Laem Phak Bia Environmental Study and Development Project

The project was a Royal initiation by His Majesty King Bhumibol Adulyadej (Rama IX) to conduct research on finding suitable technology to solve waste and wastewater problems under the ‘Nature Heals Nature’ principle.

During their visit to this project, travelers will have an opportunity to learn how polluted water can be transformed into clean water with natural methods before being released into the sea in order to prevent the coastal environment from being destroyed. More importantly, they will learn the benefits of natural processes that have been applied to successfully solve various problems. The wastewater treatment, for example, is divided into four systems. The first system is the wastewater treatment tank that features algae photosynthesis to supply oxygen for microorganisms to breathe and digest organic matters in the wastewater. The second system utilizes a plant and grass filtration system by planting ThupRue Si (Bulrush), Kok Klom (Papyrus Sedges) and Ya Faek Indonesia (Indonesian Vetiver) to help filter and absorb contaminants in the water. The third is an artificially constructed wetland system that simulates a natural setting. When wastewater is released into the tank that grows sedge plants, their roots help absorb the toxic substances. The final system on display is a mangrove forest filtration system that dilutes wastewater using sea water. Also, Bulrush used in the third system will be cut and gathered after 90 days and passed to a housewife group to weave into various types of products and generate income for the community.

This project has created sustainability for all parties involved, solved numerous environmental problems and generated much needed income.     An additional benefit is that visitors can harvest knowledge for future adaptation, learn the values and methods of nature that can be applied toproblem solving in general and realize how all man-made pollution can ultimately create problems for the world and for ourselves if is not dealt with. In the mangrove forest, visitors can admire various plant species including Avicennia and Rhizophora, spot marine animals in their natural habitat and even hear the snapping sound of the bizarre Snapping Shrimps as they proper themselves around under the mud. It is also a highly recommended bird-watching spot with numerous rare bird species. Visitors can also witness the actual Phak Bia Tha Le (Sea Purslane) itself, which Laem Phak Bia (Phak Bia Cape) was named after, in the outer mangrove forest area.
