City of Mansfield Water Treatment Plant
Existing Well
Supply History
Maxwell Station - Located about four miles southwest from the center of the City
in the Clear Fork drainage basin. The source of supply was derived from a series of seven
active wells located southerly of the station. These wells are known as: Maxwell Station
Wells (2); John Griebling Well; Hershey Well; Castor Well Markley Well; and the
Brumenschenkel Well. The wells discharged into low service force mains which in turn
discharged into a 40,000 gallon wet well at the station. High service pumps took suction
from the wet well and discharged to a six million gallon ground storage reservoir located
on Woodland Road, in the southwest corner of the City.
The report, completed by Gascoigne and Associates, recommended that both the North Main
Street Station and the Hedges Station be abandoned and that further development be
concentrated at the Maxwell site. It was also recommended that the abandoned supplies be
reserved for industrial development within the Rocky Fork Valley. In addition, a 150,000
gallon elevated storage tank was proposed for the Woodland Avenue area to establish a high
pressure zone for this rapidly developing section of the City.
In 1944, the "Treisch Well" was developed, followed in 1947 by the
"Wiles Well". In 1945, a report was prepared for the City by The
Jennings-Lawrence Company recommending that a supplemental surface water supply be
developed utilizing a portion of the Clear Fork Valley as an impounding reservoir. It was
also recommended that a water treatment plant be constructed to treat this supply source,
including the necessary pumping facilities to convey the treated water to the City. It was
planned that this source would supplement the well supply of the Clear Fork Valley, which
had reached the point where additional wells would damage other water users in the Valley.
This project was placed under construction in 1947, with the reservoir being completed in
1949 and the water treatment plant in 1953. An additional clear water reservoir and high
service station, at the water treatment plant site, were planned in 1958 and placed in
operation in 1959. The proposed method of operation was revised to utilize the water
treatment plant at all times to its design capacity, supplementing this source with well
supply when the demand exceeded the plant capacity.
In 1967, as a result of recommendations in a 1965 report, the water treatment plant was
expanded to twice its original nominal design capacity. This improvement was closely
followed by the construction of a duplicate six million gallon ground storage reservoir
adjacent to the original structure on Woodland Road.
Further improvements were made to the water treatment plant in 1969, when the original
rapid sand filters were modernized to be compatible with the new units.
The method of operation remains the same. The water treatment plant is utilized at all
times to its design capacity, supplemented by the well supply if necessary,
Over the years numerous wells have been drilled in quest for adequate water supply for
the City. Many have been abandoned for various reasons and today, ten have been placed
into service as needed. It has not been possible to obtain the latest, up-to-date
information regarding all ten wells, however what information is available is shown in
