Small Drinking Water Systems
and Capacity Development
Note: EPA no longer updates this information, but it may be useful as a reference or resource.
This program addresses issues affecting drinking water systems serving populations of less than 3,300. Its main focus is on capacity development, which refers to the technical, financial, and managerial capacity of a system to provide safe drinking water. The program also provides information about treatment technology options for small systems.
EPA is working to identify additional affordable arsenic treatment technologies to enable small systems to comply with the revised arsenic maximum contaminant level. Promising technologies are being pilot-tested in the field. A list of small-system compliance treatment technologies is available.
