Best Paani recently installed bio-sand filtration system in Mangalchhen Barrack (Bhawani Dal) at Achham. Initially the barrack was suffering from severe water problem. Though water was sufficient it was not suitable to drink without treatment. All the people of the barrack had been consuming bacteria infested water and now after the installation of this system, all the users have access to clean drinking water. The system will now serve clean drinking water to all the 900 users of the barrack.
