<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 />
</span></div>
<div><span style="font-size: 12pt;">Question:</span></div>
<div><span style="font-size: 12pt;">How to tag a cistern (i</span><span style="font-size: 12pt;">t seems to be not like what is
shown for "landuse=reservoir"; rather </span><span style="font-size: 12pt;">a small "man made" reservoir, on
ground level or escavated, for either natural or treated
water)?</span></div>
<div><br />
</div>
<div><span style="font-size: 12pt;">Or, in addition, s</span><span style="font-size: 12pt;">ince there are tags for </span><span style="font-size: 12pt;">"man_made=water_well, </span><span style="font-size: 12pt;">"man_made=</span><span style="font-size: 12pt;">water_tower</span><span style="font-size: 12pt;">"</span><span style="font-size:
12pt;">, w</span><span style="font-size: 12pt;">ouldn't it
be worth to have a tag like </span><span style="font-size:
12pt;">"man_made=cistern"? </span></div>
<div><span style="font-size: 12pt;"><br />
</span></div>
<div><span style="font-size: 12pt;">Thank you in advance,

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 />
<br />

In American usage, a cistern is a holding tank for captured rain water, used as an alternative to a well in areas where no city water supply is available. They often take the form of an underground pit with a waterproof lining.<br>
