The following water storage options can be used for temporary storage (bladder and onion tank), for constructing more permanent lined metal storage tank (tank kit) or for trucking water transportation.
When ordering bladder or other water storage systems, it is important to ensure that all necessary fitting for set up and operation are included. Number and fittings for all tapstands, piping, etc. need to be considered.
Water storage systems should only be ordered in consultation with WASH TA or other specialist in order to ensure appropriate size and type of storage, water quality at source and contamination-free transfer of water to distribution point.
