The other day it rained for the first time in 9 days, and at the time, our harvested rainwater supplies were almost completely gone. The really bad news is – it’s only May and the long hot summer period that always follows the rainy season (June) is still quite a way away.
Summer dry spells over the last two years have become noticeably more frequent and watering the garden, more and more of a commitment. As a result, I have been planning various improvements to our water conservation measures. These are;
- adding more upcycled tanks to increase the capacity (by around 800 liters so far) of our rainwater harvesting
- collecting old hoses to make a drip-feed systems. For this holes are drilled into lengths of hose which are attached to junctions that help spread out and shorten the path the water has to take. Finally just shut off the end of the hoses with pieces of wire (see photos above)
- diverting the greywater from the washing machine to a soak area in the back garden and having the rest of the house’s greywater going into the wetland area around the pond (shown above). Although we use washing power which is phosphorus free etc and is designed not to harm the environment, in the past when too much gets through the wetland area and into the pond, it can still kill fish.
In addition to the dry spells we are experiencing, I also read an article which predicts a particular hot dry summer for North East Asia.
