Do not pour dirty water into rivers or road gutters

　The water in the rivers in Inagi City has become cleaner than before due to the spread of sewage systems and increased citizen interest in environmental issues. There are also many water facilities along the riverside, which are used by many people as a place to relax.
However, accidents frequently occur in which paint, oil, cleaning and car wash detergents, and tree disinfectants flow into rivers.
　
　We ask for the understanding and cooperation of all citizens in order to maintain a good waterfront environment.

　Basically, Inagi City uses a "separate sewer system" that separates rainwater and household wastewater.
Domestic wastewater passes through sewage pipes and is treated at a water reclamation center.
On the other hand, rainwater is either allowed to permeate underground in rainwater basins, or is discharged directly into rivers through rainwater pipes from roadside gutters (some rainwater basins are connected to rainwater pipes).
Therefore, if you pour dirty water such as paint into road gutters or rainwater drains, the dirty water will flow directly into rivers.

(Please note that in facilities that use a separate septic tank, wastewater other than toilets is discharged directly into rivers or irrigation canals.)

• Use up all oil, paint, etc., without leaving any waste liquid.
• Let's properly dispose of leftover paint and dirty water from washing brushes as waste by soaking them in rags or paper.
• Wash your car at a car wash, etc., and prevent washing wastewater from flowing into the river.
• Make sure you know the required amount of disinfectants for trees, etc., so that the spray solution will not be left over. In addition, wash in an appropriate place so that the washing water of spraying equipment and containers does not flow into water systems such as rivers by mistake.

　Water quality incident treatment should originally be the responsibility of the person responsible, but since urgent and accurate response is essential to avoid the spread of damage, river administrators and other related organizations should directly clean up the incident. There are many cases where measures such as these are implemented.
However, even if a river administrator takes measures to deal with an accident, the person responsible for the accident must bear the costs and expenses required for such measures. (Article 67 of the River Act)
