The Denver Water Nonpotable Reuse Project has been implemented to reuse Denver
metropolitan wastewater, and thereby defer the need to develop new raw water
sources. Denver Water developed a pilot plant for this non-potable reuse project,
which began operation in 1985. Operation of this plant continued until late 1990.
Information from this pilot study was used to develop the necessary data required
to establish the relative safety of reclaimed wastewater as a potable water
supply. This paper discusses the design of the Project's reuse distribution
system which utilized hydraulic modeling. The main objectives of the model
simulations were to refine pipe diameter estimates needed to meet maximum demand
conditions, and to monitor the effects of fluctuating demands on storage volumes
and operating pressures throughout the nonpotable reuse distribution system. Includes 2 references, tables, figures.
