Instructions for use
This tank is ideal for sedimentation and/or flocculation. Water should ideally be transferred into another tank before chlorination, and distribution.
The tank should be installed on an even, stable and horizontal earth platform.
In an area with a lot of wind, it will be necessary to secure the tank against movement during storms. Tie a few ropes from the poles to pegs in the ground.
When installing on top of an earth embankment, ensure stability with a low gradient and a dense grass or stone cover on embankment slopes.
MSF requirements
Large storage capacity installation for refugee camps.
Low cost, low weight and small packed volume are appropriate for a fast deployment within the unstable context of complex emergencies.
Life duration: minimum 5 years.
