I believe that constructed wetlands (a type of phytoremediation - defined as the use of plants to clean up soil and water) will become more widespread in the near future. As society becomes more environmentally conscious (what with the issues of climate change being publicised almost non-stop nowadays), people are starting to look for sustainable and environmentally friendly methods of treating wastewater. Even though constructed wetlands have their limitations (e.g. a need for land), their natural appeal and sustainable character are hard to beat. And if you are business minded, this is one natural technology that should not be overlooked as its market (especially in developing Asia) is set to grow. I will be writing more about this in future posts.
Lorong Halus Wetland was transformed from a landfill into an educational site and biodiversity haven for plants, birds and other wildlife. Using an innovative bio-remediation system, national water agency PUB designed the Lorong Halus Wetland to collect and treat water passing through the former landfill, preventing it from flowing into Serangoon Reservoir.
At the same time, the wetland creates a new haven for biodiversity that provides opportunities for recreation, research, and education.
From 1970 to 1999, Lorong Halus was a dumping ground for Singapore's waste. It occupied 234 hectares (that's more than 100 football fields) along the eastern bank of then Sungei Serangoon.
Deputy Prime Minister Teo Chee Hean officially opened the Lorong Halus Wetland and part of the Punggol Promenade on Saturday, 5 march 2012.
Many People Think it is a waste of land space and Singapore and can Build Housing estate but there is a reason behind it.Using an innovative bio-remediation system, the PUB has designed the Lorong Halus Wetland to collect and treat water passing through the former landfill, preventing it from flowing into Serangoon River. The various reed and ponds traps and filter the 'dirty' stuff and prevent them from floating into the river which has become a reservoir.This Will Prevent Pollution in Great Amounts.
The Lorong Halus Wetland will provide a new space for members of the public to enjoy not just the tranquility and greenery of the wetland, but also the new habitat that this wetland has created for birds, butterflies, dragonflies and other wildlife. A rustic trail has been laid out among the reed beds and the ponds, allowing the public to get up close to the wetland system. A pedestrian bridge has also been constructed across Serangoon Reservoir to allow for easy access by the public and residents from the Punggol New Town located on the western bank of the reservoir. PUB hopes members of the community will take ownership of our waterways and waterbodies and play their part in helping to bring these places to life and keep the waters.
