My name is Mark Farrell and I am the owner and operator of Green Hill Engineering.
I specialize in Massachusetts Title 5 septic system design, perc testing and soil evaluations. Over the past 22 years I have designed over 3,000 septic systems encompassing a wide variety of site conditions.
My back ground makes me uniquely qualified in the business. I have an undergraduate degree from University of Massachusetts in Plant and Soil Science and a degree in Environmental Engineering from Worcester Polytechnic Institute.
Most importantly I enjoy my work and approach each job as an opportunity to get the best possible outcome for you, the client. I can provide you with expert representation from start to finish. I can advise you on all aspects of Title 5 and help guide you thru the process of obtaining Title 5 compliance
