For many homeowners, a pond is a peaceful backyard feature. But in parts of the country like Northwest Ohio, a pond can be far more than just aesthetic—it can serve as a home’s primary water source.
When well water is scarce or high in sulfur, some families turn to ponds to supply their daily water needs. But not just any pond can be safely tapped for drinking water. That’s where professional treatment systems come in.
At Aquatek Water Conditioning, we specialize in designing and installing systems that make pond water cleaner, safer, and fully potable. These systems are carefully engineered, strictly regulated, and uniquely tailored to the specific water quality and health code requirements in our region.
Why Use Pond Water as a Drinking Source?
In certain areas, especially in Northwest Ohio, homeowners may not have access to reliable well water. Some wells produce less than a gallon per minute, while others pull water so high in sulfur or minerals that it’s practically untreatable. In these cases, digging a properly constructed pond and installing a certified treatment system may be the only viable way to access clean water for drinking, cooking, bathing, and everyday use.
This isn’t a luxury upgrade—it’s a necessity for hundreds of families. But using surface water comes with challenges. That water must be treated thoroughly to meet state and county potable water standards, and the system must be installed and maintained by certified professionals.

What Does the Pond Water Treatment Process Involve?
The process of turning pond water into potable water is far more advanced than most people realize. It involves multiple layers of treatment that mimic the structure of a municipal water plant, but scaled down and installed inside your home. These systems are engineered to ensure the final product is safer, clearer, odor-free, and great-tasting. Here’s how it works in detail:
Step 1: Chlorine Injection
Once the water is pulled from the pond, the first line of defense is chlorine. A chlorine solution is injected into the water to kill bacteria, viruses, and other microorganisms. Chlorine remains one of the most reliable disinfectants available, and its use is approved and required by state code. However, it doesn’t act instantly—it needs time to do its job.
Step 2: Alum Injection (Aluminum Sulfate)
At the same point in the line, the system injects alum—a clarifying agent that coagulates fine particles like silt and organic matter. These tiny particles, which are too small to be caught by most filters on their own, clump together after the alum is introduced, forming larger masses that can then be physically removed during filtration.
Step 3: Retention Tanks
To allow the chlorine and alum to work effectively, the water flows into large retention tanks. These tanks provide the critical “contact time” needed for disinfection and coagulation to occur. Skipping this step would render the earlier injections far less effective. The water must dwell in the tanks long enough to ensure that bacteria are killed and particulates are clumped for removal.
Step 4: Sediment Filtration
Once the water exits the retention tanks, it passes through a backwashing sediment filter. This filter traps the now-clumped debris and removes it from the water stream. It’s an essential step for removing physical impurities and protecting the finer filters downstream from clogging prematurely.
Step 5: Carbon Filtration
The next stop is a carbon filter, which removes the chlorine injected earlier. This ensures that the treated water doesn’t have a strong chemical taste or odor. It’s a comfort step—but an important one that gives you cleaner, fresher water you’ll actually enjoy drinking and cooking with.
Step 6: One-Micron Absolute Filtration
As a final safeguard, the water passes through an absolute one-micron filter, designed to catch any remaining cysts or microscopic organisms that may have survived the earlier stages. These cysts may not always be killed by chlorine alone, so this filtration step provides an added layer of protection to ensure nothing unsafe slips through.
Together, these steps create a multi-barrier system that delivers cleaner, safer, and compliant drinking water to every faucet in your home. Optional add-ons, such as UV disinfection and reverse osmosis, can further enhance the water’s quality and reliability based on your needs.
Certification and Compliance: Why It Matters
In Ohio, systems that treat pond water for drinking must meet strict state health codes, and the ponds themselves must also be properly constructed by certified contractors.
If a pond is dug by an uncertified contractor or if it doesn’t meet code specifications for slope, depth, or runoff, a permit for water treatment may be denied, and the homeowner may need to completely redo the pond. We’ve seen it happen, and the cost can be staggering. That’s why we strongly encourage homeowners to contact us early, ideally before excavation begins, so we can help connect you with a qualified excavation contractor and avoid costly setbacks.
Aquatek works closely with local health departments across multiple counties to ensure every design is code-compliant. Before installation begins, we request approval from the health department. After installation, the system and water are tested again to verify that they meet all potable standards.
Why Maintenance Matters (and What It Involves)
Pond water treatment systems are highly effective—but only when maintained regularly. Unlike a water softener, which can usually limp along if ignored, a failed pond water system can result in complete water loss. That’s why routine care is more than a best practice—it’s essential for water safety and system longevity.
Annual Pond Filter Replacement
Every system includes a floating pond intake filter, which plays a crucial role in supplying the pump with clean water. Over time, it can clog with algae or debris. While it can be replaced in winter, doing so under frozen conditions is more difficult and expensive. That’s why we strongly recommend scheduling this service during warmer months to avoid emergency calls and added labor costs.
Yearly Maintenance Checks
Each year, AquaTek conducts a full system inspection to ensure performance and code compliance. We verify chlorine and alum pumps, test flow and pressure, inspect filters, and make adjustments before issues escalate. This preventative approach helps avoid costly failures and service interruptions.
Media Rebedding Every 4–5 Years
Filtration media inside the sediment and carbon tanks degrade over time. We replace this media every 4–5 years to ensure the system continues to perform effectively. Failing to rebed tanks leads to poor water clarity, pressure loss, and potential health risks.
Homeowner Testing Between Visits
We provide each homeowner with a chlorine test kit and instructions. Monthly or quarterly testing confirms your system is working as intended. If anything is off, our team is just a call away for prompt support.
Keeping up with these service intervals protects your investment and ensures your family has continuous access to safe, clean water year-round.
Does the Pond Itself Have to Be Perfect?
One of the biggest misconceptions about pond-sourced water systems is that the pond needs to be pristine. The truth? The pond does not have to look clean for your household water to be clean. Whether your pond is murky, weedy, or crystal clear, it’s the treatment system—not the pond’s appearance—that determines the quality of your water.
While some homeowners choose to maintain their pond for aesthetic purposes, doing so is optional. That said, we do offer FDA-approved pond maintenance products such as dyes and algaecides that are safe for use in ponds that feed potable systems. These products are ideal for anyone who wants a cleaner-looking pond without compromising their water safety.
A pretty pond may be nice, but a reliable, treated system is what truly matters.
The Environmental and Financial Upside
When treated properly, pond water offers both environmental and economic benefits. It reduces dependence on municipal water supplies and avoids the cost of drilling deep or ineffective wells. According to the EPA’s guidance on water reuse, safe use of alternative sources like surface water can contribute to long-term sustainability and resource conservation.
And in areas where ponds are a necessity, maintaining a system that meets code and delivers clean water offers not just peace of mind, but also helps preserve property value, especially during refinancing or home sales, when lenders may require system upgrades.
Frequently Asked Questions About Pond Water Treatment Systems
Can any pond be used for drinking water?
Not without treatment—and not without approval. The pond must be constructed by a certified contractor and meet state health department guidelines. The water itself must be treated with a certified, multi-stage system. Without these steps, the water is not considered safe or compliant for potable use.
Does my pond have to be clean or look good?
No. A pond does not need to look pretty to be used as a water source. Our treatment systems are designed to handle water from murky, algae-filled, or natural-looking ponds and still produce treated water inside the home. Appearance is optional and cosmetic only.
How often do I need to maintain the system?
We recommend annual service visits, pond filter replacement once a year, and rebedding every 4 years. Homeowners should also test chlorine levels monthly or quarterly using a simple test kit. We also encourage homeowners to inspect the lines in the pond to ensure they are not exposed, especially heading into the winter months. Proper maintenance helps prevent system failure and ensures long-term water quality.
What happens if I skip maintenance?
Skipping maintenance can lead to clogged filters, pressure loss, unsafe water, or even a complete loss of water access. Exposed lines in the winter months could lead to freezing, which could result in an extended period of loss of water to the home or barn and costly repairs. Routine service is critical for system performance and your household’s water supply.
How long do pond water treatment systems last?
With proper care, most systems last 20+ years. Many older systems are still functional but may no longer meet current code. We can assess and upgrade existing setups to meet today’s safety and efficiency standards.
Can I dig the pond myself or hire any contractor?
No. The pond must be dug by a state-certified excavation contractor who understands potable water regulations. Improper construction may result in denied permits and expensive rework. Contact us early, and we’ll help connect you with a qualified pond builder.
