High TDS in Water Clogging Pipes

Is there an efficient solution to overcome clogging due to high TDS?

One of our clients in Chennai has total dissolved solids TDS=1200 mg/l.

The desirable limit by World Health Organization ( WHO) is 500 mg/ l and the permissible level is 2000 mg/l. 

They are using the water for day to day use and their pipes get clogged within one or two years.
