NSF Certified Pond Liners

NSF Certified Pond Liners | Potable Water, Fish and Plant Safe

There are many advantages to choosing NSF certified pond liners, especially in applications that require potable or need to be fish and plant safe. Not all liners hold this certification, which guarantees that the product meets all of the regulatory requirements of the U.S. and Canada and is safe for use in drinking water. However, BTL offers several pond liners that are NSF certified for use in drinking water and as fish and plant safe.

Qualifications for NSF Certified Pond Liners

In order for pond liners and other water system components to qualify for the NSF certification, the products must undergo the certification process, which includes:

  • Providing product formulation, toxicology and use information
  • A review by the toxicology  department of the NSF
  • Plant audit and sample collection
  • Laboratory testing
  • Final toxicology evaluation

After completing the process, compliant products are granted the NSF certification. In the case of BTL Liners, providing NSF certified pond liners for our customers allows us to assure that our products are safe for use in drinking water.

Fish and Plant Safe Pond Liners

Choosing fish and plant safe pond liners is essential for the life of these natural elements within your pond, as well as the environment. Unlike certain liner materials, like PVC for example, the RPE and RPP liners from BTL don’t release any plasticizers into the water and there are no harmful byproducts.

Plant and fish safe pond liners have many applications, including:

  • Aquaculture
  • Aquaponics
  • Residential and Commercial Koi Ponds
  • Natural Swimming Pools
  • Irrigation Ponds
  • Water Gardens and Decorative Ponds

From commercial to residential applications, it’s important to choose fish and plant safe pond liners. Since fish and plant safe pond liners don’t release harmful byproducts, it contributes to their position as an environmentally friendly product.

  1. I’m looking for a food safe liner for an aquaculture tank. Your nsf liners sound like they may work. I’m looking for something in the 12’x20′ size to line a tank. Do you have something available that will work? What would be the cost plus shipping to 77328?

  2. Hello,
    I am interested in Food Safe liners. While many of the articles on this site mention the use of RPE and RPP technologies to accomplish NSF rating, none of the descriptions in the actual Shopping section mentions NSF ratings or RPE or RPP manufacturing methods. Can you please provide a list of the BTL Liners that are NSF?

    Thank you.

  3. I would like to get information on:
    1. Whether it can be used for potable drinking water tanks.
    2 Is it safe to store water for longer periods, say 6 months
    2 Do you have dealers in India

    Regards

  4. Hi, I have been desperately trying to find a safe liner to waterproof the inside of a permanent structural planter box (with drainage) that is outside and that I will use to grow food, essentially organically. I had it built into my deck thinking it would be an easy matter to buy food safe black plastic sheeting as liner. Mannnnnnnnnnnnnnnnnnnn was I wrong !!!! You would think that gardening nurseries would have an easy answer and a Go-to material for this kind of simple , homeowner application! They only seem to be focused on natural grow beds built into the earth and that can use landscape and planter fabric that drains and would also allow anything behind/under it to leach in. So better not be plywood or treated wood!!! The only other applications I can find and be certain about are the aquaculture or aquaponic white FDA approved vinyl skrim material, or LLPDE or HPDE (less than 20 mil so it is flexible) sheeting sold by plastics companies. But they only seem to contemplate entire farms or commercial set ups and minimum orders would be around 500 or 600 square feet or a minimum $500 custom order. I really only need about 100 sq feet, and it has to be able to easily mold into corners and up and around vertical sections of a wooden box. Someone else did suggest pond liner as something I can buy in lesser volume, but I wasn’t sure how to confirm “food safe” versus fish safe. I also thought most pond liner was too thick to mold smoothly into corners of a box. Would your material work, what is the thinnest gauge, and can you help ??

  5. I have to ask…
    What is the point of having a section of your website titled ” Responses to questions “. The only information here is the original question. The response is always, “I have answered you by email. ”
    Not very enlightening for anyone reading this hoping for more information as to questions asked…

  6. I will be more than happy to reply on the specific question. The majority of time there are other factors that go into play with their questions, that it’s just easier to email direct… I appreciate your feedback and will start replying directly to comment unless necessary to just send them an email direct!

  8. Hello,
    I am also investigating pond liners for a mostly-organic aquaponics greenhouse/garden. I’d like to put in a 220 gallon pond, and line it with the NSF 61 certified liner. From what I am seeing, though, I will need to dig a hole, then line it with the plastic…? What is my best bet for creating a pleasant pond, that I can filter for my greenhouse?
    Thank you!

  9. Hi Shelly,
    You will need to dig a hole for the pond. The size and shape are up to you and how you want it to look in your location. Once it is dug, you will need to have it measured. Best option is with a flexible tape measure, start approx 2′ up from the water level and measure your longest length and widest width allowing the tape to drape across the bottom of the hole (accounting for the depth) With those two measurements, that is size of the liner you will need for your pond (at the top of our website is a YouTube link with a short video on how to measure your pond). Depending on the sub-grade (soil) would base what liner you would want to choose. Please feel free to give us a call to discuss your project!

  10. Hello,
    I have questions about two different applications of liners:

    Here is application one:
    I am looking to line some older galvanized open top tanks that I use for maple sap storage. Stainless steel tanks are expensive but the industry is moving away from galvanized tanks so i thought i might try plastic lining first.
    My main concern is that any liner that I use does not cause a plastic taste at all (even if it is non-harmful to humans). This is especially important in this particular applications because sap is concentrated from 42 gallons down to make 1 gallon of maple syrup, so if there was a tiny bit of off-taste to start with, I fear it would be amplified by the concentration process.

    I think I would be somewhere around the 20 mil requirement +/- a few mil but that’s just a guess.
    What are your products made of (L/HDPE, PVC, etc.)?
    What would be the cost per ft2 + shipping to 05660?

    Also, the shape of these containers are essentially a hollow cylinder cut in half (the long way) and will be filled and emptied many times in a season. Two points here are that there may be some movement or rubbing from the fill/empty cycle (again, how thick should I go?) and, the material needs to be flexible enough to fit this container with different angles, meaning what material type and again, thickness.

    I would prefer not to get into custom fabricated liners, though that would be simpler to install, I’m going for least cost option for this season.

    Application two:

    I am making my own hot water storage tank for a wood fired boiler to store heat energy in to heat my house. It’ll be around 1,000 gallons of storage. It will be a closed top (but not pressurized), in a basement and so it will never see the light of day (don’t care much about UV resistance). This also is not a drinking water source of any kind, so my main concern is high temperature tolerance. My guess is water would not be over 180/190 F but it could be at the temp for 15+ hours at a time.

    Thanks for your time and help,
