WATER DISTRIBUTION

Design Requirements

A. GENERAL TRANSMISSION AND DISTRIBUTION SYSTEM REQUIREMENTS

1. Piping

a. The minimum water distribution main size shall be 8".

b. Pipes connecting hydrants to mains shall be at least 6 inches in diameter and not longer than 10 feet.

c. Dead end lines are not permitted except where specifically authorized by PW for special situations, i.e. it is not practical to loop the line at this time.

d. Provide thrust blocking or restrained joints at all fittings and bends.

e. Provide anchor blocking at all up-thrust vertical bends.

f. Minimum size service lines shall be 3/4 inch. Otherwise all service lines shall be the minimum size specified by the Uniform Plumbing Code in accordance with fixture units. Provide stop valve "O" ring seal on all service lines under 2 ½".

g. All water supply and distribution main construction shall have minimum 30" cover from finished grade. The maximum cover shall be 5'-0" cover unless approved by the Installation.

h. All transmission and distribution piping and water services shall have buried directly above, a No. 12 insulated copper tracing wire.

i. Provide water meters for all new buildings - See Section 2.9.8, Meters, for requirements.

2. Horizontal Location

a. New mains shall generally be located parallel to street centerline and off-street in landscaped areas if available.

b. Water mains should be laid horizontally, a minimum of 10 feet, from any point of existing or proposed sewer or drain line. Water mains and sewers must not be installed in the same trench. If any conditions prevent a horizontal separation of 10 feet, a minimum horizontal spacing of 6 feet can be allowed, but the bottom of the water main must be at least 12 inches above the top of the sewer.

Where water mains and sewers follow the same roadway, they will be installed on opposite sides of the roadway, if practicable.

c. Where water mains and sewers must cross, the sewer shall have no joint within 3 feet of the water main unless the sewer is sleeved with pipe two sizes larger than the water main for a distance of at least 10 feet each side of the crossing. If special conditions dictate that a water main be laid under a gravity-flow sewer, the sewer pipe should be fully sleeved with pipe two sizes larger than the water main for a distance of 10 feet each side of the crossing.

A minimum vertical distance of 2 feet between the bottom of water pipe and the top of pressure sewer pipe shall be maintained. The sewer must be adequately supported to prevent settling and insure designed slope is maintained. See also TM5-813-5.

SECTION 33 11 00 Page 2

3. Valves

a. Valves shall be installed at intervals not greater than 5,000 feet in transmission lines and 1,200 feet in distribution loops.

b. At the intersections of distribution mains, the number of valves required is normally one less than the number of radiating mains. A cross will have 3 valves and a tee will have 2 valves. The omitted valve will be from the line which principally supplies flow to the intersection.

c. Valves shall be installed on laterals serving fire hydrants.

d. Blowoff valves or fire hydrants should be installed at the ends of dead-end mains to allow periodic flushing of the mains. Primary feeder mains and larger distribution mains should have a blowoff valve in each valved section which should be installed at low points in the mains where the flushing water can be readily discharged to natural drainage channels. Blowoff valves must be designed so that operation which will result in erosion or destruction of wildlife is not permitted. Special care must be taken to eliminate the possibility of contaminated water entering the distribution system through blowoff valves which have not been tightly closed.

e. Valve marker posts shall be provided for all valves placed outside of paved areas. All valve marker posts shall be marked with the distance to the valve referenced.

4. Fire Hydrant Spacing

a. Hydrant distribution shall conform to the standards shown in Table

III-1 and spacing shall conform to the guidelines given in UFC 3- 600-01.

Required Fire Flow, GPM

Average Area Per Hydrant, Square Feet

b. Fire Hydrants in residential areas shall be located at street intersections. Each single or duplex family unit will have at least one hydrant within 300 feet and a second hydrant within 500 feet. If additional hydrants are needed to meet these criteria, hydrants will normally be located halfway between intersections for airfield hangar areas, hydrants shall be spaced approximately 300 feet apart, and where economically feasible will be connected to the base distribution system and not to the special system serving deluge sprinkler systems in the hangars. For aircraft fueling, mass parking, servicing, and maintenance areas, the fire hydrants will be installed along the edge of aircraft parking and servicing aprons.

Hydrants shall be spaced approximately 300 feet apart so that every part of the apron may be reached by approximately 500 feet of hose.

Hydrants so located are not a hazard to moving aircraft, and no waiver of the provisions of AFR 85-5 is required. One or more hydrants will be located within 300 feet of all operational service points

c. Where an adequately sized water main is available, or can be made available for an individually sited building such as a Reserve Center, two hydrants will be installed. However, one hydrant at the site is acceptable if the provision of a second hydrant would require extension of a water main beyond the point necessary to serve the domestic demands of the building.

d. In aircraft fueling, mass parking, servicing, and maintenance areas, the tops of hydrants will not be higher than 24 inches above the ground with the center of lowest outlet not less than 18 inches above the ground. The pumper nozzle will face the nearest roadway.

5. Fire Hydrant Location

a. Hydrants shall be located at least 50 feet from the buildings protected and in no case will hydrants be located closer than 25 feet to a building, except where building walls are blank firewalls.

b. Street intersections are preferred location for fire hydrants.

Hydrants in areas with sidewalks and/or curbs shall be located as shown on Detail W-6. Hydrants in other areas shall not be located less than 6 feet nor more than 7 feet from the edge of a paved roadway surface. If hydrants are located more than 7 feet from the edge of the paved roadway surface and if the shoulders are such that the pumper cannot be placed within 7 feet of the hydrant, consideration may be given to stabilizing or surfacing a portion of wide shoulders adjacent to hydrants to permit the connection of the hydrant and pumper with a single 10-foot length of suction hose. In exceptional circumstances, it may not be practical to meet these criteria, and hydrants may be located to permit connection to the

SECTION 33 11 00 Page 4 pumper using two lengths of suction hose (a distance not to exceed 16 feet).

c. Hydrants shall not be placed closer than 3 feet to any obstruction nor in front of any entranceways. The center of the lower outlet should not be less than 18 inches above the surrounding grade and the operating nut should not be more than 4 feet above the surrounding grade.

d. In aircraft fueling, mass parking, servicing, and maintenance areas, the tops of hydrants will not be higher than 24 inches above the ground with the center of lowest outlet not less than 18 inches above the ground. The pumper nozzle will face the nearest roadway.

B. WATER PROJECT APPROVAL PROCESS

a. Washington State Department of Health (DOH) must review and provide written approval for all projects involving the construction of "any new water system, water system extension, or improvement" (WAC 246- 290-110). The construction document must include, at a minimum, drawings, material specifications, construction specifications, assembly techniques, testing, disinfection and inspection. Projects submittals should follow guidance in the DOH Design Manual.

b. All submittals for DOH review must be sent to the Government (Joint Base Lewis-McChord Water System Manager) for review and approval.

The Government will review the project submittals and direct the designer to forward the submittals for DOH review to the Washington State DOH once all needed corrections are made.

c. The following require DOH approval before the project proceeds:

water system plans, new drinking water sources, new Group A water systems, additions or changes to treatment, anything in contact with drinking water (reservoirs, pumps, booster stations, etc), and interties.

d. The following are approval exemptions: installation of valves, fittings, meters, and backflow preventers; installation of hydrants; repair or replacement of a component with a similar capacity or material; and distribution main extensions (if approved, the Water System Comprehensive Management Plan (WSCMP) contains construction specifications). If a capital improvements project is not included in the approved WSCMP then approval from the DOH is required. If Joint Base Lewis-McChord identifies additional capital improvement projects (e.g. all concrete reservoirs to be relined) then there is an option to submit an addendum to the WSCMP for review instead of individual submittals. The addendum is subject to the review process.

e. All fees associated with each DOH review shall be included as part of the Architect-Engineer's costs.

Notes to Designers on Drawing Content

a. Detailed plans shall be submitted for review which provide the locations, size, and type of the proposed water system and points of connection. These Plans shall be separate from sewer plans unless otherwise directed by Public Works.

b. All survey control shall be based on the nearest Corps of Engineer’s benchmarks. Project plans shall have a horizontal scale of not more than 50 feet to the inch. Plans shall show: Locations of streets, existing utilities and water system facilities, ground surface, pipe size, water valve and hydrant stationing, utility easements, all

SECTION 33 11 00 Page 5 known existing structures, both above and below ground, which might interfere with the proposed construction, particularly sewer lines, gas mains, storm drains, overhead and underground power lines, and telephone lines and television cables.
