One of our areas of specialization in the environmental engineering field is conveyance and pumping of wastewater and stormwater, as either combined sewer or separate sanitary and stormwater systems. Our experience includes a wide range of projects, from monitoring, studing (I/I, SSES), analyzing (water quality), and permitting and extension and/or reinforcement of existing collection systems, to complete plan developments such as CSSOPs or LTCPs, design, and construction supervision of new multimillion dollar sewerage and stormwater systems. In recent years, we have planned and designed more than 400 miles of sanitary sewer and pressure mains with sizes up to 180 inches in diameter.
For more than 70 years we have provided stormwater management services for flood control and, more recently, nonpoint source pollution control, database management, and administration. We also complete our services with an understanding of future CMOM regulations and their impact on owners’ operations. Our expertise in this field is exemplified by our continuous ranking among ENR’s list of top engineering firms; we are currently ranked 21st based on revenues from sewer projects.
