ToR - Installation of Tube Well Boaring

Installation of Tube Well Boring

in Drought-Affected Areas

1. Introduction

1.1 A Brief Introduction of KSSC-NEPAL

Kalika Self-Reliance Social Centre (KSSC-Nepal) has been actively engaged in community development and social transformation for over three decades. The organization has implemented a wide range of programs and projects across the Koshi and Lumbini Provinces. Currently, KSSC-Nepal is working in 48 local governments across eight districts of Lumbini Province. Over the years, the organization has focused on thematic areas such as education, health, nutrition, WASH, MNCH, child protection, gender-based violence reduction, poverty alleviation, women’s empowerment, awareness raising, and emergency response. At present, KSSC-Nepal is implementing the “Groundwater Monitoring in Drought-Affected Areas” project in partnership with UNICEF.

Due to prolonged drought conditions, groundwater levels have significantly declined in terai region. With technical studies and to observe the issues, Banganga Municipality of Kapilvastu District has been selected for establishment of ground water monitoring system to ensure sustainable access to safe drinking water for affected communities. The declining water table and increasing stress on existing water supply systems have created an urgent need for systematic groundwater monitoring to understand aquifer behavior and ensure long-term access to safe drinking water for affected communities.

Mentioned all the areas are characterized by multi-layered alluvial aquifer systems consisting of shallow, intermediate, and deep groundwater horizons. In order to properly assess groundwater dynamics and avoid hydraulic mixing between aquifers, each selected monitoring location will require the installation of three dedicated observation tube wells:

• One in shallow layer
• One in the intermediate layer
• One in deep layer

Each tube well to be constructed shall be single-screened, targeting only its respective aquifer layer. This design approach is essential for generating reliable water-level and water-quality data and for monitoring aquifer-specific responses to abstraction and recharge processes.

To implement this initiative, KSSC-Nepal, Kapilvastu invites qualified and experienced national-level contractors/firms to submit bids for the Installation and construction of two sets of Tube Wells for groundwater monitoring with automatic water level monitoring censor in the above-mentioned areas. Thus, based on the specifications, requirements, terms, and conditions set forth in this Bid document, this Bid intends to enable KSSC-Nepal, Kapilvastu to identify qualified suppliers from the national Level) for the supply of the above-mentioned stationery items. The Bid describes our current understanding of our needs however these needs and specifications can be changed if KSSC-Nepal, Kapilvastu feels necessary.

1.2 Summary of Bid

The objective of this bid is to select a technically competent and experienced contractor for:

• Design, drill, and install single-screened shallow, intermediate, and deep tube wells
• Preparation of detailed lithological logs during drilling
• Installation of a properly graded gravel pack
• Sealing using bentonite to prevent vertical aquifer interaction
• Construction of a reinforced concrete platform
• Installation of flange/ Well cap with locking arrangement
• Well development
• Conduct pumping tests and provide analytical interpretation
• Collection of groundwater samples for the water quality testing

The details are provided in the scope of the work

The contract shall be awarded based on technical qualification and financial evaluation.
