Background:

Heifer Project International Nepal (HPIN) is implementing a signature program “Milky Way- Transforming Dairy sector of Nepal”. Under the initiatives, there is a plan for establishing Model Dairy Village (MDV) cum Elite Nucleus Herd of dairy cattle with support of high-quality heifers (HF) from Heifer Korea. For dairy farming, adequate and regular supply of water for drinking to the animals; cleaning of shed, animals and dairy equipment; and irrigation of forage field are pre-requisite for success of dairy animal farming.

• Review and upgrade the existing water supply system design up to reservoir tank (RVT), drawings and cost estimation.
• Assess existing water supply structures in terms of their reuse in case of rehabilitation of existing systems.
• Carry out detailed engineering and socio-economic survey, prepare checklist for environmental parameters of the project area.
• Verify the source yield, water quality, intake/sump well site, reservoir site, pipe alignment and number and location of house connection and other major structures.
• Clarify the community enthusiasm on the execution of the project and willingness to contribute for construction and undertake operation and maintenance responsibility upon commissioning.
• Prepare detailed water supply project report for the selected Sami Khahare Lifting Water Supply Project.

2. Methodology:

The consultant shall submit proposal for the study explaining in brief their capacity and experience to undertake the job, methodology to be applied and cost required for detailed engineering study and design report for each project. The selection criteria of the consultant shall be based on technical & financial proposal; however, other relevant factors shall also be considered.
