High TDS in itself will not clog pipes.
However, if the high TDS water has a high pH, then depending on the constituency of the salts, some may precipitate out and attach to the inside of the pipe.
One way to counter this is to raise the pH of the water continuously with an acid injection and that's costly!
Another less effective method is to dose the pipe with hydrochloric acid solution overnight and "pig" the pipe next day, then flush. This is not totally effective, and needs to be done regularly.
Neither option is pleasant!
I know of a golf course which uses recycled water with high TDS and high pH. Its got to the point of abandoning the irrigation system as its totally blocked from salt deposits. The cost to acid inject continuously is too high. Total disaster.
