1.0 GENERAL
1.1 Project Introduction & Site Location
The owner Majlis Agama Islam Wilayah Persekutuan is proposed project site is located on Lot - lot 4341, 5589 and government lot , Mukim of Ampang,Wilayah Persekutuan Kuala Lumpur
The total project area is 1.44 acres ( i.e., 5,850 m²). The locality of the project site falls under the jurisdiction of Dewan BandarayaKuala Lumpur. The location of the site is attached
1.2 Design Reference & Calculations
a) The design is complying with the Water reticulation system design used by Syarikat Bekalan Air Selangor Sdn Bhd ,SYABAS Guidelines
b) All analysis for water reticulation by Loop Method applied (Hardy-Cross method)
c) Data ODL = 80.0 m (from SYABAS) at existing pipe
d) Total Water Demands in gallon per day ( refer to Table 1 = Average Water Demand (gpd))so, total water demand for this MASJID= 65,200 gal/day so, total water demand for this MASJID= 65,200 gal/day
e) Friction LossUsing Hazen-William FormulaRoughness Coefficient, C = 130 (HDPE) refer data pipeDiameter of Pipes, D = 150mm (for all pipes)
Table data pipe :-
Q = k . C . A . R0.63 . S0.54
dengan Q = Kadar aliran (m3/s)C = Pekali kekasaran Hazen-Williams (tiada unit)A = Luas aliran (m2)R = Radius hidraulik (m)k = Pemalar (0.85 untuk unit SI)
1.3 Design Flow
Peak flow have be determined with formula as follow
Peak Flow = Peak Factor x Average Flow Q peak = f x Q average Where = f = peak coefficient.
Peak coefficient value can determine according to below table: -
a) 1.2 = Peak flow factor for design of pipe from tap-off point to elevated water tank / suction tankb) 2.5= Peak flow factor for design of pipe from tap-off point to individual building under gravity flowc) peak factors to be determined based on the type of distributiond) average flow is the total daily demand requirement divided by 24 hours
Looping and branching system was considered to provide in design criteria
