Results of pilot project (Clarification
effects of TRWKR)■ It was confirmed that the water quality tended to improve
during TRWKR between Sanage Bridge and Matsushige
Bridge.
■ Network of citizens who wish for clarification andrestoration of Horikawa River expanded.
■ Citizens awareness of cleaning of the river was developed.

■ Role of Horikawa Sen-nin Chosatai(Conclusions of Summary Meeting for the 10th Stage)① More surveys should be implemented.
・Continuity of investigation, clarification of thesituation of the river, identification of cause ofpollution in the river, are needed.
・We improve our plan and take action against
the pollution.
・After that, citizens and public administration
do what is possible to clean the river.

②There are many things that citizens
can do.
・We expand our partners who love
Horikawa River and hope TRWKR again.
・We deepen exchanges with people
living in the basin of Kiso, Nagara, and Ibi
River.
・We check the effects of pollution
removal from domestic wastewater andimplement it in each house.

Length: 16.2km(Tidal effect section 13.6km)

Change in temperature, precipitationand hours of sunshine
Cause of breedingofpphytoplankton,
nitorogen andphosphorus areincluded inwastewater fromhouses, factories
andstores.

The primary cause of water pollution is wastewater from houses, factories, and stores.
Wastewater is discharged after treatment in wastewater treatment plant.
●●●

After heavy rain, wastewater isdischarged without treatment.

It has looked like redtide or blue tide.
In Nagoya Port anddownstream ofHorikawa, it is said
that phytoplankton
does over breedingand extinction, so
water basin is polluted

Number of Reports

400 reports
every year

Over 50,000 people joined in Chosatai.
Number of reports is above 4,500 in total.

We got 4536 reports in total by when 20th stage finished.
(April 2007 ‒ December 2016)
Lots of people research the water environment of Horikawa River
continually from a viewpoint and sense of citizens.

102. Report of the 20th stage survey
2.1. Introduction 〜Column〜〜Column〜 History of the Decade of Horikawa Sen-nin Chosatai
Horikawa Sen-nin Chosatai was established at April.22nd.2007, as a place for citizens activities, Fixed Point Observation Group,
Free Survey Group and Support Group, for clarification and regeneration of Horikawa River. We celebrated the decadeanniversary in April.
Fixed Point Observation Group examines Horikawa River with TRWKR, from a viewpoint and a sense of citizen for, confirming theclarification effect, water quality and elucidation of cause of pollution. Free Survey Group studies Horikawa River from various
view points. Support Group supports clarification and regeneration of Horikawa River in various ways. Then the three groups wish
for clarification and regeneration of Horikawa River, and work together in a large network.
Currently(Feb.18th.2017) there are a total of 2,722 groups and 53,418 persons in HSC, 99 groups in Fixed Point Observation
Group, 40 groups in Free Survey Group and 2,583 groups in Support Group. At the time of launch there were 165 groups and2,262 persons. It shows that the network of citizens wishing for clarification and regeneration of Horikawa River has expanded
greatly.
Fixed Point Observation Group observed 4,536 times from 1st stage to 20th stage. So far, we found that the state of the waterchanged from moment to moment due to the influence of the tides, at the downstream from the Sanage Bridge. And we canfound that a lot of observation results from the Fixed Point Observation Group can capture the average state of water quality ofHorikawa River by citizens point of view and sense, and understand the tendency of the change.
〜Social experiment of the clarification of Horikawa River Confirmation of clarification effect of TRWKR from April.2007 to
March.2012 〜
We confirmed that water quality between Sanage Bridge to Matsushige Bridge had been improved by TRWKR(0.4m3/sec.) infive years. And in this period, we confirmed that the garbage (Artificial garbage: plastic type garbage etc.)reduced. It seems thatthe consciousness of the citizen changed, such as the cleaning activity became active.
【Five years summary】■We confirmed clarification effect of TRWKR.
■Network of citizens wishing for clarification and regeneration of Horikawa River has expanded greatly.
■Consciousness of the citizen changed, such as the action of the cleaning activity became active.

Reality and change of Horikawa River has
appeared by angles and senses of citizens.
① Impression of clearness improved on level of citizens life.
We set up suppositions that the new measure improved.
② When the riverbed cleaned, the transparency improved.
We observed the experiment of clarification by covered sand.
③ We experiment in clarification by plants.
④ We set up suppositions of a large death of fish and mechanism of it.
⑤ We rendered the water color with the three primary colors.
⑥ We continue associating with upstream area and studying environment.

1. Weather in 20th Stage(Sep20-Dec16 2016）
More rainy & cloudy days, shorter sunny time and higher temperature than usual in Sep. and Oct. becauseof fronts and typhoons.
Temperature change bigger in Nov. but precipitation and temperature was almost same as the average. In
December temperature was higher and there were some heavy rain.

Summary ： High Temperature, High Precipitation, Short Time of Sunshine
２．Measures for improuvement of water Quality after stopping TRWKR(March 2010)
・Introduction of Advanced water treatment at Meijo Water Treatment Center(May 2010)
・In-service of Horikawa Ugan Rain-water Reservoir for pollution control(September 2010)
We look forward to completion of Horiakwa Sagan Rain-water Reservoir.
・Utilization of reclaimed wastewater at Moriyama Water Treatment Center(August 2011)
4,000m3/day(0.046m3/sec) conducted during irrigation season（Apr.-Oct.）・Making shallow and deep for Improvement of self-purification function and water environment
・Utilization of shallow grand water
Set a new well in the upstream of Nakatsuchido Bridge(March 2016)
・Experiment of covering sand for water purification(February 2015)
We are getting various reports on living things which will be data for knowlege about self
purification of Horikawa River and improvement of water environment.

3. Change of Water Quality
Although water quality worsened after TRWKR, it got better gradually after 15th stage from Sanage
Bridge towards downstream. We believe that change of peoples awareness and government s newmeasures made it.
In the 19th&20th stage impression of water and transparency got worse a little compared to the 17th
&18th stage because of high temperature and high precipitation we guess.
We are worried that global warming and climate change make water quality of Horikawa River worse again.

24

Survey results show that ratio of bubbles from river bed in spring-early summer is higher than autumn-early
winter. Accordingly we built hypothesis below noting relation between bubbles and water temperature.
（see：6.5.Bubbles）■Decrease water wastes(Suggestion)(Hypothesis) When temperature rises,from houses！
ratio of bubbles increases
If temperature of Horikawa falls, bubbles(including H2S) can be decreased?
When bubbles decrease, smells andwhite-colored condition are suppressed.
To stop the global warming and fall watertemperature of Horikawa, citizens can doa lot of things !
Ratio of bubbles from the river bed have relation
to temperature? （see：6.5.Bubbles）

To clean Horikawa,what can citizens do?
To decrease water wastes fromeach houses, what can we do?
To fall temperature of Horikawa
and stop the global warming,
what can we do?

Examples of the mechanism of the occurrence of
bubbles at the river bed（reference） Report from the 13th survey meeting(1)Decrease wastes form kitchen①do not drain cooking wastes andleft-over food②clean bad stains on dishes by
paper and then wash them
③do not drain oil(2)Decrease wastes from laundry①use appropriate amount of highbiodegradability soap orphosphorus-free detergent②set filter to remove lint

■Stop the global warming!
(1)Practice Eco-styleCool-biz, Warm-biz

Higher percentage of Bubbles
have been seen in spring-earlysummer stages(2)Make Green Curtain(3)move eco-friendly
public transportation system(4)Buy energy saving electric
appliance etc.

４． State of Shin-horikawa River
The number of surveys in Shin-Horikawa River was 227 (the 20th stage : 112) at the end of the20th stage. Because of the small number of data, this survey is organized using all data (including the
day before and the rain on that day).
Shin-Horikawa River has a dirty section(Maizuru Bridge 〜 Kinen Bridge) of water in the most
upstream. The ratio of terrible smell , bad smell , smell and slight smell is 84%-94% between
Maizuru Bridge and Kinen Bridge.
Based on the survey results (smell and water colors), HSC believe that the watershed will be like bluetide.
In order to clarify the situation of water quality in Shin-Horikawa River, it is necessary to accumulate alot of data continuously.

5. Change in living things (see 6.9 Living things)

Living things in Horikawa River
Along with the implementation of new water quality
improvement measures, we have learned that the qualityof water is improving from the perspective and sense of
citizens. At the same time, citizen s survey has
confirmed and reported living things such as 16 fish
species, 4 crustaceans, 42 species of birds.
It seems that ecosystems are also recovering, such as
the appearance of growing and breeding depending on
species. I believe that recovery of this ecosystem means
recovery of self-cleaning effect of Horikawa River.
In this report, I tried organizing the frequency of species
confirmation based on the information of living things
recorded and reported by fixed point observation fromthe 1st stage to the 19th stage.
As a result, after stopping the water supply, it was
found that the frequency of confirmation of birds was
kept high in comparison with the first stage and thesecond stage after the start of the water supply, and it
is gradually increasing. We think that this is because theenvironment has improved due to new water quality
improvement measures implemented, such as more foodfor birds.
Meanwhile, the confirmation frequency of fish has notincreased.

When oxygen becomes abundant, living things in thewater do not gather on the surface of the water.
⇒ It getting harder to find them.
