A "tariff" means a service charge that the City charges for the use of services it renders such as water and electricity. The prices of these services should be affordable to the people who use the services, and to the City itself. The more electricity or water the consumer uses in a month, the more expensive it is per unit. Other City's tariffs are also called "rates". The consumer's municipal bill usually includes a monthly property rate based on the municipal value of the consumer's house again, the more consumer's house is worth, the more you will pay in rates.
It must be noted that the City has introduced a step tariff for electricity and water services, which implies that the more electricity or water the consumer uses, the more they will pay, with a view to reduce electricity consumption and benefiting lower consumption users. A tariff structure is a set of rules and procedures that determines how we charge different categories of consumers.
The link below provides an example of the practical calculations and impact for two households who consume different kiloliters of water over the City's two financial year periods. This shows the calculation of the step tariff on water consumption for a single dwelling.
