. Perhaps state of the art water treatment is not appropriate on reserves with only a few hundred people and with the required ongoing technical support for high tech systems hundreds of miles away from the reserve.. A lot of us use reverse osmosis units in our kitchens for drinking water...Kelowna and Phoenix ( to mention just two cities) use RO for drinking water without large $costs in capital investment or maintenance. All one has to do is change out the three filters once a year at a cost of $20 per household. Using high tech/high cost membrane filtratration for water to fight fires could also be questioned ....most small communities use pumper trucks to fight fires. I also wonder why the curbside water valve was left turned on to the vacant house that leaked three truckloads of water.
