Conservation of groundwater

Groundwater is an important property

Niseko is blessed with abundant snow cover and rich forest. With the benefits of nature, clean groundwater can be used as drinking water indispensable to our lives. However, groundwater is also a limited resource, and there is a danger of causing drought and ground subsidence by sampling a large amount of water.
Groundwater is an important shared property indispensable to everyone's life. It is required to give consideration to each other and to use it moderately.

Permission and notification of well drilling

In order to prevent drought and land subsidence due to excessive water sampling, Niseko Town requires permission or notification before drilling a well to collect groundwater based on the Niseko Town Groundwater Conservation Ordinance.
The flow of permission and notification is as follows.
