There's also a need for signalling and alarm/loudspeaker for people if they open the emergency door without authorization (Jasper asked for this). This can be handled on the same Raspberry Pi, hence some of the cost/effort can be shared between both projects/needs.

Variant B: build a 10-15 mm rim from cement/sand mixture onto the platform inside the emergency door (top of the metal stairs), with a pipe embedded in it on one side, that prevents the water from flowing down the metal stairs and instead leads it into the pipe, which flows passively into a water container below the metal stairs. The kind of big water tank that Michael Trew bought for aquaponics costs around £20.

In all cases, we use one Raspberry Pi computer which is connected over ethernet. Processing will all be done on the Pi, i.e. no servers will be needed. The Pi will measure water levels both in the basement and in the area outside the emergency exit and in Variant B inside, as well as in both water tanks. It will turn on the pumps as needed, and issue alarms over email/SMS/IRC if the situation requires it. There will be a web interface to see the status, silence alarms, modify sensitivity values, and access stored measurement data (for observational/statistic purposes to see how often back flow happens and how high)
