Prosper has been adding a chemical to its sewage for about six years to cut down on odor complaints along Wilson Creek, and the Town Council is set to put that spending on a yearlong fixed-price agreement Tuesday, Oct. 13.
Six years of treatment
According to a memo from Public Works Director Carrie Jones, staff treat wastewater that flows to the North Texas Municipal Water District to control the complaints along the creek. Because the need is continuous, staff want an annual agreement with Helix Laboratories, which the memo says is the only supplier of the product the town uses, a magnesium hydroxide suspension sold as HI-Mag pH.
Helix's price letter, dated Oct. 2, quotes $5.33 a gallon delivered for 48,800 gallons in the 2027 budget year, a total of $260,104. The quantity is based on using about 120 gallons a day, plus a 5,000-gallon cushion. The letter says the company has supplied the town since early 2020.
Orders would be placed only as needed at the guaranteed price, which runs through Sept. 30, 2027. The memo says the purchase is exempt from competitive bidding because the product is available from only one source.
