Horner & Shifrin's environmental engineering team brings a variety of engineering experience and expertise to any job. Having worked with numerous municipalities, investor-owned utilities, and private-sector clients, our expertise has evolved, as has the field of sanitary engineering into environmental engineering, encompassing the management of air pollution, solid waste, and hazardous substances; along with drinking water, wastewater, and stormwater.

Horner & Shifrin's design philosophy is to meet or exceed client expectations by providing innovative, comprehensive and cost-effective solutions.

Horner & Shifrin has been an industry leader in developing innovative solutions for the repair and rehabilitation of existing sewer systems, including separation of sanitary sewage and storm drainage from existing combined sewer systems.

Our wastewater engineering group also has considerable experience in designing innovative, cost-effective treatment solutions for smaller companies (including lagoons, sequencing batch reactors, and membrane biofilters).

In addition, this group has been on the forefront of recent advances in wastewater treatment residuals (sludge) handling, processing, and disposal systems. Gravity belt thickeners, belt filter press dewatering, high-rate aerobic digesters, lime pasteurization facilities, and other such systems have been designed by Horner & Shifrin.
