Abstract
This work describes the energy requirements for water supply and sewerage management of Faisalabad urban area and additionally suggests energy management improvements by incorporating grid connected renewable Photo- Voltaic (PV) based power generation. As the ground water in Faisalabad is mostly saline, Water and Sanitation Agency Faisalabad (WASA FSD) brings water from nearby soft water sources and pumps them to consumers within the city. To maintain water supply and sewerage disposal operations, WASA FSD requires to purchase 40k to 50k USD worth of electricity monthly from Faisalabad Electric Supply Company (FESCO) which is financially burdening for WASA. Additionally, as this energy demand is met from Pakistan’s already strained national grid, there is a need to better manage Agency’s energy requirements. In this work, we study utilization of an On-Grid PV solution for renewable power generation to meet the agency’s requirement of are 3.238 ×106 electricity units per month. Such systems can, in principle, eliminate dependency of WASA on the National Grid and additionally provide WASA with an energy efficient and sustainable power generation system with low environmental impact. In this paper, simulate a solar energy system without any energy storage system to determine its feasibility. Here, we present simulation results to estimate successfulness of such a project. Additionally, financial and technical aspects of the project have also been discussed suggesting a payback period less than 7 years.
Highlights
Faisalabad being the third largest city in Pakistan with a population of over 4 million and a thriving industrial sector requires a very elaborate water and sewerage management system. This task has been assigned to a Public authority known as the Water and Sanitation Agency Faisalabad (WASA FSD)
Sewerage management from city’s residential, commercial and industrial sector using disposal stations is managed by WASA FSD
The electricity units produced by the solar energy system of WASA Faisalabad are sold to Faisalabad Electric Supply Company (FESCO) with the help of netmetering technology
Summary
Faisalabad being the third largest city in Pakistan with a population of over 4 million and a thriving industrial sector requires a very elaborate water and sewerage management system. This task has been assigned to a Public authority known as the Water and Sanitation Agency Faisalabad (WASA FSD). Clean drinkable soft water within the city is very scarce and WASA has resorted to using water pumping stations and tube wells to meet the city’s needs. Most of this water is brought using pumping stations from nearby soft water sources around the city.
