The swimming pool 

The pool size is 10m x 5m and is roughly 1.6m deep. Fed from the river, it was used purely as a holding tank for water for irrigating the land.

With no filtration or treatment, it wasn't surprising that the water was dank, green and not very inviting for a swim.

The six inch layer of foul-smelling sludge at the bottom had to be shovelled out. In the hot summer sun and with hundreds of flies attracted by the smell it wasn't the most pleasant of jobs!
When all was clean, the walls had to be scraped and painted.... 

...before the pool could finally be filled!

And here's the pool pump and sand filter that help to keep the water clear and sparkling. The next step will be to build a brick housing around it to keep it all weatherproof.
