Strawbale roundhouse & rainwater harvesting

Meeting a  need for food storage and a rainwater harvesting system

Some Words About This Project

Roundhouse rainwater store

Having a reliable water supply has been a priority for some time.  Our existing shallow well fills with water that has a high iron content, and which is not great to drink, even when filtered. We do have a mains supply, but have no control over the chemical content, and it is metered. Also it could be vulnerable in the event of a more widespread power failure.

We do have an abundance of roof area however, and so rainwater harvesting would provide an ample supply.

Notes – survey – where to put the store, how big to make the store. Commercial systems seem to be in the order of 3000 – 10,000 litres and tanks are expensive. Examine water consumption to predict necessary storage.
Available resources? – IBC tanks, 22mm water pipe,

Location – lower than the house.

Use – to irrigate the polytunnels. Drinking.

Considerations – distribution – not enough head for gravity feed – 0.1 bar / metre height, total fall is max 3m.

Their 'hobbit house' was the thing that got me started on my journey over a decade ago, and I was fortunate enough to meet and work with this amazing couple at Lammas Eco village in Pembrokeshire.

Builders and permaculture designers,

Suzie has taught me a great deal, not only through the PDC that I completed at Dulra, but through following her journey as she set up and established Carraig Dulra Permaculture Farm.

Charles' no nonsense approach to no dig growing has transformed the way I look at producing food, and his deep understanding of permaculture has been an inspiration. He was also kind enough to support our crowdfunding back in 2013.
