We normally get an ample suppky of water at our house about three times a week. That is interrupted if there have been heavy rains and CORAPLAATA's filters are plugged up with silt.
The opposite problem occurs, as it is right now, with too little rain. We got water once in two weeks, but only after we spoke to CORAPLAATA who had opened the key earlier in the day but turned it off before the water got to us. As you know it's a gravity feed from the cistern under the old Sales Office. It still took two truck loads to get us back in action. Yes there is a scarcity right now.
Your water table may have shifted, as they will, since I haven't heard of other well owners with the same problem.
