Texas Underground Utility Line Installation

Water, Sewer, Drainage, Firelines

We specialize in installing underground utility lines for water, sewer, storm drain, fireline systems and electrical conduit.

For the last 25 years, we’ve worked with private developers and contractors, as well as public entities such as San Antonio Water Systems, BexarMet Water, several school districts and government base work.


Damco Utility, Inc is a Texas corporation established in March 1995. We have over 25 years in the underground utility field.

We annually complete combined contracts in the amount of $5 million plus.

We specialize in underground utility lines consisting of the installation of water (mains, valves, hydrants, services), sewer (mains, manholes, on-site plumbing, laterals) and storm drain lines, any size or depth.

With over 25 years in the underground utility field, we have both the skills and experience needed to complete any project awarded in a safe, professional and timely manner.


Safety is always on our minds during every phase of a project—from start to finish.

All Damco Utility personnel are trained in work safety by Bee Safe safety consultants with job site visits.
