Rowlett Creek Regional Wastewater Treatment Plant Operations Building and Contractor Staging (Service Yard)

Project Overview

NTMWD held a virtual public meeting on January 12, 2021, to discuss revisions to the site plans for the Rowlett Creek Regional Wastewater Treatment Plant. NTMWD is scheduled to present the revised plan to the Planning and Zoning Commission at its February 15, 2021 meeting. Thank you to everyone who attended the virtual meeting. The recording of that meeting and the presentation given during it are below.

2021-01 Rowlett Creek RWWTP Meeting Presentation – Ops2_FINAL


The Rowlett Creek Regional Wastewater Treatment Plant (RWWTP) is a permitted 24 MGD (million gallons per day) average daily flow plant located at 1600 Los Rios Boulevard in Plano. The City of Plano originally constructed the Rowlett Creek RWWTP in 1956 and operated the facility until the North Texas Municipal Water District (NTWMD) acquired it in October of 1975 after the city requested NTMWD take over operations. Since then, NTMWD has made numerous improvements and upgrades to the plant.

The latest improvements NTMWD is planning to make include constructing a new operations building to replace the current one and adding a service yard for contractors to stage equipment needed for construction. Neither of these projects will expand the footprint of the treatment process at this facility. In fact, these two improvements will allow the District to better utilize the treatment process footprint in the future.

As part of an interlocal agreement (ILA) with the City of Plano covering the property NTMWD purchased from the city, the District has two zoning cases before the Plano Planning and Zoning Commission to amend the current zoning. The cases would change the zoning from:

  • Agriculture (A) with a Specific Use Permit No. 4 for Sewage Treatment Plant TO Agriculture (A) with Specific Use Permit for Sewage Treatment Plant and Specific Use Permit for Service Yard.
  • Agriculture (A) TO Neighborhood Office (O-1)

The first bullet point covers the property that the plant itself is on, the new operations building as well as the future service yard. The second bullet point covers the property south of the new operations building which will remain a large treed area to screen the plant site.



The operations building serves as the administrative offices and control room for the plant. The current building was constructed in the mid-1970s using technology and construction codes from that time and does not contain adequate facilities for staff. Currently, staff uses a temporary trailer for restroom, shower and locker facilities as well as breakroom needs. The new building will be 6,000 square feet and contain:

  • Office space;
  • A control room for the plant that utilizes current monitoring and control technologies;
  • Adequate breakroom, restroom, shower and locker facilities;
  • A conference and training room;
  • A small lab (16-ft by 12-ft) where some samples are quickly tested to optimize the treatment process and other samples are prepared for transport to our certified testing lab in Wylie.
  • Structurally hardened area around the control room and an adjacent storage room for employees to go during severe weather such as a tornado; and,
  • Proper HVAC mechanical systems for heating and cooling the building.

Additionally, NTMWD will plant trees around the new building and make other landscape improvements, including a new sidewalk on the property along Los Rios from 14th Street to the north end of the property.





Currently, there is very little space available for contractors to stage material and equipment essential to the projects that keep the plant in operation and in compliance with local, state and federal regulations. The new service yard would be located just south of the new operations building and would be screened from view on Los Rios and 14th Street by existing trees as well as additional trees that will be planted. An 8-foot tall intruder-resistant fence would enclose the entire yard.


  • The interlocal agreement (ILA) signed in 2019 between NTMWD and the City of Plano requires NTMWD to install and maintain an irrigated landscape screen along the entire western and southern property. The landscape screen would use evergreen shrubs to create at least a 6-foot tall screen within two years of installation. NTMWD is required to maintain this landscape screen in health, growing condition.
  • Constructing a 4-foot-wide sidewalk along Los Rios to the intersection of Los Rios Blvd and 14th
  • NTMWD will not expand the plant’s annual average daily treatment capacity beyond the current 24 million gallons per day (MGD).



What type of office would be built?

The operations building is a 6,000 square foot, single-story building that will house the plant’s employee offices, restrooms, locker rooms and showers, meeting room and break room, small process testing lab, and control room. The building will have a traditional office building facade.




What is the size of the current operations building compared to the proposed one?

The current operations building is approximately 3,000 square feet compared to 6,000 square feet for the proposed building. The current and proposed building are both single-story buildings.

Will the new operations building add additional traffic to the plant? 

The proposed improvements will have no impact on current traffic. Construction traffic will vary but it will be temporary.

Where will parking be located at the new building?

Parking for staff will be located behind the building (on the opposite side of the building from Los Rios Boulevard).

How many parking spaces will there be?

There will be approximately 25 parking spaces for staff and visitors.

Will there be an increase in staffing? 

This project will not increase staffing. The proposed building will provide a safe and proper work environment for our current staff, including providing them adequate breakroom, restroom, shower and locker facilities, as well as a safe space to go in the event of severe weather.

Where will the sidewalk you plan to install be located?

The sidewalk will extend from the new Operations Building south along the east side of Los Rios Boulevard and connect to the existing sidewalk on the corner of 14th Street and Los Rios Blvd.

What type of vehicles will use the service yard/What will be placed in the service yard?

The contractor’s equipment including trucks will be parked in the service yard during their workday. This area is not meant for vehicle maintenance or storage. The primary purpose of the service yard is for the temporary storage of construction material and equipment. The area is currently being used for this purpose and is screened by trees. The proposed improvements would add additional tree screening and a solid fence around the service yard.

Will there be barbed wire fencing?

No. Plans call for a metal fence around the administration building. It will not have barbed wire.
