The U.S. EPA has designed and constructed a distribution system simulator (DSS) to evaluate factors which influence water quality within water distribution systems.

Six individual 25 meter lengths of 15 cm diameter ductile iron pipe are arranged into loop configurations.

Each loop is configured to operate independently with any number of the six loops under various experimental conditions simultaneously.

Heterotrophic bacteria can colonize; pipe surfaces, cracks, and crevices producing a complex micro environment known as "biofilm." These biofilms can be...
