The World Toilet Expo is coming to Singapore this December.  As they point out:

There are an estimated 2.5 billion people who remain without proper sanitation facilities worldwide.

This translates to an unprecedented demand for over 500 million new household sanitation systems, as well as sanitation facilities in schools, religious buildings, marketplaces, transport centres and places of recreation.

Members of the global community need to openly discuss pertinent issues, implement new policies and achieve measurable targets. United Nations agencies, regional and international organisations, civil society groups and other relevant stakeholders from all countries, have important and functional roles to play in relieving the world of this silent humanitarian crisis.

The conference will cover such things as

Creating demand at the bottom-of-the-pyramid (BOP) market
Designing, engineering and manufacturing of sanitation solutions
Training and capacity development to ensure sustainability
Scaling up of sustainable sanitation solutions through social financing mechanisms
