Dutch Water Management
National Policy
Retention
Obliged: New houses must retain water
Existing: Stimulated to retain water
Governments uncouple complete areas
1
Traditional Solution:
- Plastic crates
- Concrete boxes
Issues:
- Limited lifetime
- Difficult to construct
- Not flexible in design
- If cover fleece broken ->
reduced volume
- Air trap & smell
- Maintenance intensive
- Storage but no retention
Storage
2
- wadi
- reservoir
- pond
- flood plane
Issues:
- Available space
- Musquitos, rats, algae,
waste, etc
- Safety (children)
- Maintenance (mowing; cleaning)
Discharge
3
- Urban: Piped storm water discharge system
- Old cities & polder: canal system
Issues piped system:
- Limited lifetime
- Maintenance needed
- No retention: volume unused
- Expensive to enlarge capacity
- 'Puzzle' to implement with crossings
The Solution to All
HYDROROCK

Hydrorock
is:
- 100% natural product & environment-friendly
- 95% retention capacity
- Extreme long lifetime
- Fast and simple installation
- No impact on available space
- Can be placed under roads, parcs, sportfields, etc.
- Easy to enlarge capacity
- No maintenance
- 3 in 1: Retain/Store - Infiltrate - Drain
Possibilities:
1
Retention
Retain water
- under grass
- under terrace
- under parking
- under roads
No maintenance
2
Storage
- Large storage under parcs,
parking lots, pavements, etc.
- Very easy to apply
-
No maintenance
3
Discharge
Always a combination of
retention, infiltration & discharge
1) Hydrorock fills till saturated
2) Immediately infiltrates
3) When saturated, functions as pipe
4) Holds water under incline
-Standard densities: 75 kg/m3 and 120 kg/m3
-Storage Capacity: 95% 92%
-Load bearing: 2000 kg/m2 4000kg/m2
-Release response minutes hours
-Holds water under gravity - releases under suction
-Allows for root growth

car
simple point load calc:
30 cm ground coverage
Hydrorock max Load 2000 kg/m2
60 x 60 cm = 0,36 m2 --> 720 kg
4 wheels --> 2800 kg car
Hydrorock
- 3-in-1 (store, infiltrate, drain)
- 95% volume retention
- extreme long lifetime
- easy to install
- no maintenance
- load bearing proof
- gravity proof

The Game Changer in IWRM
Rencana
- Masalah: Banjir di RS Awal Bros
- Solusi: waduk besar bawah tanah
- Bagaimana: Hydrorock di



- Impak: banyak kurang banjir
bawah tempat parkir
situs lain dekat RS (strategis)
sehubungan dengan akuifer
Perencanaan
Assess Hydrology
Assess Soil Parameters

Minggu: 11-15
Ongkos: 15 Milliar IDR
Pemodol: APBN 100%
Lokasi
Solusi 1: 2500m3 bawah parking
Solusi 2: 2000m3 bawah jalan

Design Issues
1) Get the water to the blocks!!!
2) Prohibit solids to get in
- non-piped system
- gravel
- pebbles
- grate
- permeable surface
3) Infiltration increases with 'snake'
