WPR Tank 5 is a 300,000-gallon concrete storage tank on the
south end of the development within plat 3C. Tank 5 will be filled
from a future booster pump station (200 gpm) drawing water
directly from the culinary distribution system and a designated
transmission (10-inch). Tank 5 will then distribute water to the
southern end of the development through a series of distribution
piping and PRVs to keep pressure below 150 psi. Tank 5 is sized
for 1,500 gpm residential fire flow for 2 hours, peaks day demand
for 81 ERCs, and additional emergency storage.
Tank elevation adequate to serve all present and anticipated future connections
Tank located a minimum of 50 lateral feet from sewers
Ground within 50 foot radius of tank graded to prevent standing water (ground-level & buried tanks)
Site/Location
Tank location provides minimum working pressures per R309-105-9 in distribution system
Size and Volume
Equalization storage volume based on average day demand for indoor and outdoor use
Fire suppression storage volume based on local fire authority requirements or 120,000 gal. (systems with fire hydrants)
Emergency storage volume when required by the Director based on risk assessment
Storage tank sized to meet minimum storage volumes per R309-510
Minimum 30 psi peak instantaneous demand
Minimum 40 psi peak day demand
