Evaluating Drinking Water Quality Standards and Technologies: A Comparative Analysis of Kenya, China and Germany

Abstract

This comparative review examines drinking water quality regulations, treatment technologies, and compliance practices in Kenya, China, and Germany. It draws on recent peer-reviewed articles, regulatory reports, and policy documents from the three countries to highlight both the challenges and effective strategies in managing drinking water across varying levels of economic development. Access to clean water is essential for public health and sustainable development, yet disparities in infrastructure, regulation, and technological capacity continue to hinder progress in many regions. Germany maintains near-universal access to high-quality drinking water through multi-barrier treatment systems, advanced monitoring technologies, and strong regulatory enforcement. China has made major strides in urban areas through modern technologies and strict regulations, though rural regions still face infrastructural and economic limitations. Kenya, a developing country, grapples with weak enforcement, limited technical capacity, and fragmented monitoring systems, especially in rural areas. The study recommends strengthening Kenya’s regulatory systems, investing in infrastructure and skilled personnel, digitising monitoring, and increasing public involvement. Drawing lessons from China and Germany, the paper emphasises the need for adaptive, well-funded, and inclusive water governance to achieve universal access to safe drinking water.
