Services
Trinity Engineering provides Civil Engineering design services to a wide array of clients. Whether your project involves Stormwater, Erosion Control, Wastewater, Water Supply, Subdivisions, Retaining Wall or Slope Stability issues, Stream Crossings, Commercial Solar or Floodplain Studies contact Trinity to see what we have to offer.
A water supply system must be designed to provide water of adequate quantity and quality for the proposed use. A water supply system consists of the water source, pumping systems, water storage tank, the transmission or distribution system, and may also require a disinfection or treatment system. Every potable water supply source has a source protection area surrounding it.
A subdivision creates multiple parcels of land from an existing tract of land. Subdivision design is the art of seeing what the land has to offer, working within the applicable laws to design a development that will serve the future owners and the municipality. Designing a subdivision is sometimes very straightforward.
On certain Site Designs, retaining walls are required to provide a safe and stable grade transition. A site design often uses a simple dry laid stone wall to define an area. A simple gravity retaining wall can serve as an attractive way to provide a grade change in a site plan. Improperly designed retaining walls fail by overturning, sliding, settling, or by a global slope failure.
Culvert and bridges must be designed to safely pass the design storm. In addition, they must be designed to comply with stream crossings standards. Proposed crossings must provide for Aquatic Organism Passage, or AOP. As a result, state design standards follow the US Army Corps of Engineers requirements for stream and river continuity.

We decided to sell our house at the beginning of winter which meant it was not possible to have our MA Title IV inspection performed at that time due to frozen ground. A buyer made an offer in the spring and we quickly needed to have the Title IV completed for the sale to take place. A certified inspector performed the inspection and it failed. On very short notice we needed to have a perc test completed, test pits dug, a new septic system designed with stamped prints and the permit filed. If we were not able to complete this it would have meant the loss of a $300K sale. I contacted Trinity Engineering

We asked Trinity Engineering for a soil evaluation and a wastewater system design for our new home. John and his team were amazing! His communication and clarity of what was to be done were outstanding. He responded quickly to questions and provided all of the necessary paperwork for our project. Trinity is very professional all the way around. They exceeded my expectations.

I had just put my house on the market and the septic system failed. I contacted Trinity Engineering and John Dupras and his team put together a plan to get the system legal in a very timely and professional manner. The thing that really impressed me was their going out of their way to keep the cost as reasonable as possible for the situation I was in and their diligence in working with the city of Pittsfield to make sure that my interests were taken care of. They communicate extremely well and I always knew what was going on. I really believe it could have been even worse if not for Trinity!!

I'm a Realtor and needed to help my Seller get a new septic system in before the ground froze. John Dupras and his team at Trinity Engineering were excellent. John communicated in a very timely manner, handled all the new on-line permitting quickly, coordinated with the Health Inspector and even recommended a company that got the system installed within two weeks. We are very pleased with Trinity Engineering's work and would absolutely recommend John and his team. Thank you Trinity Engineering!
