How to clean narrow-opening storage containers, like the jerrycans?

@Brian Reed made a great observation during the webinar about a student project (unpublished) on removing algae from plastic containers. 

From the existing literature, when conducted properly, the method of cleaning plastic containers using sand seems to be effective, but it may lead to premature aging of the container.

Check the following resources and studies for more details on this topic.

  2.  Keeping water from kiosks clean: Strategies for reducing recontamination during transport and storage in Eastern Uganda Gärtner et al. (2021)
  3. Efficacy of locally-available cleaning methods and household chlorination at inhibiting biofilm development in jerricans used to store household drinking water  String et al. (2020). Download the author version here

NEW LIVE WEBINAR: A water professional’s guide to safe storage

Testing and treatment is only part of the equation to achieve safe drinking water at the point of use. How do you select a container for storing water once it’s been through sedimentation, filtration and disinfection? How do you keep it clean and prevent contamination?

To answer these questions and more, the HWTS Network is hosting a live webinar featuring experts from Eawag, the Swiss Federal Institute of Aquatic Science and Technology, and the Centre for Affordable Water and Sanitation Technology (CAWST). Join us to get helpful resources and job aids on safe storage, and stay for a Q&A.
