 note = {The water supply business must not only develop and maintain infrastructure for water
supply, but also take measures against infectious diseases. Water supply infrastructure is
aging, and deterioration of water quality will be a concern in the future. Much research
has been done on the replacement costs for aging water supply infrastructure. Similarly,
much research has been done on the effects of aging water supply infrastructure on water
quality.
　However, there seems to be no research that analyzes the impact of deterioration
of water quality with aging of water pipes on crisis management of Japanese water
business. In this paper, we will test the hypothesis whether each water utility in Japan
will strengthen risk management against infectious diseases by the deterioration of water
quality with aging of water pipes.
　The main estimation results obtained in this paper are as follows. First, water supply
businesses that use dams as water sources are mainly self-owned water organizations that
are strongly affected by water shortages and actively take measures against infectious
diseases as crisis management. Secondly, as expected, the water pipeline aging rate was
significantly positive, but some models did not reach the level of significance. There is
empirically a naive side to the hypothesis verification that water quality deterioration with
aging of water pipes has caused for a risk management for infectious disease control in
Japanese water business. Each water utility in Japan is only interested in meeting certain
water quality standards. It is speculated that if the water quality standard is exceeded,
the awareness of risk management will not be strengthened so much.
　Finally, the water supply vision formulation dummy variable has the greatest impact
on decision-making on infectious disease control since FY27. Water utilities that formulate
a water supply vision are conducting risk management for long-term infectious disease
control while considering the aging of water supply infrastructure and the maintenance
and management of water quality. Since the future water business will need crisis
management including Covid-19, Japanese water utility must create a new water vision},
