Hi, I was looking for a sustainable way to tag surge tanks. https://en.wikipedia.org/wiki/Surge_tank
Such equipment is very useful to avoid mechanical damages to water supply infrastructure in hydraulic power plants. It absorb water exceeding in penstocks when operator decide to close valves. It can have many shapes : A surge tanks may be completely overground or be 100 m deep underground instead. Have a look to wikipedia page linked above for overground example. Here is a underground one : https://fbcdn-sphotos-f-a.akamaihd.net/hphotos-ak-snc6/p206x206/225623_2281491238376_6752456_n.jpg Location : http://goo.gl/maps/DwxDI If nothing had been defined yet, I may use water=surge_tank on a member node of a pipeline=water way. Is there any other way to map it? Thanks in advance, cheers. *François Lacombe* francois dot lacombe At telecom-bretagne dot eu http://www.infos-reseaux.com
