RECLAMATION & GSW

St Petersburg Russia, Palm Island Dubai, Netherland, Duriangkang Dam, Jakarta Bay Indonesia

Reclamation dan Giant Sea Wall

(GSW) If we need it and the impact is

measureable, Reclamation and GSW are

not taboo.

But 17 Reclamation Islands and GSW in

Jakarta Bay are Wrong Concept and must

be stopped

GSW and Reclamation are not Solution

17 Reclamation Islands are Big Mistake

Sedimentation at the mouth of rivers

Huge Pump

Total 3000 m3/det?

Water Level must be lowered to

reduce the size of Pump

GSW must be build

Giant Seawall is not Solution of Jakarta

Land Subsidence

Huge Operational Cost and Huge Impact

Coastal and River Protection along

Land Subsidence Area

We still need Coastal Protection although GSW is build

Strengthen Coastal and River

Protection, Jakarta only pump the

water rainfall in Land Subsidence

Area

Jakarta must pump the water

rainfall in (Cipanas, Bogor, dst.)

+ Land Subsidence + Reservoir

Flow Averages

730.000.000/3.600/6/24 = 1.400 m3/s

Flow Maximum ~ 3.000 m3/s

Jakarta don’t need Large Waduk if the

river flow are not blocked

Basic Concept of Reservoir

Flow InFlow Out

Pump

Elevation Change

Elevation Change x Area = Flow In – Flow Out

NCICD Water Pump is too Small

Reservoir Analysis

Flow Out = 730x3600x24x6 = 378 million m3

Flow In = 730 jt m3

Area 75 km2 = 75 jt m2

Water Fluctuation = 4,7 meter

What will happened if Jakarta has Power

Supply?

Small Pump

The Biggest Pump in

the World

Same Size waduks in city to

store storm water

No need to pump River Flow

from Upstream

Sea wall 3.8 to 5.8 meter

River Banks 3.8 to 5.8 meter

Giant Sea Wall

25 meter

Giant Pump

All urban water +

River Flow from

Upstream

All urban water must be

pumped out

Smaller Waduks???

Jakarta must improve River Water

Quality before constructing

Giant Sea Wall

Separate Drainage and Sewer

Build Sewerage Treatment Plant

Conclusion and So;ution There is no threat from the sea

GSW Jakarta is not solution of Land Subsidence

Reclamation will block River Flow

GSW Jakarta Operational Cost is huge

GSW Concept of NCICD must be stopped

Strengthen Coastal and River Protection, Jakarta pump the water rainfall in Land Subsidence Area.

Separate Sewer and Drainage

Build Sewerage Treatment Plant

Jakarta Solution

Strengthen Coastal and River Protection,

Jakarta pump the water rainfall in Land

Subsidence Area

Separate Sewer and Drainage

Build Sewerage Treatment Plant

Zero Runoff
