Summary

This manual focuses on water disinfection and the installation of raised hand pumps. It introduces the concept of "high-call," elevated water sources commonly found in hilly areas. These high calls are crucial for communities due to their strategic positioning and accessibility. Construction considerations for high-calls include geographic location and required materials. Ensuring the purification of water from sources like high-calls and tube wells is essential, involving specific materials and methods to ensure safety for consumption. Proper purification timing and location maintenance are crucial for maintaining water quality. Overall, utilizing high calls for drinking water, combined with thorough purification practices, can alleviate the need for villagers to travel long distances in search of safe drinking water.
