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 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 will tie into existing infrastructure and treat stormwater for both pathogens and nitrogen. Based on technical feasibility and total cost, one of these communities will be selected to move forward with construction of the BMP. The goal of this project is to develop a stormwater BMP that can be shared with other New England communities.


Sand and Gravel Mines – Ensure Your Environmental Compliance

A mine in northern New Hampshire faced fines of up to $532,500 for violations of the Clean Water Act and the Oil Pollution Prevention Regulations (click here). Sand and Gravel Mines are subject to several Federal and State regulations aimed at preventing pollution, and it is your responsibility to know and be in compliance with them. Requirements for the discharge of process waters, stormwater, dewatering water can be confusing, and meeting water quality limits for turbidity, total suspended solids, pH, etc., in these discharges can be complex.
