Tender Details

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.
