1. JICA TRAINING COURSES RELATING TO SEWAGE WORKS
Stormwater Drainage Technology with Sewerage System II
Organized by Osaka City Government
Mr. Kazuhiro Kusakabe
JICA Training Course, "2003 Sewage Works Engineering III" organized
by SBMC in close cooperation with MLIT, Ministry of Land Infrastructure
and Transport, and JS, Japan Sewage Works Agency, was successfully
finished on Nov. 28, 2003 with "Course Evaluation" and "Closing
Ceremony", and each participant has returned to the country.
Before that, on Nov. 26 and 27, "Case Study", in which each
participant made a presentation about the result of the consideration
for the solution to each country's problems and investigation for
the proper way to promote the sewage works based on the information
and knowledge gained in the training course, was conducted.
Each presentation was well considered, and it was thought that this
experience was very helpful for future.
Besides "Sewage Works Engineering III" Course, there are several
training courses relating sewage works, which are implemented by JICA.
They are "Stormwater Drainage Technology with Sewerage System II"
managed by Osaka City, "Operation and Maintenance of Sewerage
Facilities II" managed by Sapporo city, and so on.
From this issue, SBMC Newsletter is also provided to the
ex-participants of these courses, and the outline of these courses
will be reported in the Newsletter.
In this issue, Mr. Kazuhiro Kusakabe, Officer of Osaka City Government,
reports outline of "Sewage Works in Osaka City" and "Stormwater Drainage
Technology with Sewerage System II".
-------------------------------------------
1. Sewage Works in Osaka City
Osaka City lies roughly in the middle of the Japanese Archipelago.
The City has a total area of about 220 km2. Although the City has a
residential population of 2.6 million, its daytime or workday population
reaches 4 million; Osaka City is one of the largest cities in Japan.
At present, the sewered population rate is nearly 100%; almost the
entire area of the City is served by the combined sewer system.
Osaka City Government operates 12 sewage treatment plants with the
total capacity of 2,844,000 m3 per day, and pumping stations,
capable of discharging stormwater into rivers and the sea at a rate
of 1,280 m3 per second.
In Osaka City, however, due to rapid urbanization in recent years
with reduction of rain water permeable area by increase of roads,
houses, buildings, etc., stormwater runoff has increased, resulting
in increased occurrence of flooding.
To prevent flooding, we have been working on several projects
including the construction of large-scale trunk sewers and pumping
stations. One of the major construction projects for stormwater
runoff control is Naniwa Grand Floodway construction project
consisting of Suminoe Pumping Station with a design drainage
capacity of 75m3/s and 12.2 km long trunk sewer with maximum
inside diameter of 6.5m. This project was completed in 1999, and
commenced full-scale operation in April, 2000.
There are other projects under construction, and the Osaka City
Government is currently going forward with the improvement of its
sewerage system emphasizing on flood control as well as the
conservation of water environment.
Other Major Projects
Tosabori- Tsumori Trunk Sewer
Pumping Station (Capacity 87m3/s)
Trunk Sewer (Total Length 6.7km, Maximum Inside Diameter 6.25m)
Targeted Completion Year: 2004
Yodo Grand Floodway
Pumping Station (Planning Capacity: 105m3/s)
Trunk Sewer (Total Length: 22.5km, Maximum Inside Diameter: 7.5m)
Trunk Sewer Construction was started in 1991, and the complete
section has been utilized for stormwater reservoir(capacity 5000m3).
2. Stormwater Drainage Technology with Sewerage System II
Since 1991, Osaka City government has organized JICA Technical
Training Course, "Stormwater Drainage Technology with Sewerage
System II" for sewerage engineers working for central/local
governments of developing countries.
The course is held between early September and the middle of November
every year, and the total number of participants by 2002 amounted to
79 from 25 countries.
This training course features lectures given by experts from the
Japanese government, universities, Japan Sewage Works Agency, and
Osaka City, a variety of hands-on practice sessions under the
instruction of Osaka City officers, and field trip.
The objects of this course are to
1. acquire basic knowledge regarding the improvement of sewerage
systems
2. understand basic factors and planning methods regarding stormwater
drainage
3. acquire knowledge regarding the planning, design, construction,
and maintenance of sewers, pumping stations and other related
facilities used for draining stormwater
4. acquire knowledge about stormwater information processing
systems, and
5. understand pollutant load control methods by water quality
management and industrial wastewater control
This training program enables trainees to acquire extensive skills
and knowledge relating to sewerage system development and especially
srormwater drainage.
Through the provision of JICA Training Course, we have decided to
contribute to progress in resolving increasingly serious global
environmental issues. We hope that you will read the SBMC
newsletters and develop an interest in our activities.
A brochure containing detailed information on sewage works in Osaka
City is available in English. To request it, please send an e-mail
to ma0008@ii.city.osaka.jp along with your mailing address.

2. INFRASTRUCTURE INTENSIVE DEVELOPMENT PLAN
Newly Aimed Outcome for Sewerage Works in 2007
Infrastructure intensive development plan which covers long term
plan from 2003 to 2007 for transportation facilities like roads,
airports, harbors, and railroads, rivers, parks, etc. as well as
sewerage facilities, was formulated by cabinet on Oct. 10, 2003.
In this plan, the basic policy for sewerage facilities was settled to
promote sewage works intensively and systematically giving attention
to citizen's viewpoint for public works, watershed management,
cooperation with various organizations, effective management of
facilities, and measures for internationalization.
So far, long term plan was made in each facility, and emphasis
was put on project budget. However, in this plan, the chief aim
is put on the outcome for each project. It is also decided to collect
citizen's opinion and ask local government's opinion to reflect them
to the project. In addition, project evaluation will be conducted
every year.
Principal objects and target outcome in each field were set up.
In the field of sewerage works, five principal objects and relating
target outcome were decided.
For instance, regarding the first object, "Ensuring the comfortable
and hygienic life", sewered population rate as a target outcome
in 2007 was set to be 72% while the actual rate in 2002 is 65%. Also,
regarding the fourth object, "Reduction of the load to environment
mainly based on the circulation", recycling rate of sewage sludge
in 2002 was 60%, and target outcome was set to 68% in 2007.
For details of this plan, please visit following SBMC Home Page and
check the newly aimed outcome for sewage works in 2007.

3. REPORT FROM PARTICIPANT IN 2003 SEWAGE WORKS ENGINEERING III
Following the previous newsletter, we provide the report of each
country's participant in 2003 Sewage Works Engineering III Course.
In this issue, reports from participant in Bangladesh and Guyana
are described.
3-1 Mr. Shadhu Khan Tushar Mohon
from Bangladesh
Proper Sanitation is the severe problem in Bangladesh.  It is
estimated that about 57% of the total population is now using
hygienic latrines, compared to just 10% in 1989 and 20% in 1995.
On the other hand, all the cities of the country have some sewer
system but it does not enough compared to the city area.
The sewage collection and treatment of Dhaka city is quite
different from other areas of the country but not adequate as
it required. In Dhaka city, we have one sewage treatment
plant constructed during 1989 to 1992 at Pagla with the
assistance of Japanese Government.
Bangladesh, one of the most populous country of this region, is
trying to arrange the basic amenities like potable water supply,
sanitation and wastewater management.  To achieve the goal and
to ensure that development in the water supply and sanitation
sector is equitable and sustainable, the Government of Bangladesh
formulated National Policy for Safe Water Supply & Sanitation, 1998.
Standards of domestic sewage and industrial effluent to be
discharged in the public water bodies are also to be determined.
In order to introduce effective wastewater management, wastewater
policy and its legal framework for implementation are to be
formulated very soon.
Under these circumstances, it is the great opportunity for me to
attend this Sewage Works Engineering III course organized by JICA.
In this course, besides the lecture, we got the chance to visit
several large cities in Japan and see wastewater treatment
facilities.
All the cities where we have visited, do have their specific and
individual sewage treatment facilities, and also they adopted some
modern new technologies, which make me quite surprise.  Especially
in Munakata city in Kyushu, we saw the advanced wastewater treatment
plant using the Immobilized Nitrifier in the aeration tank.
In Fokuoka city, they are using recycled wastewater as flashing
toilet. These types of technologies might be adopted in our country
where water is not easily available for all purposes.
Today's world has become very much concerned about limited water
resources. We must project these invaluable resources for the
sake of our existence. So, efforts should be given to achieve the
proper sanitation and sewerage treatment facilities.
In this respect, I think that these valuable knowledge and vast
experience gathered attending this Sewage Works Engineering III
course makes me beneficial and useful to upgrade, improve and
renovate sanitation and sewerage treatment facilities in my country.
Staying in Japan for three months has become unforgettable
experience for me.

3-2 Mr. Mark Mendonca
from Guyana
My name is Mark Mendonca and I live in Guyana. My country is
located in Northern South America, bordering the North Atlantic
Ocean between Suriname and Venezuela.
Guyana is an Amerindian word meaning "land of many waters". This
name was originally given to the territory on the north east of the
South American continent, which is drained by several large rivers;
the most important being the Amazon, Orinoco, Demerara, Berbice,
Essiquibo and Corentyne. From this territory five (5) Guianas
emerged, of which my country is one.
I am a Mechanical Engineer working for the Guyana Water Incorporated
(GWI), the single water utility in Guyana. My company is responsible
for the operation and maintenance of the water distribution networks
and plants, and the existing sewerage systems within Guyana.
GWI comes under the Ministry of Housing and Water.
My present role within GWI as an Asst. Divisional Manager is to
ensure the operations and maintenance of distribution networks,
pumping stations and treatment plants within one region is carried
out efficiently. There are two sewerage systems in my country
(population served: 250,000) and there are no treatment plants.
Over the years water supply and improvement of sanitation has
become a major issues in all developing countries. Guyana is no
exception, and unfortunately in Guyana the sewerage section has
been overlooked and has suffered from under funding. However,
the water and sewerage sectors are now merged, and plans are
underway to improve the current situation.
Coming to Japan on this training programme, Sewage Works Engineering
III, is a most valuable experience for me. The technical training
and the cultural exposure so far has been a shock and more
specifically it has been educating. The welcome and the hospitality
of the Japanese so far have been exceptionally great.
In my country, there were lots of participants in JICA training
course, especially in the water and sewerage sector, and I would
like to thank the relevant agencies for providing these special
training to build a brighter future for my country. On my return,
I hope to work closely with the sewerage sector in rehabilitating
our sanitation and sewerage systems.
