Safer. Faster. Non-Destructive. 

Daylighting is a term used to describe the uncovering and exposing of underground utilities and pipelines to the daylight, through non-destructive and more environmentally friendly means such as Hydro-Excavation from Delta!

We cut the dirt with high pressure water around underground utilities and vacuum it up, leaving clean, exposed and damage free infrastructure.

Pot holing is the process of digging a test hole to expose underground utilities. This can check the lines vertically and horizontally. Potholes vary in diameter from 6 inches to several feet and can go down 25 feet or more.

This is commonly used for anode installations, to emplace light poles or to check for existing lines prior to mechanical digging.

Trenching is commonly needed for installing pipes, cables, signs, posts and other utilities underground. Using hydro excavation for trenching is the most cost-effective way to either clear an area, or search for a utility line when the location is known or unknown.

These trenches can be large deep boxes to fully expose utilities for repair or replacement; or to Slot trench by digging narrow, shallow trenches.

Delta routinely produces 100-150 linear foot of trench per day (12”W x 36”D).

Cost efficient, safe utility line (inductive, conductive and GPR) locating unknown lines or infrastructure in the ground, prior to mechanical digging, to ensure safe digging and avoid damage to the utilities. We can use hydro excavation to locate lines and even mark them in preparation for future projects, in a safer, more environmentally friendly manner.

This is the process of fully excavating a large area where mechanical digging methods have been restricted, due to the large amount of underground infrastructure. Inside Oil & Gas plants, refineries and stations, Delta can be most effective with our skilled crews and high rates of production to create large sloped boxes and wide openings in the earth to expose the infrastructure for repair/replacement. Delta consistently produces over 25 cubic yards per day, per truck. More when dump and water are on site.

Let us use our top-notch hydro excavation equipment to clean your 60′ deep lift station. Our giant positive displacement blowers will quickly and efficiently clean your tank.

This is when the hydrovac truck cannot get to the area that needs exposed. Delta is able to park the vehicle up to several hundred feet away, connect the longer hoses, and dig away from the truck. This allows Delta to get into places not easily accessible due to powerlines or other obstacles.

Often times our non-toxic mud/water spoils cannot be disposed of on site. Delta partners with customers to find and source local and the most cost effective location to act as approved dump facilities, in order to minimize customer impact during planning.

Delta’s operators are trained and skilled at supporting emergency and disaster response to assist with clean up related to disasters, spills or flooding to remove debris, sludge, sewage or waste.

We are routinely called on to assist Pipeline Operators in conducting their integrity maintenance programs of owned pipeline, by exposing the utilities for safe testing of their infrastructure.
