A reading above 1,000 ppm puts your supply at twice the BIS acceptable limit of 500 ppm and firmly into borewell territory. It is drinkable in the sense that it will not make you ill this week, but it tastes brackish, it scales everything it touches, and it is a genuinely demanding brief for a domestic purifier. This page is about specifying for it correctly rather than optimistically.
Start with the number you should actually design around, which is not the one you measured. Borewell and tanker TDS climbs through summer as the water table drops, routinely by 30-40%. If your meter reads 1,100 ppm in August, design for 1,500. That single adjustment is the difference between a membrane that lasts a year and one that fouls in five months.
Between 1,000 and 1,500 ppm, a standard 2,000 ppm-rated RO is the correct and economical answer — the KENT Grand Plus, Aquaguard Delight NXT and Pureit Copper+ all qualify, and all include the TDS controller you need. Above 1,500 ppm sustained, move to a 3,000 ppm membrane (the AO Smith Z9 is the main domestic option) or add antiscalant dosing ahead of a standard one. Do not try to save money by running a 2,000 ppm unit on 2,200 ppm water; you will simply buy membranes instead.
Two expectations worth setting now. Output will be around 80-130 ppm with the TDS controller set mid-range, which is exactly where you want it — chasing near-zero output on this input wastes far more water and tastes worse. And membrane life will be 10-12 months, not the 18-24 on the box. Budget for it rather than being surprised by it.
