Some options and accessories may be very useful for rainwater tanks. To facilitate discussions, we can place a tile at the bottom, but only at the bottom of the tank. We benefit to accommodate a low point and, if technically possible, sump. The vacuum pump-cellar will be place for the evacuation of dirty water from the interview.

The roof water will pass through a filter sediment or by a pool of sedimentation of a hundred liters, to join the slop tank. This represents approximately 20% the volume of the tank. The use of rainwater induces specific piping in the house.

Installing a drip tray of rainwater is an interesting alternative to the wells. The quality of rainwater after a tank is generally safer than from the groundwater table in your home. Rainwater is ideal for watering and more. In addition the installation of a pressure vessel is a civic operation in so far as it will serve to retain water during heavy storms and participate in the limitation of flooding.

Rainwater tanks installation is also a point to keep in hand. If rainwater tanks have become mandatory for new buildings in Australia, the technique is still confidential. It is said that this represents a shortfall for distribution agencies of water, which are powerful companies that have become for some multinationals. Furthermore, the same occurs to the companies processing water which are often the same.

The water distributed in Australia rose strongly and continues to do so. Thirty eight percent usage rose up between 1995 and 2005 and the same increase is projected for the period 2005-2015. Moreover, the inescapable climate change will cause summers to become drier. Having an alternative source of supply will therefore be a financial advantageous and increasingly important. Not to mention, a single tank of sufficient size will allow you to store water before the summer drought.

The tank has many purposes. For instance, you would want to use this system for watering a large garden (especially in the south of Australia); aim to become quasi-autonomous; use rainwater for toilets; get water even in times of prolonged drought. Make sure to hold at least 10-15 m3 which is required. For such a tank, the homeowner will refer you to a dealer or you can build it by yourself.

Switching to rainwater tanks gives you a simpler installation; a moderate cost of installation and a return on investment. Using a prefabricated concrete tank 4 m3 is an interesting compromise.
