Roanoke and its neighboring counties are preparing water-supply plans due in 2029. The important questions are not just where the water comes from, but how future demand is counted.
Before a community can judge whether its water supply will support future growth, it needs a defensible estimate of how much water that growth will require. Across the Roanoke region, that work is part of a state-required planning process with an October 9, 2029 deadline.
The Roanoke Valley-Alleghany Regional Commission is coordinating two regional plans. Together, they cover communities from Alleghany County to Franklin County. Local governments and water suppliers provide the information used to build them.
This is not a notice of a water shortage. The commission describes water-supply planning as a routine, state-mandated process rooted in Virginia’s response to the 2001–2002 drought. Its purpose is to look ahead, rather than wait for a supply problem to arrive.
Two plans, different groups of localities
According to the commission’s project page, the Roanoke River 1 planning unit includes Bedford, Franklin and Roanoke counties, plus the cities of Roanoke and Salem.
The Upper James River 2 planning unit includes Alleghany, Botetourt and Craig counties, plus the city of Covington. Incorporated towns participate in the same planning area as their county.
Those groupings organize the planning work. They should not be read as a statement that every participating community shares a single utility, reservoir or water bill.
The forecast has to look beyond population
Virginia’s submission requirements call for local information on water sources, existing use, water resources, demand management and drought response. They also require a 30-year demand projection and alternatives for addressing deficits against existing supply.
The rules for projected demand make the underlying assumptions important. For community water systems, plans must estimate both annual-average and peak-monthly demand. They must also break demand into categories appropriate to each system.
The regulation lists residential use, commercial and light-industrial use, heavy industry, water used in production, unaccounted-for losses and sales to other systems among the typical categories. It requires the sources and methods used for demand projections to be documented.
That gives readers a concrete way to examine a future plan. A population forecast alone will not explain every change in water use. The treatment of industrial demand, losses and conservation can also affect the result. And an annual average can conceal pressure that appears during the busiest month.
What the public should look for
When draft plans and supporting records become available, three questions will help separate an informative forecast from a headline number.
- What growth is included? Look for the population estimates, service-area assumptions and categories of future demand. Check whether the document explains how it treats proposed development rather than assuming every announced project will be built.
- What happens at peak demand? Compare annual-average use with peak-monthly requirements. They answer different questions about the demands placed on a system.
- What changes if conservation works? Examine demand-management assumptions and any alternatives proposed where projected demand exceeds existing supply.
These are reporting questions, not findings that a locality has omitted information or miscalculated its needs. The regional overview and state rules establish what the process is supposed to produce; they do not establish whether the eventual plans will meet that standard.
What remains unanswered
The records reviewed for this article do not establish a current regional planning-funding shortfall, a new charge to customers, an approved supply expansion or a present shortage. They also do not provide a final demand forecast for either planning unit.
The next useful records will be draft forecasts, the assumptions behind them, any proposed supply alternatives and the decisions needed to carry those alternatives out. The 2029 submission deadline matters. What goes into the plan matters just as much.
