Vattenledningen som sprungit läck kan vara "upp till 70 år gamla". Det är väl ingen ålder för vattenledningar, med stockholmsmått mätt?
Har för mig att många vattenledningar här är över 100 år, men jag kan ha fel.

A burst water main caused a major flood at the Metro station of Helsinki’s Central Railway Station on Sunday and could force the closure of the city’s busiest station of the underground Metro system for months.
Helsinki City Transport estimates that repairing the water damage could cost millions of euros.
From Sunday afternoon, all five Metro stations west of Sörnäinen were closed because of the flooding. Today, Monday, Metro service will be available all the way to Kaisaniemi station, which means that only three stations will remain out of commission.
Transport authorities hope that by Tuesday, the Metro trains would be able to go past the Central Railway Station without stopping, making it possible to restore service to the Kamppi and Ruoholahti stations. Before that, a special bus line, 65X, will operate from Kaisaniemi to Ruoholahti.
