Leading the efforts to reimagine community water services is the Florida Department of Environmental Protection. The organization is encouraging communities to expand their water service to incorporate reclaimed water systems for irrigation, industrial processes, and other nonpotable applications. By using reclaimed water for these purposes, municipalities can reduce the demand for potable water and help conserve drinking water resources.
Deland, Florida, is among the many communities around the Orlando area expanding their use of reclaimed water. Over the last several years, the city installed new reclaimed water transmission mains to transport nonpotable water from the Deland Water Reclamation Facility to various locations throughout the city.
B&B Underground and Drilling, Inc. is the local contractor working on the project. In the latest phase of this multiyear project, the company was responsible for installing approximately 3,000 feet of 18-inch HDPE mainline pipe to support a newly constructed pump station.
“Back then, drills didn’t have a seat, and there were no rod loaders or automatic grease buckets. The operator did it all,” Glenn said.

Lee was a salesperson for the turf equipment industry at the time. The two started talking about building a business together. From there, the dream was born. The brothers’ first order of business was getting their own drill. Even though Glenn was already experienced working midsize to maxi-rig-size drills, the two started small and invested in a used Vermeer D7x11 HDD. They got to work installing fiber, coax cable, and electrical lines.
“Our first major project was for the city of Maitland, Florida,” Lee said. “We used the D7x11 drill to help underground a lot of residential power lines. We started small and saved so we could someday get into larger-diameter work.”
“The income we earned was reinvested in the business, leading us to buy our first brand-new rig, a Vermeer D24x40 HDD,” Lee said. “This machine helped us land more water installation projects. At the time, we relied on prime contractors for power and phone work, but we started to advertise more and bid on water projects. As a result, we purchased a new D24x40 Series II HDD. Later, we upgraded our smaller drill to a D20x22 Series II HDD for smaller-diameter installation work. Eventually, we traded that machine for a D24x40 S3 HDD as the bulk of our work shifted to larger-diameter utilities.”
Their workload was rapidly increasing, so the brothers decided to invest in a D40x55 S3 HDD. This allowed them to perform longer shots and install larger-diameter water and sewer lines. By acquiring this machine, they were given more opportunities for mainline water and sewer projects. Consequently, they added a Vermeer D60x90 S3 HDD to their fleet.
Today, B&B Underground and Drilling operates four Vermeer utility drills ranging from a Vermeer D10x15 S3 HDD up to the D60x90 S3 and performs bores ranging from 1 inch to 30 inches in diameter. To help with slurry management, B&B Underground and Drilling uses Vermeer CS 1273 GT and CS 873 GT Trailer Vacs and a custom-built truck vac to support their three crews.
The brothers used their D60x90 to complete the work because it could handle the distances they were boring and was efficient at opening the holes to the required diameters. The bores ranged between 10 feet and 15 feet deep. Two reamer passes were performed after the pilot bore. They prereamed to 16 inches on the first pass and then stepped up to 22 inches while pulling the pipe into place. The team used a McElroy MegaMc 824 Fusion Machine to fuse the HDPE pipe.
During the bore, B&B Underground and Drilling used a combination of bentonite and other drilling fluid additives to help maintain hole integrity in the area’s sandy soil conditions. Lee said working around Florida can be challenging because they have to regularly adjust their drilling fluid formula based on ground conditions throughout their working areas.
“Most of it is sand, but there are parts of Florida where we have to deal with rock, too,” Lee said. “Whenever reaming is involved, we need to put a lot of thought into the strength and quality of the drilling fluid mixture. It’s also important to use a drill that will help us minimize the number of reamer passes made. Anytime we don’t have pipe in the ground, there is potential for the hole to begin to close. So when we ream, we don’t stop until the pipe is in the ground.”
The Deland reclaimed water project took the team at B&B Underground and Drilling a little over a month to complete and involved some narrow rights-of-way and sandy soils.
While many HDD companies perform strictly small-diameter fiber work, companies focused on larger water and sewer utility work are more of a specialty. And building a team up for the task can be more challenging, too. That is why B&B Underground and Drilling emphasizes the importance of training.
“We’ve been around long enough to know that untrained help is bad for business, hard on equipment, and hurts the HDD industry,” Lee said. “We make sure our people are properly trained for the work they are going to be doing, and we often work with the team at [B&B Underground and Drilling’s Vermeer dealer] Vermeer Southeast to support those efforts. They have helped us train equipment operators, locators, and mud specialists.”
Glenn added that with all the advances made in drilling technology since he started, having a good dealer partner that prioritizes training has helped him stay current on the latest technology.
“More and more customers are asking for as-built information, so we recently started using Vermeer Projects bore planning tools,” he said. “The Vermeer Southeast team has helped us work through the learning process. Their support helps keep us at the top of our profession.”
“There are so many communities expanding around the area, and new water and sewer services are needed to support the growing population,” Lee said. “In addition, many municipalities keep a watchful eye on communities that are actively installing reclaimed water systems. With so much attention on water usage, there will be a lot of work to come in this area as well. We are looking forward to doing our part on these projects.”
