Rates are a function of the number of users in the system. Large localities such as Fairfax County have lower rates spread over a large user base whereas Purcellville has a much smaller user base to cover the cost of the services provided. This is generally referred to as "the economy of scale.” It is also important to note that the level of water and wastewater treatment is dictated by the EPA and the State and the Town must meet those standards irrespective of the costs. The State is requiring several new treatment requirements that are expected to further affect costs. In addition, operations and materials costs continue to increase which further stretch our current resources.
The Town of Purcellville water and sewer rates are based on the volume of water consumed. The amount a resident pays for sewer is directly related to the amount of water used regardless if the use is indoors and sewer-related or outdoors and not sewer related. Water bills are issued for a two month period. Average household use is between 200 and 300 gallons per day without outside water uses such as lawn watering, car washing and pool filling. A lawn sprinkler can use 450 gallons per hour. Outside uses can easily double and triple average household usage. We have also found that residents in new homes may experience higher water use than at their previous home. This could be caused by the high pressure in the Town system. If you do not already have a pressure reducer, installing one may help.
