Rainwater tanks, known to be an investment

A good compromise efficiency and investment is a Concrete water tank. It is the choice of a medium capacity tank, used mainly for washing machine and toilets. At these countenances, the tank will be the least expensive obtained by purchasing a concrete septic tank. In Europe.. a 4 m3 to 3 m3 default tank can cost starting at 750 instead of 1500 to 2000 euros for tanks of similar size at a specialist dealer.

When looking at a typical consumption for a family of four persons the WC saving is about 30 m3/year. The standard toilet usage comes to about 60 m3/year. The washing machine which can be considered luxurious is still an appliance that uses a lot of water and that washing machine Class A used about 11 m 3 / y however the Class C uses 18 m 3 / y.

You may wonder when and were you would have the installation of such a tank. The shelter from heat and light avoids exposing the rainwater to a risk of bacterial contamination. It is therefore imperative to bury the tank rainwater. If you build your house, the ideal choice is to install your tank when connecting your home to networks and plumbing. In other cases, you diminish the installation costs by taking advantage of the arrival of a digger for other works such as building a garage or a swimming pool.

Did you know that one can use a septic tank as a water butt, nothing can be simpler. The instructions follow: simply connect the drain pipe to a tee on which should be connected a standpipe forming with overflow. To permit emptying of the tank, the other end of the tee will be closed by a screw. The pipes are usually PVC 100mm diameter.

In the general case, the slope does not compensate for the height of the tank. The standpipe may well go on condition as long as its level does not exceed the top of the overflow. By cons, for higher volumes, we must put more tanks in series that requires getting a large enough field and at least a slight slope. The main pump is placed in one of these tanks in case of “fuel starvation”, you will transfer water from another tank with a pump garden, for example: the advantage of a concrete tank

Naturally slightly acidic, the pH of rainwater will be easily be rebalanced if storage is realized in a concrete tank, because the cement alkali neutralizes the acidity.
