Water that's pumped from its source, filtered and treated for hardness and for high acidity to lower the risk of lead, removed of suspended material and sediment, then micro-filtered, disinfected and tested? Or would you want your drinking water to be cleaned by someone armed with a simple sieve, the kind you use in the kitchen to separate the lumps from the gravy before dinner?
