Wastewater Solutions



Water is one of our most valuable resources, and is essential to human health, environmental sustainability, economic development, and overall well-being. We are dedicated to cleaning the water of the world, one drop at a time.  We provide planning, permitting, design, construction management, and start-up services for decentralized wastewater treatment systems.

Expertise in Wastewater Treatment and Management

With over 50 years of combined experience, the relationships with our clients are what we value most.

  • Our focus is to deliver our clients the most cost-effective wastewater treatment systems when they don’t have access to a municipal sewer system.   
  • Acquired numerous permit issued by TCEQ throughout Central Texas
  • Completed permitting, design, and construction management of decentralized wastewater treatment facilities throughout the United States including, Texas, New Mexico, Colorado, Arizona, Oregon, Washington, Montana, and Georgia.
  • Acquired multiple Reclaimed Water Authorizations for the beneficial reuse of water to offset the burden on potable water systems.
  • Designed over 50 wastewater treatment facilities using a vast range of treatment processes.

Southstar Communities has worked with Jamie Miller’s team over the past eight years. When we have a development that requires a wastewater solution, we rely on them to get the job done. We’ve been impressed by their ability to obtain regulatory permits in a timely manner.

Jamie Miller

Jamie Miller, PE


Jamie began her career in 1996 as a design engineer. In 2005 she went to work for a construction company that focused on decentralized wastewater. In building an engineering group, she elevated the company to a design-build firm. In 2010 permitting and design in Texas became a key focus. Developing excellent working relationships with the TCEQ, utility districts, and local developers, she has established herself as a decentralized wastewater expert in Texas. With so much travel to Texas, it was fitting that her oldest child graduated from Texas A&M in Electrical Engineering. She is the proud mother of three children.

Bill Ellis

Civil Designer, CAD Manager

Bill began his career as a mechanical drafter, working on the Saturn V Booster at Boeing. He then got involved in the birth of desktop computers at Hewlett Packard where he specialized in Surveying and Civil Engineering products. He learned the coordinate geometry and programming required to produce plot files consisting of points and lines representing reduced survey field data and design data such as points, surfaces, alignments, and profiles which could then be plotted on a large format plotter, accurately and efficiently. The final drafting linework and annotation would be done by hand, in ink on mylar. Then came CAD!

Bill became a Civil CAD Technician in 1987. For the last 25 years, he has been a CAD Designer and CAD Manager using AutoCAD and Civil 3D, working at some of the largest Civil Engineering firms on the West Coast, doing Site Development, Roadway Design, Water and Wastewater System Design, Solid Waste Disposal and more.

For the last 10 years, Bill has worked in a smaller company environment specializing in Water and Wastewater Treatment where he enjoys the teamwork and the knowledge that he is contributing to the welfare of the environment.

Bill lives in Santa Fe, New Mexico, where he likes the clear skies, the local art and architecture, music and the company of his black and white cat.
