Apartment has 24 flats. It currently has a water softener plant with hydraulic pumping system. The complex does not have overhead tanks. There is a proposal to do away with the existing softener and have an RO plant and construct 2 overhead water tanks of 4000 ltrs capacity for the two blocks, in the complex. It is a single unit complex. The waste water is to be connected to the sewage line. What is your opinion on this.
