The purpose of this project was to design a functional pump station and protective steel shelter near Secret Lake in Okanagan Similkameen, BC, aimed at supplying drinkable water to a nearby remote community. This comprehensive project involved the creation of a pipe network, pump installation, and logistical planning for material and equipment transportation led by ________________________and ______________________. The project also utilized SAP2000 and AutoCAD for structural modeling and layout design, respectively. The project addressed the technical requirements of both steel and concrete structures to ensure durability and efficiency. Using the City of Kelowna Design Standards, an inside pipe diameter of 200mm (ductile iron) was determined from the required flow of 70L/s. Utilizing the ground profile view from Google Earth Pro, the pump head from this system came to 75.3m. The pump required for this application was determined to be MPC-E 4 CRE 95-2 running for 45 years for 6 hours a day bringing the total cost for the pump aspect to be $845,225.57. The pipe support consists of an HSS 127x6.4 with a saddle support having a spacing of 5.7m. Utilizing the National Building Code of Canada (2020) and the Handbook of Steel Construction (11th edition) for steel design, along with the CSA A23.3-04: Design of Concrete Structures for Concrete Specifications, the project delivered a framework capable of enduring the necessary loads. The steel structure, characterized by purlins (C200x17), side girts (C180x15), end wall rafters (W200x42), front girts (C180x15), columns (W200x52), and middle frames (W200x52), was optimized for strength and weight, ensuring a resilient shelter for the pump station. The total cost for all steel members came to $135,675 including cladding. The concrete components, including the pump pad (200mm thick), base slab (400mm thick), and strip footing foundation (250mm thick), were calculated to support the operational needs of the pump station, using 25 MPa concrete and 350 MPa rebar, confirming the infrastructure’s stability. The concrete cover for the strip footing foundation and base slab came to 75mm while the pump pad concrete cover came to 40mm. The strip footing had a base of 1m by 1m with a total depth under the soil of 850mm. The size of the rebar calculated came to 15M for all temperature reinforcement, main reinforcement in the strip footing and pump pad as well as 25M for main reinforcement in the base slab. Logistical planning addressed the challenges of the project’s remote location, detailing the clearing of a 219m pathway (5m wide) for construction and maintenance access, thereby aligning with the project's environmental considerations and operational requirements. Results from SAP2000 simulations affirmed the structural integrity under various loading conditions, showcasing minimal deflections and stress levels within acceptable limits, thus highlighting the effectiveness of the selected materials and design approaches. The project culminated in a series of recommendations aimed at ensuring code compliance, validating structural calculations, and proposing further investigations for cost analysis and soil inspection, ensuring the project’s adaptability and safety. Additionally, a detailed cost analysis provided insight into the financial implications of the steel structure, cladding, and logistical operations, facilitating informed decision-making for future implementations.
