Dear Mrs. Bhatnagar, The solution for this situation is to separate completely salt from water, a process usually named as Zero Liquid Discharge (ZLD), and it simply consists out of 2 steps: 1- Evaporation (separation) of water , 2- Crystallization of salt. We are presenting this ZLD while referring to Room Temperature Evaporation rather than Reverse Osmosis (naturalseawaterdesalination.com).
Despite you are speaking about a small limited situation, however your problem is now a global emergency.
Reverse Osmosis is an inappropriate process, unhappily it is baked by an industry which is persisting for survival, dragging the worldwide community into a dramatic environmental problem. You are speaking about "few cubic meters", however now the Mediterranean sea, Red sea, and Arabian (Persian) Gulf salinity is increasing to the level that all reverse osmosis plants in this region will face the results of total inability to generate potable water any more.

Before you bash a very powerful, effective and highly useful technology, why don't you suggest what is an "appropriate technology". Water management is really a matter of managing the best out of the available resource, and acting with appropriate stewardship in the disposal of the by-product.
