Resources for Drinking Water Utilities

U.S. EPA: Protecting Our Water, Our Future

As part of our mission to protect human health and the environment, EPA is happy to share the results of our research into treatment methods and technologies for safe drinking water and sanitation. We've assembled a collection of resources on this page that we hope will be useful to drinking water utilities across the globe.

Arsenic in Drinking Water Treatment Resources

Arsenic treatment technologyFollowing the announcement of a new standard for arsenic in drinking water, EPA invested $20 million in research, development, and testing of cost-effective treatment technologies for arsenic. As part of this investment, EPA also funded the development of technical assistance and training materials for drinking water system operators.

Software Tools for Water Utilities

EPANET is software that models water distribution piping systems. EPANET is public domain software that may be freely copied and distributed. It is a Windows 95/98/NT/XP program. EPANET performs extended period simulation of the water movement and quality behavior within pressurized pipe networks.

CANARY

CANARY is software developed by EPA to enhances a water system’s ability to detect when there has been intentional or unintentional contamination. The Canary software can help detect a wide variety of chemical and biological contaminants, including pesticides, metals, and pathogens. Once contamination is detected quickly, a water utility can issue a “Do Not Drink” order to prevent customers from ingesting the water.

Storm Water Management Model (SWMM) Screenshot of SWMM software.

SWMM is a dynamic hydrology-hydraulic water quality simulation model. It is used for single event or long-term (continuous) simulation of runoff quantity and quality from primarily urban areas. The runoff component operates on a collection of sub catchment areas that receive precipitation and generate runoff and pollutant loads. The routing portion transports this runoff through a system of pipes, channels, storage/treatment devices, pumps, and regulators.

Other Resources

EPA's Clusters Program works to bring together regional networks of water industry organizations - including businesses, universities, government agencies, and support groups. These networks can be a resource for bringing new water technologies to market and solving regional water problems.

Additionally, EPA assembled a broad collection of resources from a variety of additional EPA programs for the Water Environment Federation's Technical Exposition and Conference in 2014. Some of these resources may also prove useful to World Water Forum participants.
