I - DESIGN OF RESERVOIR:
A. Reason for installing a reservoirTo balance the supply and demand in the system.
Supply = 0.93 lps.Demand = 0.838 lps.
B. Location of the reservoir= above service area
Reason for choosing the location.The reservoir is lower than the spring and generally higher than the distribution areas. It is also near to the service area for easy maintenance.
C. Capacity of the reservoir
Criteria:Particular Description Data Unit

Reservoir capacity:
1) By rule of thumb
Reservoir capacity = 1/4 (ADD)= 18.11 cu.m.
2) Theoretical = (Demand-Supply)(Ave. day)
3) Supply = (Supply)(Ave. day)
4) Adopted resultReservoir capacity = 18.11 cu.m.
5) Reason for adoption
- Use an average reservoir capacity which could meet the demand of the future generation.- satisfy and hourly variations in the consumption rate- to provide for repair of pipes (particularly, the transmission) without interruption of service
6) Reservoir dimension Use 2 units reservoir @ 20 cu.m. capacity each

I - DESIGN OF RESERVOIR:
A. Reason for installing a reservoirTo balance the supply and demand in the system.
Supply = 10.2 lps.Demand = 9.229 lps.
B. Location of the reservoir= 34 meters above service area
Reason for choosing the location.The reservoir is lower than the spring and generally higher than the distribution areas. It is also near to the service area for easy maintenance.

7 Difference in elevation between nodes under consideration (meter)8 Computed Pipe Diameter (mm), using the Darcy Weisbach Formula9 Nominal Diameter available in the market (mm)
10 Headloss per 100 meters (refer to table 9.2)11 Actual Headloss
Formula:
Column 6:PF = 2.5 x average flowPF = 2.5 x GRF x N x Average Household Size x PCWC / 86,400
Where:
PF = Peak flow.GRF = Growth rate factor.
N = Total number of household served by the pipe section.PCWC = Per capita water consumption.
Simplifying:
Column 8:
HF = f (L)(Q)^2/D^5D^5 = f (L)(Q)^2/HF
Where:
HF = Headloss or the difference in elevation between the pipe in consideration.
F = Coefficient of friction (approximately 0.02 for G.I. pipe).L = Length of pipe section in consideration.Q = Water discharge.D =Pipe diameter (mm).
