8-13D-9-30: WATER SYSTEM:
Introduction: As discussed in Section 8-13D-29 of this Article, the primary water supply for the Hidden Springs project has been developed as an extension of United Water Company service lines. Lots greater than two and a half (2.5) acres located north of the power lines will be served by individual wells, subject to approval by the required jurisdictional agencies.
United Water Service General Description: The primary water system has been designed in accordance with the Idaho regulations for public drinking water systems, Title I, Chapter 8 Section 1-8200.1, as required by the Idaho Code 39-118 or 50-1326 and the fire code as adopted by the state of Idaho. The system will supply water as the primary agent for fire extinguishment.
United Water Service Demand Analysis: A plan has been prepared for the transmission and storage facilities as well as to guide the design of the distribution facilities for each phase of the planned community. The estimated maximum daily total consumption for all phases is one thousand seven hundred fifty (1,750) gallons per minute, which includes fire demand and a system leakage allowance. The peak demand for any, one-hour period, for all phases is three thousand three hundred fifty (3,350) gallons per minute. The transmission and storage facilities have been designed to accommodate expansion of the system beyond Hidden Springs' original entitlement and can accommodate one hundred twenty (120) additional dwelling units.
United Water Service Storage: Storage for domestic consumption and fire flow demand will be provided from the existing Hidden Springs reservoir. These three hundred fifty thousand (350,000) gallons tank is built, tested, and in service. A second reservoir may be constructed if required to maintain system pressure in development areas north of Dry Creek at relatively high elevations.
United Water Service Zones: Hidden Springs encompasses domestic services that will range over approximately nine hundred (900) vertical feet elevation. This range of elevation will require several service zones. The IRPDWS require a minimum design pressure of thirty-five (35) pounds per square inch (psi) and a maximum pressure of one hundred (100) psi. These pressure criteria will be achieved through the use of eight (8) service zones, with average daily pressures ranging from forty (40) psi at the top of each zone to ninety (90) psi at the bottom of each zone.
Booster pumps located at zone boundaries will supply domestic demands to the higher zones and fill the storage tanks as required north of Dry Creek. Once the tanks are filled, the boosters will be cycled off and supply will come from the tanks down through pressure reducing stations into the lower zones.
United Water Service Distribution Mains: Water mains are required to connect supply, storage and domestic service zones. The IRPDWS require that hydrants be connected to mains six inches (6") and larger in diameter. Other mains will be larger as required for adequate fire flows. The fire code requires that hydrants be spaced at intervals not to exceed five hundred feet (500') for residential fire demands. Hydrant spacing can vary somewhat to accommodate intersections and larger lots. Hydrant spacing near commercial and community structures will be decreased to about three hundred fifty feet (350') or as local conditions require.
United Water Service Meters: This system includes meters for all users. The meter installation includes an automatic readout device located near the meter or at a convenient location nearby. These meters, data storage devices and database software together with a rate structure that promotes conservation are the heart and soul of the water system management structure.
United Water Service to Units: Hidden Springs is committed to providing service to all residential units in the community. The water distribution plan map shows the conceptual layout of the water distribution system and is not intended to document a complete layout of the entire community system. During design and plotting of individual phases, specific design and location for all service lines will be finalized and documented in the appropriate documents.
Individual Wells: The large lots located north of the power lines will have individual, on site wells that will provide domestic water and fire sprinkler water to meet NFPA 13D requirements.
