<div>Hi,</div>
<div>I've been mapping on Africa in HOT tasks and around, I've
seen some cisterns, also know that some humanitarian NGOs have
made many cisterns on Africa (also water_wells).</div>
<div><span style="font-size: 12pt;"><br>

<div><span style="font-size: 12pt;">Question:</span></div>
<div><span style="font-size: 12pt;">How to tag a cistern (i</span><span

shown for "landuse=reservoir"; rather </span><span

ground level or escavated, for either natural or treated
water)?</span></div>

A 'cistern' has a mechanism for keeping a water level stable,
commonly used in toilets. And OSM has no tag for that feature
(yet). They are connected to a water supply with some pressure
behind it. <br>
<br>
I'd think you want to map the provision of water? <br>
If it is 'drinkable' then the generic amenity=drinking_water would
suit? <br>
If non potable then amenity=watering_place ? <br>
<br>
If you don't know if it is drinkable then assume not, so use </big><big>amenity=watering_place
? Maybe add a note ? <br>
