22500L Water Tanks BAL ratings or BASIX Requirements

With new regulations implemented after past bushfire seasons, the BAL Rating system [Bushfire Attack Level] gives guidelines for properties on Bushfire prone land. Part of these recommendations are to have a dedicated fire tank [water stored for the sole purpose of firefighting].

The tanks can be made to have the Storz fitting [NSW] or Camlock fitting [Qld] installed to meet the local council requirements for the BAL Rating, on your property.

Material Options

304 Grade Stainless Steel, 316 Marine Grade Stainless Steel, Colorbond / AQUAPLATE®

Additional Fittings

Best practice for larger tanks is to also include a High suction (HS) fitting. This is a 50mm outlet and ball valve installed on the corrugation above. This allows for efficient water balancing when other tanks are connected. The HS Fitting also protects the pumps and internal water appliances as it draws only clean water from above the sludge / anaerobic level.

You may also wish to purchase a Bucket Height Tap for example, where the tap is placed high enough from the base, to allow gravity feed of water, into a bucket placed under the tap.

Customer Reviews

We purchased 2 x 22,600 litre stainless steel tanks and from start to finish the process was exceptional. Linda with the ordering process and booking was great to work with, keeping us informed and arranging the intestate delivery right on schedule. Lloyd the delivery driver was a legend and sorted these massive tanks into position, making it look easy. Tanks are well made and finished, really good experience. It was a pleasure being part of your project and supplying the stainless steel rainwater tanks. Was great working with you through the process. We agree, Lloyd is very experienced with handling the tanks and various site conditions and a great guy to have on the delivery team. Thank you for supporting our business. All the best.

Thank you Linda for all your help from the office. You made the whole process very smooth.
Jason and Loyd arrived early in the morning on time with our two 22,000 litre stainless steel water tanks ready to nut out a difficult tight hillside tank pad. They navigated the site with obvious experience and skill in reverse!!!!!….very impressive teamwork boys.
I would highly recommend Select Water Tanks to anyone looking for beautifully made solid tanks at competative pricing by a professional team ready to go that extra mile for their clients. Thank you so much Tina. All that rain made things a challenge, but we got the tanks there. Was a pleasure being able to help you with your order from initial contact through to the delivery. All the best from the Team at Select Water Tanks.
