I had mentioned about the subject/project sometime ago. Now the pictures are ready and thought it might be wise to share here.
The collection pipe is fitted to the roof of our kitchen. It was a 6" pipe, cut laterally to make two lengths. Have used cheap methods to divert the water into the barrel. I have used a plastic bottle by cutting the side to fit to the collection trough and into the barrel. The overflow will slowly pass into the smaller barrel. I have used a 1 gallon PET bottle for the filter by cutting its base and putting its nozzle into the opening of the barrel. Have used 4 layers of sponge to keep out smaller dirt. The leaves and other bigger particles fall into the kitchen filter kept at the entry point. Cleaning the filters is very easy. It is working very successfully.
