Clean drinking water and reliable sanitary services are cornerstones of successful cities that usually go unnoticed until service is disrupted. Manhattan prides itself on achieving high standards in wastewater treatment and in water treatment distribution. The City is in the process of updating its Water and Sewer Master Plans, which will have key growth-related infrastructure recommendations to address over the next 10–20 years. In addition, the City completed a Water and Wastewater Facilities Plan in 2019, which provides guidance for the water supply and wastewater treatment systems for the next 15 years.
