The revenue is likewise used to pay the workers who provide yous with water service day or night. At that place are a wide variety of rate structures that are used to bill customers, some of which are described below.
Rate Types
Flat Fee, Uniform Rate, Increasing Cake, Declining Block, Seasonal, Drought, and Water Upkeep
Apartment Fee is a rate structure where all customers are charged the same fee, regardless of the amount of h2o used. Flat fees are the simplest type of rate construction and are rarely used today. They more often than not don't provide revenue sufficient to operate the utility and are not skilful at promoting water efficiency.
 | Uniform Rate is a construction that has a constant per unit cost for all metered units of water consumed on a twelvemonth-round basis. It differs from a apartment fee in that it requires metered service. Some utilities charge varying user groups different rates such as charging residential households one rate and industrial users a dissimilar rate. Constant block rates provide some stability for utilities and encourage conservation because the consumer beak varies with water usage. |
 | Increasing Cake Rates is a rate construction in which the unit toll of each succeeding block of usage is charged at a college unit of measurement charge per unit than the previous block(southward). Increasing block rates are designed to promote conservation and are about often establish in urban areas and areas with limited water supplies.

This rate structures are popular in rural areas that service large farming populations or areas with large users such every bit heavy industry and where water is plentiful. |
 | Seasonal Rates are rates that cover a specific fourth dimension period. They are established to encourage conservation during peak utilize periods. Examples of seasonal rates may exist increases for the summer season due to increased demand associated with lawn watering and exterior activities. |
 | Drought Rates are similar to seasonal rates merely instead of applying higher rates during an unabridged time period, they adjust rates based on the local area'southward drought level. Higher levels of drought result in higher prices for h2o in order to encourage conservation. |
 | Water Budget Based Rates is a rate structure where household are given a "water upkeep" based on the anticipated needs of that household either by the number of people living in the house and/or property size.

| Many utilities use a combination of a fixed fee (base of operations) and a variable fee (volume) for their water rate structure. Fixed charges generally include the price the client pays as a base of operations charge to aid cover costs for maintaining existing infrastructure and repaying loans and bonds used to build that infrastructure. Variable charges are the toll the client pays per volume of water used, which reflect the costs of providing water, such as costs for chemic treatment to provide safe h2o and energy to movement and evangelize water. | |
What are my charges going towards?
Most utilities volition provide you lot with a breakdown of charges in your "billing item" or "summary of charges" section. Two examples are provided below.
In the first instance, roughly half of the $147.62 being charged is directly related to h2o use. Some utilities measure both water entering the house and waste material leaving to the sewer, but many utilities take only one meter on location and volition charge both volumes based on h2o entering the house. This is nonetheless another reason to reduce your own water apply. Nearly utilities accuse a set flat fee (the "Water Base Facility Charge" in the case) that helps to pay for the base costs of providing water including the electricity needed to transport and clean the water, the personnel and others costs of daily maintenance of the delivery system and other fixed operating costs.
This utility uses a uniform charge per unit structure that charges the user $0.00295 per gallon (or roughly three cents for every 10 gallons) used during the billing menstruum. The bill too shows a similar facility charge for sewer and a "rate case expense surcharge" to assist pay for the utility's charge per unit setting process. The "regulatory assessment fee" helps the utility pay for costs associated with maintaining regulatory compliance with clean water statutes. Finally, some utilities charge fees like to the "Deferred Capital Expense Surcharge" which puts money into a fund to help pay for long term investments in improvements to infrastructure such every bit new pipes, treatment facilities or reservoirs.
This second bill is an instance of an efficient user with an increasing block rate construction. You can run across that the utility has even labeled the various blocks with its corresponding water use efficiency level. The above user falls into the "Efficient" grouping then avoids the much college per unit of measurement costs of the next three tiers. Some utilities will forgive various surcharges for its most efficient users because their below average water apply places less burden on the system and reduces demand for new sources of water and pipes to send this water.
