OUR RIVER #WHAT IS RIVER riv•er \^ri-v^r\ noun a large natural flow of water that crosses an area of land and goes into an ocean, a lake, or another river.

Furthermore, river may be refer as territorial integrity of water resources management in one or more of the watershed and/or small islands covering an area of less than or equal to 2000 km2 (UU No. 7 Tahun 2004 tentang Sumber Daya Air).

In general, natural stream of water that flows in a channel with more or less defined banks.

Rivers play a major role in the hydrologic cycle and in shaping the Earth surface. The river is an ecosystem consists of main elements of vegetation, soil, water, animals, and human. As an ecosystem, there are interactions between all the elements that create a balance.

According to Peraturan Pemerintah No. 35 Tahun 1991, river or watershed is a water flow of natural and/or artificial drainage network from upstream to estuary, with a limited setback.

River is one of the greatest assets of a city.

The river is where people live, work, and play.

The interaction between river and people is beneficial to one another as river is a source of transport, irigation, and power.

6

The river is a source of water for life on earth.

Human, animals and plants need water to be able to survive.

A river is an habitat for aquatic biota creating a nature balance.

by Kapitein der Chinezen (head of the Chinese in Betawi), Phoa Beng Gan. He collected toll payments from ampans that passed through.

The name comes from the word molen Molen Vliet which means ‘wheel’ and Vliet which means ‘stream’. On the right side of the canal, there are many sugar milling industry, wine production, and munitions manufacturer equipped with water wheel. Therefore, this region is called Molenvliet or “Flow Windmill”.

Molenvliet made to be a means of transportation of wood, brick, and other materials for

Small boats sailed along Ciliwung to transport goods from warehouses close to Kali Besar to ships anchored at the port.

The canals of Batavia experienced sedimentation.

In order to deal with this, an 800 m long ditch was constructed to the sea that was routinely dredged to ease the flow of water.

1699

Earthquake

Caused the increase in sedimentation level. Heaps of mud and sand accumulated in the ditch that was dredged to ease the flow of the water to and from the river.

1689

Drinking Water The river water was not yet polluted and could be used for drinking water

The river water was considered unhealthy because of rubbish and the waste from the Binnen Hospital discharged into the river. Many patients suffered from dysentery and cholera. The unhygienic drinking water caused high death rates among the Batavia citizens.

The Banjir Kanal was constructed The water flowing along o divert the water of several the Molenvliet still kind that rivers of Jakarta, which includes is used for washing clothes, Ciliwung, Cideng, and Krukut. bathing, and defecating.

The fluctuative rainfall intensity could be the one of the reason for runoff mutation of the City. But the main cause is that the city keep losing its potential infiltration surfaces because of the rapid developement for the last two decades.

The major increasing of runoff cause river overcapacity which it give back the runoff as the cause of flood.

NON-PHYSICAL

Seeing the alarming situation, a number of children in Condet, East Jakarta established a forum for the Environment Community of Ciliwung River, Condet. With the motto : A thousand lives tree. The young people who led this forum, Budi Setija and Muhamad Abdulkadir, has securing around 20 hectares in the Ciliwung riverbanks Condet.

Ciliwung Institute is a forum initiated to facilitate the activities of the community engaged in efforts to save Ciliwung watershed. The scope of activities is also wide ranging from the Peak District of Bogor, Bogor city, Bojonggede, Bogor District, Depok to Jakarta.

This forum was constructed from a variety of issues and trying to raise the potential of Ciliwung from different perspectives. This diversity is a strength that allows the Ciliwung Institute to create interesting activities, so the rescue campaign voiced for Ciliwung become more simple and accepted easily by people.

PHYSICAL

This is Ciliwung riverbanks condition around 1970s in one area of East Jakarta; water flows down swiftly, river remains wide and deep, while the surrounding trees are very dense . Nowadays, it is hard to find such a river bank. Because more and more river bank inhabited by humans as a residence. Even many of them have become slums with a very poor sanitary and very damaged environment. Not surprisingly, the 13 rivers that flow in Jakarta becoming more shallow and smaller from time to time.

Flooding was widespread in every single moment.

KOMUNITAS CILIWUNG CONDET Urban Guerrilla has initiated a series of workshops on a variety of subjects related to urbanism branded as the ‘5 TACTICS OF URBAN GUERRILLA TO OVERTURN THE CITY‘. As the name implies, there will be 5 workshops/projects with 5 different themes in the span of the next two years.

This book will talk about the second project that was conducted in Surabaya

on the 7th-8th of December, 2013. The theme of the workshop was ‘Park’. This event was divided into 2 acts: the first act was to build a garden that involved the local community with Urban Guerrilla as the main coordinator, and the second was a short discussion about macro frame work in “Water Harmonization and Surabaya City” with Tunas Nusa Foundation as the main coordinator.

I HAVE A DREAM...

I still remember my childhood memories, when I spent hours playing in the river with my friends. That was the main reason for me doing all this things. We should fight for a better future for our children; we should make sure that they will still have the river like I had in my childhood.

When I was a kid, when I was playing in the river, my parent asked me to catch prawns first. I thought, why should I look for prawns first? But eventually I realized that we were taught to play safely in the riverbank.; to prevent ourselves from drowning.

We believed that the river has its own melody and children can understand it. So, there is no way a child can drown.

During the exploration of almost 1 km along the Ciliwung riverside, from KCC to the Tectonica Garden, issues and potentials were found related to runoff issues and also people behaviour on the riverbank. For the runoff, we found varians of how it passed from the city to river. Some using natural and some structural and others are hidden pipe.

And people behaviour also quite varies, from making riverside as garbage bank, into use it as playground, sport and leisure area.

“PERSPEKTIF”

INUNDATION

#3

In the middle of June, Urban Guerrilla was invited to Perspektif, a tri-monthly discussion forum hosted by Komunitas Ciliwung Condet (KCC), to initiate and accommodate aspirations from communities along Ciliwung riverbank.

The communities, which vary from activists, local artists, academics, local NGOs, researchers, and KCC itself, are gathered with their common concerns on the conservation of Ciliwung River.

30

The discussion was held in KCC’s base camp, a lush oasis in the midst of a densely populated urban environment adjacent to the river in Condet, East Jakarta, where we still can find big trees and salak Condet plantings. The event was also attended by representatives of BPBD (Badan Penanggulangan Bencana Daerah), Ministry of Forestry, Ministry of Public Works, LIPI (Lembaga Ilmu Pengetahuan Indonesia) and IPB (Institut Pertanian Bogor). The focused topic of the discussion was on Ciliwung River normalization, an undergoing project run by Ministry of Public Works that include the embankment of the 19 km of Ciliwung riverbank along Manggarai – TB Simatupang river edges with concrete. The communities are criticizing the project because of the lack of feasibility study and government transparency.

Perspektif’s agenda included research study

presentations done by students of Ryerson University of Toronto, in collaboration with SMART from University of Wollongong, Australia.

A full day discussion, which contained three main presentations based on various scales and perspectives on the issue: the large-scale perspective covering the approx. 90 km of Ciliwung River from the upper stream to the lower stream; the mid-scale 19 km, particularly related to the Ciliwung Normalization project; and the small-scale perspective focusing on the socio-economic of the kampongs along the river.

The event began with a performance by a local artist playing a unique traditional music instrument “Karinding”, and the discussion was successful with full engagements by the audience.

The first panel that involve a perspective on the larger scale of Ciliwung River described how water flow through the whole Ciliwung River.

It showed that the capacity of Ciliwung River cannot seem to be able to cope with the flood issues anymore due to the high development in Jabodetabek area. Ciliwung River has been in a vulnerable stage, which is contributed by three factors: GLOBAL, POLICY, and LOCAL. The global warming causes climate change, which leads to the increase of rainfall intensity; while in policy, the government stays unresponsive to any urban development policy violations that cause land degradation in area along the river. Those are not to mention the behavior of the local inhabitants, who still regard the river as their back of the house, which is creating worse condition throughout Ciliwung River. The presentation ended with questions delivered by the forum: How the governments manage to do the normalization of Ciliwung River, while the project is also related to many stake holders?

After having tasty lunch of local cuisine, we continued to the mid-scale perspective analysis presented by another student group

from Ryerson University. In this scale, they were focused on the material configuration of the river bank along the 19 km proposed for concrete embankment. From their three weeks of observation and studies, they found six elements spotted in different locations such as soil, stilts, foundations, high rise buildings, walls, and also garbage. At the end of presentation, this team also left with questions regarding the normalization project: How does the normalization affect the natural condition along the riverbank, and how to evaluate the transformation of the materials/elements?

We finally came to the final presentation about Kampong-scale perspective. They observed two kampongs adjacent to Ciliwung River that might be evicted by the government due to normalization project. They are Kampong Pulo and Bukit Duri, which might be the most affected both socially and economically. The also concluded with questions, such as: Has the government done an analysis about this? Has the government consult them about the project?

As many people depend on Ciliwung River, we should criticize this issue from many different perspectives. Does this project worth the budget spent considering the socio-economic challenges that may rise? How does normalization affect the natural and urban system condition of Jakarta?

Could we put the people as part of the solution?

We are not necessarily against the government, as we know that they are trying to prevent the flooding problem in the city. However, we see that it would be more effective, if the government initiate to sit together and discuss with the people on their programs and consider what the people aspire to.

RECOMMENDATION # HOW Urban Guerrilla has initiated a series of workshops on a variety of subjects related to urbanism branded as the ‘5 TACTICS OF URBAN GUERRILLA TO OVERTURN THE CITY‘. As the name implies, there will be 5 workshops/ projects with 5 different themes in the span of the next two years.

This book will talk about the third project that was conducted in Sungai Ciliwung, Jakarta on the 30th of August, 2014. The theme of the workshop was ‘River’. This event was divided into 2 acts: The first act was a survey along the Ciliwung river and the second act was a group discussion between Komunitas Ciliwung Condet (KCC) and local community with Urban Guerilla as the main coordinator. This discussion was using a participatory planning method to let the local community more participate actively to give their opinion about Ciliwung river.

After collect all data that talks about problem, potention, and solution of Ciliwung river, the coordinator finally conclude some methods that possible to be used to solve the problem in Ciliwung river. After long discussion with KCC and Warga Ciliwung Condet, we possibly to use some empty space on the river side near Komunitas Ciliwung Condet places to make some bioswale and water tank to filterize the water that flows from land to the river. This action is a pilot project that has to be applied to filter ize the water that flows into the river. If there will be some additional places (along the river) apply this action too, it is not imposibble for us to have a cleaner river.

Come with basic knowledge of how water runoff works, the team expanding the the ideas within engagement of people tought. Kids and teachers from schools around KCC are invited to speak their mind about Ciliwung. Divived on 3 stages of discussion; ISSUES, POTENCIES, and SOLUTIONS. The asked to write down things they remember, they concern and they got in problem with related to water runoff around their houses.

The enthusiasm of the kids to talk about water and the river are beyond expectation. some with dreams some are so tactical and some with their simple solution talking about how to capture rain from their own houses. After pinning-up people thoughs, the discussion begin to be more verbal to between UG team, people and KCC who concern more about river preservation.

SOCIAL MAPPING ISSUE

POTENTIAL

IDEAS

THE IDEAL OF RUNOFF SYSTEM Runoff is the flow of water that occurs when excess water from rain, meltwater, or other sources flows over the earth’s surface. This might occur because soil is saturated to full capacity, or because rain arrives more quickly than soil can absorb it. Surface runoff is a major component of the water cycle. It is the primary agent in soil erosion by water.

Before there was still no huge development and there still a lot of natural vegetation along the river edge, river could accomodate the run off as much as 10% of water runoff since the rest had been absorbed by the soil.

But, nowdays when there is a lack of natural vegetation and increment of city development, the runoff is increasing as much as 55% and it can’t be accomodated by a river. This is the beginning of river overcapacity that causes flood.

WHEN EVERYTHING IS BEING THROWN AWAY TO THE RIVER...

WE ARE PARTICIPATING TO CAUSE

FLOOD ..AND SOCIETY HOUSING WASTE IS DUMPED INTO IT There are many factors that makes the river becomes overcapacity.Trash that are being thrown into the river accumulate in the bottom level of the river. The river water eroded the edge of land and its soil sedimented in bottom level of the river. This sedimentation decrease the river capacity to collect the runoff. This is the reason why flood happens especially in rainy season.

.. AND THE RIVER IS GETTING

ANGRY TO US!

L HE

!

P!!

So,

What Can We Do?

Attitude We have to treat our river as if it is part of our own front yard. So we always want it to look beautiful and clean. Because how we treat our environment shows who we really are.

Runoff Keep rain water Runoff from flowing straight to the river. So that it can be absorb to the ground water table and used as clean water resource. Any black or grey water need to be treated until it reaches certain quality before entering any public drain or River. Bio filtration system is one of the environmentally sound efforts than can be implemented

48

Flood

Mitigation Non structural and structural efforts are needed as part of flood resilience strategies to insure people’s safety. A few measures that can be implemented: protection levees or embankment and periodical dredging, policy warning system and preparedness.

49

Attitude By changing our view point of view, we will be able to build our respect towards the River.

Instead of treating it as our public latrine, we have to think river as our gateway to our community where our guest feel, welcomed as they pass through

Sustainable Runoff Management 52

Do you

Know?

Jakarta receives about 1,855 mm of rainfall annually. It is important to have an effective stormwater management system to ensure a cleaner water supply in Jakarta’s reservoir.

It could be combined with waste water management system in order to help to capture and treat the water before channeling it into our reservoirs through the drains and canals.

How to reduce runoff from our home?

1

On-site Stormwater Storage

We can store the rain water in barrels and use it for irrigation; the rest are flow through the swale or rain garden

COLLECT RAIN WATER

USE GREY WATER SYSTEM

Instead of waste directly to drainage, we can re-cycle and re-use the bathwater, hand basin water and washing machine water to flush toilets, car washing and garden irrigation

PERMEABLE PAVEMENT

Permeable asphalt, concrete, or paver blocks allow water to seep into gravel and soil below

Flood Mitigation

The community problem not only about giving water to canal or river uncontrolly. But also on the other way around, the river eventually giving back the overload water to the city because of riverbank form degradation and also sedimentated solid waste underneath the water. One simple recommendation is to build a water barier on the riverbank, not only to prevent water overflowedback but to sustain the riverbank form.

River accumulates silt as flow slows down (more silts after an extreme flood)

Flood by sedimentation But, we can prevent flood by using the combination of berms and gabions

60

During heavy rain, river floods

WHAT should we DO? Berm s

Berms are could be used to control erosion and sedimentation by reducing the rate of surface runoff. The berms either reduce the velocity of the water, or direct water to areas that are not susceptible to erosion, thereby reducing the adverse effects of running water on exposed topsoil.

RECOMMENDATION

MAPPING

Based on local exploration, the best way to reduce run off is to capture it before goes directly to river. Varies exisiting water disposal system drive to varies solution on water treament before go to the main banks which also appears in varies.

THE PILOT PROJECT As an example of a more detailed implementation.

We design one part of the whole system.

This part consist of Soil trap, Bioswale and Water tank. The design implementation will be located around the KCC premises, at the flood plain area. The function of this part is to catch the trash that flows with the run off and absorb the run off water along the swales. the over flow or the remaining water run off can be contain in the water tank

LITTER TRAP

BIOSWALE

The spot which appear as the highest runoff found in location inside KCC is the spot where the treament might work its best.

The main idea to capture water implemented by using a solid fiber water tank planted on ground within the overflow directly to the river.

In hope tha the captured water will be usefull for community for daily life as non-potable water, and the the project will be spot for people about how wastewater can be usefull.

THE DETAILS All suggested materials are the standards to create bioswale that performs well. Any other local materials could be replacing their role as long as it configured the same.
