As I wanted to catch rainwater and caught dry
Napojení na okapový svod jsme zvládli snadno.

A těšil jsem se na to, jak díky ní budeme zalévat nově vysazené stromy na společném pozemku. Zalévat stromy pitnou vodou z vodovodu mi totiž přišlo lehce dekadentní.Víme, reklamy jsou otravné.

But it didn't turn out as I imagined.
Our quite small apartment building (12 units) has an architect of thirteen vertical gutters.We drilled one of them with neighbors, deployed the bought part for water trap and attached to the barrel.The total investment of about ten thousand crowns is lost in the budget of the house, the water will serve to water the trees or to play children.There's nothing to go wrong with.
The water trap device is inventing so that the water supply to the container turns off for the winter, the water is released from the container and any frost does not tear it.And in the spring the water supply simply turns on and then just waits for the rain.
This year I ended the winter with the first heavy rain already in February.It didn't seem that the frosts would come back, it was more than ten degrees and it was really nice to.So I released the rainwater into the container.Was full of basically immediately.And most of the February raining thickened the gutter into the rain sewer.

But in March or in April it was almost no raining at all.Exactly, it did not rain so that something stalks from the roof into the eaves.Everything was pretty good on the roof.
The barrel is empty.The trees are young, planted in the autumn and the gardener who was planted, recommended to water.So I water but the drinking water.Which is slightly decadent.
What is for the lesson?
That if you decide to catch rainwater, it makes sense to think more in a large.It is necessary to use in the last drop of the period when it rains and to hide water for the time when the sky is swept.Those 350 liters are woefully little.
Now I know we were supposed to buy a bigger barrel.To our house we were looking for something that looks a little.After all, we are in the city and IBC container is not quite suitable for our house.For nearly 20,000 crowns you can buy above -ground containers that have a volume of 2,000 liters and do not look quite terrible.Maybe we were supposed to get here.
And I think that if we invested as a house in a large, multiple underground reservoir, so on the rain will fill it February and we had water enough for the whole summer.
350 litrů, to je jako nic.Licence |Některá práva vyhrazenaFoto | Martin Mach Ondřej / Ekolist.czIt just doesn't give economic sense.Not at a time when you buy a cubic of drinking water for a hundred crowns.The Dešťovka subsidy program counts on the fact that without a subsidy investment in an underground tank for watering the garden will return within twenty years, with a subsidy within ten.Personally, I think that without a subsidy, the return may not be twenty years old because you can do something cheaper, yourself, without an invoice.
The investment of ten thousand for a 350 -liter tank is lost in the budget of the house and there is no need to solve it in any way.Just to gross and over the thumb I estimated that the investment for the acquisition of an underground tank would cost our house to 80 - 100 000 crowns.Let's say twenty -five thousand for the reservoir, something to the dwarf for earthworks, something to the master who takes the excavated soil, something to the master who connects it all and acquires different pipes, to the pump (and the need to bring electricity) or a hand pump.Something behind the backfill with gravel.That will roughly be.

Bytový dům, kde se splachuje přečištěnou vodou z koupelen? Ano, mámeWe could draw a subsidy from the Dešťovka program and lift half of the eligible costs.But our committee is currently trying to check in paperwork to subsidize for discontinued trees.We would probably manage the next subsidy, but first we would have to agree at the assembly that we will invest in an underground water tank.
Investing in an underground tank makes sense only when you flip it in your head.When you think that a cubic water costs less than 100 CZK, but you say it is nonsense to send water from the roof to the sewer and water trees to water drinking water.
In a family house you make such a flip easily.In an apartment building it is much worse because you have to flip more people's thinking.Did you see the film owners?So.
It will make sense if you want to prepare for the fact that the drought will not just leave and the rainfall will mostly be when you do not need to water while you need to water it will not rain.It may also happen that drinking water from the water supply will increase or in places may not even be.
Then it will give a damn sense.
