6.0 WATER DEMAND MANAGEMENT INFORMATION
The Local and Regional Water Supply Planning Regulation (9 VAC 25-780-110) requires the
Plan to address conservation as a part of overall water demand management in accordance with
practices for more efficient water use, water conservation measures through reduction of use, and
practices to reduce water loss. 1 Water conservation as part of overall water demand management
for the MRPDC, Cumberland Plateau, and LENOWISCO regions is described in the following
sections.
Information on water demand management was obtained in large measure through a written
survey of the communities and water suppliers in the MRPDC, Cumberland Plateau, and
LENOWISCO regions. For the Cumberland Plateau region, the survey was reviewed with
representatives of water suppliers during a regional water round table meeting with water
suppliers, hosted by the Planning District Commission (PDC). Surveys were completed at the
meeting by the localities in attendance. Other localities in the planning area were contacted by
phone or received a copy of the survey. For the LENOWISCO region, the survey was reviewed
with representatives of water suppliers during a meeting with water suppliers and local officials.
The majority of the surveys were completed during the meeting and the remainder was returned
within a week. A follow-up survey was distributed to address additional aspects of water demand
management.
Please note that the survey responses reflect the water suppliers’ and localities’ interpretations of
the survey questions. Where possible, responses were reviewed and validated with existing data
or known practices.
6.1 Practices for More Efficient Use
As required by 9 VAC 25-780-110, the Plan includes information that describes practices for
more efficient use of water that are used within the region. The type of measures described may
include, but are not limited to, the adoption and enforcement of the Virginia Uniform Statewide
Building Code (VUSBC) sections that limit maximum flow of water closets, urinals and

appliances; use of low-water use landscaping; and increases in irrigation efficiency. This section
describes current practices in the region for more efficient water use.
6.1.1 Building Codes
The VUSBC is a state regulation promulgated by the Virginia Board of Housing and Community
Development (Board). The Board is appointed by the Governor of Virginia for the purpose of
establishing minimum regulations to govern the construction and maintenance of buildings and
structures. The provisions of the VUSBC are based on nationally recognized building and fire
codes published by the International Code Council, Inc. The 2003 editions of the International
Codes are incorporated by reference into the VUSBC.
6.1.1.1 MRPDC
The following jurisdictions in the region have adopted the VUSBC: the City of Bristol; the
counties of Bland, Carroll, Grayson, Smyth, Washington, and Wythe; and the towns of
Abingdon, Damascus, Fries, Glade Spring, Hillsville, Independence, Marion, Rural Retreat,
Saltville, and Troutdale. The VUSBC requires 1.6 gallon-per-flush toilets and limits the
maximum allowable flow rates for showerheads and faucets to 1.5 gallons-per-minute. The
codes are enforced by each County’s Building Official. In addition, each County enforces the
codes in the towns within the County.
6.1.1.2 Cumberland Plateau
One locality in the planning area reported having approved an ordinance that adopted the
VUSBC sections that limit maximum flow of water closets, urinals, and appliances.
Adoption of building code sections may not lead to more efficient use of water. For example, a
recent article on plumbing codes and water efficiency noted that showerheads are limited to 2.5
gpm under the federal Energy Policy Act; however, the regulation does not limit the number of
showerheads installed in any one shower, and multiple showerhead systems are reported as the
fastest-growing trend in the home building industry. 2

6.1.1.3 LENOWISCO
Two towns in the planning area reported having approved an ordinance that adopted the VUSBC
sections that limit maximum flow of water closets, urinals, and appliances. Both localities
implement the building codes through the County Building Official.
Adoption of building code sections may not lead to more efficient use of water. For example, a
recent article on plumbing codes and water efficiency noted that showerheads are limited to 2.5

6.1.2 Other Practices for Water Use Efficiency
6.1.2.1 MRPDC
In addition to adopting the VUSBC, the WCSA and Town of Saltville implement additional
water use practices for more efficient water use. The WCSA implements a block rate structure,
which increases with water use, and does not offer irrigation credits for sewer service requiring
irrigators to invest in irrigation meters. The Town of Saltville has an ongoing Leak Detection
Analysis Plan. The Town of Saltville did not provide a copy of this plan; therefore, specific
details regarding the plan are not available at this time. There are no other ordinances or policies
in place regarding more efficient water use for the City of Bristol; the counties of Bland, Carroll,
Grayson, and Wythe; or the towns of Fries, Independence, and Rural Retreat.

through reduction of use include, but are not limited to, adjusting standard operating procedures
to improve water conservation and installation of low-flow and/or no-flow fixtures (faucets,
showers, urinals) in facilities or in local government buildings/facilities to improve water savings
to the locality through reduction of use.
In 2004, Bland County installed low-flow and/or no-flow fixtures in local government
buildings/facilities. Wythe County adopted an ordinance (No. 1996-4) to address water
conservation practices through reduction of use. A copy of the ordinance was not provided and
specific details are not available at this time.
On October 22, 1986, the Town of Hillsville adopted ordinance number 167-40 to address water
conservation through the reduction of use as well as to address water emergencies. In addition,
the Town of Hillsville amended their standard operating procedures for filter backwash to
improve water conservation. Filter wash cycles are as long as possible while still meeting VDH
requirements. Finally, the Town of Hillsville installed low-flow urinals in their WTP as well as
the Town Hall.
In the Town of Marion, contractors install low-flow or no-flow fixtures in all new construction in
the area. In addition, Marion has upgraded the majority of toilets and shower heads in local
government buildings to low-flow fixtures.
While Washington County has not adopted an ordinance to address water conservation practices
through reduction of use, the WCSA identified approximately 200 miles of galvanized pipe in
their distribution system as a significant source of non-revenue or unaccounted for water. The
WCSA believes that the galvanized pipe accounts for approximately half of their 37 percent non-
revenue water and proposes to replace the pipe by or before the year 2020. In addition, the
WCSA amended their standard operating procedures for filter backwash in their water
production facilities to improve water conservation and installed low-flow and/or no-flow
fixtures in all facilities.
Carroll County, Smyth County, City of Bristol, City of Galax, Town of Fries, Town of
Independence, Town of Rural Retreat, Town of Saltville, and the Town of Wytheville currently

- Availability of “yard taps” to customers to monitor outdoor water use.
All residential service connections throughout the planning region are required by the
water suppliers to be metered. The cost of water to the customer has resulted in
customer-directed monitoring of water consumption for outdoor use.
In most localities where sewer service is available, sewer billing is based on metered
water consumption. In some cases, this is thought to have resulted in customer requests
for separate meters for outdoor water use, to avoid sewer charges for usage that is not
directed to the wastewater treatment facilities. In turn, outdoor water use is then
monitored directly by the customer.

6.2.2.2 Cumberland Plateau
Much of the educational effort in the planning region on water conservation has resulted due to
recent drought conditions that impacted local suppliers and residents. Two water suppliers offer
tours of water production facilities to the public. Seven localities/water suppliers include
mailings sent with bills, and five issue special mailings as warranted. A number of localities

6.3 Practices to Reduce Water Loss
As required by 9 VAC 25-780-110, the Plan includes information that describes practices to
address water loss in the maintenance of water systems to reduce unaccounted for water loss.
The types of items described may include, but are not limited to, leak detection and repair and
old distribution line replacement. This section describes practices to reduce water loss in the
region.
Water loss may be real (such as from a leak) or apparent (due to meter under registration,
unauthorized consumption). Due to ambiguity in application of the term “unaccounted for water
loss,” the American Water Works Association Water Loss Committee defines water loss as the
difference between volume of water input to the distribution system and the volume of
authorized consumption (this is reviewed in the publication AWWA M36 Water Audits and
Leak Detection). Water utilization may also be described as revenue water (the authorized
consumption that is billed) and non-revenue water (unbilled authorized consumption, apparent
losses, and real losses). All water is accounted for in either description.
6.3.1 Source and/or Service Connections
6.3.1.1 MRPDC
The following have source and service meter connections: Wythe County, Smyth County, the

6.3.3.2 Cumberland Plateau
There are no known ordinances in place that require water users to repair leaking fixtures,
appliances, or plumbing.
Water suppliers track water accountability on a monthly basis, and budget for corrective
maintenance activities.
Five water suppliers dedicated funds in their capital improvement plans toward water line
replacement. Half of the water suppliers record a description of each leak or break (type of leak,
pipe material and age, conditions), and most water suppliers maintain a written summation of
leaks and breaks.
Water suppliers address water leaks with specific responses. All water suppliers report having
emergency call out procedures for water outages, breaks, and leaks. Most water suppliers
reported removing old lines from service upon installation of a replacement line, and all
suppliers relocate taps when a new line is installed. Nearly all water suppliers in the planning
area replace a joint of water line after a specified number of repairs on that joint (such as
between three and ten leak repairs).
6.3.3.3 LENOWISCO
Five water suppliers dedicated funds in their annual budgets toward water loss activities. The
majority of water suppliers budgeted for corrective maintenance activities.
Water suppliers address water leaks with specific responses. Twelve water suppliers report
having emergency call out procedures for water outages, breaks, and leaks. Eight water suppliers
reported removing old lines from service upon installation of a replacement line, and eleven
suppliers relocate taps when a new line is installed. Eleven water suppliers in the planning area
replace a joint of water line after a specified number of repairs on that joint (most commonly
between three and ten leak repairs).
Several water suppliers have instituted valve maintenance and exercising programs. In addition
to reducing water loss due to valve leaks, these programs reduced water loss during leak
detection and repair activities by enabling rapid isolation of the leak and stopping water flow.

6.3.4 Unauthorized Connections
6.3.4.1 MRPDC
The following have practices in place to identify unauthorized water connections: Carroll
County, Wythe County, Town of Hillsville, Town of Wytheville, and the WCSA. Carroll
County Fire Department and County employees monitor fire hydrants for illegal use; and in
Wythe County any use by the fire department is reported within 24 hours and all other use
requires a permit. The Town of Hillsville indicated that practices and policies are in place to
track unauthorized connections; however, specific details are not available at this time. The
Town of Saltville implements policies to track unauthorized connections. In the Town of
Wytheville, town employees regularly monitor fire hydrants for unauthorized connections. The
WCSA meter department and maintenance department monitor their water system for
construction activity where unauthorized connections may occur. In addition, the WCSA
recently began a fire line connection audit to locate and correct illegal connections.
6.3.4.2 Cumberland Plateau
Unauthorized connections may be permanent or temporary. They may also result from
inappropriate modification of an authorized connection or an unauthorized connection made on
an authorized connection.
Temporary connections are often made to fire hydrants. Nearly all of the water suppliers limit
hydrant use to water system personnel and fire department personnel. Two localities have a
written hydrant use policy and three water suppliers allow non-emergency use from hydrants if
metered.
A common inappropriate modification of an authorized connection is a straight pipe that has
been inserted in the place of the meter. This may occur after the meter has been removed due to
non-payment for service, or may result from an attempt to bypass the meter. Water suppliers’
efforts to track this type of modification are informal, and include periodic evaluations of meter
connections.

that does not exceed 150 psi. The high system pressures are due to the topography of the service
areas.
Water loss is positively correlated with system pressure. Nearly all water suppliers operate
pressure reducing valves/stations (PRVs) to reduce pressure appropriately. Half of the water
suppliers require customers to maintain an individual pressure reducing device on the customer
side of the meter.
All water suppliers reported access to distribution system mapping, many of the water systems
have been modeled hydraulically, and one water supplier reported using AWWA’s water loss
analysis computer program. One water supplier maps the location and estimated volume of leaks
and breaks in its distribution system.
6.3.7.3 LENOWISCO
