When mentioning infrastructure most people will think
of roads and rails. They are forgetting that there is a hidden world of
infrastructure that lies beneath our streets. This hidden infrastructure is equally
important for the well-functioning city and consists of sewage pipes,
electrical cables, water pipes and communication cables such as fibre optic cables. The rules are that this subterranean infrastructure is built in the
location indicated on the permit. Alas it often happens that contractors place
them where they can get them in easiest resulting in broken cables and
destroyed pipes when years later another contractor starts digging...
Sewage pipes used to collect both clean rain water and
the dirty waste water from homes and businesses. Now this system is changed in
separate pipes for each to better manage flooding and spend less on water
treatment. This means two smaller pipes instead of one larger pipe. Drinking
water (in the middle) comes in via separate pipes with these typical home
connections in the standard household width.
