[Disclaimer: This technology in no way, nor intention adversely affects the public utility, any cost there to, or produce significant amounts of excess waste water. The Water, Pressure Differentials, and Potential Energy of the proposed systems is "Post Meter", and has already been paid for by the customer. This technology is not intended to cheat the water company, artificially alter your bills, or any type of scam or mal intentions.]

The proposed series of systems utilizes the potential in pressure differences throughout your home.
there is a great range of pressures and water flow rates, by which we use our daily water. From cooking foods to flushing the toilet, taking a shower, or watering your garden. The difference in pressure, and flow-rate,is compensated in the design of the apparatus. For instance, your toilet uses a low-flow, or constricted rate of flow, to fill the tank. The water pressure is dropped from ~70psi to 0 (or atmospheric pressure). Now, we could blast this toilet with 150 psi straight off the in-line, and fill the tank very quickly. but that would just be ridiculous.... so we run it through a pressure regulator, drop it down to 70psi, then through a narrow pipe into the toilet, with a couple of restrictive-flow valves we can adjust. This fills the toilet at a reasonable rate, while lowering the pressure. This is one example of many throughout the house, in which the pressure and flow rate are altered to fit the needs of the appliance or use.

In addition to the faucets, hoses and various attachments we connect to our home water lines, there is a wide range of applications for which we do not need a great pressure. these include cooking, drinking water, gardening/irrigation, pools, ponds, fountains, and many more which I do not list here.

What I propose is that we can utilize this differential in pressures and flow rate, to generate electrical energy (or motive force).
The energy in this system, ultimately comes from the local water tower, pumped by heavy machinery, then piped to your meter.
(what we do with our energy after we buy it... is up to us right?)

The primary generator in this series of systems consists of a variable-pressure tank. Positioned between the line-in and the pressure regulator.
[ Many of you have pre-regulator hose connections on the side of your house facing the meter, and you know the difference in pressure. It's about twice as much pressure, and water coming through the hose!!]

The pressure of the tank ranges from 70Psi (standard in-home use) up to 150Psi (water tower pressure).
a hydroelectric turbine utilizes the pressure difference of 75Psi to generate electricity, while storing water in the tank.
When tank pressure reaches 150Psi, the turbine shuts off, until water is used.

The pressure regulator keeps like pressure at 70Psi, and the system does not disturb your home water supply while generating energy from the water tower potential.


Any number of secondary hydroelectric generators can be implemented throughout the house to generate electricity.
Using the pressure differential between 70psi and the appropriate pressure of the intended application.

The toilet and Water Heater are two obvious applications. Further technologies might include a garden-hose generator, or something in your kitchen that powers your lights while you fill a pot of water.

Please share your thoughts on this subject. There are already several independent inventors that have done similar things along these lines, but what i propose is a unified goal of social impact.
We should all get on board and look for things like this in our daily lives, and see how this type of thinking can change the world.

I do not vouch for the claims made in these videos, but here are some inventive ideas that utilize this principal.

Things to note are: The particular line-in pressure available at your home, will vary with distance from the water tower.
Power Generation in this manner is dependent upon flow-rate, not only pressure.
Applications that use more water, can generate more power.

This is a basic diagram, showing the placement of the primary generator.
In-line with the incoming water flow, before the pressure regulator in your home.
This energy is already paid for in part of the cost of your water.
These systems are designed to make use of it.

Add a charge controller and a USB socket... energy on tap!! :D

given the current cost of electricity, this type of technology could offset the entire cost of our water bills

My water bill is just about always the minimum, $12.50 USD per month.

My electric bill, level billing, is just about always $84 USD per month.
