Translation of Wasserspeicher

I want to work on the country specific terms first, then do a revision of the words that we have entered so far... please give me a few days to finish it. However, I may need to contact you over the weekend, depending on my progress.
This afternoon I will fly to Chile. My two brothers and sisters live there. They are also very old and my brother has already died. My parents emigrated 30 years ago, but they wanted to stay.
I'm glad as well, thanks for the suggestions. I had little time last week as we had many important meetings. I beg your pardon. Let us continue later. Many greetings from Germany.
