Before suggesting a solution you need to know what is the composition of the TDS ("dissolved solids"). What is the composition of the pipe (PVC, metal, clay, et. al.)? If the pipes are clogged what is the material that is occluding the pipe walls restricting flow--has it been analyzed? Is it possible that this is a bio-slime and not a dissolved solid that is adhering to the walls due to polarity and plating out? As with any problem knowing the root causes can only be determined with additional analytical data as suggested in some of the answers below "guessing" at solutions.
