Article 10, Chapter 67.1 of the County Code, which establishes these rates. They were approved by the Board of Supervisors as part of the FY 2019 Budget, on May 7, 2019.
The base charge changes are presented in the table.
The sewer base charge is based on account type and meter size. The larger the meter size, the higher the base charge. The sewer base charge is collected to partially recover fixed expenses to operate and manage the system, which continue to increase. The aging system and increased regulatory requirements are contributing factors.
|METER SIZE||Through 6/30/2019||Service After 7/1/2019|
|3/4" and smaller, Residential, as well as Fixture Accounts||$30.38||$32.91|
|10" or larger||$3,493.70||$3,784.65|
For accounts with more than one main meter, the base charges will be added and appear on the bill as one line item. Sub-meters will not be charged a sewer base.
Effective with service rendered on July 1, 2019 or later, the residential customers are billed for use of the sanitary sewer system at a rate of $7.28 per 1,000 gallons.

This prevents residential customers from being charged sewer rates on water used outdoors during the summer.

Effective service rendered on July 1, 2019 or later, the commercial customers are billed for sewer use based on their actual water consumption at a rate of $7.28 per 1,000 gallons. Some commercial customers use meters to separately measure water that does not drain to the sanitary sewer system, such as water used for irrigation or cooling systems. These metering arrangements do not benefit residential customers, whose winter quarter water consumption limits the amount of sewer usage billed in the summer months.

City of Falls Church
On April 22, 2019, Falls Church City Council decided to maintain the current rates for another fiscal year. The rates originally effective with service rendered July 1, 2016 will continue to be effective through June 30, 2020.
A fixed charge of $6.00 for quarterly bills and $2.00 for monthly bills is paid to the City of Falls Church to partially recover administrative and customer service costs.
Residential customers are billed at a rate of $9.87 per 1,000 gallons. It is based on winter quarter water consumption or the actual water consumption during the current billing period, whichever is lower. This prevents residential customers from being charged sewer rates on water used outdoors during the warmer months because it does not drain to the sanitary sewer system. The City of Falls Church prorates this amount on initial and final bills based on average winter quarter consumption.
Non-metered Services - Single-family residences are billed on the basis of per capita average of similar users. These customers are charged based on the number of persons residing in the home.
Commercial customers are billed at a rate of $9.87 per 1,000 gallons. It is based on actual water consumption. Some commercial customers use additional meters to separately measure water that does not drain to the sanitary sewer system, such as water used for irrigation or cooling systems. Residential customers would not benefit from this type of metering because their winter quarter consumption already limits the amount of sewer usage billed in the summer months.
Water and sewer utility taxes are assessed by and collected for the City of Falls Church. Residential customers are taxed on water and sewer at a rate of 10 percent each, with a maximum of $15 each. Commercial customers are taxed on water and sewer at a rate of 8 percent each, with no maximum.
