Through the above simple exercise, it is suggested in the case of XXX WASHCO
that each household shall be requested to make a monthly payment with an
amount of Birr 8.35 in order to reach the O&M cost recovery.
Example:
Required amount of monthly revenue: Birr 480.00
Monthly amount of water production (quantity): 130.0 m
3
Required tariff: 480.00 / 130 = 3.70 Birr / m

Monthly consumption per household:
Daily consumption: 15 liter per person per day
Average size of a household: 5 people
Daily Household consumption: 15 l/c/d x 5 = 75 liter
Monthly household consumption:75 x 30 (days) = 2,250 liter
Monthly household consumption-2: 2,250 / 1,000 = 2.25 m
