$1.$ Identify tools and equipment used when collecting data to analyze water balance

equation

$2.$ Use the data below to answer the questions

a$)$ Water produced: $10,000$ cubic meters$/$day

b$)$ Metered customer consumption: $7,200$ cubic meters$/$day

c$)$ Unmetered authorized consumption: $800$ cubic meters$/$day

d$)$ Water losses due to leaks: $1,000$ cubic meters$/$day

Calculate:

i$.$ Total authorized consumption $(2$

marks$)$

ii$.$ Total water losses $(2$

marks$)$

iii. Non$-$Revenue Water $($NRW$)$ volume and percentage $(2$

marks$)$

$3..$ Given the data

a$)$ Water produced: $300,000$ cubic meters$/$month

b$)$ Billed authorized consumption: $220,000$ cubic meters$/$month

c$)$ Unbilled authorized consumption: $20,000$ cubic meters$/$month

d$)$ Real losses $($leakage$)$: $40,000$ cubic meters$/$month

Calculate:

i$.$ Apparent losses $(2$ marks$)$

ii$.$ Non$-$Revenue Water $($NRW$)$ volume and percentage $(3$

marks$)$

$4.$ Use the provided data to answer the questions below

a$)$ Water produced: $400,000$ cubic meters$/$month

b$)$ Authorized consumption: $350,000$ cubic meters$/$month

c$)$ Water losses $($NRW$)$: $50,000$ cubic meters$/$month

d$)$ Cost of water production: $$0\mathrm{.}50$ per cubic meter

e$)$ Selling price of water: $$1\mathrm{.}50$ per cubic meter

Calculate:

i$.$ Revenue lost due to NRW $(2$

marks$)$

ii$.$ Cost of water lost due to NRW $(2$ marks$)$

iii. Net financial impact of NRW on the utility $(2)$
