Transaction Summary
Calder Capital, a nationwide mergers and acquisitions advisory firm, is proud to announce the successful acquisition of Full Circle Environmental of Garner, North Carolina, by AQUALIS of Morrisville, North Carolina.
The Acquisition Story
Founded in 2001, AQUALIS provides stormwater and wastewater engineering, compliance, and management services to clients nationwide. Its services include inspections, preventive maintenance, corrective repairs, infrastructure rehabilitation, water testing, and emergency response. With a growth strategy centered on acquiring complementary water services businesses, Erin Grenz, AQUALIS’s Chief Development Officer, engaged Calder Capital’s Buy-Side team to identify acquisition opportunities that would expand its capabilities and geographic reach while supporting the acquired companies’ employees and long-term growth.
AQUALIS’s engagement led to Calder Capital sourcing Full Circle Environmental.
Founded in 2017, Full Circle Environmental provides septic and wastewater services to residential and commercial customers in North Carolina, with expertise in complex engineered installations, system design, pumping, and repairs. The company aligned with several of AQUALIS’s acquisition criteria, including its North Carolina location, water services focus, and established management team.
Grenz stated, “Full Circle Septic’s customer-oriented approach aligns with AQUALIS’s purpose to provide sustainable water compliance and management solutions for the betterment of our nation’s communities and corporations. This acquisition strengthens AQUALIS’s presence in North Carolina through the addition of septic capabilities as we move to enter the HOA market, as well as further service our existing portfolio by providing a more complete, full-lifecycle solution for their water infrastructure needs.”

Calder Capital’s Transaction Team and Sale Process
Hannah Nabhan of Calder Capital served as the Lead Mergers & Acquisitions Director to AQUALIS. Serving as Senior Associate was Logan Theodorou of Calder Capital.
Calder’s Buy-Side team generated 44 off-market seller introductions, leading to 22 client pursuits, and one offer made, resulting in the successful acquisition of Full Circle Environmental. Calder Capital introduced AQUALIS to Full Circle Environmental one month into the start of the engagement. The Letter of Intent between AQUALIS and Full Circle Environmental was executed in June and the deal closed four months later.
Grenz noted, “Calder Capital continues to provide an exceptional partnership to AQUALIS. Our deal team, consisting of Hannah Nabhan and Logan Theodorou, continue to source promising opportunities, and we were excited to get this opportunity closed.”
Nabhan shared, “We appreciate Erin’s leadership, partnership, and commitment to the opportunity. Erin, and AQUALIS, had a clear acquisition strategy: identify businesses that provide water compliance services, wastewater engineering, and stormwater engineering services in various geographies across the Southern United States. Full Circle Environmental rose to the top as a compelling fit; we were happy to source them and introduce them to AQUALIS one month into our engagement. We’re excited to continue to help AQUALIS through additional add-ons!”
Sam Scharich, Calder’s Buy-Side Managing Director, mentioned, “AQUALIS’s decision to re-engage Calder Capital for an ongoing, multi-acquisition search is a meaningful vote of confidence in our Buy-Side team. We’re proud to support their long-term growth through environmental services acquisitions and look forward to building on this relationship. Congratulations to Erin, Zach, and both companies’ teams, and thank you to Hannah and Logan for making lasting client partnerships like this possible!”
