TDS for potable water

TDS is actually an aesthetic quality of water hence does not have a health guideline value or permissible limit as such. There are no health effects directly attributable to TDS. Being an aesthetic issue, it depends on peoples views but generally good palatability in drinking water should not exceed 600 mg/L. Some people can even tolerate water with TDS of 600-900. 

But also take into consideration that high levels of TDS may cause excessive scaling in pipes, boiling apparatus (heaters etc), so will be bad for the retic system and objectionable to consumers.
