One of the great myths about vacuum sewers is that they have more operational problems than traditional gravity networks. This is simply not the case. Certainly if something bad occurs in a vacuum system, like a blockage, the operator is notified quickly via alarms; he finds the problem quickly and solves it without the homeowners being adversely affected or overflows occurring.
Gravity sewers though are prone to things going wrong for years and years without operators becoming fully aware until sewerage is flowing down the streets or onto the beach.
Although the decision makers like to think that gravity sewers are easy to maintain and donâ€™t have problems, we thought it worthwhile to explore some of the main problems that operators of sewerage networks come across during the course of their day versus what the operators of a Flovac vacuum system may find.
