Engineer Evaluation Report (EER)

Ontario Regulation 170/03 – The Drinking Water System Regulation made under the Safe Drinking Water Act covers municipal and private water systems providing water to year-round residential developments and designated facilities that serve vulnerable users. 170/03 mandates strict drinking water system requirements including water treatment and water testing. Drinking water systems require professional Engineering Reports to certify that the water system is in compliance. Our services include the initial water sample collection, analysis by a certified laboratory, interpretation of the results, water treatment system design and supply and installation of the required equipment. The Engineering Evaluation Report is then completed and submitted to the appropriate MOE authority.
