Spirits were more than a little dampened when members of a Northern Virginia condominium association received a $12,007.01 water and sewer bill for the month of August.

"They were mad as heck," said Supervisor Elaine McConnell (R-Springfield), who reported the bill at yesterday's Fairfax County Board of Supervisors meeting.

McConnell said officials from the Fairfax County Water Authority and the Fairfax County Department of Public Works, which maintains the county's sewers, charged the 618-unit Meadows of Newgate community in Centreville for six years' worth of water and sewer use not previously detected on the association's 33 meters.

"At first we were shocked," said James M. Cachine, condominium community manager. "We had just finished a water savings program here and had decreased our water consumption. Then out of the blue we receive this adjusted bill."

McConnell, who said tenants have come and gone and that it was unfair to "penalize the tenants . . . for the water authority's negligence," told board members that the water authority has agreed to waive its $3,982.70 portion of the bill. She then asked the public works department to rescind the remaining $8,024.31 sewer charge.

John W. diZerega, director of public works, said his staff will consider McConnell's request.
