Water System Design Manual
This edition of the Water System Design Manual is for water system design in Washington, especially for small water systems serving fewer than 500 residential connections. However, the Department of Health (DOH) recognizes that existing local ordinances, consumer service expectations, and existing water use data often provide more appropriate design criteria. DOH advocates the use of water system specific information, especially accurate meter records, for
existing water system expansions.
