Water Supply Network in Rajshahi City Corporation: Water Quality, Regeneration Effect and Pump Performance

Abstract

Urban water supply systems are currently facing considerable challenges posed by rapid population growth and the constraints of limited resources. Across many urban areas, pumping stations are tasked with providing drinking water; however, the quality of this water often falls short of the rigorous standards set by Bangladesh’s Drinking Water Standards (BDS) and the World Health Organization (WHO). This situation is alarming, as water quality can have dire implications for public health. The efficiency of numerous pumping facilities is significantly lower than the optimal benchmarks established in laboratory tests. As a result, city residents frequently face inadequate access to safe drinking water, a critical resource for daily living. The present study focuses on the performance evaluation of pumping sites within the Rajshahi City Corporation (RCC). This study aims to uncover specific issues that hinder the effective operation of these pumping stations and to propose viable solutions. The analysis investigates essential parameters, including static water levels, the conditions of aquifers, and the impacts of drawdown—each factor playing a pivotal role in the overall performance of water supply systems. The investigation reveals that many pumps fall short of established laboratory standards, with significant seasonal fluctuations in groundwater levels and the effects of drawdown being prominent factors contributing to this inefficiency. By addressing these critical issues, the study seeks to pave the way for sustainable water management practices that ensure equitable access to safe drinking water for all residents, ultimately improving the quality of life in resource constrained urban areas.
