<p>Disclosed is a sewer cleaning truck comprising a tank (2) that has a partition (3) for dividing the tank into a first compartment (4) for clean water and a second compartment (5) for sewage water. The tank also has a discharge opening (12) located downstream of a retaining means (13) that lets wastewater penetrate therethrough while retaining solid waste. Said truck further comprises means for filling the first compartment (5) with clean water (9), means (10) for pressurizing the clean water which is injected into a sewage system that is to be cleaned, and means (11) for sucking up the sewage water and waste and conducting the same into the second compartment (5). The truck also comprises: a vehicle load weighing system (14) for continuously supplying a signal representing the vehicle weight; a means (16) for measuring the volume of clean water discharged from the first compartment (4) and supplying a signal representing the measured volume; a control device (17) for ensuring that all the wastewater is discharged from the second compartment (5) following the sedimentation process; and a calculator which is connected to the weighing system and the means for measuring the volume of supplied and discharged clean water in order to determine the weight of the extracted sewage waste.</p> |
