A. 

General. All components of the water system shall meet the Recommended Standards for Waterworks adopted by the Great Lakes - Upper Mississippi River Board of State Sanitary Engineers (New York State Department of Health Bulletin No. 42), latest edition, including all addenda thereto. Waterlines, valves and hydrants shall, in addition, meet the Recommended Water System Design Standards of the Insurance Services Office of New York. The design shall provide that additions to the system can be constructed without interrupting normal service or decreasing fire flows. All components shall be designed to provide present and future service as required by the Master Plan, the Official Map and any water system plan adopted by the Town of Malta. Subdivision water systems shall be connected to the Town system, if feasible.

B. 

Water mains.

(1) 

Pipe and fittings shall be of approved materials and class. Class of pipe and type of material shall be specified according to ground conditions, external loading using specified bedding, and internal pressure as determined by immediate conditions and Town of Malta water system plans. Main sizes shall be as required by the Town in accordance with Town water system plans with no main less than eight inches in size. Dead-end mains shall be avoided whenever feasible. When permitted, however, a blowoff or hydrant shall be installed. An eight-inch main loop longer than the maximum length permitted by the Recommended Water System Design Standards may be permitted, provided that it is temporary and that final construction drawings show intersecting mains conforming to these design standards.

(2) 

In subdivisions where on-site water supply systems will be utilized, a dry water supply system shall be provided within the road right-of-way or utility easement for future use when service becomes available.

C. 

Valves. Valves shall be American Water Works Association gate valves of a type approved by the Town. Valves shall be installed on every branch of an intersection, at every stub provided for future expansion and as required by the New York Fire Insurance Rating Organization Recommended Water System Design Standards.
