Dye Testing & Dye Flooding
EST has the capability to perform dye testing by pouring a non-toxic dye into downspouts, area drains, window well drains, stairwell drains, and driveway drains. Testing of these sources is performed to detect illicit connections to the sanitary sewer. EST carefully documents any evidence of illicit connections, which are recorded in appropriate field logs.

Senior Program Director, WOOD PLC
For over twenty years, EST has assisted me with various wastewater and stormwater compliance projects. As an extremely busy project manager, I have high standards and expectations for anyone I’m working with, especially when I’m entrusting them with clients I’m responsible for managing. With EST however, I never have to worry as they are always professional, quick to respond, and they take my client’s compliance needs very seriously. I highly recommend their services.

When it comes to sewer pipeline services for municipalities, we always reach out to EST. They provide competitive pricing while meeting our often demanding schedule. More importantly, EST completes quality work and quickly gains the trust of our clients. I would recommend them to anyone who needs sewer pipeline investigation work completed.
Arthur J. Cunningham PE
LSP Director of Engineering – Capaccio Environmental Engineering, Inc.
One of our most important clients needed wastewater sampling performed and each location had its own unique challenges. We knew EST was resourceful, flexible, had a deep bench, and a can-do attitude so we thought of them to help. The entire EST team made this project a great success for us and our client. We would not hesitate to recommend EST for these and other services as we, and our clients, have had very positive experiences working with them.
