Vol. 187 Will the sewerage fee system change due to population decline?

On January 29, the Ministry of Land, Infrastructure, Transport and Tourism held the third meeting of the "Study Group on Sewer Management in the Era of Maintenance and Management Under Population Decline." I looked into what topics were discussed in the first two meetings. In the water supply business, due to the spread of water-saving devices and population decline, the amount of water sold has been on a downward trend since peaking around the year 2000, and it is projected to decrease to about two-thirds of the peak level by around 2050. Smaller organizations in depopulated areas with fewer residents in the service area are forced to charge higher fees, while larger organizations with more residents in the service area are managing well, with fee levels significantly below the requirement of 3,000 yen (per month/20 liters) for financial measures.
