Right, the new diverted feed from the rain filteration system is now installed to the other corner of the rain tank. Hopefully we have avoided any leaks ! The old hole in the manhole access tube is blocked up with geotextile so no sand and soil can get in!

In the light of conversation about filtering the rain water and how small (or large) the particulates would get through the filtration system, we have decided to re-route the feed pipe from its first placement which is going into the manhole access chamber where the pump is situated which means it would immediately suck up […]

Then we humped the 87 aquacell modules down into the hole from their delivered location next to […]

Then installed 18 Aquacell modules in a 3m x 3m array, the modules were clipped together. A hole was made in to top to allow connection from the rainwater system. Finally the geo-texile […]
