I have made a reed bed for treating bath,wash basin and washing machine water. The aim was to reuse the water for gardening without doing major changes in the plumbing of existing houses. I had posted a query in this regard on IWP and you can view that query/comment thread here : https://www.indiawaterportal.org/ask/12646
After close to two years from the first post here is an update:
1.The reed bed has excellent growth of Australian phragmitis and canna. The phragmitis took longer time to get itself established among the canna. However we trim the canna leaves every few months so that it allows the phragmitis to grow.
2.The dead leaves of canna and other leaves from neighbouring trees have deposited in the bed and created a good soil base. In these 2 years I have raked up the bed only once to ensure that no clogging is taking place.
3. Our garden to which the grey water is being fed is doing very well. There is no instance of leaf burning.
4. In the current dry season and heavy water cuts, it is a blessing to have this regular water source for our garden.
You can find some pictures of our garden and the reed bed here:
