Wylie Water Treatment Plant Operations Center

Project Overview

The District has outgrown the current building constructed in 1956 and designed to oversee operations for delivering water to 32,000 people. Today, NTMWD delivers water to approximately 1.8 million people throughout 80 communities. The new building will provide the additional space required for the modern technology and monitoring systems needed for a regional systems control room. The 14,343-square-foot one-story building will also include more office space, a training room and small space for operators to quickly test water samples to help optimize treatment processes. A portion of the building will be hardened to withstand high winds and airborne debris during a tornado or other major storm event to ensure continuity of operations.

WHAT: The facility is the heart of regional water system operations. From here, operators control:

  • pipelines, pumps, valves and tanks for water coming in from various sources;
  • water flowing between plants and multiple steps of treatment process; and,
  • distribution of treated water to city storage tanks.

WHY: This site was the preferred location of seven evaluated by staff for the following reasons:

  • Security is a critical factor. A building on perimeter allows easy access for operators, public and first responders without compromising plant security.
  • Existing utilities are located nearby (power, water, fiber optic network).

STATUS:  Crews recently completed the roof and are currently doing electrical work on the interior of the building and pouring additional paving outside.

WHEN:  The $11.9 million project is scheduled for completion by the end of 2020.

Being a Good Neighbor

Being a good neighbor is important to NTMWD. We’re designing this building to be visually pleasing and minimize impacts to the immediate area.

  • Landscaping and trees will provide natural screening.
  • Design will demonstrate water efficient landscaping and rain water collection.
  • Downward facing outdoor lighting will be installed to avoid unnecessary light pollution.
  • The building’s emergency generator will be enclosed to meet the city ordinance for noise levels.
  • Visitor and visiting staff parking will be located in the front; work vehicles will park in the back.
  • The building will initially support 30 employees with capacity for 45.
  • Most employees work 8 a.m. to 5 p.m.; About six employees would work overnight.

Water Quality Testing

A small, 600-square-foot lab will be used by water operators to quickly test samples to optimize treatment. The bulk of our daily testing for water and wastewater will continue to be done at the main lab on Brown Street.

There are limited chemicals in small quantities in this lab with no bulk chemical storage. Chemicals are delivered by FedEx/UPS, and most containers are one liter in size. The amount of chemicals kept here is a fraction of what you would find in a hardware or pool supply store.

Road Improvements

The current alignment of Lynda Lane would run between the new water operations center site and the Wylie Water Treatment Plant IV site. Realigning Lynda Lane would eliminate an unsafe intersection and improve plant security and access for NTMWD vehicles operating between the water operations center and the water treatment plants.

An approximately 700-foot extension of Lynda Lane to Forrest Ross Road would be constructed on the north side of the planned water operations center. The current alignment of Lynda Lane on the west side of the planned water operations center would be abandoned. NTMWD would pay 100% of the estimated $650,000 cost of the Lynda Lane project.

Additionally, 860-feet of Eubanks Lane between Highway 78 and the east entrance near Plant IV would be reconstructed in four lanes of reinforced concrete, and a deceleration lane would be added to the westbound lanes of Highway 78. NTMWD would pay 65% of the overall estimated $2 million project cost for Eubanks Lane and the deceleration lane.
