Page "Hydropower" Paragraph 11

Hydraulic power networks also developed, using pipes to carrying pressurized water and transmit mechanical power from the source to end users elsewhere locally ; the power source was normally a head of water, which could also be assisted by a pump.

These were extensive in Victorian cities in the United Kingdom.

A hydraulic power network was also developed in Geneva, Switzerland.

The world famous Jet d ' Eau was originally designed as the over-pressure relief valve for the network.
