Underground Utilities and Systems

DHGI began as an underground utility contractor and has evolved into the heavy civil contractor they are today.  Our crews are well versed in the construction means and methods required in water, sanitary sewer, storm drain, duct bank, underground detention systems, and pump stations to name a few.  Our client base has ranged from all forms of government entities to Fortune 500 manufactures.  To date we have laid over 14 miles of sewer piping ranging in size from 8" to 54".   Our water experience yields roughly 7 miles ranging in size from 8" to 48".  We have successfully contracted and installed over $3,000,000 of turnkey pump station work in the last 3 years.  

What we feel sets us aside from the everyday utility contractor is having the ability to tackle difficult circumstances related to utility construction many contractors shy away from.  We welcome the opportunity to work during a plant shutdown on a 24 hour schedule or be called in when there is a line failure in the middle of the night that must be repaired immediately.  Working in deep, dangerous conditions and dealing with traffic or adjoining properties is a daily task our crews encounter.  We have experience with all types of pipeline conveyance systems from gravity flow, to pressure piping, to siphons and all material types from PVC, to Ductile Iron, to Prestress Concrete Pressure Piping.
