Sandy Bay First Nation New Water Treatment Plant

Sandy Bay First Nation New Water Treatment Plant

Project Summary: Sandy Bay Ojibway First Nation (SBOFN) Reserve No. 283 is located on the south basin of Lake Manitoba in the Westlake Region of Manitoba, 120 km northwest of Winnipeg and 60 km northwest of Portage la Prairie. The reserve is accessed by an all-weather provincial road grid system via PTH 50. SBOFN has a total registered population of 6,781 people. The estimated on reserve population including both registered and unregistered persons is 4,909. The reserve contains 601 residences and 30 FN owned buildings and facilities. The existing treatment system does not comply with applicable guidelines including the ISC, Health Canada, or Manitoba Provincial requirements for surface water treatment. Furthermore, the system requires additional storage capacity to meet future community demands, provide for the fire protection needs, and meet the disinfection requirements for a surface water source. The proposed project includes construction of a new Water Treatment Plant (WTP), installation of a new raw water intake pipe and screen into Lake Manitoba, zebra mussel control system for the raw water intake system, new raw water intake pumphouse and intake line to the WTP, one new remote truckfill, one retrofitted truckfill, new water supply line rom the WTP to the school, and connections to the existing distribution and sewer system for the community. The existing WTP, school pumphouse, and westend pumphouse will be decommissioned. The new truckfill is proposed to be located at the corner of South Boundary road and South Ridge road complete with a reservoir to provide convenience for trucked delivery and reduce traffic in the core area. Whereas the retrofitted truckfill is proposed to be located at the soon to be decommissioned existing WTP, intended to service to the homes in the northern portion of the reserve. Infrastructure: The new WTP will require a new building within the community adjacent the arena, community centre, and school. A new raw water intake and screen into Lake Manitoba will be required. The new raw water supply line will be routed alongside an existing road to the new WTP. It is proposed that the new intake line be placed in the vicinity of the existing intake which is proposed to be capped (to be confirmed at detailed design) and will include a zebra mussel chemical control system and copper fish screen (DFO compliant). Power will be provided through the existing electrical lines with new electrical service provided at the WTP via existing 3-phase service available by the Arena located adjacent to the project site. The existing distribution lines within the community will be incorporated in the project with new connections including: connection of the WTP distribution line to existing, connection to the school and connection to the new truckfill. A connection and line to the existing sewage lagoon via a manhole will be added to discharge of WTP process wastewater. A new truckfill station complete with a reservoir is also proposed.
