DESIGN OF A WATER STORAGE AND TRANSMISSION SYSTEM FOR WASTEWATER REUSE IN COVENANT UNIVERSITY

This research is focused at designing of water storage facilities of size 875,000 litres (750,000 litres for underground water storage, and 125,000 Litres for elevated steel tank) of treated wastewater and its transmission system for the storage and re-use of treated wastewater. The project is aimed to structurally design water storage facilities and its transmission system from the reservoir to the overhead tank for the re-use of treated wastewater in Covenant University. The design works was divided into two major parts namely: Transmission system design, and water storage facility Design. Transmission design was divided into two, which are the field activities, and the software activities. Magellan eXplorist 350H North America GPS (Global Positioning System) was used for the field activities, it was used to determine coordinates (Longitudinal and Latitudinal) of various location of points in the university campus, its key usage was to determine the lowest and the highest elevation points on campus, the highest elevated coordinate point was located in between the male postgraduate hall of residence and the postgraduate cafeteria, and the lowest elevated point was at the existing wetland which is directly opposite Daniel’s hall in the campus. The software used for transmission system is WaterCAD, which was used to design the flow path network from the lowest elevation to the highest elevation point. The water storage facility design software used are Staad pro., Orion, and AutoCAD. Staad pro. Was used to analyse and design for the underground water tank, and the elevated steel water tank, while Orion software was used for concrete design and it was used to detail the underground water tank. The result gotten from all the design software were imported to AutoCAD software for editing, scaling, and proper output result.
