We take mentoring very seriously here at T&H! This week during a lunch break, Senior Project Engineer James Hoyt, P.E. demonstrated to some of our junior engineers how a drowned orifice works as a connection between two adjacent tanks. The goal of the experiment was to prove that as long as the velocity through the connection remained low, the head loss through the connection would be low, and therefore the level in the first tank would not be significantly higher than the level in the second tank. This experiment was completed utilizing paper cups, straws, and chewing gum.

Tata & Howard provided construction administration and resident observation for this water main project in Milford, MA, which we also designed. Construction is being provided by RH White.

Tata & Howard Engineer Molly Coughlin followed safety guidelines while retrieving data loggers from water meters at a site in Marlborough, MA today. Molly has OSHA Confined Space Entry Certification from Umass Amherst. Great job, Molly!

The City of Newton, MA shows an example of why they are updating their water mains. Tata & Howard conducted a water audit for the City that indicated that a significant amount of water loss within the system was due to outdated pipes, like the one shown in this video.

Video shows the usage of a membrane interface probe (MIP) that allows us to get real time data on the presence of solvents or petroleum related compounds. The contractors are using a Geoprobe® to drive in the sensors. The property, located in Framingham, MA, is a former dry cleaning facility that was contaminated with chlorinated volatile organic compounds (CVOCs). We installed sub slab depressurization systems to reduce the concentration of CVOCs in the indoor air, thereby making the building safe for occupancy.
