This Subunit Implementation Plan (SIP) elaborates the Feasibility Study that was done in 2013 at the level of (hydrological) subunit. It assesses the development options with regard to Water infrastructure, Operation & Maintenance, Agriculture, Fisheries, and Income generation and gender. It also considers safeguards in respect of indigenous people, the poor and vulnerable, and environment.


The subunit area is located in the SW part of Faridpur District and comprises 3,398 hectare, 13 WMGs with 33 villages. There are 7,391 households with a population of 33,662. Administratively the area is covered by 3 unions namely Alfadanga, Gopalpur and Tagarbandh along with the Alfadanga Pourasava.

Water management

The water infrastructure will benefit from a major overhaul: new construction of two regulators rehabilitation of three structures and re-excavation of khals over a total length of 8 km will reduce flooding and drainage congestion and thus benefit agricultural production. A retired embankment over a length of 1.45 km needs to be constructed and carpeted. Further an embankment needs to be re-sectioned over a length of 0.792 km. The cost of rehabilitation is estimated at some Tk.1,133 lac.

Operation and Maintenance

The Water Management Association of the subunit will sign an Agreement with the XEN-BWDB about sharing O&M responsibilities. Operation of the infrastructure will be decided by the Water Management Association at subunit level.

A Maintenance Plan for the subunit-III has been formulated where responsibilities have been delineated and costs for maintenance worked out. The total cost of preventive and periodic maintenance for subunit-III has been estimated as Tk. 36 lac per annum of which WMA share would be Tk. 7 lac with BWDB bearing Tk. 29 lac. The WMA/ WMG share comes to Tk.113/ ha/ year. The cost of WMO training has been estimated at about Tk. 12 lac.


The gross area of the Barobag Sub-unit (SIP-3) is 3,398 ha. and net cultivable area is 2,820 ha.. Present cropped area is 6,118 ha. with a Cropping Intensity of 217%. The future total cropped area has been estimated at 7,366 ha. with a Cropping Intensity of 261%. Production of cereal crops will be increased by 9,290 metric tons (118%) and other crops by 1,878 metric tons (22%) with overall increase in production by 11,167 metric tons (68%) after rehabilitation of the Sub-project. Rice production has been estimated to be increased from 7,797 to 17,054 MT per year with an additional increment of 9,257 MT representing an estimated added value of Tk 2083 lac.  Average yield of rice has been estimated to be increased from 2.8 ton per ha. to 4.39 ton per ha.

To improve the existing agricultural conditions and to transfer the modern technology to the farmers’ level Training, Demonstration, Farmers’ Field School (FFS), Workshop, Fair and Motivational Tour have been planned for implementation by the project. The costs of agricultural development (enhancement) activities of the SIP have been estimated at Tk. 31.73 lacs for the entire project period.


There are about 795.70 ha of fisheries resource in the sub unit area among them 168.20 ha in culture fisheries and rest of 627.50 ha in capture fisheries, and estimated total production is 515.20 MT / year (Table - 01, Annex - 4). Culture fish production can be increased from 435.45 MT to 659.70 i.e by 224.25 MT but capture fish production will be decreased from 79.75 MT to 38.23 MT i.e by 41.52 MT, after rehabilitation of this sub unit area and total annual incremental benefit would be Tk. 13.98 lac (Table - 3, Annex-4).

Financing of the fisheries activities would require both beneficiary and project contributions. Beneficiaries will be responsible for all direct inputs cost required for fisheries production, both culture and capture because they will manage the activities through CAPs. The project will bear the cost of demonstration, basic training, refreshment training and motivational tour. The training cost (excluding preparation of modules) amount to some TK.36.95 lac (Table 04, Annex -4)

WMO formation and development: 

WMO formation process commenced with mobilizing Facilitators and awareness creation. Union-level consultation were conducted and consent for rehabilitation work has been obtained from the communities. As the population has increased significantly since the Feasibility Study (FS) time, the project “re-demarcated WMG areas”. Consequently, the total number of WMGs increased from 7 (at FS stage) to 13. Elections were held and all the WMGs have been formed.

Participatory mechanisms will be adopted for developing and reaching consensus on “WMG-wise water and land use plans”, mainly for crops, fishery and other IGAs. Facilitators guided by ISPMCs and PMO staff will assist WMGs to implement these Plans. Sub-committees are established “focussed attention” on specific tasks of WMO. There will be O&M Agreements between WMA and BWDB.

ISPMCs and PMO will conduct Quarterly “Participatory Performance Assessment and Target Setting” (PPATS) sessions with Facilitators and WMO Monitors to assess their performance as well as the success of WMO development activities. PPATS would be introduced to WMOs as one of “exit strategies” and for ensuring sustainability of WMOs. Strengthened WMOs would effectively undertake their primary functions like Operation and Maintenance (O&M) of infrastructure, providing production and related services in agriculture and fishery, livestock as well as other livelihood activities.

Socio-economy and Gender

The total number of households of the surveyed area of SIP-3 is 7391 and population is 33662. The sex ratio, defined as the number of males per 100 females is 52% male against 48% female. The average household size of the surveyed households is 4.19.The working age group of the surveyed population is about 60%. The non-productive population involves those who are able to work but enjoy social benefit at the cost of productive people. Generally, children younger than 17 and adults older than 61years are considered non-productive people. The percentage of female headed and male headed household is 7.38%, who are widow, separated, live with disabled husband and survive with their own income. Farming is the main occupation of all categories of farmers 42.38%, followed by business 22.51%, services 1.24%.The other occupation10.48% which includes; daily wage  laborers, fishermen, hawkers, traders. The normal poverty level of the SIP-3 of Alfadanga-Boalmari area is in between 40%-45%, which is much higher than the national average of 34% (BBS,2011).  A total Tk.29.22 Lac is proposed for the improvement of gender and livelihood situation in SIP-3 area.


Lastly, a monitoring plan is given in order to monitor the progress of WMO formation and development, as well as the outcome (results) of the Subunit Implementation Plan.
