Water tank

– Max Netto capacity 175 m³
– Size: 20 m Long x 5 m Wide x 2 m high
– When measuring water level through access whole, when water level reaches 9 cm height, the water tank is “EMPTY”
  – reason is the tank has a slope of 10 cm over 20 m length of tank. At the end of the slope, the water pipe is mounted on 20 cm height.
  – this means the last 15 m³ water will never be used (is used to gather sediments from water so we don’t drink it)
– Height of overflow pipes at the top of the tank is 175 cm above the water pipe which transports the water to the building. Hence max 175 m³ netto capacity.
– Both overflow pipes have been protected for animals in August 2017.
  – Reason is we found some little dead animals in the water tank which we think can get into the tank through the overflow pipe, but can’t get out anymore.
  – Done with aluminium mesh with metal kitchen scrubbing wool inside
– The water tank was completely cleaned inside with a high water pressure on the side walls, ceiling and floor. Date August 2017.
– There was a difficulty cleaning the tank since the water pipe that is actually at the complete bottom of the tank, which is meant to empty the tank for cleaning
  – was completely blocked with roots and other stuff

Actions to be done every year:
– Before the camps or at the beginning (when we still have high water level): open the lower water pipe exit for a very short moment
  – to remove any dirt in it so it doesn’t have the chance to start blocking the pipe.
  – this pipe ends in the same metal box where the main water supply can be opened or closed (outside of back dorm)
– Check the water level of the tank every few days with a measuring stick and keep an eye on the water consumption.
  – If we start with a full tank and there are 2 camps only 5 m³ per day can be consumed (5 cm of water level difference)
  – note: a little more is allowed IF new water comes in (this was NOT the case in 2017, it was in 2015 and 2016)
  – In 2017 at the end of the boys camp with 100 persons present, when everyone was using the least amount of water possible, still around 5 m³ water per day was consumed.
– If no water comes in, you can follow the pipe to the source. There are about 2 taps on the way which can divert water to fields from Daglio people
  – and also at the source itself water can be closed off to come to the Ananda Mela building (Lavaggio for the villagers)
  – All these taps should be opened so if there is water, it can come to our water tank while we have the camp. You can also close of the water going elsewhere.

Ideas for next year:
– Make one or several big information panels to inform children and adults not to waste water:
– don’t keep the tap running while brushing teeth or washing hands. Take water to wet your hands, stop the water, use soap to wash them, then rinse while shortly opening the tap.
– disconnect flushes or even better, make sure they contain only 3 liters of water instead something like 6
– severely limit collective foot-soaks (individual ones are ok) (unless we have a rainwater tank, then collective foot-soaks can be done with that)
– save water taking a shower, only keep the water running for very short time frames.
– Properly document detailed water level at beginning of every camp + every 2 days, including pre-camp
  – on paper on the wall in the office for example.
– propose these water saving actions as permanent requirement in Daglio to prevent the situation of this year (possibly less attention to water due to plenty of water in previous years)
– Install a big rain water collector with pump so toilets can be connected to it. Also foot soak water can come from rain water.
– Install a water preassure device (manometer) in the kitchen which can possible show the level of water in the tank without having to go there physically)
  – might not be as precise as we need it, but might be good enough for a general idea
