HWTS Sanitary Inspection Forms

Hello everyone, 

CAWST and University of Surrey are working to develop Household Water Treatment Sanitary Inspection forms that can be used by community representatives, health workers, water inspectors and humanitarian professionals. Your feedback will help us to ensure that these forms reflect your needs and experience. 

Please review the draft sanitary inspection forms for boiling and household slow sand filters. Your review of each form should take approximately 15 minutes.

Let us know if you have any questions.

Take the biosand filter survey

CAWST needs your input! In 2023, the biosand filter celebrates a very important milestone - 30 years. We invite all biosand filter implementers and/or trainers to participate in a survey to measure the tremendous impact the technology has had – on the WASH sector, and in people’s lives around the world. The survey includes questions about your experience with implementation, distribution, and impact, and how you have applied new knowledge, skills, and innovations. 
All results will be anonymized, so your answers won’t be attributed to you in our reports. The survey should take between 5 and 10 minutes to complete, and it's currently available in English, Spanish, French and Nepali. Please add a comment if you would prefer to take the survey in another language.
Take the survey now
Thanks for your participation!

Installing a biosand filter is one of the most exciting parts of implementation! You get to see all your hard work come together and test your final product.

We have two videos to share with you on how to properly install biosand filters:
