One of the easiest and efficient way of water conservation to solve drinking water scarcity is rooftop water harvesting. However, the technology has some limitations with regard to its purification system. The commonly used sand and gravel filter is very prone to clogging and its cleaning is not an easy job. At the same time, the alternative upward flow mesh filter needs further improvement in cleaning efficiency and some hassle free drain cum back washing mechanism. In upward flow mesh filter system, which creates anaerobic condition will give foul smell.

Soils of Bino-river watershed in Almora district of Uttarakhand, India in north western Himalayas were characterised and classified for land categorisation and perspective land use planning. On the basis of interpretation of remote sensing data and ground truth verification three broad landforms viz., ridge tops, side slopes and valleys were identified and further sub-divided into seven landform units based on slope gradients. Nine types of soils (Pedons 1 to 9) were identified in the watershed area.
