In poorly managed systems, water pressure can be so low as to result only in a trickle of water or so high that it leads to damage to plumbing fixtures and waste of water.

If we impose a strict rule of sustainable utilization and limit the amount of extraction of water to that of the current water recharge, it would in reality deny aquifer States the right to utilize the valuable water resource, accumulated over the years, in the aquifer.
