CDG’s ability to employ in-house services and resources allows our professionals to seamlessly integrate into our clients’ team to provide more than engineering. This capability combined with an in-depth understanding of treatment technologies, operational issues and regulatory matters affecting wastewater systems provides our clients with the support to guide their projects from concept to completion.
