1,235,000 with the Provincial contribution: of $823,333.
This project improved the water quality issues by expanding an existing watershed storage as well as modifying the Sharp Road Booster Pump Station, and adding ultra-filtration membrane technology.
Nestled below the coastal mountains of Mount Colnet and Lone Cone mountain on Meares Island, Tofino's water source receives and abundance of rain water which is filtered through the surrounding watershed. This process allows natural impurities in the rainwater to be filtered out before it reaches the Sharp Creek and Ginnard Creek reservoirs.
The Meares Island water then transfers to the Bay Street Pump House, the Ahkmahksis Water Treatment Plant through submerged pipelines under Browning Passage to Tofino, where it is treated, stored and delivered to the residents and businesses.
The District's mandate was to provide and sustain an adequate supply of good clean water into the future. This is made possible through the development and use of programs that include long range planning, system operation, system maintenance and capital works.
Although Tofino had experienced water restrictions and shortages in the past, significant improvements related to Sharp Creek’s increased reservoir capacity, and the construction of the five million (5,000,000) gallon reservoir on Ginnard Creek and the Ahkmahksis Water Treatment Plant together have helped to improve, integrate, and homogenize the overall water supply system. Additionally, the recently upgraded Inter-zonal Pump House is greatly beneficial in balancing the District’s water storage capacity by moving water from low pressure systems to high pressure systems.
Thanks to cameras positioned over the dams and reservoirs, the District staff is able to continually observe the systems and monitor the amount of water flowing over the weirs. Site inspections are regularly performed to confirm the actual water flows and levels of all District water sources. The District of Tofino’s water supply is continuing to meet user demands; even throughout the busy summer seasons.
