Resilience of critical water infrastructure systems across the UK

The United Kingdom (UK) benefits from an efficient and reliable water and sewerage infrastructure. It is providing a continuous very high-quality supply of piped water for almost all households and connection to a mains sewerage system. The critical water infrastructure's development path can be traced to the beginnings of the early nineteenth century. It has been shaped by the industrial revolution, urbanisation and increasing demand driven by economic development and high environmental standards. The roles of government, privatisation for water utilities and companies, regulators and other authorities continue to present current and future challenges across the UK. This paper describes critical supply infrastructure systems across the UK, its development and effect of the climate change, urbanisation and population growth in future demand and supply. Further, the applicability of reusing wastewater in supporting a bio-circular economy, smart and intelligent water network technologies to improve the reliability and longevity of physical water infrastructure can be improved by data analytics and customer led changes for the sustainable water supply solutions in meeting these demands
