In Berlin, from 1961 until the wall came down in 1989, more than 5,000 East Germans managed to cross the border, a number of them through the sewers system.
While the water supply was disconnected between both part of the city since 1950, the sewers remained city wide for a long time but secured by grills, electric systems, etc.
During this time an extensive program of division of the sewer system between both parts of the city was started with new sewage pumping stations and pressure sewer lines.
Several escape attempts through the sewers were repeatedly until 1980.

Recently renovated, the 18th Century,Jal Mahal (“Water Palace”) is located in the middle of the Man Sagar Lake in Jaipur city, Rajasthan, India.
It long remained an abandoned dilapidated palace in the midst of the sewage laden lake. With the urbanisation of Jaipur city and areas surrounding the lake, the ecological system of the lake and its vicinity deteriorated drastically.
A major clean up of the lake lasted 6 years and included re-alignment of city drains, de-silting and planting schemes.
Chilean architect Mathias Klotz designed one of the new water towers constructed to replace those damaged and destroyed during the 2010 earthquake. He was asked to come up with a concept to make the towers more attractive without changing the original shapes, which have become recognisable landmarks.
Along the same lines as wind activated works (Like Ned Kahn’s Liquid pixels), they came up with a system of metal panels that move with the wind. “The idea was to produce a skin whose surface was altered by the wind so as to resemble the appearance of the surface of the water when the wind is changed”.
This year the Medicis aquaduct in Paris is 400 years old. Built to bring fresh water to the city to replace the poluted river water, it supplied first the king’s palace, then the the religious orders and finally 14 public fountains.
As well as a series of visits, an exhibition of pictures of some infrastructures above and under is touring.

Mexcaltitán is a small island city off the Pacific coast of Mexico. The town sits low in the marshy, mangrove-lined channels that surround it, and during the June to October rainy season, water floods the streets and everyone rows from place to place in boats.

Living model illustrating principle of the Forth Bridge.
The central “weight” is Kaichi Watanabe, one of the first Japanese engineers who came to study in the UK, who worked as a construction foreman on the bridge.
The Forth Bridge was completed in 1890 and is still used as a main railway connection.

"During the 1950s and 1960s, the Hydro-Electric public utilities in the metropolitan region of Toronto built structures known as ‘Bungalow-Style Substations’. These stations were constructed in a manner that mimics the style and character of the different neighborhoods [at the time], complete with windows, blinds, and bourgeois landscaping".
The temporary footbridge used by the Brooklyn Bridge workers became a dangerous but popular attraction for New Yorkers.
The sign at the entrance read “Safe for only 25 men at one time. Do not walk close together nor run, jump, or trot. Break step!”
