To provide a water supply maintenance method capable of performing an operation of replacing an existing elevated water tank with another elevated water tank while maintaining the water supply.SOLUTION: The water supply maintenance method of the present invention being a water supply maintenance method at the time when an elevated water tank 200 is replaced, comprises steps of: supplying a rear-stage water supply pipe 40 with water via a detour pipe part 70 while supplying the rear-stage water supply pipe 40 with water from the elevated water tank 200 and connecting a front-stage water supply pipe 10 and the rear-stage water supply pipe 40 by the detour pipe part 70; replacing the elevated water tank 200 with a different elevated water tank 300 after stopping the circulation of water from the front-stage water supply pipe 10 to the elevated water tank while supplying the rear-stage water supply pipe 40 with water via the detour pipe part 70, and resuming the circulation of water from the front-stage water supply pipe 10 to the different elevated water tank 300 to supply the rear-stage water supply pipe 40 with water from the front-stage water supply pipe 10 via the different elevated water tank 300; and removing the detour pipe part 70 after stopping the circulation of the water of the detour pipe part 70 while supplying the rear-stage water supply pipe 40 with water via the different elevated water tank 300.SELECTED DRAWING: Figure 4
【課題】既設の高架水槽から別の高架水槽に取り替える作業を、給水を維持しながら行うことができる給水維持方法を提供する。【解決手段】本発明の給水維持方法は、高架水槽２００を取り替えるときの給水維持方法であって、高架水槽２００から後段給水管４０に給水しつつ、迂回管部７０により前段給水管１０と後段給水管４０との間を接続し、迂回管部７０を経由して後段給水管４０に給水する工程と、迂回管部７０を経由して後段給水管４０に給水しつつ、前段給水管１０から高架水槽２００への水の流通を停止させてから別の高架水槽３００に取り替え、前段給水管１０から別の高架水槽３００へと水の流通を再開させて前段給水管１０から別の高架水槽３００を経由して後段給水管４０に給水する工程と、別の高架水槽３００を経由して後段給水管４０に給水しつつ、迂回管部７０の水の流通を停止させてから迂回管部７０を取り外す工程と、を備える。【選択図】図４
