Water Harvesting and Storage

Project: Petworth Balcony Garden

Posted by David Addis about 7 years ago

The developing system for catching and storing water on my Ground floor balcony. Ideas welcome!

Being on the  ground floor and directly below another balcony it's rare except with a mixture of heavy downpour and strong winds that rainwater falls onto my containers. When we first moved in and started growing, especially during the summer, we were using tap water and making repeated journeys from the kitchen, though our front room and onto the balcony.  It felt wasteful of both water, time and energy.

I have tried with leaving buckets/containers outside of my plot on the communal garden in front, however I am conscious of other tenants feeling that I am encroaching on communal space and the bucket is a bit of an eyesore in amongst the other plants.

Currently the newest system I have involves a drainpipe to catch rainwater (not connected to a roof), an innertube moving the water to a system of larger recycled water jugs, each of which connected by inner tubes which can be used as a hose.  The first container is roughly a metre of the  ground so produces enough pressure when full to water smaller plant growing containers.  I'll add a photo and diagram at some point as its easier to show than describe.

While I have solved the storage problem, the drainpipe has too small an area to catch sufficient rainwater. So...we are currently catching and storing the water from our shower.  Our shower takes a minute or two to warm up to a suitable temperature so we stand in the buff and watch a 3 or 4 litres of perfectly good (but very cold) water rush down the plug hole. While I could be brave and hop straight in, I have opted with having a bucket in the shower to catch this, and then transporting outside to the water storage.

At the moment, this is working but needs some fine tuning with pouring the bucket into the water storage.  But thats for another day.

Future Possible Water Developments (Id be keen for people to share their ideas on my future tasks)

Legend of Badges

Note: The various badges displayed in people profiles are largely honesty-based self-proclamations by the individuals themselves. There are reporting functions users can use if they know of blatant misrepresentation (for both people and projects). Legitimacy, competency and reputation for all people and projects can be evidenced and/or developed through their providing regular updates on permaculture work they’re involved in, before/after photographs, etc. A spirit of objective nurturing of both people and projects through knowledge/encouragement/inspiration/resource sharing is the aim of the Worldwide Permaculture Network.



A member is a permaculturist who has never taken a PDC course. These cannot become PDC teachers. Members may be novice or highly experienced permaculturists or anywhere in between. Watch their updates for evaluation.

Male memberFemale member

Permaculture Matchmaker

One of these badges will show if you select your gender and the "I'm single, looking for a permaculture partner" option in your profile.



People who claim to have taken a Permaculture Design Certificate (PDC) course somewhere in the world.


PDC Verified

People who have entered an email address for the teacher of their PDC course, and have had their PDC status verified by that teacher. Watch their updates for evaluation.



People who’ve taken a Permaculture Research Institute PDC somewhere in the world.


PDC Teacher

People who claim to teach some version of PDC somewhere in the world.


PRI Teacher

With the exception of the ‘Member’ who has never taken a PDC, all of the above can apply to become a PRI PDC Teacher. PRI PDC Teachers are those who the PRI recognise, through a vetting board, as determined and competent to teach the full 72-hour course as developed by Permaculture founder Bill Mollison – covering all the topics of The Designers’ Manual as well as possible (i.e. not cherry picking only aspects the teacher feels most interested or competent in). Such teachers also commit to focussing on the design science, and not including subjective spiritual/metaphysical elements. The reason these items are not included in the PDC curriculum is because they are “belief” based. Permaculture Design education concerns itself with teaching good design based on strategies and techniques which are scientifically provable.

PRI PDC Teachers may be given teaching and/or consultancy offerings as they become available as the network grows.


Aid Worker

The individual with this badge is indicating they are, have, or would like to be involved in permaculture aid work. As such, the individual may or may not have permaculture aid worker experience. Watch their updates for evaluation.



The individual with this badge is indicating they are, have, or would like to do paid permaculture design consultancy work. As such, the individual may or may not have permaculture consultancy experience. Watch their updates for evaluation.


Community Project

Community projects are projects that help develop sustainable community interaction and increase localised resiliency.
