Boyle has provided planning, design, and construction phase services for numerous collection systems, countless lift stations, and hundreds of miles of wastewater force mains.

Collection system projects have included gravity, low pressure, and vacuum sewers. We have extensive experience with the evaluation of alternatives to convert areas currently served with septic tanks to central sewers. Our lift station projects have ranged from the smallest of residential stations to large master stations with capacities up to 50 mgd. The lift stations have used submersible pumps as well as the more complicated wet well/dry well configurations with extended motor/pump shafts. These facilities often employ various ancillary equipment such as variable speed drives, odor control, emergency power, and SCADA.

Sewer pipe does not come much larger than the Boyle-designed 108-inch Bradshaw Interceptor in Sacramento, California. However, we are just as eager to help clients with smaller pipeline projects or ones that involve special circumstances, such as horizontal directional drilling. Our expertise in sewerlines includes rehabilitation as an answer to aging and deteriorated pipe sections. Boyle experts have assessed the conditions of hundreds of miles of sewer pipe and, where necessary, produced designs for rehabilitation with approaches such as sliplining, pipe-bursting, and cured-in-place “lining.” In cases where gravity pipeline is insufficient, our team has considerable experience in designing lift stations to help convey sewage to a treatment facility.
