Whether you’re operating a healthcare center, data center, industrial plant, or commercial complex, poor water quality and treatment missteps can lead to scale buildup, biological fouling, premature equipment failure, and regulatory violations in your cooling tower, boiler, or closed loop system. The challenge is choosing a provider who understands the complexity of your system, local water quality conditions, and the long-term operational demands of your site.

A skilled water treatment solutions partner will offer more than just equipment — they’ll bring deep expertise in treatment procedures, flow rate management, contaminant control, and system optimization. In this guide, we prepared ten essential questions to ask any prospective water treatment provider. Use them to assess capabilities, protect your money, and build a water systems partnership that delivers reliable performance and peace of mind.

1. What do you know about my facility’s water quality and treatment goals?

Every facility’s water quality profile is different — and so are its risks. A treatment provider should begin with a full analysis of your source water, whether it be municipal supply, well water, or recycled water. That means testing for common contaminants like chlorides, silica, hardness, sulfur, iron, and microbial activity, along with site-specific contaminants that may not be on a standard panel.

Ask if they’ll provide:

• Water tested through local, certified labs
• Water contaminant trend analysis
• Customized system reports that account for seasonal or usage-related fluctuations

Why it matters:

Poor initial assessment leads to misapplied water systems, especially in applications like reverse osmosis, cooling towers, or steam-generating equipment. A reliable partner will build a solution around your actual water problems, not assumptions.

2. How do you tailor water treatment solutions to match flow, pressure, and performance needs?

Water treatment equipment must integrate seamlessly into your operations. That means accounting for everything from maximum flow rate, variable demand cycles, and makeup water quality to pressure conditions and treatment effectiveness at peak loads.

Key things to ask:

• How do you calculate system sizing based on actual water usage?
• Can you support high or fluctuating water flow applications?
• Do you offer scalable designs that evolve with water system expansion?

Why it matters:

Undersized or mismatched systems lead to under-treatment, inefficiency, and early wear. A provider who understands your water system process end-to-end — including how flow interacts with filters, membranes, or softeners — can deliver a solution that lasts.

3. What contaminants will your system remove — and how?

Effective water treatment starts with understanding what you’re targeting. Many systems fail because they use the wrong technology for the wrong contaminants — or apply the right technology without accounting for system reliability or total cost of ownership.

Ask:

• What specific water problems does your system address?
• How do you determine the best removal method — e.g., activated carbon filters, ion exchange, or reverse osmosis?
• What backup protections are in place to ensure we get better water even under variable conditions?

Why it matters:

Treating chlorinated municipal water is very different from removing minerals like calcium with a water softener or disinfecting bacteria in a closed-loop HVAC system. Using the wrong water filtration method or improperly sized media can lead to microbial growth, fouling, or taste and odor issues in potable water systems.

4. How will you help optimize performance across boilers, cooling towers, and closed loop water systems?

Water treatment is not just about protecting water — it’s about protecting the equipment that depends on it. From boilers and heat exchangers to evaporative cooling systems, water quality directly impacts efficiency, maintenance costs, and system longevity.

Ask your provider:

• How does your innovation prevent scaling, corrosion, and biofouling in HVAC and process systems?
• Do you offer site-specific chemical treatment or just off-the-shelf solutions?
• Can you provide system audits to reduce blowdown or improve heat transfer?
• Can you help me maximize water efficiency through technologies such as water softeners?

Why it matters:

Improper treatment causes scale, oxygen pitting, and biofilm — all of which degrade performance, shorten equipment life, and increase repair frequency. These risks are especially critical in systems with heat recovery steam generators (HRSGs) or high-COP chillers.

5. What is the recommended maintenance schedule — and who handles it?

Even the best-designed water system will fail without regular, proactive maintenance. A reliable provider will outline a clear maintenance schedule, specify who’s responsible for each task, and offer responsive support when unexpected issues arise.

Ask:

• How often are service visits scheduled?
• What routine maintenance tasks are performed during visits?
• Do you offer remote monitoring, emergency support, or repair services?

Why it matters:

Neglecting routine maintenance leads to clogged filters, drift in dosing accuracy, membrane fouling, or system downtime. And unclear maintenance roles between provider and facility staff create costly gaps in service.

6. What happens when something breaks — how fast can you respond?

Even with a well-maintained system, failures happen — whether it’s a dosing pump that loses prime, a failing sensor, or a fouled membrane. The real test of your provider isn’t how they perform on day one, but how they respond when your system is under pressure.

Ask:

• What’s your average response time for emergency service?
• Can you provide temporary equipment or system bypass solutions?
• Do you stock spare parts or offer expedited replacements?
• Who will provide installation of new equipment if something breaks?

Why it matters:

Downtime from a failed water treatment component doesn’t just affect water quality — it can halt steam production, shut down cooling loops, or expose your system to contamination. That means real dollars lost, not to mention regulatory or occupant safety risks.

7. What are the total costs involved — and are there any hidden costs I should know about?

The price tag on a water treatment system is just the beginning. True cost includes installation, chemical usage, maintenance tasks, downtime, and disposal of waste materials. It’s important to explore and ask your provider for a clear breakdown of short-term and long-term costs.

Ask:

• What’s included in your pricing — and what’s not?
• Are chemical deliveries, testing, or emergency visits charged separately?
• How do you help me calculate return on investment (ROI) over time?

Why it matters:

Without transparency, you risk running into hidden costs — like expensive replacement filters, reactive maintenance, or non-compliance penalties. You also miss the opportunity to discover and capture long-term savings through water reuse, energy efficiency, or reduced blowdown.

8. How does your system reduce environmental footprint and water waste?

Sustainability isn’t just good practice — it’s becoming a regulatory and operational necessity across the world. Ask your provider how their systems and chemistries support your environmental goals without sacrificing performance.

Ask:

• How does your program minimize chemical consumption and blowdown?
• What steps do you take to reduce water usage and energy waste?
• How are waste materials and spent media disposed of?

Why it matters:

Many water treatment programs use outdated methods that increase water usage, require frequent chemical dosing, or discharge high volumes of contaminated wastewater. These systems are costly to operate — and difficult to justify to regulators or sustainability officers. EAI values sustainability and strives to design solutions with water efficiency that reduce waste and environmental impact.

9. Are your systems certified and fully compliant with local, state, and federal regulations?

From potable water safety to cooling tower discharge permits, compliance is non-negotiable. A strong treatment partner will help you meet — and document — regulatory compliance with confidence.

Ask:

• Are your systems and components certified (e.g., NSF, WQA, FDA)?
• Do your programs comply with ASHRAE 188, state cooling tower rules, and EPA standards?
• Will you provide documentation and testing to support audits?

Why it matters:

Non-compliance can lead to fines, shutdowns, or even health hazards. But compliance is about more than ticking boxes — it’s about designing treatment systems that work reliably, can be validated with data, and are supported by a partner who understands the rules.

10. What kind of training, certifications, and experience does your team bring to the table?

Water treatment success hinges on the people behind the program. You’re not just investing in equipment — you’re trusting technicians and engineers to keep your water in line with desired parameters, your systems protected, and your facility compliant. That means experience, training, and a culture of accountability matter.

Ask:

• Are your service techs certified (e.g., WQA, water operator licenses)?
• How often do they receive continuing education or factory training?
• Can you provide references or customer satisfaction ratings?

Why it matters:

Poorly trained reps can misapply chemicals, fail to identify issues, or miss early warning signs of corrosion, fouling, or membrane failure. Your facility deserves a team that’s invested in your success and shows up with the right knowledge — not guesswork. EAI lends a hand through facility operator support which is a designed training program for your facility teams.
