Procter & Gamble next week will launch a social media campaign. This one, it hopes, will make a big difference. The effort aims to martial the power of bloggers and social network users everywhere to raise awareness for the need to bring clean water to children in need. The do-gooder campaign hopes to distribute roughly 200,000 liters of water with the help of your clicks.

The effort, called “Give Health Clean Water Blogivation,” is part of a larger P&G CSR commitment in which the company provides clean water, vaccines and education to children in need. As part of the Blogivation campaign, P&G will release on Nov. 1 a widget that bloggers can post as a badge to their site. (We’ve requested ours). Every click on the widget will correspond to a day’s drinking water to be given away by P&G. As Mashable reports, P&G has enlisted the help of bloggers from the Blogher network. These writers, or “Changents” as they are being called, will be documenting their travels and efforts through the Give Health homepage.

The Blogivation comes just a few weeks after the highly successful Blog Action Day 2010, held on October 15. For that event, more than 5,700 bloggers from 143 countries participated in an online movement meant to raise global awareness for the most pressing issues facing the world’s freshwater supplies, from water scarcity in Africa to the need for all of us to pitch in for river conservation. Sponsors included Google, Treehugger, Grist, Change.org and many more to illuminate these issues to an estimated readership of more than 40 million.
