How to Understand What Type of Rainwater Tank Rain Water Tank Is Best Suited For Victorialeelbourne, Victoria

There aren’t many consolations to a rainy day– cosy sofa time, soothing sounds of drops on the roof, and perhaps a rainbow or a puddle-splash afterwards. But you can add another by installing a water tank to capture a bit of that downpour: it will reduce your environmental footprint by decreasing your demand on mains water and the amount of stormwater runoff into rivers and oceans, and can also reduce your water bill in the long term.

Rainwater tanks are no longer just huge, round and ugly; they come in all sizes and shapes that can make efficient use of modest or tricky urban spaces.

Water for outdoor or indoor application?

Probably the most important issue to consider before you buy and install a rainwater tank is how you intend to use the water.

Employing the caravan water tanks outdoors– for watering the garden and washing the car, as an example– is the best way to start, as you probably just need the supplier to set up the rainwater tank, as opposed to a licensed plumber. And it will immediately cut your consumption of mains water.

Save a lot more by sending the rainwaer to your toilet, washing machine or hot water system, but you’ll need a licensed plumber to connect the rainwater tank to your mains supply.

What size water tank do I require?

The storage capacity you choose will be dependent on the size and shape of your household and garden. Round, squat tanks fit well under a deck, while slimline tanks are good for narrow spaces. An underfloor tank or bladder storage system is a good out-of-sight space saver, although is more expensive.

Your roof area and the annual rainfall in your location will also need to be considered. To help determine the size and shape that’s best for you, sellers often provide calculators on their web pages, or your water authority may be able to help.

What else do I need to understand before buying a water tank?

Materials

Rain water tanks generally come in the following materials:

Metal tanks are made from corrugated or flat rolled metal, which might be galvanised or coated. They often include a plastic inner lining (Aquaplate) that will increase the life of the tank and shield the water quality.

Polyethylene (plastic) tanks are popular as they are comparatively cheap and durable. Because rust isn’t a conern, they are a very good option for people living near the ocean. Other synthetic materials, such as PVC and geotextile, are used for bladder storage. Bladders work for water storage below a deck or floor; while their material is strong, it’s not intended for outdoor installation.

Fibreglass tanks are rust and chemical-resistant and manufactured to withstand extreme temperature levels. They’re not the cheapest option, and preferable for above-ground installation, while all other types can also be installed below ground.

Concrete tanks, more often used for agricultural and industrial purposes, won’t rust, burn, melt or blow away. They may be bought ready-made, or customized onsite.

Regulations

Ask your community council and water supplier which rules and regulations are applicable in your region. You may need to provide a development or building application, and there may be policies around drinking rainwater or mosquito breeding prevention, as well as restrictions on the tank’s placement, colour, height and labelling or noise regulations for a pump.

Are you remodeling, building new or retrofitting?

If you are refurbishing or building, instead of retrofitting, you may need to incorporate energy and water-efficient characteristics in your plans to comply with new legislative requirements.

Extra expenses

When obtaining quotes, inquire if there are any additional costs for delivery and installation; extra materials (such as pipes, fittings and taps); alternative extras (such as a first-flush or backflow-prevention device); a pump (unless you can work with gravity for water pressure); and a stand (unless you would like to put it on the ground or below it, in which case you’ll need to factor in the cost of special ground prep or excavation).

If you wish to connect the tank to your mains water supply, think about the cost of a licensed plumber, and charges for any extra work that needs to get done to your roof and/or guttering.

Can you receive a water tank rebate?

Contact your local water or government authority to see if you’re entitled to a cash rebate or bill reduction– the answer may rely on the size of the tank and whether it’s connected to a toilet and/or washing machine.

Cost

Rainwater tanks can range from around $700 to $2000, starting from a small, freestanding model without pump or extras, to large, custom-built models. Costs vary depending on the size, material, finish and strength of the tank.
