SewerAI and RJN Group Announce Strategic Implementation Partnership to Accelerate AI‑Driven Sewer Infrastructure Assessments

Walnut Creek, CA – April 22, 2025 – SewerAI, the global leader in AI and cloud-powered sewer inspection technologies, has entered into a strategic implementation partnership with RJN Group, a 100 % employee‑owned (ESOP) engineering and field‑services firm specializing in water and wastewater infrastructure. This collaboration aims to accelerate the digital transformation of sewer condition assessment and asset management at utilities throughout the US.

The alliance combines SewerAI’s cloud‑native platform—AutoCode™, CodeAssist, Sewer3D™, and PIONEER®—with RJN’s five decades of engineering expertise to deliver faster, more accurate condition assessments and data‑backed capital plans for municipalities and utilities across North America. Together, the organizations will enhance project efficiency, data quality, and actionable insights for municipalities and utilities.

“Utilities need actionable insights, not more video,” said Eric Sullivan, VP of Business Development and NASSCO-Certified PACP™ LACP™ MACP™ Trainer at SewerAI. “RJN’s reputation for quality data collection and data integrity makes them the perfect partner to scale our AI technology and help cities prioritize repairs in days, not months.”

“From day one, our mission has been to eliminate guesswork underground and make wastewater professionals superhuman,” added Billy Gilmartin, Co‑Founder and Co-CEO at SewerAI. “Working shoulder‑to‑shoulder with RJN means the best data science meets the best field science—so communities can stretch every rehabilitation dollar.”

Partnership Highlights

• End‑to‑End Deployment: RJN will embed SewerAI’s platform in inspection, analysis, and reporting workflows, giving clients real‑time assessment deliverables that meet NASSCO PACP and MACP guidelines. 
• Seamless Data Flow: AI-assisted condition assessment by SewerAI enhances RJN’s proprietary Clarity^® Data Management Hub, a single source for intuitive project life cycle management. Clarity enables clients to view, analyze, and manage live hydraulic and condition data through a user-friendly, GIS-based interface.
• Joint Project Pursuit: The firms will target high‑impact rehabilitation projects where AI and engineering expertise together can cut inspection costs and compress project timelines.
• Continuous Innovation: SewerAI and RJN will co‑develop best practices, training programs, and data insights to push the boundaries of sewer‑system intelligence.

“Embedding SewerAI’s AI engine into our workflows facilitates increased assessment efficiency by bolstering our engineers' data analysis capabilities with an AI that we helped train,” said RJN President and CEO Paul Costa. “Our clients have come to expect nothing less than the most innovative data collection and analysis solutions from RJN, and our partnership with SewerAI helps us continue to meet this mandate.”
