What CSL Services does
CSL Services, Inc. is a privately held engineering field services company founded in 1999 and headquartered in Pennsauken, New Jersey. The company specializes in wastewater collection system flow monitoring and condition assessment, serving municipal utilities, sewerage authorities, water pollution control authorities, and engineering consulting firms primarily in the Northeastern and Mid-Atlantic United States, with selected engagements extending into the Southeast and West Coast. CSL positions itself as technology-agnostic, explicitly not affiliated with any particular flow meter manufacturer, and works with equipment from Hach Flow, ADS Environmental Services, Teledyne ISCO, Marsh McBirney, Telog, and Flowav.
The company's core service offerings span consulting, temporary and long-term flow monitoring, flow sampling, condition assessment, data analysis and QA/QC management, and wireless communication integration with web-based data hosting. Notable technical capabilities include in-situ dye dilution testing for flow meter accuracy validation, flow monitoring in pipe diameters up to 210 inches, and Rainfall-Derived Infiltration and Inflow (RDII) studies. The firm has logged over 500,000 meter-days of flow monitoring activity since inception and reports better than 98% uptime on deployed metering systems for long-term clients such as DELCORA and LACSD.
CSL generates revenue through professional services contracts, typically structured as multi-year engagements (3-4 years) with municipal clients for ongoing monitoring, calibration, maintenance, and regulatory reporting. Pricing is not publicly disclosed and is determined on a project-specific basis through direct client consultation. The go-to-market approach is sales-led, driven by direct outreach, industry reputation, conference participation (PWEA, NJWEA), client referrals, and a website with case studies and contact channels. All services are delivered directly to clients through on-site field technicians and engineers; the company maintains no reseller or distributor channels.
