Distribution
7.3.1
Distribution System Design and Installation. Design and installation of
distribution systems are normally engineering functions. Basic information, including
planning and layout, sizing mains, pipe materials and selection, pipe handling,
excavation, laying pipe, backfilling, pressure and leak testing, flushing and disinfection,
final inspection, site restoration, and site safety, can be found in the publications listed
in the following paragraphs: 2.1.4, 2.2.22, 2.2.23, 2.2.29, 2.2.16, 2.2.8, and 2.2.7.
7.3.2
O&M. Factors essential to maintaining a dependable water distribution
system include ensuring water quality, providing adequate flows for protection against
fire (fire flow), and maintaining adequate pressure. The operation of a distribution
system consists essentially of setting and operating valves, keeping records of water
flows and levels, and correctly balancing the system flow to maintain the desired
pressure in all parts of the system. General information on system O&M can be found
in the publications listed in pars. 2.1.4 and 2.2.41.
7.3.2.1
Main Breaks and Repairs. Since water main breaks need to be repaired
as rapidly as possible, it is recommended that personnel be trained and repair plans
made in advance. Perform the following tasks to eliminate delay in beginning repairs:
a)
Post telephone numbers of key personnel conspicuously in the
water plant.
b)
Keep the following items available and ready for use at all times:
valve keys, hand tools, digging tools, pavement breakers, trench-shoring material, a
portable centrifugal pump, floodlights, an emergency chlorinator, and calcium
hypochlorite.
c)
Keep a stock of split-sleeve and mechanical-joint repair fittings in
sizes that fit critical mains.
