I have held a Texas Licensed Irrigator credential for years. Several years ago, I also completed certification as an NDS Preferred Drainage Contractor. Adding that second credential changed how I work, how my clients experience my service, and how my business performs. It also gave me a perspective on irrigation problems and drainage problems that I simply did not have before, because I realized they are almost always the same problem looked at from two different angles.
This is not primarily a business development piece. It is a perspective I share with other contractors in the irrigation and drainage trades because I believe the industry serves clients better when the people doing the work understand both systems and how they interact. But the business case is also real, and I will share that honestly too.
Why Irrigation and Drainage Are the Same Problem
When a homeowner calls me about a drainage issue, the conversation typically starts with something like: “Water pools in my back corner after every rain.” When they call about irrigation, it might be: “I have dead spots in my lawn even though the system runs every day.”
In my experience, these two complaints are frequently caused by the same underlying condition. The irrigation zone that runs on a schedule calibrated for a dry summer is applying water to a back corner that already drains poorly. The soil in that corner stays saturated longer than the rest of the yard, which means it cannot absorb the scheduled irrigation water. The combination of poor drainage and a system that does not account for it creates both a drainage problem and an irrigation problem simultaneously.
When I only had irrigation expertise, I could address the sprinkler side of that equation. I could adjust the zone, reduce the run time, and check the heads. But I was treating the symptom rather than the cause. With drainage knowledge added, I can look at the full picture: the drainage needs to be fixed first, and then the irrigation zone can be calibrated appropriately for a yard that actually drains. The client gets a real solution rather than a band-aid.
The inverse is equally true. A drainage contractor who does not understand irrigation cannot fully evaluate why a drainage system is underperforming if part of the problem is an irrigation system applying too much water to a zone that already has a drainage constraint. The two systems interact constantly on any landscaped property, and understanding only one of them limits how effectively you can solve problems on that property.
What Dual Expertise Does for the Client Relationship
From a client experience standpoint, being able to handle both services fundamentally changes the engagement. When a homeowner works with a single contractor who understands how irrigation and drainage interact, they get recommendations that account for both systems together. The proposal they receive addresses the complete water story on their property, not just the visible symptom they called about.
This is meaningful because most homeowner drainage and irrigation problems are not cleanly separated. A French drain that is correctly sized for the natural drainage conditions on the lot may be undersized when you account for the irrigation load that gets applied to that area in summer. An irrigation schedule that is appropriate for normal soil conditions may be contributing to saturation problems on a zone with impeded drainage. Understanding both systems lets you design solutions that actually hold up across all conditions rather than just the conditions that were visible at the time of the service call.
Practically speaking, it also means fewer callbacks. When you understand the full picture and design a solution that accounts for all the variables, the fix works. When you address only the part of the problem your expertise covers, something else eventually surfaces and the client calls again.
What It Does for the Business
The business case for dual certification is straightforward. Drainage projects are larger in average scope and revenue than most irrigation work. A residential irrigation repair might run a few hundred dollars. A residential drainage installation addressing a real problem runs several thousand. The ability to assess a property, identify both the irrigation and drainage needs, and propose a solution that addresses both produces significantly larger average project values.
Drainage work also has less seasonality than irrigation. Irrigation has a natural spring startup window and a fall winterization window, but outside those periods the demand is more sporadic. Drainage problems are visible year-round and are often more urgent than irrigation issues. Adding drainage capability fills the calendar gaps that irrigation-only businesses experience during shoulder seasons.
The referral dynamic changes as well. A homeowner who trusts you to handle both their irrigation system and their drainage issues talks about you differently to their neighbors. They describe you as the company that actually solved the problem, not just the company that fixed the sprinkler. That reputation is more durable and more referral-generating than either service in isolation.
Getting Started With Drainage Certification
The NDS Preferred Contractor certification is the most accessible entry point for irrigation contractors looking to add formal drainage credentials. NDS runs training sessions covering their product systems, installation best practices, and design principles for both French drain and surface drainage applications. Certification requires completing that training, and certified contractors get access to NDS’s technical support resources and contractor pricing on their product line.
The broader knowledge base required to design and install drainage systems effectively, including grading principles, soil behavior in different conditions, outlet design, sump pump system integration, and how to evaluate a property’s drainage needs, is built through hands-on experience on real projects. The fastest way to build that experience competently is to work alongside an experienced drainage contractor on several projects before leading one independently.
For irrigators specifically, the soil and water behavior knowledge you already have is a strong foundation. You understand how water moves through and across soil, how different soil types behave, and how to evaluate site conditions for water management purposes. That foundation makes the transition to drainage work faster and more intuitive than it would be for someone starting without it.
The Perspective It Creates
Beyond the business case and the practical benefits to clients, holding both credentials gives you a genuinely different perspective on how landscapes function. You start to see every property as a water management system rather than a collection of separate irrigation zones and drainage problem areas. That perspective makes you better at both disciplines independently, because you understand the interactions that someone with narrower expertise misses.
Water is always the fundamental issue in landscape management. The contractor who understands all the ways water behaves on a property is the contractor who can actually solve the problems that property presents.
Frequently Asked Questions
How long does NDS Preferred Contractor certification take?
The NDS training program is typically completed in one to two days. Ongoing certification is maintained through continued product usage and familiarity with NDS systems.
Do I need a separate license to do drainage work in Texas?
Texas does not require a specific license for residential drainage installation work in the same way it requires licensure for irrigation. However, any work that connects to city storm sewer infrastructure may require a permit and adherence to local codes. A licensed irrigator adding drainage services should review local requirements in the municipalities they serve.
Is the market for drainage services as competitive as irrigation in DFW?
Drainage is significantly less competitive than irrigation service in DFW. The number of contractors who do drainage work well is much smaller than the number offering irrigation services, which means well-qualified drainage contractors operate in a less crowded market with stronger pricing power.
