1. Development of Water Resources of Turag River and
their Management. – a concept paper.
1. Objectives- production of primarily drinking water for
Dhaka city dwellers.
2. Modus operandi - Participatory approach with local
people
3.Terms & conditions to be enforced-
(i) no disposal of industrial effluent in the river.
(ii) no encroachment /illegal occupation over the river or
foreshore.
(iii) if foreshore land is owned by private individuals, the
management of the foreshore land is to be vested with the
authority in lieu of annual benefit so harvested.
(iv) no access of the people and their domestic animals to the
river
(v) people having land location within 250 meters from the
foreshore of the river will be registered as participants of the
project. The net quantum of benefit without project (net
profit in terms of money) they obtained from their land
should also be recorded.
4. Project design. (design will be shown in sketch)
i)The soil excavated from the river bed will be used in
making bund at the outer border of both sides of the fore
shores or if bund /embankment is already existing, may be re-

2. enforced. There will be strong drainage system for run off of
rain water or irrigation water by pipe /culvert into the river.
Soil movement with the run off water will be checked by
putting wire mesh on the mouth of the pipe or by growing
long grasses.
ii)Water from the river will be lifted and stored in overhead
tank located on the rooftop of a house built for taking bath by
people. The washing of cattle and also washing of all
domestic goods etc will be done in an open platform. The
waste water will go for irrigation if necessary otherwise will
be drained out through filtered drainage system.
iii) Barrages will be built at such a height that flood season
water may over flow the barrage and sufficient water
remains stored in the project area for meeting the lean period
demand. There will be two barrages over river Turag one at
tentatively DIABARI west of Mirpur Mazar and another at
east or west of Tongi bridge depending on environmental
assessment.
iv) Silt trap will be built up steam at a suitable point of the
river and to the north of Tongi Ashulia Road.. There are
three stream fall there on the river and thus three silt trap are
to be built if silt is carried by water flow. The silt trap may be
constructed by using bioengineering technology. The trapped
silt will be sold out.
5.Implementation strategy.
i) legal provision should be made through legislative
assembly so that conditions are enforced for achieving the
objectives.

3. ii) land owners within 250 meters of foreshore and other
workers will be provided training for growing suitable agro-
forestry crop in such a pattern that soil erosion and sediment
deposition in the river bed does not take place.
iii) amphibian plants like Nalkhagra(Phragmites karka),Arum
(Colocasia esculanta), Dhuol Kalmi(Ipomoea fistulosa),
Mandar (Erythrina variegate) Ziaul vadi (Lannea
coromandelica) Jam (Syzygium grande/ cumini) Gab
(Diospyros peregrina) Pitali (Trewia polycarpa) are to be
selected among them on the basis of study of site condition.
iv) Management will be a continuous process. It includes
training of all participants about growing, nursing and
protection techniques.
• Planting design shown below are over land segments
belong to either private or public.
• Rain water on crop land run down to the river passing
over the agri cropped berm, upper slope covered by
sungrass, lower slope by amphibian plants on yhe sides
of the river.

A.Cost estimate for production of drinking water.
1. cost of motivation of the people, organize them into cooperative teams, one team
for one kilometer.
2. cost of the crop usually grow over the earmarked private crop land per km.
3. cost of growing agro forestry per km
4. cost of planting sungrass on the upper slope per km.
5. cost of planting amphibians on the lower slope per km.
6. cost of payment the value of the crop usually grow in earmarked private land.
7. cost of construction of silt trap
8. cost of costruction of barrage
9. cost of pumphouse and pump machine
10. cost of construction of drain and platform per km.
B. Benefits from the project.
1 value at site of the agri cop from second year per km
2. value of wood at every 10th
year per km
3. value of sungrass from second year/km
4 value of nalkhagra from second year/km.
5. value of irrigation water, showering facilities etc.
6 value of drinking water.
