LOVE the water tank. When I was a little tacker. I was the nominated body to go into the drained tank to clean it out.. Just before the rainy season. Dead slimy frogs..usually a blob of fuzzy goo and the coating of "fur" on the walls and floor. The tanks were cement lined and only cleaned with a broom by a ten year old. Me. The tank was then flushed and ready for the rain, off the roof. I can't see anyone climbing inside a tank nowadays to clean it. And what washes off the roof nowadays is a little disturbing. We drank that water and never got sick. It was truly clean...tested on mums insistence.
These surburban tanks should only be used to water the plants. Not the veges ! ha ha
