Predict one of these three classes based on a number of variables about what kind of pump is operating, when it was installed, and how it is managed. A smart understanding of which waterpoints will fail can improve maintenance operations and ensure that clean, potable water is available to communities across Tanzania.\n\nThis predictive modeling challenge comes from [DrivenData](https://www.drivendata.org/competitions/7/pump-it-up-data-mining-the-water-table/), an organization who helps non-profits by hosting data science competitions for social impact. The competition has open licensing: \"The data is available for use outside of DrivenData.\" We are reusing the data on Kaggle's InClass platform so we can run a weeklong challenge just for your Lambda School Data Science cohort.  \n\nThe data comes from the Taarifa waterpoints dashboard, which aggregates data from the Tanzania Ministry of Water. In their own words:\n\n<blockquote>Taarifa is an open source platform for the crowd sourced reporting and triaging of infrastructure related issues. Think of it as a bug tracker for the real world which helps to engage citizens with their local government. We are currently working on an Innovation Project in Tanzania, with various partners.</blockquote>\n\n![](http://drivendata.materials.s3.amazonaws.com/pumps/taarifadashboard.png)",
