Introduction

Team of researchers and development practitioners from three regional institutions namely Research Development and Training Center Outreach, Savannakhet University (RDTC-SKU) Lao PDR, Division of Research and Development Sleumprakiat Campus Kasetsart University (DRD-KU) and Hue Institute of Technology Vietnam received  a competitive fund to implement a development project entitled “Community Water Resource-based Agriculture and Fishery Development (CWAFD), with a main object of strengthening rural household farmers in community water resource management in  the three regions of three country (Savannakhet and Khammouane province (Lao PDR), Sakon Nakhon province (Thailand) and Hue province (Vietnam).  One of CWAFD Project objective is to design 4 Community Fish Pond (CFP) with of 70 meters in length, 70 meters in width, and 3 meters in height with embankments sloped 35–45 degrees and pegs 3 meters. 

This Terms of Reference (TOR) is issued to outline the scope, objectives, and deliverables for the design and development of 4 community fish pond(CFP)) in project site.

The proposed weir shall have approximate dimensions of 70 meters in length, 70 meters in width, and 3 meters in height with embankments sloped 35–45 degrees, spare 3meters for pegs. The primary purpose of the CFP is to regulate water flow, support water management objectives, and ensure operational safety in accordance with the specified environmental and hydrological considerations. The design process will encompass hydraulic, structural, and environmental aspects to ensure a resilient, efficient, and compliant structure capable of meeting the project’s overall goals.

I. Background and Context

A Community Fish Pond (CFP) serves as a key infrastructure for promoting rural livelihoods, supporting sustainable aquaculture, and strengthening community-based food security. The proposed CFP, with dimensions of 70 meters by 70 meters and an average depth of 3 meters, is designed with embankments sloped between 35 to 45 degrees to ensure stability, safety, and efficient water retention.

This pond will be developed as part of the Community Watershed-Based Agriculture and Fishery Development Project in Project areas. It will provide a reliable source of fish production, water storage for dry-season farming, and ecological benefits such as groundwater recharge and biodiversity conservation. The design will emphasize technical soundness, environmental sustainability, and community participation, ensuring long-term usability and local ownership.

This Terms of Reference (TOR) defines the objectives, scope of work, methodology, deliverables, and timeline for the design and planning of the CFP. It will guide the consultants or engineering team responsible for delivering the design and implementation framework.

II. Objectives

• To design a technically sound and environmentally sustainable community fish pond with the specified dimensions.
• To ensure the pond’s design supports efficient water storage, aquaculture productivity, and safety.
• To suggest about natural fish migration and its habitat
• To prepare detailed engineering drawings, cost estimates, and construction guidelines.
• To integrate environmental and social safeguards into the pond design and management plan.

III. Scope of Work

• Conduct topographical and geotechnical surveys of the proposed site.
• Assess hydrological and soil-water conditions to determine water retention capacity.
• Design pond structure, embankment slopes, inlet/outlet systems, banks (including prevent soil erosion) and drainage facilities.
• Prepare detailed drawings and technical specifications suitable for construction.
• Site identification and considering about natural fish migration during reproduction periods
• Estimate project costs and prepare a Bill of Quantities (BoQ).
• Develop operation and maintenance (O&M) guidelines for long-term management.
• Ensure compliance with local environmental, safety, and construction standards.

IV. Methodology for the Design of Community Fish Pond (CFP)

The methodology describes a systematic approach to developing the pond design with dimension 70x70x3 meters, banks and pegs (3m), ensuring technical accuracy, environmental responsibility, and stakeholder engagement.

4.1 Data Collection and Site Investigation

1. Topographical Survey:
• Conduct detailed topographic mapping of the proposed site to determine elevation, drainage patterns, and pond layout feasibility.
• Identify water inflow and outflow points to ensure natural water balance.
2. Geotechnical Investigation:
• Perform soil testing to determine permeability, stability, and suitability for pond construction.
• Evaluate the soil’s compaction properties to design durable embankments.
3. Hydrological Assessment:
• Assess local rainfall patterns, runoff potential, and water source reliability.
• Estimate pond water storage capacity and seasonal variation.

4.2 Environmental and Social Assessment

• Identify potential environmental impacts such as erosion, water pollution, or habitat disturbance.
• Propose mitigation measures (e.g., vegetative buffer zones, sediment traps).
• Engage with community members to incorporate local knowledge and ensure shared ownership of the pond.

 

4.3 Engineering Design and Analysis

1. Pond Layout Design:
• Design a square pond (50m x 50m) with 2.5m depth, considering optimal water surface area and embankment stability.
• Design embankments with slopes between 35°– 45°, reinforced with grass or local vegetation to prevent erosion.
2. Inlet and Outlet Structures:
• Design controlled inlet and outlet systems to regulate water levels and prevent overflow or seepage.
• Include spillways or drainage channels for excess rainwater discharge.
3. Structural Stability:
• Ensure the pond’s design can withstand hydrological pressure, rainfall impact, and sediment accumulation.
• Include measures for pond lining or clay compaction if required.

4.4 Environmental and Social Integration

1. Environmental Protection:
• Integrate soil conservation and reforestation around the pond area.
• Develop erosion control and water quality management measures.
2. Community Engagement:
• Encourage community participation in design validation and future maintenance.
• Provide awareness on sustainable fishery management and water use practices.

4.5 Design Documentation and Verification

1. Preparation of Design Documents:
• Prepare engineering drawings showing pond layout, cross-sections, inlet/outlet design, and embankment details.
• Develop a Bill of Quantities (BoQ) and detailed cost estimate.
2. Design Review and Verification:
• Conduct internal technical review and peer validation to ensure design reliability.
• Confirm compliance with national construction and environmental standards.

4.6 Operation and Maintenance (O&M) Planning

1. O&M Manual Development:
• Prepare a comprehensive manual covering pond operation, routine maintenance, water level control, and fish production practices.
2. Training and Capacity Building:
• Conduct training for community groups or local leaders on pond management, water quality monitoring, and fishery practices.

V. Reporting and Deliverables

Final Deliverables:

• Inception report and site survey summary (Day 1–2)
• Detailed engineering drawings and pond layout (Day 10)
• Environmental and social impact summary (short report)
• Cost estimates and Bill of Quantities (BoQ)
• Operation and Maintenance Manual
• Final Report (maximum 30 pages, excluding drawings) by Day 20

VI. Timeline and Milestones
