摘要： PROBLEM TO BE SOLVED: To more reliably remove foreign matters from a water flow channel. SOLUTION: A flowmeter 20 and an in-line filter apparatus 10 are installed in the downstream side terminal of a block water pipeline. The in-line filter apparatus 10 is equipped with a filter 5 having a function of trapping foreign matters, a freely openable or closable drainage pipe 9 and a filter back washing drainage pipe 8 installed in the upstream side and the downstream side, respectively, while sandwiching the filter 5. At the time of washing a pipe, both drainage pipes 8 and 9 are alternately opened based on the numeral value shown by the flowmeter 20 to increase the flow speed in the water flow channel to promote removal of the foreign matters by the increase of the flow speed. Further, a flow channel from which the foreign matters are to be removed is specified by operation of a switch valve installed in the middle of the block water pipeline and another flow channel is closed to further increase the flow speed. Furthermore, since the filter 5 of the in-line filter apparatus 10 is positioned in the downstream side of the pipe washing position, the foreign matters can be trapped and prevented from flowing to the flowing water pipe P in the downstream side.

摘要： PROBLEM TO BE SOLVED: To easily specify the positions where a turbid substance is likely to deposit in a whole area where tap water is supplied, and to easily determine the timing of washing of piping. SOLUTION: The whole area is divided into a plurality of meshes 2. Speed of increase of the turbid substance in each mesh is estimated by performing multi-regression calculation employing the speed of increase of the deposit amount of the turbid substance 18 as objective variables, and employing the number of dead ends 6 per unit length of the piping 3, a ratio of the piping length of a mortar lining piping laid before the year 1990 to the total extending length of the piping, and three of coefficient of discharge as explanatory variables. A result of an analysis for each mesh is two-dimensionally displayed on a display screen 1, so that the deposit condition of the turbid substance for the whole area can be grasped visually. Further, as the timing of washing the piping is calculated by dividing an acceptable deposit amount of the turbid substance by the speed of increase and is displayed two-dimensionally, distribution of the timing of washing the piping in the area can be easily determined.
