WATER SUPPLYINTRODUCTION
Definition
Water supply is the process of self-provision or provision by third parties in
the water industry, commonly a public utility, of water resources of various
qualities to different users
Water is a ubiquitous chemical substance that is composed of hydrogen
and oxygen and is vital for all known forms of life

Water Supply System is facilities for the collection, treatment, storage,
and distribution of water
qualities to different users

• Ultimate Demand (Q) = 98.0CuM/day
• Peak factor f = 1.2
• Total pipe length (L) = 15km
• Consider minor losses = 20%
• Bottom Water Level @ TW (B) = 60.0m ODL
• Top Water Level @ Project Site (T) = 40.0m ODL
• Required Residual Pressure (Hr) = 10m
• Design transmission period (t) = 20 hours / 24 hours
Thus
• Design Flow, Qd = Q * f / t
• Permissible Head Loss, HL = (B –T + Hr) / (L * 1.2)

Consider Dominant Flow for water reticulation analysis
Thus,
68Mar 2010
Thus,
Case 1 : (19,175.50 CuM/day x 1000/24/3600 ) + 2 (22.5 lit/sec) = 267 lit/sec
Case 2 : (19,175.50 CuM/day x 1000/24/3600) x 2.5 = 555 lit/sec
