Goodwin & Marshall, a Water and Wastewater Engineering Firm

Utility design plays a critical role in land development.

It’s not just about maximizing your potential above ground, but also about minimizing your impact and expenditures below ground.

What We Do ​

We can design and plan an integrated system that supports the sustainable management of water. From preliminary master planning of regional systems, to the design of transmission mains, lift stations, and booster pump stations, we provide the water and wastewater engineering services and systems you need. Our work includes:

  • Conducting cost-benefit analyses for the construction of water supply systems, runoff collection networks, water and wastewater treatment plants, or wastewater collection systems.
  • Designing or choosing equipment for wastewater processing, keeping your project in-line with governmental regulations.
    Using software tools to perform hydrological analysis.
  • Designing water intake structures, reclaimed water storage, water distribution systems, and more.
  • Analyzing the efficiency of water systems.

From Our Portfolio

Rock Creek Ranch

Fort Worth, Texas

The Chisholm Trail Parkway corridor in southwest Fort Worth is an emerging area of development in DFW. The SH121/Chisholm Trail Parkway toll road opened to traffic in 2014 and allowed for a surge of new development with the new access route. G&M was hired to design the initial infrastructure for Rock Creek Ranch which is a 1,750 acre development located southeast of Benbrook Lake and bisected by Chisholm Trail Parkway.

The development is zoned for single-family residential, multi-family residential, commercial, and mixed-use. The initial phase of the project included the new south Fort Worth campus for Tarleton State University. With no source of adequate water distribution or sanitary sewer collection infrastructure, extensive improvements were required to serve the development. G&M designed 2.3 miles of 12”-24” water line, 2.0 miles of 36” sanitary sewer line, 2.5 miles of thoroughfare roadway improvements, a $1.6 million dollar sanitary sewer lift station, and 2.5 miles of 12” sewer force main.

In-house services provided by Goodwin & Marshall included the following:

  • Several miles of off-site water and wastewater infrastructure, including 18”-36” gravity and 18” force main sewer line
  • Lift Station
  • Water and Wastewater System Analysis
