A maintenance method of an initial rainwater disposal system is provided to heighten efficiency on operation and maintenance of an initial rainwater disposal system by maintaining an initial rainwater disposal system without mobilizing manpower for maintenance and equipment such as a suction pump vehicle, and to maximize the disposal efficiency of initial rainwater by improving convenience of maintenance. A maintenance method of an initial rainwater disposal system for cleaning up and filtering out sedimentary deposits contained in compulsory detained impurities, captured sludge and soils automatically comprises the steps of: storing up washing water for cleaning up an initial rainwater disposal system(1); detecting the inflow of initial rainwater and the filtration of sedimentary deposits contained in compulsory detained impurities, captured sludge and soils using a detector; draining off the washing water stored in a water tank according to the inflow of initial rainwater and the filtration of sedimentary deposits; spraying the washing water to each area of the initial rainwater disposal system using at least one or more spray nozzles(23) attached to each pipeline(22); and cleaning up the bottom of the initial rainwater disposal system and removing sedimentary deposits accumulated on the bottom using a bottom spray nozzle. |
