Drnach Environmental, Inc. was founded out of an obvious need for Quality flow metering in Southwestern Pennsylvania.  The terrain, hydrology, and age of Southwestern Pennsylvania infrastructure has created a need for sanitary sewer system and combined-sewer system overflow monitoring, and  inflow, infiltration, and CSO studies.  The need for Quality flow monitoring has also driven Drnach Environmental's development of training programs for its employees and municipal employees in the areas of flow meter care, calibration, installation, and reporting.  Drnach Environmental has developed extensive and thorough quality assurance and reporting programs which include both field and office evaluation of real-time and historical flow data, along with hydraulic profiles of specific monitoring points.

Drnach Environmental has, in the past 10 years, completed work for 50 Southwestern Pennsylvania communities and roughly 20 engineering firms, all of whom may be contacted for specific reference to the nature and quality of our work.
