low level water detector with solar cell as batery source

I need low level water detector which will use solar power. Alarm should be some long audio beep that I can hear on 100 - 200 meters distance and it should repeat like alarm on mobile phone, until I turn it of manually. Another solution for alarm can be some remote action (turning on some light in the house or something. Any idea is ok.

Device should be delivered in Serbia, Europe
