In regions where drinking water is not available, water tanks are a valuable resource. Homes in urban or peri-urban regions may also benefit from the installation of water tanks.
Your tanks will most likely be filled with rainwater from your roof, but they may also be linked to a bore or supplied with water from a water carting service. Unless it has been polluted or kept poorly, rainwater in most regions is typically safe to drink. Contaminants in rainwater include:
- Droppings from birds and other tiny animals (for example, lizards, mice, frogs and possums)
- Other detritus containing tiny creatures, such as dead animals and insects
- Any neighbouring industrial pollutants or excessive road traffic might pollute the air and rainwater.
- Dust from industrial or agricultural activity, as well as pesticide spray drift
- Wood heaters, smoke or other emissions
- Storage in an unkempt water tank or unclean pipework
The Ultimate lists of Do’s and Don’ts for Outdoor Water System:
The key to optimum water quality for your house is regular maintenance of the whole system, from the roof to the overhead water tanks to the tap is as follows:
- Keep the gutters and downpipes, as well as the roof catchments, clean and clear of leaves.
- Remove overhanging tree and shrub branches, as well as suitable perches for birds like cables and TV antennae.
- Cover the inlet and overflow of your tank with a fine steel mesh to prevent birds, animals, and insects from gaining direct access to the water.
- Ensure your tank is covered to keep light out of the water since light stimulates bacteria and algae growth. In addition, a firmly sealed opening in the lid should enable access to the tank for cleaning and inspection.
- Using a first flush diversion system, let the first decent rains rinse the roof and gutters and run off the waste each year. Using a first flush diversion device will keep the initial section of roof runoff out of the tank, which is more prone to accumulate contaminants.
- To avoid metal corrosion and contamination, make sure guttering and piping are self-draining or have drainage ports.
- Keeping the leaf trap clean is the key to limiting the number of leaves and debris entering the rainwater tank through the entrance.
- Collect rainwater from a roof that is not:
- composed of wood that has been treated with a preservative (copper chrome, creosote or pentachlorophenol)
- Bituminous materials are used to cover the surface.
- Lead-based paints were used to cover the walls (including any gutters).
- Contamination of water tanks from roof-type water collection systems is a common occurrence if not monitored properly.
- Collect rainwater from parts of the roof without the usage of:
- a wood-burning stove’s chimney.
- Roof-mounted items such as evaporative air conditioners and hot water systems have discharge pipes.
- wood that has been chemically treated.
Water System Planning Requirements and Uses:
The amount of water you’ll need to meet your demands is determined by:
- The available area on the roof
- Size of a rainwater tank
- How much water is utilised in and around your home
Rainwater from your roof can help you meet your yearly water demands while also conserving drinking water reserves if you use it for things like:
- irrigating your garden
- using the toilet
- doing your laundry
- cleaning your automobile
Bore water is useful for stocking water, irrigation, flushing toilets, washing clothing or automobiles, depending on local water availability. However, bore water should not be used for drinking, bathing, watering edible plants, food preparation, or cooking unless thoroughly tested and treated.
Inspect your tanks every 2 to 3 years for sediment (sludge) collection on the tank floor. Opening the sludge or scour valve at the bottom of the tank is the simplest technique to remove sludge. Keep in mind that a tank’s interior is a restricted place with limited ventilation. Consider hiring a professional tank cleaning service if you need to clean your plastic water tank.
