Water district would pay a Fannin County co-op $8.4 million to power the Leonard plant's next expansion, which must reach 210 million gallons a day by 2030

North Texas Municipal Water District directors vote Thursday on a new substation transformer and power loop for the south side of the Leonard Water Treatment Plant. The work came in under half the $17.3 million budget estimate.

The North Texas Municipal Water District is getting ready to grow its newest treatment plant again, and the first step is electricity.

Directors meeting Thursday, Oct. 22, will be asked to approve an agreement paying Fannin County Electric Cooperative up to $8,413,332 to expand the substation at the Leonard Water Treatment Plant and build a new 25-kilovolt overhead power loop around the south half of the site, according to a staff memo posted with the agenda.

Why the plant needs it

The Leonard plant, which treats water from Bois d'Arc Lake, is rated at 86 million gallons a day, and its Phase II expansion will raise that to 152 million, the memo says. Projected demand growth in the district's service area means the plant has to be able to treat 210 million gallons a day no later than fall or winter 2030.

That is the goal of Phase III, which is in preliminary design. The site is planned for an eventual 280 million gallons a day.

The plant is divided by a road. The first two phases sit on the north side, which the co-op already serves. Phase III, a later Phase IV and a new high-service pump station are planned for the south side, which has no permanent power yet.

What the money buys

The memo breaks the cost into three pieces:

  • $3,920,385 for an added transformer and related equipment at the existing substation, which steps 138-kilovolt transmission power down to 25 kilovolts
  • $4,092,312 for the overhead distribution loop
  • $400,635 for the co-op's project management fee

The district's budget estimate for the job was $17,339,000. Under the agreement, any unspent money comes back to the district, and the co-op would bill for any overrun through a change order.

The new south loop will tie into the existing north loop, which the memo says will let operators switch power sources outside the substation and make the plant more resilient in an emergency. The power system is sized for the plant's full 280-million-gallon buildout.

The board meets at 2 p.m. at the district's offices, 501 E. Brown St. in Wylie. The item goes to the board's water committee Wednesday.
