Power Generation from Stored Energy

My wife is also saving me to bankruptcy.

How do you intend turning the coal station on and off?

In any city, the main pipeline is of large diameter and then the distribution lines drop in diameter like the roots of tree (the main root, sub root, fibrous roots etc).

This and some times orifices are used to ensure that the man in the end of the line also get the water.

If you start the pipe with 2" dia and the distributions also with the same dia, who stops tha man in the beginning from doing the garden flooding with tha water and keeping others dry (especially if he high at a height?)

In fact this is what we got at our coloney too (till they put orifices in the line).

The water supply authorities supply you a certain quantity of water and expects the water pressure to build up due to less withdrawals. But unortunately due to drains it doesn't. In our coloney after orifice, we are getting enough water in our overhead tank (provided we control the water in the gardening) without any sump+pump.

Control the usage, and you will get the pressure. But since that is not in your control, the whole society has to do it, do what we have done, ask your supply authority to put the orifices at distribution points or some other control devices.

In the UK, the water regulations require that mains potable water is delivered to the home at a minimum pressure. All water for consumption, cooking, etc., is distributed from what is known as the rising main, which feeds a storage tank in the loft (usually) via a Portsmouth Valve. All non-potable water is delivered from there by gravity. The Portsmouth Valve is there to provide a type 1 air gap so that any biological contamination from the tank (a decaying dead bird inside it, for example) cannot enter the rising main via the valve connection should the supply fail.

In considering alterations to district water schemes, the regulations applicable in that locality must take precedence over any economic considerations. The regulations are there to maintain public health. It is no good saving a few coins-worth of expenditure on pumping water around if the outcome is a major health epidemic that causes a significant dent in the local or national economy!
