Rainwater Harvesting ~ ‘If Only…’

Category: Barn Conversion Journal August 29th, 2008 by mbc

I’m not in the habit of giving advice (well at least not until recently), but the one regret that I have (well in addition to forgetting to put solar panels on the original plans) was that we didn’t go ahead and install rainwater harvesting.

I had a quote for a large tank and a variety of pumps, pipes and valves that came out at around £2000 including VAT. This was way back when we were drawing up plans and rainwater harvesting got lost amongst them and never became a firm inclusion. It was a £2000 that was easier not to spend at the time. Now, that two thousand will soon flow away through the water meter when greener more sustainable ‘free’ water could have been used instead. Additionally, the barn would have had a rainwater infrastructure that would have lasted for a lot longer.

There is a lesson here – I didn’t ensure that my original design and budgets allowed for all the technologically and economically sound options that I should have. I was blinkered by the basic needs of walls, floors, roof, windows and doors and therefore my initial plan lacked in detail … this lack of detail has a financial impact, both short-term (I had to apply for planning permission for my solar panels) and medium to long term (we will need to pay for water we wouldn’t have had to and any attempt to retro-fit rainwater harvesting will be messy and costly).

As always, the devil is in the detail.

Heating & Hot Water – a solution?
From the start of this project, I’ve been through numerous options regarding the method by which we’ll heat the barn and generate hot water for domestic purposes.

The Great Wall
Between the earth bank on which most of the garden sits and the barn lies a narrow strip of earth, perhaps 6 feet wide.

    Update May 2012:

    Actually there’s another lesson that has emerged over time… water bills are low at the barn and rainwater harvesting wouldn’t have replaced all mains water usage. I guess that £2000 would have taken 10+ years to pay itself off…

    So make sure you do all your homework when making design decisions…
