Goal of this task

Let's design and build an automated irrigation and rainwater harvesting system.

Don’t use too much time on one topic in the first go. Go through all the parts and start over if you have more time. Let's try to keep an agile approach.

Content

For irrigation in Auroora we should use water from a combination of well, rainwater harvesting and local water supply. There are various ways to implement this and this document explains how and in what steps a system in Auroora will be built.

We also have to take into account that the system (or at least parts of it) has to be removed in the preparation for the winter and rebuilt every spring.

The main building is about two meters higher than the garden so valves between containers are needed, but probably not pumps. 

Rainwater harvesting

Containers

Automation

Central computer

Possibly Home assistant. We should be able to connect to it outside of Auroora over the internet.

Electrical switches

Valves

Pumps

Well

Submersive pump is typically used in wells. A cheap one will probably do https://www.k-rauta.fi/tuote/uppopumppu-opal-400w-q400-b3m/6413820890203

Maybe the easiest way to use it is to start it when water level in a container is low.
