Above-Ground Poly Tank Installation

Poly Tank Sitting Information

Correct Method for Sitting an Above Ground Poly Tank:

  1. Your Duraplas tank can be sited on LEVEL STABLE GROUND which has UNIFORM COMPACTION [free of soft spots] with a screeding of approx 75-100mm of sand or metal dust [approx 3mm stone]. The fill must be retained using some form of retaining structure eg [cement strip, rocks or treated pine sleepers etc ].above-ground-water-tank-installation-diagram
  2. Alternatively your Duraplas tank can be sited on a reinforced concrete slab which must be 25mpa [approx 75-100mm thick with F72 mesh] that is level, flat and larger than the base of the tank. Consult an engineer for slab details.

Correct Method for Sitting Tank Half Way in Ground:

  1. Prepare hole. Ensure that the surrounding soil left in the walls of the hole is solid, leaving a (6-8 inch) 15 – 20 cm gap to allow positioning the tanks, and backfilling with sand or metal dust, stabilized with cement dust.

  2. If there is major water seepage into the hole from the surrounding soil, the site will not be suitable. Make sure tank site is drained well. Consult your engineer for drainage design.
  3. A base of 3-4 inches (7-10 cm) of sand or crusher dust must be put in the hole and compacted.
  4. Tank must be lowered into the hole squarely by crane.
  5. Tank must then be filled with water above ground height, then back filled with bedding sand or metal dust. Cement stabilize this fill medium.
  6. It is important that tanks be buried into ground up to ONLY one half of its wall height. (It is also recommended a Molasses grade tank for its extra wall thickness).
  7. It is recommended that your outlet pick up, from the tank, comes through the tank roof, or alternative plumbing from base outlet is needed.
  8. If there are 2 x 90mm inlets coming into the tank you will require at least 2 x 90mm overflow pipes.
  9. Overflow must be piped away from the tank.
  10. Please be aware Duraplas does not endorse its above ground tanks being buried, any damage incurring to the tank due to its burial will not be warranted, the above information is to be used as a guideline only. Please seek engineer’s advice.

Using a Tank Stand:

  1. It is recommended that you contact an engineer to ensure that a suitable stand is provided to meet any relevant requirements. Remember every litre of water is 1kg in weight.water-tank-stand-installation-diagram

Be Sure to NOT Make these Errors:

  1. Rocky and uneven ground with little or no base preparation.
    water-tank-installation-rocky-or-uneven-ground
  2. Must not have undersized base. The total circumference of the tank must be supported. Ideally, allow the pad to be 100mm wider than the tank.

  3. Wooden sleepers are generally too uneven and untrue to use for base.

  4. Don’t use corrugated iron decking as a base.

Important Points When Plumbing Tanks:

Tank Overflow:

  1. Always ensure that overflow water is plumbed away from the tank. This will reduce site erosion and ensure a sturdy support for the base of your tank. Regularly check the overflow screen and clean when necessary.

    Mary Klazema
    Hi Russell, As discussed on the phone, I just wanted to commend the delivery team who delivered and installed our tanks. Jim and the boys were very professional and are a credit to the Tankworks team (who deliver the steel range of tanks for The Tank Factory). Our property has a steep driveway and Jim manoeuvred the truck so skilfully, his driving skills are outstanding which allowed the tanks to be unloaded with minimal fuss. They worked cooperatively and professionally.  Thank you to all, We are very happy to see our tanks on site and delivered safely, From, Mary Klazema

    Rowley & Clare from Dorrigo, NSW
    On 1-Oct, two 5,000 gallon tanks were delivered to our rural property outside Dorrigo. I merely write to compliment you on your delivery team of Bert & Mick who are a credit to your company. Firstly, they kept us informed of their expected arrival time. Secondly, we found them to be top “can do” blokes who skilfully off-loaded both tanks precisely where we wanted them. It is always a pleasure to interface with men of this calibre. Thank you Rowley & Clare, Dorrigo, NSW

    M Jones
    Hi Wayne, Thanks for your prompt reply. I have just paid via internet transfer. You guys are great. In the last 6 months I have bought three 22700lt tank packages from you. My plumber could not find a product even close to the quality and price you are offering. I have recommended you to two friends and both have purchased from you. Every time you, have supplied, great service, great communication and great products. Keep up the good work. When someone asks me "where is the best place to buy a water tank", I shout, The Water Tank Factory! REGARDS M JONES
  • "Considering the quality of your product, I believe I received the best available product for a good price"

    Alex from Stokers Siding
    I recently purchased a tank online (Inv 6692) that was delivered by Tweed Tanks last week. This is the 4th Duraplas tank I have purchased. I wish to commend the delivery driver on his prompt & professional service. The experience was positive & exceeded any expectation I had. I would also like to commend you on delivering a quality product. The price was not the cheapest but was extrememly competative & I chose to support a local company. Considering the quality of your product, I believe I received the best available product for a good price. I will continue to recommend & use your products. Regards, Alex from Stokers Siding
