Hilo Utility Locating Projects That Penhall Has Worked On

Underground utility locating before tree removal

Penhall Technologies was recently contacted by a homeowner to do some private utility locating services.The client explained that his property had a huge tree stump that he wanted to have removed safely. The tree stump was in an area of the yard that had electrical and water lines running through it. The analyst carried two types of utility locating equipment. These were the RD 7100 wand with the frequency transmitter, and the cart with a 400MHz antenna with the GSSI 4000 operating system. The tree stump had large running roots which made it difficult to use the cart. However, the analyst was still able to successfully locate an electrical line and two water lines, one of which ran directly under the stump using the RD 7100 wand. The analyst properly marked the utilities. The client cut the lines safely and capped prior to excavation of the stump.

Penhall Technologies locates underground storage tanks

Penhall Technologies was recently hired to locate some underground storage tanks or USTs for a business owner in the Hilo area. The location consisted of a storage lot that stored heavy equipment. The client instructed our analysts to trace the fuel lines and find the USTs. Also, the customer wanted to know the rough dimensions of the tanks. The analysts used an RD 7100 wand, as well as a 400MHz antennae running under the GSSIs 4000 operating system. The equipment used is very effective when trying to locate underground storage tanks. Our analysts located the USTs  and marked their dimensions, which were roughly 5’ by 12’, 20’ from the location of the old pumps. The analysts were also able to clearly mark the lines running from the USTs back to the old pump stations. Then, they generated a report for the client.
