Wastewater Treatment

Reid Engineering Co. (REC) is a well organized team of professional engineers and designers with extensive knowledge in the field wastewater treatment.  More Specifically, REC has been in business for over 36 years specializing in innovative and cost effective wastewater treatment design solutions. While most firms provide wastewater treatment as a secondary service, REC considers wastewater treatment to be their core niche and leading solution offering to clients globally. Many of RECs Clients continually rely on  them over and over again and in various States to provide wastewater treatment solutions.

Currently, REC provides wastewater treatment solutions in the Municipal, Industrial and Federal Sectors. Enhanced and Biological Nutrient Removal wastewater treatment solutions have been a major focus for REC over the past fifteen to twenty years.  REC has many facilities in operation meeting very stringent Total Nitrogen and Total Phosphorus limits within the Chesapeake Bay Watershed and Nationwide.  Please see our Featured Projects for more specific information on some of our Nutrient Removal Facilities.
