There aren’t many consolations to a rainy day– cosy lounge time, soothing sounds of drops on the roof, and possibly a rainbow or a puddle-splash afterwards. But you can add one more by building a water tank to capture some of that downpour: it’ll diminish your environmental footprint by minimizing your demand on mains water and the quantity of stormwater runoff into rivers and oceans, and can also cut your water bill in the long-term.
Rainwater tanks are no more just huge, round and bad-looking; they can be found in all sizes and shapes that can make efficient use of minimal or tricky urban spaces.
Water for outdoor or indoor use?
Easily the most important issue to consider before you buy and install a rainwater tank is how you would like to use the water.
Using the water outdoors– for watering the garden and washing the car, as an example– is the simplest way to start, as you most likely just need the supplier to set up the water tank, as opposed to a licensed plumber. And it will promptly cut your utilization of mains water.
Save a lot more by sending the water to your toilet, washing machine or water system, but you’ll need a licensed plumber to connect the tank to your mains supply.
What size water tank do I require?
The volume you choose will be dependent on the shapes and size of your household and garden. Round, squat tanks fit adequately under a deck, while slimline tanks agree with narrow spaces. An underfloor tank or bladder storage system is a good out-of-sight space saver, but 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 correct for you, sellers often provide calculators on their websites, or your water authority may have the opportunity to help.
What else do I need to recognize before investing in a rain water tank?
Water tanks typically come in the following materials:
Metal tanks are made from corrugated or flat rolled metal, which might be galvanised or coated. They often come with a plastic inner lining (Aquaplate) that will increase the life of the tank and shield the water quality.
Polyethylene (plastic) tanks are well-liked as they are fairly cheap and durable. Because rust isn’t a conern, they are a good option for people living near the ocean. Other synthetic materials, such as PVC and geotextile, are applied for bladder storage. Bladders are useful for water storage below a deck or floor; while their material is durable, it’s not intended for outdoor installation.
Fibreglass tanks are rust and chemical-resistant and created to withstand extreme temperatures. They’re not the cheapest alternative, and more suitable for above-ground installation, https://julianhefner534.weebly.com/ while all other types can also be set up below ground.
Concrete tanks, often used for agricultural and industrial intentions, won’t rust, burn, melt or blow away. They may be bought ready-made, or custom made onsite.
Ask your local council and water supplier which rules and regulations apply in your area. You may need to submit a development or building application, and there may be policies around drinking rainwater or mosquito breeding prevention, together with restrictions on the tank’s specific location, colour, height and labelling or noise regulations for a pump.
Are you refurbishing, building new or retrofitting?
If you are remodeling or building, rather than retrofitting, you may have to incorporate energy and water-efficient elements in your plans to abide by new legislative requirements.
When obtaining quotes, ask if there are any additional costs for delivery and installation; extra products (such as pipes, fittings and taps); optional extras (such as a first-flush or backflow-prevention device); a pump (unless you can use gravity for water pressure); and a stand (unless you want to put it on the ground or below it, through which case you’ll need to consider the cost of special ground prep or excavation).
If you would like to connect the tank to your mains supply of water, consider the cost of a licensed plumber, and expenses for any supplementary work that needs to get done to your roof and/or guttering.
Can you acquire a water tank rebate?
Check with your local water or government authority to see if you’re entitled to a cash grant or bill reduction– the answer may depend upon the size of the rain water tank and whether it’s connected to a toilet and/or washing machine.
Rainwater tanks can vary from around $700 to $2000, starting from a small, freestanding model without pump or extras, to large, custom-built models. Costs vary depending upon the size, material, finish and strength of the tank.
