NEW INDUSTRIAL LANDSCAPE AS A LIVING MACHINE

Wang Hanfeng

In Singapore, the 42% of coastline, which is occupied by the industrial area, is covered with man-made vertical seawall. In Sungei Pandan’s industrial area, there are lots of factories, including many seriously polluted shipyards. The contaminants flows into the sea with rainwater, causing a negative impact on the natural environment. The pollution analysis indicates that the factories along the Pandan River, which are shipyards and manufacturing industry, have the most serious pollution level. The project aims to propose a new prototype of industrial landscape that is beneficial for improving the ecological and environmental quality through biological purification system while serving recreational activities for the public.

Four strategies are used during the design process. Firstly, ensuring the space for water treatment plant by replacing the current factories in the site; secondly, establishing of water treatment process based on the principles of wetland ecology to purify the water sequentially from sedimentation pond to heavy metal treatment then pathogen treatment and nutrient treatment. The treated water will be used for plant nursery before flowing into the sea. Thirdly, increasing of public engagement by combining the water treatment process with education, enriching people’s space experience; fourthly, creating aquatic habitats by modifying the coastline and creating an inter-tidal zone for mangroves and other plants and animals.

The project envisions this new kind of prototype of the industrial landscape will be duplicated along the entire coastal industrial zone in a long-term plan to create an ecological coastline for purification, restoration and education.

Site Analysis

open spaCe anaLysis

Residential Area

Building: 107510m2

Area: 515064m2

Percentage: 20.9%

The residential area is mainly occupied by HDBs. The precentage of openness is about 79% , just the same as that in industrial area. However, the buildings in this area are smaller and more seperated. So, compared to the industrial area, the open space here is more evenly distributed, which means that it is more fragmented and hard to be used.

Industrial Area

Building: 137103m2

Area: 684350m2

Percentage: 20.1% indusTriaL anaLysis

This industrial area is mainly occupied by shipyards. The precentage of openness is about 80% and the buildings in this area are bigger but more concentrated. So it has a larger and more integrated open space for redeveloping.

Singapore is regarded as a distribution center. Entrepot trade as a single economic form occupied the dominant position of the Singapore economy.

Computer, computer accessories manufacturing and other electronics industry become the leading industry, developing high-tech, high-value precision industry.

The government introduced and developed life sciences and environmental protection industries, the water industry and educational industries.

Singapore government introduced a large number of foreign investment and the technology and promote the development of capital-intensive manufacturing.

Singapore established the manufacturing and the industrial structure that took capital and technology-intensive industry as the center of the structure.

Site Analysis Strategy I

The site is in the industrial area that is beside a canal and opposite the west coast park. Also, the site is located at the river mouth,. It is like the gate at the center of the cross.

Ensure the space for water treatment plant by replacing the current factories in the site.

Strategy I

The average rainfall(monsoon): 25.8mm/d

The whole site area: 1777908m2

The whole rainfall : 46164m3/d

The potential treated area: 173308m2

The potential treated rainfall: 4500m3/day

The site area: 34407m2

4500m3/day

The current building area: 7016m2

The current industrial type: shipyard

The new designed building area: 3000m2

The new designed industrial type: water industry

Strategy Ii

polluted clean

Water treatment process

Pathogen treatment

Area: 4000m2

The third stage to treat the water by mostly using emergent plants to remove the pathogen when water flows through their roots.

Surface Flow Constructed Wetland

Plant nursery

Area: 750m2 water from drainage aerating

The fifth stage is to use the treated water and it is also a comprehensive treatment.

Sedimentation pond

Area: 2000m2

The first stage to treat the water, letting the suspended solids settle down.

Nutrient treatment

Area: 1500m2

The forth stage to treat the water by using various types of plants to remove nitrogen and phosphorus from water.

Heavy metal treatment

Area: 2000m2

The second stage to treat the water by mostly using submergent plants to absorb the heavy metal in the water.

Establish a water treatment process based on the principles of wetland ecology to purify the water sequentially from sedimentation pond to heavy metal treatment then pathogen treatment and nutrient treatment.

Strategy Ii

Vertical Subsurface Flow Constructed Wetland

Strategy Iii

Increase public engagement by combining the water treatment process with education, enriching people’s space experience.

In this area, people can see the process of pathogen treatment and have a aerial view to see the coastline.

In plant nursery, people will find some kinds of herbs that has beautiful flowers or comfortable smell. It is like an ornamental garden. The water used in here is comes from the polluted water after purification. Also, it has indicated the water quality.

The area is a part of mangrove area. People in here can see different kinds of mangroves and they can learn the knowledge about how the mangrove grows, its growing habits and its functions.

Secondary road

Potential animal corridor

Interaction area

Here is the place for people to rest. People can lie on the grass and see the process of nutrient treatment and the flowing stream, even small animals. This area is also a inter-tidal area but it is more for other aquatic plants and animals. People can observe and even touch the plants or the small animals in the water. It is a good place for people to experience.

Strategy Iii Strategy Iv

Create aquatic habitats by modifying the coastline and creating a inter-tidal zone for mangroves and other plants and animals.
