DATE: December 14, 2021
SUBJECT
Consider adoption of an ordinance of the City of Denton, a Texas home-rule municipal corporation,
authorizing the City Manager to execute a contract with Mabak Directional Drilling, Inc., for dry auger bore
directional drilling for Denton Municipal Electric, Water, and Wastewater Departments; providing for the
expenditure of funds therefor; and providing an effective date (CSP 7651 – awarded to Mabak Directional
Drilling, Inc., in the not-to-exceed amount of $5,000,000.00).
INFORMATION/BACKGROUND
Dry Auger boring utilizes an auger contained within a casing. The casing is advanced as the hole is cut, and
spoil is continuously removed by the rotating auger through the length of the casing. The auger does the job
of both removing excavated material and powering the cutting head. This boring technique is known as dry
boring because no water is needed to support the boring process.
This method of trenchless technology is often used for boring beneath roadways, railroads, and streams or
canals. Dry Auger boring is often required by the state or railroad commission depending on the material,
the size of the casing, and what the pipe is transporting. This is primarily due to concerns for future ground
settlement. This boring technique minimizes the possibility of any surface settling over the length of the
run, due to minimal over-cut and casing being installed as it is cut.
There are currently no viable alternatives to this boring method for crossing under Texas state highways
and railroads. Denton Municipal Electric (DME) as well as the City of Denton Water/Wastewater
department both need to use this boring method for installation of underground pipe at locations where
these state facilities must be crossed to maintain continuity of the electric or water/wastewater systems.
DME will be utilizing this method for multiple crossings associated with the TXDOT projects to widen I-
35 and I-35E through Denton.
Estimated annual expenditures for these boring installations are as follows:
Description Electric Water & Wastewater Total
FY 21-22 Boring 1,500,000 200,000 1,700,000
FY 22-23 Boring 1,500,000 200,000 1,700,000
FY 23-24 Boring 1,500,000 100,000 1,600,000
Totals $ 4,500,000 $ 500,000 $ 5,000,000
