If anyone needs an example of what Twitter or other forms of social media can do for their organisation? Ask Charity: water on February 13th after one hell of a party has taken place. worldwide

On 12 February 2009 100+ cities around the world will be hosting Twestivals which bring together Twitter communities for an evening of fun and to raise money and awareness for charity: water.

The Twestival is organized 100% by volunteers in cities around the world and 100% of the money raised from these events will go directly to support charity: water projects.

In September 2008, a group of Twitterers based in London UK decided to organise an event where the local Twitter community could socialize offline; meet the faces behind the avatars, enjoy some entertainment, have a few drinks and tie this in with a food drive and fundraising effort for a local homeless charity.

The bulk of the event was organized in under two weeks, via Twitter and utilized the talents and financial support of the local Twittersphere to make this happen.

Around the world similar stories started appearing of local Twitter communities coming together and taking action for a great cause. Twestival was born out of the idea that if cities were able to collaborate on an international scale, but working from a local level, it could have a spectacular impact.

By rallying together globally, under short timescales, for a single aim on the same day, the Twestival hopes to bring awareness to this global crisis.

charity: water is a non profit organization bringing clean, safe drinking water to people in developing nations by funding sustainable clean water solutions in areas of greatest need.

Right now 1.1 billion people on the planet don’t have access to safe, clean drinking water. That’s one in six of us.

Unsafe water and lack of basic sanitation cause 80% of all sickness and disease, and kill more people every year than all forms of violence, including war. Many communities in developing nations often have a plentiful supply of clean drinking water just below the ground, but no way to get to it.

The organisers behind this project are volunteers and have shown us all what can happen when you think big and put in a lot of hard work.  I’ll be attending the Manchester Twestival -hopefully see you there.
