DPR Preparation of a Dam and Artificial Lake in Jiri Municipality

  • Project: Preparation of DPR of Dam and Artificial Lake
  • Client: Jiri Municipality
  • Location: Jiri Municipality, Dolakha District, Bagmati Province
  • Date: July 2019 to June 2020

The project consist of preparation of Detail project report (DPR) which comprises of feasibility analysis and execution plan for the construction of dam and recreational lake, Tourism Development and Management Plan, Spatial Development Framework for the Jiri Valley. The consultant has completed all the assignment as per ToR.

The proposed Jiri Dam and Artificial lake is located in Jiri Municipality of Dolakha District, Bagmati Province, Nepal. The project area can be reached through 188 km Kathmandu-Lamosangu-Jiri road. The Jiri Dam is Concrete Gravity Dam of 38 m height and 8 m top width and an Artificial Lake formed by the Dam will have reservoir surface area of 123,685.53 m2.  

Overall Services provided by firm

The scope of work broadly include two segments. The first includes preparation of detail project report (DPR) which comprises of feasibility analysis and execution plan for the construction of dam and recreational lake, and the second includes preparing plan framework to guide tourism and urbanization in Jiri Valley. The summarized scope performed by the JV company includes the following activities:

  • Detail project report (DPR) which comprises of feasibility analysis and execution plan for the construction of dam and recreational lake

    • This output contains two parts - feasibility assessment comprise of technical, environmental, social, financial, economic feasibility studies and risk assessment.

      • The technical feasibility assessment provide recommendations on site suitability, geological condition and type of the dam. As part of the feasibility assessment, an access route map is prepared in accordance with the Guidelines for the study of Hydropower Projects. Likewise, a showing physiographic regions, control survey maps showing benchmarks, drainage basin map, flow duration curve, reference hydrographs, regional geological maps, site specific geological maps, seismicity map, and powerhouse switchyard layout are also required. The technical feasibility recommend development of serviced land for planned settlements for the beneficiaries using land polling as an appropriate land development mechanism.

      • Environmental feasibility study include impacts of the project on the river ecology, land and cultural landscapes.

      • Social feasibility study contain benefits and implications caused by the project on the beneficiaries and their livelihoods.

      • Financial feasibility outline means of accruing investment from various sponsors along with the net financial benefits for the municipality and profitability and cost-benefit analysis include in economic feasibility. The risk assessment includes norms and standards for safety, adaptation and mitigation measures against all the pertinent risks.

    • The feasibility assessment report contain recommendations on the viability of the project and also on alternative forms.

    • The execution plan contain detailed engineering design of dam structure (Height of dam 38 m), detailed cost estimate, implementation model, implementation schedules and institutional arrangement revealed in flow chart. This plan also recommend an operation and management plan for effective operationalization of the built infrastructures, their repair and maintenance and delivery of services. The engineer’s estimate of dam construction for developing the recreation lake is NRs. 1,797,941,333.64 with all taxes, VAT and contingences.

    • The DPR contain reports of all the tests conducted for feasibility assessment (Soil investigation (65 m total depth - 25 m one bore and 20 m two bores) and Two-Dimensional Electrical Resistivity Tomography (2D-ERT). It contain all engineering drawings including details of mitigation measures against potential risks and comprising of detailed account of households and property losses including cadastral maps surveyed by the team showing areas that will be submerged (i.e. Water storage area map) and need to rehabilitate.

  • Tourism Development and Management Plan

    • Tourism Development and Management Plan contain recommendations on three major aspects.

      • First, the Plan recommendation on transportation measures such as improving road quality and standard and air service in order to enhance access to Jiri Municipality. These measures need to be intended for both domestic and international tourist.

      • Second, the Plan is required to identify major potential sectors of Jiri apart from its natural environment and heritage with careful examination of other tourist attraction in the valley and the vicinity. Potential tourism sites are depicted in maps. The Plan integrate tourism products with overall local economy and employment opportunities to create greater synergy, thus reduce outmigration trend. Following thorough assessment of tourism market segment, the Plan devise strategies to attract domestic tourists mainly from Kathmandu and other regional centers, western trekkers interested in short treks, and high spending resort tourists.

      • Finally, the Plan duly emphasize on valley wide environmental conservation. This include conservation of natural environment in the vicinity of the lake, upstream and downstream and also conservation of natural and cultural landscapes including promotion of traditional architecture and heritage.

    • Capital investment Plan (Short term, Mid term and Long term) is prepared for tourism development indicating the financing institution.

  • Spatial Development Framework for the Jiri Valley

    • This output include development framework, comprising of brief situation analysis, identification of opportunities and challenges, long term development vision, goals and objectives, strategies, operational policies and instruments and key development initiatives. The framework also include concurrent spatial structure drawn map - which reveals a hierarchy of activity nodes, connectivity, land classification (consisting of growth promotion areas including built area, future expansion area and growth discouragement areas including natural resources areas), special environment management area such as eco-corridor and buffer space and siting of key public facilities.

    • The framework contain detail local area plan containing a planned layout and permitted land use around the rim of the proposed lake. Such plan is prepared using land pooling technique, so that all landowners of the area duly rehabilitated. Details on land contribution and tentative sites for serviced land parcels to rehabilitate affected landowners are identified. The framework is augmented by appropriate planning and building bye-laws, environment thresholds, and infrastructure norms and standards.

    • The framework recommend key development interventions including basic urban amenities and facilities in nearby Yelun and Pumpa Valley (in East and Sikri Valley (in West).

    • The execution plan of spatial planning contain detailed engineering design, drawings and cost estimate of Administrative building, Boundary Road, Foot Trail, Suspension Bridge, Toilet, Parking, Entrance Gate, Lease Plot, Land Development and landscaping, View Deck, Horse Shed and other facilities.

    • Recommendation for the Investment Options to implement the Lake Area Development Plan.
