Roswell, New Mexico, is a mid-sized city in Chaves County with a population of approximately 48,000. The local economy is driven by agriculture, aerospace (including the Roswell International Air Center and the New Mexico Institute of Mining and Technology’s nearby facilities), healthcare, and tourism tied to the UFO/alien-related attractions. The water infrastructure in Roswell relies heavily on the Ogallala Aquifer and the Pecos River, and the city operates a municipal water system that serves residential, commercial, and industrial properties. State regulations require annual backflow prevention testing for many commercial and multi-family properties, as well as for irrigation systems that are connected to the public water supply. This creates a steady, recurring demand for certified backflow testers.
The competitive landscape in Roswell is moderate. There are a handful of established plumbing companies and specialized backflow testing providers, but many property managers, homeowners’ associations, and small businesses still struggle to find prompt, reliable testing services. The market also includes clients from surrounding rural areas like Carlsbad, Artesia, and Hobbs, though the focus of this guide is on Roswell itself. Because backflow testing is a mandated annual requirement in New Mexico, the demand is consistent year-round, with a slight increase in spring and summer when irrigation systems are activated. Starting a dedicated backflow testing business in Roswell gives you the opportunity to serve a niche that larger plumbers often deprioritize. With proper licensing and a focused local SEO strategy, you can quickly become the go-to tester in the area.
To legally perform backflow testing in New Mexico, you must hold a valid Backflow Prevention Assembly Tester (BPAT) certification issued by a state-approved training provider. The New Mexico Environment Department (NMED) oversees the program. You must complete a hands-on training course (typically 3–5 days) and pass a written and practical exam. Certification must be renewed every three years, with continuing education requirements. Approved training providers include the American Backflow Prevention Association (ABPA) and various technical colleges. Many courses are available online for the classroom portion, but the practical test must be done in person — often offered in Albuquerque or Las Cruces.
You must register your business with the City of Roswell. The City Clerk’s Office handles general business licenses. As of 2025, the fee is about $50–$100 per year. You will need to provide your EIN (Employer Identification Number) from the IRS, proof of liability insurance (at least $1 million general liability is standard), and your NMED tester certification. The city may also require a local business address (a P.O. box is acceptable for billing, but you need a physical address for service).
Backflow testing services are subject to New Mexico Gross Receipts Tax (GRT). You must register with the New Mexico Taxation and Revenue Department (TRD) to obtain a CRS Identification Number. The current GRT rate in Roswell (Chaves County) is approximately 7.9375% (as of 2025). You will need to file monthly or quarterly returns. Also, note that the City of Roswell imposes its own municipal gross receipts tax, which is included in the overall rate.
Most clients — especially property management companies and municipalities — require you to carry general liability insurance (minimum $1 million per occurrence) and workers’ compensation insurance if you have employees. Errors and omissions insurance is also recommended to cover any testing mistakes that lead to water damage or contamination claims.
