ETS was incorporated in 1987 at its first offices at the Advanced Technology Development Center (ATDC) at the Georgia Institute of Technology. The Principals of ETS, G. Edward (Edd) Valentine, Jr. and Charles C. Ross, P.E., have extensive experience and knowledge related to the design and installation of industrial wastewater treatment systems. Both were members of the Research Faculty of the Georgia Tech Research Institute for over thirteen years, where they were involved in environmental research and education. ETS became a graduate member of ATDC in 1995 and moved its offices to  Smyrna, Georgia. Today, ETS is located in Acworth, Georgia, and has a full-time staff of two principals plus eight other design and support staff. ETS prides itself in providing quality, cost-effective environmental systems and services.

  • Sludge Tanks
  • Aeration Systems
  • Lift Station Systems
  • Chemical Metering Pumps
  • Instrumentation
  • Equalization Tanks



We design and build our own control systems which may include PLC, MMI, and SCADA components.



At ETS, we place great emphasis on process design for each component or system we provide. We provide the following services to promote the most efficient processes in wastewater treatment:  

  • Treatability testing. ETS has laboratory facilities to conduct physical/chemical, DAF, aerobic biological, anaerobic biological, and sludge dewatering testing.
  • Process design. ETS can provide process design services for a complete treatment system including process flow diagrams and piping and instrumentation diagrams.
  • System design. ETS can provide additional system design including hydraulic profiles, equipment layout, and building design.
  • System troubleshooting. ETS has the experience with a wide range of treatment processes to evaluate and provide
    solutions for treatment systems experiencing operational issues.
  • Turnkey installation. Many clients and consulting engineers require a single source of supply at a competitive price
    and in a shorter time frame than traditional design-bid-build. ETS has the design, installation, and project management capabilities in addition to component supply avenues to provide a complete, operating system.


We Have The People.

  • Full staff of engineers, designers, and technicians.
  • Our engineering staff includes PEs and licensed wastewater operators.
  • We have both the knowledge and the hands-on experience to make projects successful.
  • We build our own equipment, so we know what works and what doesn’t.
  • ETS systems are manufactured in the USA.
  • We are on the ground with contractors installing systems, so we know how things go together.
  • We look at systems both from an engineer’s point of view as well as an operator’s, so you get equipment and systems
    that work well and can actually be maintained.
