Drnach Environmental, Inc. is an Allegheny County based Business which was incorporated in 1998 for the purpose of providing flow metering services in Southwestern Pennsylvania.  As of 2023, the company has 4 owners and 5 full-time employees.

Drnach Environmental, Inc. was founded out of a growing necessity for Quality flow metering and sampling 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, inflow, infiltration, and CSO studies.  The need for Quality flow monitoring has also driven Drnach Environmental's development of training programs for its own employees as well as 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 field and office evaluation of real-time and historical flow data, along with hydraulic profiles of specific monitoring points.

In the past 25 years, Drnach Environmental has completed work for over 100 Southwestern Pennsylvania communities and roughly 55 engineering firms, all of whom may be contacted for specific reference to the nature and quality of our work.
