Greetings, I know these systems are very expensive, but great at reducing infiltration issues. I think City of Boca Raton in Florida has a vacuum system. Probably more expensive to retrofit an old system but easier if it is a brand new development for obvious reasons...

Hi Christina,
thanks for your opinion. I was a bit surprise. During my research I found that for installation in most cases vacuum sewers had comparative cost advantage against gravity sewers and not to forget the environmental benefits. I think the cost advantages derive from lower trenching and material cost in comparison with gravity sewers.
But I do wonder about the operational and maintenance costs since many communities seem to have issues with the valves.
Which raises the question why hasn't this system been implemented more often if it has so many benefits?
