Samenvatting (Dutch description)

Pateros river, Manila

With global warming promising more frequent and heavier rainfall, town officials are afraid that the river will overflow and submerge Pateros in dirty water.

The waterway has become an �unflushed toilet� used by two million residents. Therefore it has also become a source of diseases like dengue fever and meningococcimea. The IWASTO Project aims to clean-up, rehabilitate and preserve the Pateros River as it contributes to the following:

Flood prevention Disease control Urban development

Abstract: Climate change and urbanization will increase the frequency and magnitude of urban flooding and water quality problems in many regions of the world. In coastal and delta areas like The Netherlands and the Philippines, where urbanization is often high, there has been an increase in the adoption of sustainable urban drainage systems (SUDS). SUDS are installed around the world with the expectation to reduce urban flooding and reduce the pollution impact on receiving waters. Most cities in Asia are starting to implement SUDS as their strategy to make their cities sustainable and resilient. The combination of SUDS with appropriate wastewater treatment and management systems have the potential to be multifunctional in alleviating flood run-off, improving water quality, alleviating heat stress and as a source for reusing the stormwater and wastewater. Since the earliest SUDS are implemented in Europe decades ago it is advised to use the lessons learnt in this process. International knowledge exchange is promoted in projects as IWASTO where several organisations from the Philippines and The Netherlands join forces on a specific region as the Pateros river in Manila with the aim to minimise the pollution impact on this receiving water. The first findings of this project related to storm water and wastewater management are presented in this paper. In this stage of the project high level support models that map the challenges in the city (such as flooding and heatstress) are valuable tools for implementing cost effective sustainable drainage for improving water quality.
