What an elegant tank! And its curved wall-to-base joint that should reduce the peak stress at that point. The conical lid (lift-on?) adds to the appearance. This is necessarily a high tank. For low (i.e. 3/4 submerged) tanks the potential as 'garden furniture' or seating in the compound is even greater. A 30cm high square surround wall, with gravel or flowerbed infill and cement-tile capping, looks good, too.

Hi P,

Great calabash indeed.

Would that be a kind of mosquito net above the tank to sieve water. How large is the collection surface?

Please send some photos that can show how the water is harvested.

Kind regards,

Hi Elias,

Thank you for your reaction.

You do not need to filter rainwater, just cover the manhole with a piece of textile. The blue sheet is plastic, about 2x3m. Enough, because 2 meter rainfall in Guinea Bissau.

Much more information you find in the PDF Manual at the website (see right).

Kind regards,
