Development of Community Based Arsenic and Iron Removal Unit for Rural Water Supply System

The research focused on development of a community based Arsenic-Iron Removal Unit (AIRU) adopting the technique of adsorption and co-precipitation of arsenic onto the flocs of ferric hydroxide, making use of the naturally occurring iron of groundwater. The operation and maintenance of the developed AIRU are simpler and more users friendly in comparison to the previously developed community based water treatment units. Number of beneficiaries and water consumption was increased by about 10 folds after the installation of the AIRU.

Sanitation Strategies and Technologies Flood-prone and High Water Table Areas of Bangladesh

Overflowing of latrine during monsoon flood and heavy rainfall is a common scenario in Bangladesh. To overcome this common problem, an attempt was made to provide technological solutions for safe sanitary latrines based on the concept of ‘raised latrine’ constructed above flood level in flood-prone and high water table areas. The technologies include ‘Earth Stabilized Raised Pit Latrine’, ‘Step Latrine’, ‘Mount Latrine’ and ‘Sand Enveloped Pit Latrine’.
