Yes, you could extract energy, but then your water in the house would have little umph to it. It also only produces energy when you are using water.
Energy has units of Force x distance.
Pressure is force/distance squared.
Pressure times volume = F/D^2 x D^3 = F x D
60 psi = 400,000 newtons/meter^2
So a cubic meter of water has the potential energy of 400,000 joules.
A kwhr = 3,600,000 joules. So 1/9 of a kilowatt hour.
A cubic meter is 1000 liters.
1000 liters per hour = 4.4 gallons per minute.
So by running at tap full out, you could generate enough power to keep a 100 watt bulb burning -- ignoring losses.
What does your city charge for water and sewer?
