The Killeen City Council on Tuesday voted 5 to 2 in favor of a proposal that would save the city nearly 500,000 gallons of potable water daily.
Councilmen Steve Harris and Jonathan Okray voted against allowing the city to enter into a reclaimed water supply agreement with Bell County Water Control and Improvement District No. 1 at Tuesday’s regular council meeting.
The city’s proposed plan calls for Stonetree Golf Club to be irrigated by graywater, which is safe for plants but not human consumption.
Jerry Atkinson, general manager of WCID-1, said the water is, however, somewhat treated. Chlorine is added to the water and it is tested to check for bacteria before the chlorine is removed; then the water is sent down the pipe to irrigate the golf course.
By using graywater to irrigate the golf course, 400,000 to 500,000 gallons of potable water, which is being used currently to water the course, would be freed up. It also would save the city nearly 43 cents per 1,000 gallons on treatment costs. That would equate to about $215 per day.
“Over the course of the past two years, city staff and the district have been exploring potential reuse water projects in an attempt to look for more efficient and best uses for the limited resources that we have,” said Scott Osburn, deputy city attorney.
Graywater for watering the golf course would come from the 38th Street sewage treatment plant.
Osburn said the first step toward completion of the project is for the city to enter into an agreement with WCID-1 detailing the outlines of the project for the reuse system, which the council approved.
The project proposal will now go to the state commission on environmental quality for review.
Osburn said the project is estimated to cost $950,000.
