Fairfax County residents who have questions about the county's new emergency water conservation ordinance, or those who have complaints should call 691-2131.

In Alexandria, questions on the city's water conservation ordinance can be answered by the city manager's office, at 750-6201, or the Department of Transportation and Environmental Services at 750-6451 between 9 a.m. and 5 p.m. on weekdays. To make complaints any time, or to get information after normal office hours, call the Alexandria police at 750-6411.

Enforcement of the Fairfax County ordinance began last Saturday, and by last Monday County officials reported that they had received 21 complaints. Of those complaints, they said 12 were unfounded; two people had left the scene before police arrived; four summonses were issued, and three people received warnings.

The maximum fine for violating the ordinance in both Alexandria and Fairfax County is $500.

Fairfax County businesses or individuals who will be impacted economically by the regulations, or who desire an exemption in the interest of health or safety, may put their appeal in writing to: Water Emergency Appeals Board, Office of the County Executive, Fairfax County Government, 4100 Chain Bridge Road, Fairfax, Va. 22030.

Appeals forms are available at all Fairfax County fire stations. Those who do not want to mail their appeals can deliver them to the Citizen's Assistance Desk in the first floor lobby of the Massey Building, 4100 Chain Bridge Rd., between 8 a.m. and 4:30 p.m. weekdays. Forms should not be returned to fire stations, because their processing will be delayed.

Alexandria businesses or individuals who want to receive exemptions should state their appeal and the reason for the appeal, in writing, to City Manager Douglas Harman, 125 N. Royal St., Alexandria, Va. 22313. Appeals will be decided by the city council, but the city manager has the power to grant temporary exemptions until the council meets to consider appeals.

Today is the first day the Alexandria ordinance is to be enforced. Since last Saturday, when it went into effect, police have been giving warnings.
