Sundt Starts Denton Water Reclamation Plant Expansion to Increase Wastewater Capacity

Highlights

• Sundt has begun construction on the Pecan Creek Water Reclamation Plant expansion in Denton, Texas.
• The project includes a new 75-million-gallon-per-day headworks facility.
• A 30-million-gallon-per-day expansion will use membrane bioreactor technology.
• Work also covers ultraviolet disinfection, anaerobic digesters and expanded solids handling.
• Construction is being phased within the existing plant footprint while maintaining current operations.

Growing wastewater demand in Denton, Texas, is driving an expansion of the city's Pecan Creek Water Reclamation Plant, with new treatment infrastructure planned to increase capacity and improve system reliability. Sundt is leading construction on the project, which began with a groundbreaking Sept. 22.

New Treatment Infrastructure

The expansion includes a 75-million-gallon-per-day headworks facility and a 30-million-gallon-per-day treatment buildout using membrane bioreactor technology. The improvements are intended to expand treatment capacity and update plant processes as demand increases.

The construction program also includes ultraviolet disinfection systems, anaerobic digesters and expanded solids handling capabilities. Underground utility work and other site improvements will be incorporated into the existing plant footprint.

Construction Within Existing Operations

Sundt's scope requires construction to be integrated with the existing water reclamation facility. The project is being phased so that current plant operations can continue while the new infrastructure is built.

The approach is significant for owners undertaking upgrades at operating wastewater facilities, where construction sequencing and utility coordination can affect ongoing treatment operations.

Denton's Wastewater Infrastructure Investment

The Pecan Creek expansion adds treatment infrastructure to support Denton's wastewater system as the city and surrounding region continue to grow. The project combines increased processing capacity with new treatment and solids-management systems.

For municipal owners, the project illustrates the construction requirements involved in expanding an active wastewater facility while maintaining existing service. The combination of new headworks, biological treatment, disinfection and solids infrastructure also requires coordination across multiple construction disciplines.

Why It Matters

The expansion will add substantial wastewater treatment capacity and modernize portions of Denton's existing system. For water infrastructure owners and contractors, the project highlights the importance of phased construction, process continuity and integration of new treatment systems within an operating plant.
