ECONOMIC DESIGN OF PIPELINE USING WATERGEMS SOFTWARE AND CPHEEO GUIDELINES IN THE REJUVENATION OF EXISTING MI/ZP TANKS IN AURAD TALUKA, BIDAR DISTRICT, INDIA

The technical evaluation of the Rejuvenation of Existing MI/ZP tanks in Aurad Taluka demonstrated a sustainable design and hydraulic network efficiency. Hydraulic modelling using WaterGEMS has validated the performance of the entire water distribution network. The observed pipe velocities, ranging from 0.4 to 2.0 m/s, fall within the recommended limits of the Central Public Health and Environmental Engineering Organization (CPHEEO), confirming the design’s adherence to national standards. The design of the Rising Main from the jack well to the Break Pressure Tank (BPT) spanning 15,300 meters with a 1,700 mm diameter, ensures the smooth delivery of water at a flow rate of 4.528 m3/sec and velocity of 2.0 m/s. The system successfully meets the demand and pressure requirements at the BPT. This confirms adequate water volume under necessary pressure conditions. Moreover, the application of economic diameter analysis has resulted in the selection of pipe sizes that are not only hydraulically sound but also cost-effective. The cost comparison carried out for each diameter of pipe and cost effective one is considered for reducing cost of the project. This balance between technical and financial efficiency highlights the project’s well-optimized planning and design approach. In summary, the integration of sustainable water sourcing, technically validated hydraulic design, and cost-effective infrastructure planning positions the project as a model for rejuvenation of MI/ZP tanks systems. It ensures reliable water delivery, energy efficiency, and long-term operational sustainability, ultimately contributing to improved public health and quality of life for the served communities.
