Eucalyptus has been used in Mukono (Uganda) and I hope Charles T (Kyambogo University) can comment on this work.
To M Jahangir
How would you transport effluent to the individual trees ?

Yes Eucalyptus trees are used in water logged soils but to protect them from being cut away by gypsies etc. You mean that stream may be lined with trees on both sides like on the highways. How to achieve necessary retention time for effluent for treatment? The plants are needed for aeration of the incoming sewerage water flow and need a minimum retention period before being discharged into the natural stream. How you intend to achieve this. The effluent can reach few Eucalyptus trees that are already planted there at the discharge point on the stream and for rest some other arrangements may have to be considered.

But planting on either side of the channel looks like a better choice.
This water need not be dumped into a fresh
water stream. It may spiral round the trees.
This will help meeting the big gap of area under forests in Pakistan.
Same time it will help recharge the aquifer.

To Jahangir
Q: how would you drip irrigate on the other side of the stream if you
plant Eucalyptus there ?
>..Same time it will help recharge the aquifer.
How would drip irrigation to Eucalyptus trees help recharge the
aquifer ? At what flow rate would it take for this to happen ?
Could you provide some costs analysis for drip irrigation for e.g. 100
Eucalyptus trees ?
thanks
