In most cities and towns, residents are required to pay for water usage. The payment is known as water tariff or water rate. The calculation of water tariff is an essential task that every individual must understand as it varies depending on the amount of water consumed.
What is Water Tariff?
Water tariff is a fee paid by users for the supply of water. It is a necessary payment, as water is a basic need and requires sustenance. The rate of the water tariff varies according to the local government regulations, the amount of water consumed, and the type of consumer. Water tariffs typically include various costs, such as treatment, distribution, and maintenance costs.
How is Water Tariff Calculated?
Water tariff calculation is dependent on various factors. The cost of water tariff is calculated using the following formula:
Total Cost of Water Supply = Operating Costs + Fixed Investments/Number of Users
Operating costs consist of the expenses incurred in the distribution and treatment of water supply. It includes items such as labor, administration, electricity, chemicals, and fuel costs. The operating costs largely depend on the level and quality of service provided by the water supply company. Higher the service, higher the operating costs.
Fixed Investments include the capital expenditure made by the water authority for the establishment of water supply system. It includes the costs for the construction of water treatment plants, pipelines, reservoirs, and distribution networks. The investment is usually determined by the size of the service area.
Number of Users
The total number of users is simply the number of people using the water supply. The total number of households and commercial establishments serviced is used to calculate the average consumption of water for the population service coverage.
Examples of Water Tariff Calculation
Consider an example of a basic calculation of water tariff:
|Number of Users
Using the above formula:
Total Cost of Water Supply = Operating Costs + Fixed Investments/Number of Users = $150,000 + $70,000 / 1,000 = $220 per user per year
Several other factors influence water tariff calculation, such as seasonality, location, and maintenance costs. Understanding how a water tariff is calculated can help you better manage your water consumption and finances. Being conscious of your consumption and taking simple measures to conserve water can have a significant impact on reducing water tariff costs in the long term.
