In the Marshall Islands many people store rain water in large plastic tanks such as the one shown here in the photograph. Since there are too many people (some 20,000) in Majuro City, the capital, the underground aquifers are not sufficient enough to supply the entire population. Thus, plastic catchments are required.
The reason for my having entered this catchment: while assembling a makeshift table from beach logs I dropped a large piece of wood on the pipe leading out of the catchment, breaking the glue bond which was sealing the connecting pipes.
A cork from a wine bottle had to be shaved to fit the inside of the catchment pipe so that no water leaked out when the connecting pipes were fixed on the outside.
