17、desired, and budgetary constraints. The area factors will be determined by a registered landscape professional. Reference is made to UFC 3-210-05FA. While the design of a system with pop-up heads may be justified in some geographic areas, bubbler type systems may be required in areas where water con
18、servation methods are being practiced. If source of water supply is from base water main through a service line and water meter, determine amount of water available for irrigation system from static SECTION 32 84 23 Page 4Provided by IHSNot for ResaleNo reproduction or networking permitted without l
19、icense from IHS-,-,-pressure at point of connection to water main. In many cases, water supply is adequate for short durations only. The amount of water required is determined from the type of turf to be irrigated, climate, terrain, and soil conditions. System piping layout, pipe sizes, and selectio
20、n and spacing of heads and emitters must provide the required amount of water and complete coverage of the irrigated areas. Provide valves to allow irrigation of each area separately.*1.1 REFERENCES*NOTE: This paragraph is used to list the publications cited in the text of the guide specification. T
