UTILITY PROFILE
The purpose of the Utility Profile is to assist with water conservation plan development
and to ensure that important information and data be considered when preparing your
water conservation plan and its target and goals. Please complete all questions as completely and objectively
as possible. See Water Conservation Plan Guidance Checklist (WRD-022) for information on other water
conservation provisions. You may contact the Municipal Water Conservation Unit of the TWDB at 512-9362391 for assistance.

Please indicate how the above figures were determined (e.g., from a master meter located at the
point of a diversion from a stream or located at a point where raw water enters the treatment plant,
or from water sales).
The above figures were determined using master meters at Sandy Point Pump Station and
Dowling Road Pump Station, and from water billing records. The figures represent water
pumped in the wellfield. Due to water loss at the cooling towers, this total is greater than water
pumped into the distribution system.

Appendix A
Definitions of Utility Profile Terms
1.
Residential sales should include water sold to residential (Single and Multi-Family) class customers
only.
Industrial sales should include water sold to manufacturing and other heavy industry.
Commercial sales should include water sold to all retail businesses, offices, hospitals, etc
Wholesale sales should include water sold to another utility for a resale to the public for human
consumption.
2.
Water Loss is the difference between water a utility purchases or produces and the amount of water
that it can account for in sales and other known uses for a given period. Water loss can result from:





inaccurate or incomplete record keeping;
meter error;
unmetered uses such as firefighting, line flushing, and water for public buildings and water
treatment plants;
leaks; and
water theft and unauthorized use.
3.
The peak-day to average-day ratio is calculated by dividing the maximum daily pumpage (in
million gallons per day) by the average daily pumpage. Average daily pumpage is the total pumpage
for the year (as reported in Section IIA1, p. 4) divided by 365 and expressed in million gallons per
day.
4.
Total use in gallons per capita per day is defined as total average daily amount of water diverted
or pumped for treatment for potable use by a public water supply system. The calculation is made by
dividing the water diverted or pumped for treatment for potable use by population served, then
dividing by 365. Indirect reuse volumes shall be credited against total diversion volumes for the
purpose of calculation gallons per capita per day for targets and goals developed for the water
conservation plan. Total water use is calculated by subtracting the wholesale sales from the total
water diverted or treated (as reported in Section IIA1).
5.
Seasonal water use is the difference between base (winter) daily per capita use and summer daily
per capita use. To calculate the base daily per capita use, average the monthly diversions for
December, January, and February, and divide this average by 30. Then divide this figure by the
population. To calculate the summer daily per capita use, use the months of June, July, and
August.

Attachment 3: Description of Water System
Reference Item III. B. 4 on Utility Profile:
College Station pumps water from six deep wells located about 13 miles northwest of the city, in the vicinity
of Sandy Point Road and Old San Antonio Road. These wells draw water from the Simsboro Sand, which is
approximately 3,000 feet deep in the Carrizo-Wilcox Aquifer group. The temperature of the water as pumped
from underground is 1180 Fahrenheit. To reduce the temperature, the water is routed through cooling towers
at the Sandy Point Pump Station, lowering the temperature to about 850 Fahrenheit.
The groundwater is then pumped through a 30-inch transmission line to the Dowling Road Pump Station.
Prior to entering the 3 and 5 million gallon ground storage tanks at Dowling Road, chlorine is added for
disinfection. The treated drinking water is pumped into the distribution system, which includes two elevated
storage tanks. The elevated storage tanks are an active part of the distribution system and add 5 million
gallons of water storage for peak demand periods. This process assures an adequate supply of water
pressure for use in our homes and businesses and provides fire protection for the residents of College
Station.

Attachment 4: Description of Wastewater System
Reference Item IV. A. 3 on Utility Profile
College Station Utilities operates and maintains two wastewater treatment plants: the Carter's Creek
Wastewater Treatment Plant, built in 1956, and the Lick Creek Wastewater Treatment Plant, built in 1995.
Trained operators at both facilities take steps to ensure that the water discharged from the facility meets
stringent discharge requirements, according to State and Federal regulations. Through the wastewater
treatment process, trained operators take a potentially dangerous waste product and transform it into clean
water and a valuable soil amendment.
Most of College Station's wastewater operations occur at the Carter's Creek WWTP, which serves all areas
of College Station north of the Castlegate subdivision (just north of Greens Prairie Road). The Lick Creek
WWTP was expanded in 2002 from its original treatment capacity of 500,000 gallons per day to treat 2
million gallons per day. The expanded Lick Creek WWTP now serves the southern portion of College
Station, from Rock Prairie Road south to the College Station city limits.
