Wastewater Treatment Facility Engineering
EI has designed and managed the construction of numerous industrial wastewater treatment and ancillary facilities, including water/wastewater treatment systems, groundwater treatment systems, pump stations, water reuse/recycling systems, and containment and diversionary structures. Our engineers evaluate production operations in order to incorporate potential manufacturing modifications into designs to ensure that facilities will meet future demands. Additionally, EI provides troubleshooting consultation services for the evaluation of existing wastewater processes and treatment systems. EI’s list of engineering services include:

  • Wastewater stream treatability studies
  • Engineering design for wastewater treatment system/development of specifications
  • Construction management services
  • Wastewater treatment system start-up support and operations & maintenance

Stormwater Management, Spill Control and Pollution Prevention
Between the EPA’s NPDES stormwater regulations, Spill Prevention, Control, and Countermeasure (SPCC) requirements under the Clean Water Act, and the new, all-around emphasis for pollution prevention initiatives, facility management duties for most industries and municipalities have increased. EI has supported its clients in this area by developing management programs that combine the common threads of these programs and simplify the day to day requirements, saving both time and money. Specifically, EI provides a full array of services including:

  • Development of Stormwater Pollution Prevention Plans
  • Design of containment/diversionary structures for stormwater runoff or spill control
  • Establishing training and authority to carry out emergency response actions
  • Evaluation of a worst-case spill event for the design of secondary containment
  • SPCC plan review and certification by one of EI’s professional engineers


As usual, The EI Group did a wonderful job. The technician that was here was very friendly and professional. Thank you so much for a job well done!

How Trouts Stress the Importance of Protecting Our Waters

How Trouts Stress the Importance of Protecting Our Waters

Have you ever wondered why there’s an insignia of a trout stamped on the top of stormwater drains? If you’ve never noticed this, take a look the next time you happen to see one on a sidewalk or in a parking lot. It’s probably not hard to guess the reason when its printed directly on top, but most people are unaware that those drains lead directly to our streams and rivers.
