Round Rock renews water treatment deal with Georgetown

The contract will remain in effect for five years, unless terminated earlier by either city.

The framework

Georgetown will supply raw water from Lake Georgetown through its existing water rights, while Round Rock will:

• Treat the water at its plant near I-35 and Westinghouse Road
• Deliver it back through an existing interconnect east of I-35

Georgetown City Council approved the agreement at a March 10 meeting.

Round Rock’s water treatment plant has a capacity of about 52 million gallons per day, allowing it to process water beyond its own customer demand.

The renewed agreement continues a similar structure to the previous deal, which had expired.

By the numbers

Round Rock will bill Georgetown monthly based on water delivered:

• Monthly base rate: $3,702
• Usage rate: $2.21 per 1,000 gallons
• Term: five years

“Since 2018, $8.5 million ... that is revenue that we brought into the water utility ... that helps our citizens’ rates,” Thane said.

Officials added that the agreement carries minimal risk because the city can reduce or stop service if needed.

The local impact

The agreement prioritizes Round Rock’s system during high-demand periods.

If the treatment plant reaches 44 million gallons per day for three consecutive days, or if the city enters its drought contingency plan, Georgetown must reduce its usage to no more than 1.5 million gallons per day.

“When we do get in a situation ... drought or emergency, we can cut that back ... we can cut it all the way back if we need to,” Thane said.

For Georgetown, the deal provides ongoing access to treatment capacity without building new infrastructure.

For Round Rock, it offers a way to utilize available capacity while maintaining control over its system during peak conditions.
