About "private road measures contracted sewer construction" and "subsidy of joint drainage construction"

　The sewerage facilities laid by Yokohama City are basically intended for public roads, and in principle, the private road part is constructed by everyone who uses the sewerage system.
　However, if certain conditions are met, if you use the system of "Private Road Measures Contract Sewerage Work" or "Subsidy for Joint Drainage Work", Yokohama City will install a sewer pipe on behalf of the user. Or, we will grant subsidies for construction performed by the user.
　About summary of system, please confirm about sewer pipe maintenance in private road (PDF: 282KB).　In addition, please ask each ward Public Works Office for details of each system.
