WORKSHOP ON URBAN DRAINAGE ENGINEERING
Basic Concept of Sustainable Urban Drainage Systems (SUDS) and
Engineering Design Issues
BACKGROUND INFORMATION
1.
Recent floods in a number of South East Asian countries left many areas and cities
inundated with water, and inflicted huge damages in these areas. The intensity and
duration of the rainfall in the wet season varies from year to year, but their
occurrence can be well predicted by statistical analysis. Many metropolitans and its
surroundings are rapidly urbanizing, and the land use in the catchments is being
altered too, with many paved roads and asphalted areas that quickly funnel rainfall
into the rivers. These factors, perhaps combined with some climatological changes,
seem to generate floods that are more frequent and of greater magnitude. The
future floods will also induce more damage than those in the past because the city
will have more numerous and more valuable assets.
2.
Many of these metropolitans are the nation’s economic and political powerhouses.
For example, Jakarta is one of the largest metropolises of Asia, and its economy is
thriving and has recovered fast from the Financial Crisis. Although most other
Asian cities are affected by local inundations, Jakarta has a history of vulnerability
to floods, and as suggested, this situation will worsen unless more coordinated
action is taken.
3.
The flood problem is not a new problem. It is caused by numerous, well-known
shortcomings in how cities prepare them self for these events. Only a small part of
the problem is to be attributed to nature: very extreme weather and very intensive
rain that occur only once every 100 or 200 years can create situations that probably
no city drainage system can accommodate. However, the 2002 and 2007 floods in
Greater Jakarta were arguably caused by rainfall that occurs every 5 year, and this
should be easy to accommodate. The original city drainage system was designed to
accommodate river discharges that occur once every 25 or even 50 years.
4.
But now the city’s infrastructure already fails under much less demanding
conditions. DKI and the Provinces and Kabupaten in the Greater Jakarta Region
appear to have several weaknesses in planning and management: in river basin
management, design and operation & maintenance (O&M) of the metropolitan
drainage infrastructure, urban planning and land use management, and also in the
behavior of the public that fails to value the city’s drainage system.

5.
The key is to start managing flood prevention pro-actively rather than reactively.
This means investing resources to reduce the incidence and severity of urban
flooding, instead of paying for clean up after the event; maximizing the
performance of the existing infrastructure, instead of only constructing new
facilities; and encouraging co-operation and “win win” solutions between the
downstream and upstream regional governments.
6.
The problems described above are more or less similar in other flood prone urban
areas in South East Asia, such as Malaysia, Vietnam, the Philippines, etc. A more
systematic approach to flood risk mitigation need to be developed. In Indonesia,
many studies on drainage and flood have been and are being carried out. Modern
technologies allow developing more sophisticated methodologies to flood risk
mitigation. During the 3rd SEA Water Forum a side event is devoted to the flood
problems in South East Asia.
7.
At this point knowledge sharing between the CKNet members on urban drainage
engineering, through workshops, conferences and short courses may be considered
as part of CKNet mission in water resources management in Indonesia. CKNet will
conduct a series of short courses for selected participants from CKNet members
concerned with urban drainage. This course is devoted to Urban Drainage
Engineering.
COURSE CHARACTERISTICS
Course Description:
8.
This course is a course on the basic principles of urban drainage planning,
engineering design and implementation, taking into consideration the environment
and urban spatial planning in order to arrive at sustainable urban drainage systems.
Aim of the Course:
9. To train participants how to develop a sustainable urban drainage plan, hydraulic
design of the urban drainage systems and implementation issues. It includes aspects
of proper Operation and Maintenance of the system. A sustainable urban drainage
system brings in the principles of integrated approaches to reduce flood risk in
urban areas. The course provides insight into the tools and techniques required in
the process.
Course Context:
10. The course will be focused on the planning and engineering design of Sustainable
Urban Drainage Systems (SUDS) that have been conceived to satisfy the ecologic,
social and economic aspects of sustainability.
Course Structure:
2
Workshop on Urban Drainage Engineering
11. A blend of classroom activities, group discussions, exercises and assignments
focusing on the skills to apply the SUDS principles in water resources and irrigation
management.
12. The training will refer to academic topics, institutional setting, personal skill
development and topics relevant and taking into consideration the future Indonesian
Water Sector under the new Indonesian Water Resources Law UU 7/2004.
Learning Targets:
13. After successfully completing the course, the participants will
a) Be able to describe the concept of SUDS and its main principles;
b) Be able to describe the main issues to be addressed in an SUDS strategic plan in
Indonesia;
c) Understand the relevance of strategic programming and planning to SUDS;
d) Identify the main stages in the programming and planning cycle and understand,
in a general sense, what they mean in the context of sustainable management of
urban drainage systems;
e) Appreciate the different activities and the scale and scope of actions required to
develop an SUDS plan;
f) Understand the basic hydrology and hydraulic principles of urban drainage
systems;
g) Understand the main factors in the implementation of a SUDS strategic
planning process;
h) Be able to identify strategies required to plan and implement proper operation
and maintenance activities of the systems;
i) Be able to identify the different methodologies for urban drainage technologies
and be able to describe the advantages and dis-advantages of the various
systems under a certain condition;
j) Be able to design a simple SUDS plan for an area, including construction of the
infrastructure and O&M issues.
Suggested Syllabus:
14. It should be noted that the topics of the course should be addressed from a
professional approach, and not be limited to theories and academic approach only.
The learning targets specified under point 13 should be used to develop the details
of the syllabus, exercises, individual and group assignments, etc.
15. A suggested syllabus is given below. All the components in the syllabus should
form an integral part of the course. The course provider is free to adjust according
to their experience in development and delivering similar courses.
