CSCE Dinner Presentation: Ending Boil Water Advisories in Enoch Cree Nation
Date: February 20, 2020
Time: 5:30 PM to 8:30 PM
On January 9, 2019 Enoch Cree Nation celebrated the grand opening of their new $14 million upgraded water system, ending years of periodic boil water advisories by providing the community with a safe, reliable, long-term supply of water. The project includes the following components:
- A connection to the EPCOR water supply system;
- 3.3 km of supply pipeline;
- A 4,600 m3 potable water storage reservoir;
- A pumphouse with truckfill, distribution, and fire pumps;
- A 103.5 DC kW/ 90.8 AC kW solar field;
- Watermain looping in the Village Core; and
- Newly swabbed distribution system piping.
The upgrades have sufficient capacity to accommodate growth in the community up to 3,900 people. Construction of the project also provided significant economic benefit to the community. Approximately 18,000 person hours of employment and training for community members and 1,700 hours of rented community-owned construction equipment were utilized by the contractor, which equated to approximately 10% of the capital cost of the project.
The project took over ten years to advance from the planning phase to the start of construction and involved considerable interjurisdictional cooperation between Enoch Cree Nation, the City of Edmonton, EPCOR, the provincial government, and the federal government. The project was uniquely challenging from a technical perspective and included safely undertaking construction in an area that was used for munitions testing in WWII, removal and replacement of large quantities of surface debris and contaminated soils, and partially powering the pumphouse by electricity produced by solar panels onsite.
