Category: Wastewater

Wastewater infrastructure is one of the most demanding set of assets for a municipality.The non-stop operational requirements and its abrasive environment expose these assets to a very heavy workload and thus, wear and tear. Additionally, with the advent of more frequent and heavier storms observed in the recent years, the existing infrastructure is taking a severe toll Each community faces unique challenges. At METCO, we draw from the depth of our experiences to work with the stakeholders to identify their specific issues and help them develop efficient engineering solutions to address their specific issues at hand.

Our experienced personnel have worked with major wastewater treatment plants, CSO facilities, pump stations, storm systems in many parts of the country.
