How much does a biosand filter cost?

Have you figured out how much it will cost you to implement your biosand filter project? Have you considered the cost of the technology and the cost of providing training and follow-up support for users? 

Here is our Biosand Filter Costing Spreadsheet that walks you through everything you'll need to consider to budget for construction, transportation, and user support. This is a great tool to use when working on a funding proposal for a filter program, or planning how you'll use existing resources.

Also, head over to this page for some funding opportunities that you might qualify for!
