Functional, Implementable, Cost-Effective Designs & Stormwater Management

Experience counts, especially in Stormwater Engineering, where inexperience can lead to failure. Too much maintenance. Too much expense. CEI is hands-down the leader and most experienced firm in stormwater design and management.

Our years of implementation experience have taught us what works and our continuous improvements serve our clients well. Additionally, CEI has repeatedly been selected to write statewide stormwater management guidance and manuals, and has completed hundreds of stormwater management and NPDES Phase II related projects.

Technical Assistance Funds

EPA has allocated $500,000 in technical assistance funds to develop and implement preliminary stormwater best management practice (BMP) designs in Barnstable and Chatham, Mass. The two Cape Cod communities will help develop and pilot designs including an innovative stormwater BMP that tie into existing infrastructure and treat stormwater for both pathogens and nitrogen. For more information, visit the EPA website.
