#CMT# #/CMT# The truck (1) has a tank (2) provided with a partition (3) for separating the tank into two compartments (4, 5) respectively for clean water and sewage water. An on-board weighing system (14) constantly provides a signal representing mass of the truck. A flow-meter (16) measures volume of the clean water exit from the compartment (4) and provides a signal representing the measure volume. A drain device (17) completely drains waste water from the compartment (5). A controller (C) is connected to the weighing system and the flow-meter for determining mass of sewage residue. #CMT#USE : #/CMT# Sewer cleaning truck. #CMT#ADVANTAGE : #/CMT# The controller is connected to the on-board weighing system and the flow-meter for determining mass of the sewage residue, thus permitting to know the mass of the sewage residue extracted from sewerage system without modifying flow of sewerage operations and without wasting time. The design of the sewer cleaning truck permits to determine a fouling level of the sewage system to establish a detailed cartography of the sewage system, thus permitting the detailed cartography to offer televised inspections, to program for repair works, and to offer an improved functioning of the sewage system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a vertical longitudinal sectional view of a sewer cleaning truck during aspiration of sewage water and filling a compartment.
