说明:

(1) Total size of the project area = 4.75 Ha.
(2) Different structures taken up in the project area are
(i) Brushwood check dam- 6 Nos.
(ii) Drop structure- 8 Nos.
(iii) Dugout sunken pond - 1 No.
(3) All the above structures were positioned to ridge to valley treatment
(Ref.QT-6/2.1.2/a)

Purpose of the Technology: 1) Storage of runoff for cattle and human use.
2) Construction of structures to check soil erosion and sand casting.
3) Pisciculture.

Establishment / maintenance activities and inputs: Establishment :-
1) SWC specialist selected sites for dugout sunken pond, layout the design.
2) SWC specialist also selected sites for drop structures, brushwood check
dams in gullied portion of project area with reference to vertical interval
of slope gradient and space between structures.
3) The execution of work were done by concerned villagers on payment basis.
4) During execution, 20% of the total cost of the dugout sunken pond was
contributed by the villagers in shape of labour.
5) Training on technical know how imparted to the villagrs during execution
of pond, bund, drop structure and brush wood check dam.
Maintenance:-
1) The dugout sunken pond requires (a) Desiltation once in two years (b)
Repair of earthern bund around inlet and outlet every year.
2) The drop structure & brushwood check dams requires little maintenance when
ever requires.
3) One management group has formed in the same village & funds has been
raised by doing pisciculture in the pond.
4) The management group is taking major reponsibility for its maintenance.
