Statistics and analysis
In our school it is very difficult to know the exact amount of water that has been used to water the plants in our vegetable garden. Considering that, we analised how much it rained during the school year 2016-2017, and 2017 until February 2018.
We found the information in this website:
Climate-Data- org
https://es.climate-data.org/location/1564/
Rain amount from September 2016 until June 2017.
Total: 287 l/m2.
Rain amount from September 2017 until December 2017:
Total: 277 l/m2.
These are the conclusions after doing all the analysis:
· If we had used the rainwater during the last school year (2016-2017), the amount of water that we could have saved would be 287 litres.
· During the first three months of the current school year it rained much more, 277 litres, 10 litres less than the entire last year. If we had collected it, and if we add the amount we expect to collect this year, we could water our vegetable garden only with rainwater.
· Since we bought the rainwater diposits, we have collected:
January: 8'0 litres
February: 24'3 litres
Total: 32'3 litres
