North Brazos Wastewater Planning

Current Status

The City of Waco owns approximately 154 acres near Buster Chatham Road as part of its long-range planning for future wastewater capacity. The property was purchased in 2023 and annexed into the Waco city limits in September 2026.

No wastewater treatment facility is currently under design or construction at this location. Annexation does not authorize the design, permitting, funding or construction of a wastewater treatment facility.

The property preserves a potential location should additional wastewater treatment capacity be needed in the future. Development, actual wastewater flows and system capacity will help determine when additional infrastructure may be necessary.

Recent improvements to Waco's existing wastewater system have extended the City's anticipated planning horizon. Based on current conditions, a potential future facility at Buster Chatham Road may not be needed until 2035 or later.

This is a planning estimate, not a construction schedule. The City will continue evaluating conditions as Waco and the surrounding area grow.

Why Is the City Planning for Additional Wastewater Capacity?

In 2019, the City completed a study of the China Spring area sewer basin that identified the need to plan for additional wastewater capacity as the area continues to develop.

Major wastewater infrastructure requires years of planning. Preparing early allows the City to preserve options and make future decisions based on actual system conditions rather than waiting until existing infrastructure reaches capacity.

The City began evaluating potential locations for future wastewater infrastructure in 2020.

Site considerations included topography, proximity to waterways, available acreage, roadway and utility access, impacts on surrounding properties, prevailing winds, opportunities for screening and environmental permitting requirements.

The City purchased approximately 154 acres near Buster Chatham Road in 2023 to preserve a potential location for future wastewater treatment capacity.

How Does the City Determine When Additional Capacity Is Needed?

The schedule for any future facility will be driven largely by development in China Spring and the surrounding area and by actual conditions within Waco's wastewater system.

The City actively monitors the downstream wastewater interceptor using smart-cover technology. This allows staff to monitor system conditions and identify potential capacity concerns.

Staff combines this information with development activity, wastewater flows and regional planning to continually evaluate when additional infrastructure may be needed.

Recent System Improvements

The City recently completed a reroute of the Flat Rock Road wastewater line, a 27-inch sewer line.

That improvement has provided additional flexibility within the existing wastewater system. Based on current conditions, engineering staff estimates that the improvement has likely extended the potential timeline for a Buster Chatham facility by approximately five years.

Current planning indicates a potential facility may not be needed until 2035 or later.

That timeframe could continue to change based on development, wastewater flows, system improvements and capacity monitoring.

Frequently Asked Questions

Why did the City purchase the Buster Chatham Road property?

The City purchased the property to preserve a potential location for future wastewater infrastructure.

Waiting until the existing wastewater system approaches capacity to begin searching for property could limit available sites, increase costs and reduce the City's ability to thoughtfully evaluate alternatives.

Purchasing the property well in advance preserves an option for the future.

Why was the property annexed?

The City already owns the property. Annexation brings City-owned property into Waco's city limits and provides clearer jurisdiction and consistency for zoning and long-range planning.

Annexation does not authorize construction of a wastewater treatment facility.

Has the City decided to build a wastewater treatment plant here?

The property has been preserved as a potential location for future wastewater treatment capacity. However, a facility is not currently under design or construction.

Future development, system capacity, engineering, environmental review, regulatory permitting, funding and City Council decisions will determine whether and when a facility moves forward.

When could a wastewater treatment facility be built?

There is no established construction date.

Previous planning contemplated an earlier timeline. However, recent improvements to the existing wastewater system — including the reroute of the 27-inch Flat Rock Road wastewater line — have provided additional system flexibility.

Based on current conditions, engineering activities are currently anticipating around 2035 or later. The timeline will continue to be evaluated based on actual development and system capacity.

The timeline will continue to be evaluated based on actual development and system capacity.

How will the City know when another facility is needed?

The City actively monitors wastewater system conditions, including the downstream interceptor serving this area, using smart-cover technology.

This monitoring, combined with development trends, wastewater flows and regional planning, helps staff identify capacity needs and determine when additional infrastructure may be necessary.

What would happen before a facility could be built?

A future facility would require multiple steps before construction could occur, potentially including:

Growth & Capacity Monitoring → Engineering Study → Environmental & Technical Evaluation → Public Participation → Regulatory Permitting → Funding & City Council Decisions → Final Design → Potential Construction

The City is currently focused on long-range planning, system monitoring and capacity evaluation.

How could wastewater be treated at a future facility?

No treatment process has been finalized because a facility has not been designed.

Previous planning has considered treatment processes similar to those used at the City's Bull Hide Creek Wastewater Treatment Plant, including biological nutrient removal, filtration and ultraviolet disinfection.

If a future facility moves forward, the City would evaluate treatment technologies available at that time, environmental and regulatory requirements and opportunities for beneficial reuse of treated water.

Could treated water be discharged into the Brazos River?

Previous planning has contemplated the potential discharge of treated effluent to the Brazos River. However, no final treatment or discharge plan has been designed or permitted.

If a future facility moves forward, treatment standards, potential discharge requirements, river conditions, environmental impacts and opportunities for beneficial reuse would be evaluated through engineering and the regulatory permitting process.

How would impacts on the Brazos River and surrounding area be evaluated?

Environmental considerations would be part of future engineering and regulatory review.

The City would evaluate issues including water quality, flood risk, drainage, site resiliency, odor and noise control, traffic, access, screening, buffers and impacts on surrounding properties before a facility could move forward.

What about odor, noise and traffic?

Because a facility has not been designed, final operational impacts are not yet known.

If the project advances, engineering would evaluate odor-control technology, noise, lighting, traffic, roadway access, screening and buffers. Experience at the City's existing wastewater facilities would help inform that evaluation.
