SUBJECT
Consider adoption of an ordinance of the City of Denton, a Texas home-rule municipal corporation,
authorizing the City Manager to execute a contract with Garrison Minerals LLC, for the supply of
magnesium hydroxide, serving as an alkalinity supplement, and the rental of necessary dosing equipment
for the Pecan Creek Water Reclamation Plant; providing for the expenditure of funds therefor; and

option for two (2) additional one (1) year extensions, in the total five (5) year not-to-exceed amount of
$800,000.00).
STRATEGIC ALIGNMENT
This action supports Key Focus Area: Promote Sustainability and the Environment.
INFORMATION/BACKGROUND
In recent months, the Pecan Creek Water Reclamation plant has been contending with consistently low pH
and alkalinity levels. This challenge stems from an increase in ammonia loading, depleting alkalinity during
nitrification, and the introduction of Ferric Chloride for the chemical precipitation of phosphorus, which
also consumes alkalinity. To address this issue effectively, the incorporation of a Magnesium Hydroxide
slurry into the wastewater process has become essential. This addition serves as a crucial alkalinity
supplement, supporting both the nitrification process and the chemical precipitation of phosphorus, ensuring
compliance with the permit issued by the Texas Commission on Environmental Quality (TCEQ).
