Level of detail: Foundation within an RPA

[Gary Prentice]

There's no reason not to have a butt, apart from planning/TO could justifiably point out that it would be reliant on the householder actually activating it, instead of watering the tomatoes. My approach would be to adapt 'my system' with rows of pipes across the width, not just along the outer walls. This system, as is, will put a lot of water in the rain shadow area of the exterior wall, which doesn't do much for soil moisture levels distance from it.

 

 

The collection area (roof) will be similar in square metreage to the voided area, so over-watering shouldn't be an issue. Localised over-watering if levels aren't correct would be an issue- like having a blocked gulley at the bottom of a downpipe where the surrounding soil gets excess and becomes waterlogged.

 

im sure with that there will be case studies online somewhere.
