Our staff is comprised of licensed professional engineers and treatment plant operators who can analyze and provide expert opinions on the complete spectrum of Water and Wastewater treatment plant issues.


Water/Wastewater plants serve their communities by providing clean, contaminate free water and safe removal, storage, and treatment of wastewater.  Design, treatment/pretreatment, and implementation are all vital stages in the processing of Water/Wastewater.  If an incident or injury occurs as a result of an error or omission in any of these stages, Consulting Engineers & Scientists, Inc. has a staff of licensed professional engineers and treatment plant operators who can analyze and provide expert opinions on the complete spectrum of water and wastewater treatment plant issues.  We are also experienced in dealing with the administrative, regulatory, and legal issues that arise with these facilities.
