Many engineering textbooks, reference books, and design manuals convey procedures for sizing water system distribution and transmission lines. There also are many common computer programs available to aid in the design of complex water systems.
Design engineers should clearly define future water supply expectations before beginning preliminary evaluation of water supply and treatment alternatives. The safe yield of any potential water source is the quantity of water—annual, seasonal, and daily—reliably available to the treatment facility. Water rights are another limiting factor.
Design engineers mustdesign water systems to provide at least 30 psi throughout the distribution system during peak hourly demand conditions (WAC 246-290-230). Water systems mustoperate with pressure throughout the distribution system maintained at or above the approved design pressure (WAC 246-290-420).
A planning documents is required for “expanding” water systems (WAC 246-290-100(2)(e)). An engineer mustprepare the historical water use analysis and, in most cases, the planning document. Both mustaddress the capacity elements in WAC 246-290-100(4).
The design manual is a start-to-finish reference for engineers and others involved in water system design. It covers design, review and approval of sources, storage reservoirs, booster pump stations, water treatment facilities, and other aspects of designing water systems.

Design engineers should consider water system design holistically, so that correcting one water quality problem (e.g., replacing a source, adjusting pH, adding a chemical Water System Design Manual DOH 331-123, June 2020 11 disinfectant) does not lead to new or amplified water quality problems with the source or in the distribution system.
