The Water Security Agency is undertaking a critical infrastructure upgrade at the Moosomin Dam, located 12 kilometers south of the Town of Moosomin, Saskatchewan, on Pipestone Creek. Constructed in 1954 by the Prairie Farm Rehabilitation Administration, the dam’s original 17 relief wells, installed in 1955, are now at end of life and composed of aging materials including helcore, transite, no-corrode, and plywood. These wells are being replaced with five new stainless steel pressure relief wells and two additional stainless steel monitoring wells, designed to effectively manage pore water pressures within the dam’s main embankment and foundation, thereby enhancing overall structural stability and controlling the phreatic surface. The project scope includes excavation, installation of a grass swale and half-pipe drainage system, site grading to improve overland water flow, topsoil restoration, and landscaping using certified regional grass seed. The existing 16 relief wells will be decommissioned, with the exception of Well #7, which was previously destroyed and is unlocatable. The Water Security Agency, a Treasury Board Crown corporation governed by The Water Security Agency Act of Saskatchewan, holds responsibility for provincial water management, including dam safety and infrastructure integrity. This procurement, identified as solicitation 2026-27OE-0018, was posted on July 16, 2026, with responses due by August 4, 2026. The work is to be performed at the dam site in Saskatchewan, and all inquiries should be directed to Lee Peters, M.Eng., P.Eng, PMP, whose contact information is provided through the agency’s tender portal. The project reflects a proactive approach to maintaining the long-term safety and functionality of a key provincial water management asset.

Full Description

Show more
Moosomin Dam is located 12 kilometres south of the Town of Moosomin, SK on Pipestone Creek. The dam was constructed in 1954 by the Prairie Farm Rehabilitation Administration (PFRA). A series of 17 relief wells were drilled in the toe of the dam in 1955. The relief well materials of construction vary, and include the use of helcore, transite, no-corrode, and plywood piping. The relief well piping is end of life and requires replacement. WSA intends to install new, modern stainless steel relief wells to reduce pore water pressures through the main embankment dam & foundation of the Moosomin Dam. This will better manage the phreatic surface throughout the dam and embankment, improving the stability of the main embankment dam and foundation. This project includes: Site grubbing Installation of five (5) stainless steel pressure relief wells. Installation of two (2) stainless steel monitoring wells. The construction of the monitoring wells is typical of the pressure relief wells. Well development, testing and well commissioning. Excavation and construction of a grass swale and “half pipe” drainage system for the new relief wells. Decommissioning the existing 16 pressure relief wells. Existing Relief Well #7 (RW7) was previously destroyed and cannot be located. Site grading to provide improved overland water drainage to the project area. Topsoil and landscaping with certified grass seed mix appropriate to the area and environment.
WSA is a Treasury Board Crown corporation within the meaning of The Crown Corporations Act, 1993 (Saskatchewan) that is governed by The Water Security Agency Act (Saskatchewan). WSA is responsible for water management in the Province of Saskatchewan, which includes managing the province’s water supply, protecting water quality, ensuring safe drinking water and the treatment of wastewater, reducing flood and drought damage, protecting aquatic habitat, and managing dams and related supply channels.
