Learn About Chlorine

A collection of short e-learning tools and job aids to help water technicians treat, disinfect and safely handle drinking water under field conditions.

This collection contains the resources for both trainers and participants for the Rainwater Harvesting workshop. This four-five day workshop is designed for organizations and individuals interested in starting a rainwater harvesting program. The workshop offers instruction on the concept and technology of rainwater harvesting for domestic use and how it fits into the overall picture of appropriate rural and urban water supply in developing countries. Topics to be addressed include water supply and demand, selection of appropriate rainwater harvesting technology, and the basic construction, installation, operation and maintenance of roof top and surface catchments.

This poster set includes water, sanitation and hygiene (WASH) posters to teach about good WASH practices, including household water treatment technologies.

Water Safety Planning

This presentation is used to support the Maintaining Water Supply Schemes Lesson Plan (O&M Nepal). It addresses identifying maintenance issues with water supply schemes.

In this lesson, participants explore the factors that influence the successful operation of water supply schemes, activities required for effective operation, plan for common challenges, and examine how to cover costs related to operation and maintenance.

The focus of the lesson is to introduce water supply schemes, types of water supply schemes, and the parts of the scheme. Participants will also explore the role of user committees to operate and maintain water supply schemes sustainably.

The lesson plan focuses on the importance of WASH for community health, its link to the water supply scheme, and the role of the water supply user committee in advocating for better WASH practices. Participants will also understand disease transmission routes and the link between WASH practices.

This lesson focuses on the introduction of tools and fittings for operation and maintenance activities of water supply schemes. It allows participants hands-on practice to make or adapt locally available HDP fittings and thread cutting of GI pipe.

This presentation is used to support the Sustainability Planning Lesson Plan (O&M Nepal). It addresses planning for the sustainability of water supply schemes.

In this lesson, participants will practice re-focusing operation and maintenance problems into positive and achievable objectives. In groups, they will explore these different objectives and create strategies for how to achieve them.

This participant list template is a tool that will help you keep a database of participant information for your Operation & Maintenance of Water Supply Schemes in the context of Nepal workshop.

In this lesson, participants learn about different types of maintenance and explore the activities necessary to maintain water supply schemes over time. Participants will also create a plan for maintenance activities.

In this lesson participants will discuss where fresh water comes from, its scarcity, and how to protect it.

This session will look at how governments, civil society organizations, donors, and other stakeholders can maximize the impact of water point mapping. From planning water point mapping activities, to sharing the data, to analyzing the information and taking action, this session will look at best practices, opportunities, and future trends. Participants will get to learn about the state of the art in increasing the value of water point data through a presentation by the Water Point Data Exchange, and then have an opportunity to participate in a virtual discussion on next steps.

Ecofiltro is a social enterprise that set a goal in 2010 of reaching 1 million families in rural Guatemala with a clean water solution by the year 2020. A cross subsidy strategy was setup whereby urban filters were used to subsidize rural sales. From the beginning, the rural poor were viewed as potential customers as opposed to objects of pity. A low price point was set to make the water filters very attractive by having a 3 month or less payback. The strategy started with a focus on community entrepreneurs as primary sales agents and has evolved to making schools in the countryside the main channel to selling filters to parents of school children. Financing models were setup and tweaked and today Ecofiltro has reached over 250,000 paying customers in rural Guatemala. The model is now being exported to Mexico and the rest of Central America.

The public health consequences of chemical exposure are now comparable to or greater than those of widespread infectious diseases such as HIV/AIDS, tuberculosis, and malaria. However, despite large human and economic costs, chemical pollution of the environment and water sources has been overlooked in the WASH development agenda. Chemical pollution control currently receives less than 0.5% of global development spending. Biomass char (biochar) has shown promise as a low-cost adsorbent for uptake of SOCs from drinking water that can be generated using local resources in developing communities.

On the Pacific Islands, fresh water is scarce. Rainwater is a main water source of drinking water and other critical needs. This session will address how reliable, sustainable supplies of quality, drinkable rainwater can be achieved in an economically feasible fashion.
