The eThekwini municipality is planning to build a new residential area of $50$ households. Each household will consist of two sinks$,$ one shower and one toilet. Design a water distribution system in stages starting with demand estimation, pipe sizing requirement, pressure analysis and water tank storage sizing.

Data

$1$ sink consumes approx. $4$Litres$/$minute

$1$ shower consumes approx. $10$Liters$/$min

$1$ toilet consumes approx. $6$L$/$min

Demand factor during peak demand is $0\mathrm{.}4$

Total length of the main supply pipe is $153$m

Allowable frictional loss is $69$KPa

Average daily water per household approx. $378$L

Use Hazen$-$William equation to calculate diameter

Hazen$-$William coefficient for PVC piping is $150$

Determine the following:

$(1)$ Water demand during peak period.

$(2)$ Determine the diameter of the main supply pipe.

$(3)$ Undertake pressure analysis and recommend the required pump size to maintain the peak demand.

$(4)$ Water storage sizing to maintain the peak demand
