Washington DC Utility Locating Projects that Penhall Worked On
1. Penhall Technologies reveals man holes that were previously unknown to help customer find out issues regarding their water supply
Last week, Penhall Technologies Maryland colleagues were given an address for a utility locating job in Washington, D.C. When the team arrived at the address, the client instructed them to drive up and park on the National Mall. The client explained that recently the water supply to one of the concession stands on the Mall was turned off or blocked. They had hired numerous companies to come out and investigate, but they could still not figure out what was causing the water to be shut off or blocked. The analysts’ job, was to locate the water line and map out the different directions it was heading. The purpose of this was so that the client knew the direction of the possible blockage or so that they knew where to dig up the line to inspect for damage. The section of the mall the team was asked to map out was about the size of a football field. The SIR 4000 with a 400MHz antenna was used to scan this area. Using spray paint, the analysts accurately marked out the water line in numerous directions and were able to verify our results because the lines led to numerous manholes with water line markings. These manholes were not previously known to the clients. Penhall Technologies of the Washington, D.C. area has the capability and the man power to meet your needs in a timely manner, ultimately ensuring your projects get finished safely and on time.
