NC
Residential Water Rate Study, June 2005
Piedmont Triad
COG Region
The North Carolina
League of Municipalities and UNC-Chapel
Hill partnered on a North Carolina
Residential Water Rate Study looking at
2004-2005 water and sewer rates.
Findings for the entire state and
study methodology can be found at www.efc.unc.edu. The following tables display findings for the seven county
PTCOG Region (Guilford, Rockingham,
Caswell, Alamance, Randolph, Davidson
and Montgomery).
The data tables are sorted in
descending order based on 6,000 gallons
of water inside the city limits (tables
1 & 3) or minimum charges inside the
city limits or fixed charges inside the
city limits (tables 2 & 4).
The average monthly household
consumption is roughly 6,000 gallons.
Tables 1 and
2 summarize monthly water rates
and water rate structures
for the PTCOG Region.
Based on a consumption level of
6,000 gallons of water per month within
the city limits, Franklinville has the
most expensive water in the region and
Mayodan has the least expensive.
Reidsville and Yanceyville charge the
most for residents outside the city
limits.
The majority of municipalities in
the PTCOG region use a uniform water
rate structure meaning the rate per
gallon of water used doesn’t change as
water consumption increases. However,
there are four municipalities that use
an increasing block rate structure
(Star, Liberty, Thomasville, and
Greensboro).
An increasing block rate
structure means the rate per gallon of
water used will increase as consumption
increases.
This is a common water
conservation strategy.
Six municipalities in the region
use a decreasing block rate structure
(Mebane, Mount Gilead, Haw River,
Graham, High Point, and Burlington)
where the price per gallon decreases as
the amount used increases.
This is an economic development
strategy.
Tables 3 and
4 summarize monthly sewer rates
and sewer rate structures
for the PTCOG Region.
Again based on 6,000 gallons of
water used within the city limits,
Trinity has the most expensive sewer
charges in the region.
The Town of Alamance has the
lowest.
Mount Gilead charges the most for
residents outside the city limits.
The majority of municipalities
use a uniform rate structure for sewer
charges.
Four municipalities use an
increasing block structure (Star,
Franklinville, Thomasville, and
Liberty).
Only one municipality uses a
decreasing rate structure, Mount Gilead.
