We already know that we can make use of the water that we collect in rain water tanks for a variety of purposes such as washing, flushing the toilets and for our garden. However many of us have this question whether the rain water collected in the water tanks can …
Not many people know that they need to establish nature of usage of the water they store in rain water tanks prior to ordering and installation of the rain water tanks. The choice of your water tanks and the nature of preparation will change depending on the nature of usage. …

NSW Rainwater Tank Rebate is available for the installation of any new rainwater storage system in a residential property’s. The tank or combination of tanks must be: 1) a minimum capacity of 2000 litres 2) purchased in full and installed between 1 July 2007 and 30 June 2011. Households not connected to the town water supply are eligible for a rebate for the purchase of the tank only. Rainwater tanks installed to comply with BASIX (the Building Sustainability Index)external link for new homes, major renovations or a pool installation are not eligible for a rebate If you combine Rain water hogs together it is the combined size that counts.

For every 1mm of rain that falls on a square meter surface, such as a roof, one litre of water can be collected assuming none is lost . The Formula to calculate Rainwater harvesting yield is : (Amount of rainfall in mm) x ( Area of the roof in square metres) = litres of rainfall So for Example: Area of roof = Length x Width = 20 m x 15 m = 300 m 2 (square metres) Amount of rain = 1 mm Litres of rainfall = area of roof x amount of rainfall = 300 m2 x 1mm = 300 litres Rainwater harvesting yield is a post from: Rain Water Tanks

The Grundfos CH and CHN pumps are a non-self-priming, horizontal, multistage, centrifugal pumps. The Pump and motor are integrated in a compact design making the pumps suitable for installation in compact systems. The pump is fitted with a maintenance-free, mechanical shaft seal and through-going pump-motor shaft. The Grundfos Pump Genie is an interconnect device that allows you to save drinking water by using your harvested rainwater for , laundry, toilet and garden applications. The Grunfos Pump genie is always prioritizing the use of rainwater, and will automatically switch over to a mains water source when your rainwater tank is running low, or during electrical failure. The pump is only active when the rainwater is being drawn from the tank. It does not operate when the Pump Genie has switched to mains water. The pump controller automatically starts and stops the pump when a demand is sensed – for example, flushing a toilet or filling a washing machine. The CH and CHN pumps are designed for small domestic and industrial systems. Applications include • Liquid transfer and circulation of liquids within light industry and farming • Pressure boosting in single-pump and multi-pump booster systems • Domestic water supply • Cooling systems • Air-conditioning systems.

The following article is from the department of Heritage water and the arts. “When selecting a rainwater tank it is important to consider the average annual rainfall in your area, the water collection area( roof) and what size tank is most relevant to your household needs. ( See our article on comparing tank types ) In addition, you should consider the plumbing , planning and public health requirements of your local area. Rainwater Yield and Capacity The yield of your rainwater tank is the amount of water you will be able to harvest from your tank. The yield of your tank will be influenced by the volume and timing of rainfall in your area, the volume of your tank and choices you make in using your rainwater. Key factors influencing rainwater tank yield will vary according to the specific circumstances of your property, and may include: Collection area (roof size): To calculate your runoff, 1 millimetre of rain on 1m² will deliver 1 litre of water into your tank. As a rough guide: An average single carport is approximately 25m² The roof of an average 3 bedroom house is approximately 150m² The roof of an average 4 bedroom house is approximately 200m² The roof of an average 5 bedroom house is approximately 300m². Rainwater tank size: The size of your residence and your household needs should determine the size of the rainwater tank you choose. There are a range of products available in different shapes, sizes and materials. Generally, rainwater tanks can be classed as: Small – less than 2,000L Medium – between 2,000L and 10,000L Large – greater than 10,000L. The number of occupants in the house: It makes sense to assume that the larger your household, the faster you will use your rainwater supply. Your internal and external water use practices: By connecting your tank for internal use in the toilet and laundry you will increase your rainwater tank’s yield. Local climatic conditions: The rate and timing of rainfall varies significantly across Australia, as shown in the map below. The climate where you live will have an important impact on the yield of your rainwater tank. You should consider the characteristics of your seasonal rainfall zone when deciding to purchase a rainwater tank. heavy tropical rains of Queensland and the Northern Territory; relatively consistent year-round rainfall in Victoria, Tasmania and much of New South Wales; mediterranean climates of south west Western Australia and southern South Australia, characterised by significant rainfall during winter and relatively dry summers; and arid climates of north western and inland central Australia, characterized by low rainfall all year round. BOM rainfall map Examples The following scenarios are provided to illustrate how you might use this information to decide on your rainwater tank purchase. A couple living in Darwin in a 150m² home intend to use their rainwater tank water for flushing a water efficiency labelling and standards (WELS) rated dual-flush toilet and washing their car and a boat once a fortnight. Because they live in a highly seasonal rainfall region, they can expect to go long periods without having their rainwater tank replenished and should consider a large tank. A single retiree lives in a 100m² unit in Brisbane. She wants to install a rainwater tank so she can water her small rose garden and lawn, and for use in her WELS-rated washing machine. She waters her garden every second day. Because she lives in a region with a wet summer and low winter rainfall, and only has a small space in her garden for a tank, she should consider a medium sized tank. A family of five live in Melbourne in a 300m² home. They would like to use rainwater for their WELS 3-star rated 6/3 dual flush toilets and WELS 4-star rated washing machine. They live in a seasonal, winter
Some photos of rain water hog tanks in action : David Gottfried Chief executive officer of regenerative ventures and founder of U.S green Building council and World Green Building council recently refit his remolded Oakland home with Rain water Hogs helping to achieve Platinum certification . 9 slimline water tanks can be found helping to reduce the water use by over 50% . Six collectors gather rainwater from the homes roof and are connected to provide enough water to run one of the dual flush toilets for up to 9-12 months. Other water tanks are used for watering the potted plants and two are collecting greywater from the tub sinks and showers to to mainly water native plants in the garden Here a SimpleViewer Flash gallery should be displayed.

A study initiated by the National Water Commission analysed the cost-effectiveness of installing a rain water tank from the perspective of the home owner in different regions of Australia. The study investigates how cost effective rain water tanks are as a substitute for mains water supply. The report highlights that the yield and the cost of rain water tanks varies significantly based on individual household variables, including the size of the roof collection area, water tank size, number of occupants in the home and annual rainfalls. A water tank’s yield is determined by both the volume and timing of run-off into the tank and the volume and timing of usage. The water tank report is available as a PDF download from the Victorian Water Industry association website.
