Hints About Operation
Unjustified prejudices against “new” technologies still prevail. Highly assumed maintenance/operational costs are the main obstacle against further expansion of vacuum sewerage systems on the market. Problems, especially at collection chambers, and frequent system break-downs (drowning) were the birth labour of first vacuum sewerage systems. Nowadays, vacuum systems are reliable when their design is based on special knowledge of professional companies.
A monitoring system is an option to indicate the status of the vacuum valves and collection chambers.
Vacuum stations should be visited at least once a week to carry out a visual inspection. Experiences have shown that a well-designed vacuum station will not need more than one visible control and short check once a week (similar to a pumping system). Operating hours and power consumption of the pumps should be checked regularly. Mechanical and electrical maintenance, cleaning of the vacuum tank, briefly a total check of the vacuum station, should at least be done once a year (oil-change and filter change of the vacuum pumps).

Famous quotes containing the words hints and/or operation:
“The man of genius, like a dog with a bone, or the slave who has swallowed a diamond, or a patient with the gravel, sits afar and retired, off the road, hangs out no sign of refreshment for man and beast, but says, by all possible hints and signs, I wish to be alone,—good-by,—fare-well. But the Landlord can afford to live without privacy.”
—Henry David Thoreau (1817–1862)
“An absolute can only be given in an intuition, while all the rest has to do with analysis. We call intuition here the sympathy by which one is transported into the interior of an object in order to coincide with what there is unique and consequently inexpressible in it. Analysis, on the contrary, is the operation which reduces the object to elements already known.”
—Henri Bergson (1859–1941)
