Opponents of the community’s

long-term water supply plan

on Monday blasted the conclusions reached by an engineering firm hired to review the demand assumptions that serve as the basis of the document.

“We were disappointed when we read the report,” said Dede Smith of

Citizens for a Sustainable Water Plan

. “The actual water usage data that we have seen in the last 10 years, with the full impacts of water conservation, should have been factored in when in fact it was not.”

board is expected to discuss the report at its meeting today.

RWSA Executive Director Thomas L. Frederick Jr. disagreed with the critical assessment.

“From my review of the report, it does take into account conservation of all types that have occurred in the last eight years,” Frederick said in an interview.

Prepared by Steve Swartz of

Swartz Engineering Economics

, the report recommends that the RWSA establish a new demand goal for the water plan of 18.45 million gallons a day for the year 2060.

Swartz reviewed the

2004 study

completed by consultant

Gannett Fleming

, which had previously set a goal of 18.7 mgd for 2055. He concluded in the report that the community experienced a “one-time reduction in demand” caused by a variety of factors, including the 2002 drought, and that “data from the past 16 years do not indicate any change to long-term trends.”

The report indicates that increased enrollment at the University of Virginia, combined with increased commercial and residential growth in Charlottesville and Albemarle, will drive local population growth, and thus water demand.

Smith emphasized in her remarks the importance of the 1992 federal Energy Policy Act, which she said would significantly reduce household water usage by requiring more efficient toilets, showerheads and faucets.

“The report does not even mention federal [water efficiency] mandates that have come into place since the 2004 demand study that have dramatically impacted our water use,” Smith said.

Frederick said the Gannett Fleming “trend line from 2004 also took into account future conservation.”

comparing Swartz’s demand trend to that of a linear trend of actual water usage since 1983.

At Monday’s news conference, group member Rich Collins characterized the RWSA as “so committed to its early permitted activity that it is unwilling to explore, much less to decide on, a better option.”

Collins said his group’s alternative water plan, which has dredging as its centerpiece to create more storage capacity, would provide 14 million gallons a day to 16 million gallons a day in “safe yield” for the water supply in 2060. Charlottesville Mayor

Dave Norris

, who also sits on the RWSA board, has indicated the City Council should soon be ready to make a decision on the next steps for the water plan.

“I personally am reserving judgment until I have heard from Mr. Swartz,” Norris said in an interview. “If he is not able to demonstrate how his report adequately incorporated … conservation and efficiency, that would give me pause with regard to proceeding with a massive new dam that we may not need.”

“That’s the beauty of the [alternative] plan, we know because of studies we have done that dredging will produce a significant amount of water and the first phase can be done at relatively low cost,” Norris said. “While I am not endorsing it yet, there is an argument to proceed with dredging in the short run.”

Ann Mallek

, the chairman of the Albemarle Board of Supervisors, said she was comfortable the Swartz study was pointing the community in the right direction to satisfy its long term water needs.

“Demand needs to be based on a long period of time, not just a short period that supports your point of view,” Mallek said in an interview.

“The extra use anticipated by the University of Virginia and future industrial needs all show that we are in the right ball park,” Mallek said. “It wouldn’t bother me to have a water supply that would last to 2060 or 2070. That’s what our citizens want us to do, to plan for the infrastructure that we need.”
