You may or may not know that Ireland has only recently started to charge for domestic water use. There has been some heated debate, but here are some simple numbers based my own household.
With two simple water butts – small 100l capacity costing about €60 In total (see the photo above) – I have saved at least 6,000 litres of water in the past year. At the metered rates this is not a lot saved financially, about €22. But if half of Irish households did this (about 600,000 houses) that is a total of €13.32 million per annum across the country. Not to mention how I have seen my kids get instilled with the idea of conserving water.
Of course that’s only half the story. Saving water from rainfall means less produced water, less stress on infrastructure, less energy consumed and so on. I have no idea what these effects would do to my savings figure above – certainly a multiplier.
Typical accountant you may be thinking, but that’s it, we need to think not only about costs we pay for water, but other costs too.
