Rainwater Harvesting

After a period of about a month without much rain our 1,000 gallon rainwater harvesting tank was getting low.  

It started raining yesterday about 1pm and it rained on and off until 3am this morning, recorded accurately by our weather station.  In that time just 13.5mm  of rain fell but the water level in the rainwater harvesting tank rose from 28% to 52%.

All of the rain that falls on the tower roof, the annex roof and now on the navvy hut roof goes into the harvesting tank.   That is  very large catchment area - and the system works!
