Aquawolf LLC, an infrastructure engineering company with a Del Mar office at 445 Marine View Ave, Suite 130, Del Mar, CA 92014, specializes in power delivery engineering services covering overhead and underground transmission and distribution, substation design, natural gas pipeline engineering, and owner's engineering. Founded in 2019 as a wholly owned subsidiary of Mammoth Energy Partners LLC (NASDAQ: TUSK), Aquawolf grew rapidly from a small initial investment into a firm generating $17.3 million in revenue and $1.8 million in net income by 2024, employing engineers, designers, surveyors, and project managers across its operations. Other engineering consultants maintaining a Del Mar presence include HRH Engineering, reflecting the neighborhood's draw for technical firms seeking a Southern California coastal base. In December 2025, Mammoth Energy completed the sale of all equity interests in Aquawolf to Qualus, LLC for $30.0 million, with Mammoth receiving $23.5 million in cash at closing and an additional $2.5 million held in escrow for post-closing adjustments. Under its new ownership, the firm continues to deliver services ranging from conceptual design and detailed T&D line engineering through construction support, as-built documentation, and project closeout. Aquawolf's engineering teams utilize industry-standard tools including PLS-CADD, PLS-POLE, PLS-TOWER, MFAD, and LPILE, and their designs adhere to General Order 95, the National Electrical Safety Code, and ASCE standards. The Marine View Avenue office sits in a professional park near the intersection with Jimmy Durante Boulevard, close to Del Mar's coastal business district. Down the road, firms like DUCHANCELL ENGINEERING CONSULTING LLC add to Del Mar's concentration of engineering talent available for complex infrastructure projects. The company's owner's engineer services position Aquawolf staff as an extension of the client's internal team, providing technical oversight on utility projects of any scale across Southern California's growing power grid.
