Population growth and urbanisation are estimated to increase the demand for water and sanitation services by 40% in only 15 years. Globally, approximately 80 percent of wastewater is discharged to the environment untreated, a crucial area of emissions reduction. Utilities can anticipate the need to expand service levels to ensure adequate water supply and sanitation services, while investing in low-carbon urban water services that include energy efficiency and GHG reduction technologies to prevent water insecurity. Those include the reduction of water losses, increased energy efficiency, improved wastewater treatment, conversion from waste to energy and the reuse of nutrients. What are the key challenges and how can these be overcome?
