Contractor HCCCO.LLC.of Tulsa entered Phase II for the City of Altus water treatment plant improvements this week. The plant was built in 1975 as a mixed media gravity filtration plant with primary clarifiers and chlorine disinfection that is permitted to produce up to 14 million gallons per day.
The purpose of the project is three fold: To rehabilitate and repair the reverse osmosis (RO) treatment facility to restore operation, install piping and valves to prepare the plant to receive well water from the Round Timber and Holloway Wells Fields to be blended with treated water from the plant prior to disinfection and distribution, and to improve existing elements of the conventional treatment plant such as rebuilding pf clarifiers and replacement of filter valves and controls.
In 2005, the Reverse Osmosis (RO) treatment was constructed. RO is state-of-the-art and the best quality treatment, but is more expensive to operate. The RO water was blended with treated water from the conventional filter plant. Due to a key design flaw, the RO plant proved difficult to operate and was taken off-line in 2009. Since then, all drinking water has been treated by mixed media filtration.
City of Altus Public Works Director/City Engineer Johnny Barron said the project will improve water quality and greatly reduce chlorine by-products that have been recent problems. Barron added, “Altus residents may also notice an overall softening effect caused by the reduced amount of minerals in the water. While the process is being completed, there should be no interruption in water services.”
Once the project is finished , the plant will be set up to produce a three-part blend of RO treated water, conventionally treated water, and well water. The RO improvements will be completed first and it is anticipated to return to operation in March 2016.
