Project Charter
BACKGROUND
The Ray Roberts Water Treatment Plant (RRWTP) was constructed and placed into service in 2002, with a
capacity of 20 million gallons per day (MGD). There is a need to expand the treatment capacity at the RRWTP.
With the continued residential, commercial, and industrial growth experienced in the City of Denton, the City
desires to expand the capacity of the RRWTP to approximately 40 MGD through the design and construction
of a parallel membrane process train. The anticipated initial capacity of the membrane process train will be 20
MGD with space reserved for an additional 30 MGD in the future for a total of 50 MGD at full build-out of the
membrane building designed for this Project.
GOALS
1. Increase the level of water treatment capacity to meet the growing demand for water in the City of
Denton.
2. Construction Completion by end of calendar year 2029
3. CMAR Project Success: Document Lessons Learned
4. Leverage the benefits of the CMAR Process to mitigate risks more effectively and to deliver this project
within budget and on schedule.
5. Maintain trust and support from key stakeholders: Denton Water Utilities Water Production

SCOPE
To meet the City of Denton’s growing water demands, the Ray Roberts Water Treatment plant needs to be
expanded. The RRWTP expansion project will double the treatment capacity from 20 MGD to 40 MDG. To
accomplish this, the following components will be included in the project:
• Low-pressure membrane units
• New parallel raw water pipeline
• New pre-ozone contactor
• New pump diffusion vault and flow separator
• New flocculation/sedimentation basins
• New membrane feed pump station
• New intermediate ozone contactor
• Biologically active filters
• New transfer pump station
• An additional clear well
During the design phase, the consultant will be required to perform a pilot study for the low-pressure
membrane filters to comply with the Texas Commission on Environmental Quality (TCEQ) requirements for
innovative treatment technologies. Additionally, the consultant will need to evaluate the existing raw water
supply and flow split, solids handling, and incoming electrical power supply and distribution infrastructure.
CRITICAL SUCCESS FACTORS
1. Selection of the right Construction Manager at Risk.
2. Issuance of a Notice to Proceed for the design by January 2025.
3. Owner collaborative mindset and enforcement of collaborative behaviors with CMAR team.
4. Operational coordination to maintain the level of service needed to safely treat distribute water into the
City’s water distribution system.
