Dear Dick Grimshaw
I found interesting information in the Vetiver Network Intl website.

How do you think Vetiver grass from your CWL will be used for income
generation ? Who will be the users ?

I have discussed the matter with my botanist friend and he will give me his views on location where vetiver grass can be found or else I shall have to get its seeds. May be Dick Grimshaw can give some tips. This I will use as one of the wetland plant out of 3-4 types that I have to plant there. I want to have more than one option by using may be two cells of CWL to get performance results with filling materials and plant types. This I hope to finalize at the end of this e-workshop.
Yesterday, I was at site after some time and find the arrangement of drainage stream not in the same condition and at locations even encroached upon and I do not think that we can have a parallel pond instead of CWL. Also it was found that some more housing units have come up along the stream and they too have grouped into small communities and are discharging their effluent into this very stream within a distance of 1Km. I missed to state earlier that this stream later joins after about a kilometre to a nallah which is a small river. I feel with this growing housing rate there has to be some treatment before disposal into this stream. I am sure once we have a successful CWL model for 10-15 houses initially, others will follow suit. The flow of the stream is around 1 cusec and that of small river is over 5 cusec at this time of the year. Do you have some other thought or alternative to deal with this scenario.
You have mentioned studies on die-off of micro organism process. I am not clear on this. You mean to say that micro organism reduces to half after 500 meters from the point where it joins the stream. By the way the typical result of untreated sewerage in Islamabad are reported to be BOD -300mg/L, total coliforms around 3.3 ×10 to the power 7.
Also I like to add that I mentioned 100 persons later and hence our target sewerage flow from housing scatter under consideration should be considered 22 cubic meters per day instead of 11 cubic meters. To your specific query on use of vetiver plant, please see my note for Dick Grmshaw below.
To Dick Grimshaw
You have shown one location in India and other in Madagascar with use of vetiver plants. Can you provide names of their exact location and relevant website if possible to study more details of these two specific locations. I feel Madagascar style use in irrigation canal is a relevant use as per scenario here. We can plant these vetivers there for treatment of sewerage water into the stream directly instead of providing CWL. Can you please give your comments on this.

My experience tells me to use local plants and seeds (and avoid
introducing new seeds and plants because it has been shown to work
well in another country and expecially in a different climate and soil
type.
Dick Grimshaw may wish to comment on this ??

by "cells" I presume you are thinking of "ponds".
Q: what size of ponds are you thinking of ?
Q: where do you intend to plant the Vetiver grass ?

You are right cells and pond has same meaning here. My rough working at the moment reveal that I need some thing like 3,000 square feet of pond for 100 persons domestic sewerage based on 1,000 square feet area for 2,000 gallons daily inflow. That means eight ponds of size 10ft into 30ft each. This is very tentative figure at the moment and likes to have participant's views for approximately estimated 5,000 gallons daily inflow.
