Just sink 'community boreholes'  - a few per suburb. Make it clear that it is not for drinking purposes and if you do you should treat it or boil it first. Provide water treatment pills.
We can turn it into a community chat around The Pump kinda thing - better than armies and police.
Run a campaign that warns and educates about symptoms of water born diseases especially Cholera and Typhoid (just in case!).  You could even fit the nozzle wit a filter system to get rid of sediments.
You can even retro fit the pumps to crank handles so you tackle obesity too, It will also stop everyone from saying how unsightly the pump is and the endearing 'quaint' will be used. It also negates the need for noisy pumps.
