1. Introduction:
WaterAid is an international not-for-profit organization, established in 1981, determined to make clean water, decent toilets and good hygiene normal for everyone, everywhere within a generation. We change millions of lives every year, working in 28 countries to provide clean water, decent toilets and good hygiene.
Since we started in 1981, we’ve remained resolutely focused on tackling these three essentials that transform people’s lives. Without all three, people can’t live dignified, healthy lives. With all three, they can unlock their potential, break free from poverty, and change their lives for good. Children grow up healthy and strong, women and men get to earn a living, whole communities start to thrive. It sounds normal and it should be.
By inspiring people and sparking chain reactions we help deliver lasting change in what’s normal. By working closely with partners internationally and on the ground in some of the toughest places in the world, we help achieve widespread change. Millions of people have already taken control of their lives and built better futures.
WaterAid has been working in Nepal since 1987. Our work in Nepal spans across 4 districts. We team up with local partners, technical experts, governments, and communities to support the delivery of integrated WASH services in hard-to-reach communities, helping to transform lives.
2. Background:
WaterAid Nepal is currently implementing the Project entitled “The Beacon Project: Municipality Wide equitable WASH Services in Lahan: A joint initiative of Anglian Water, their Alliance partners, WaterAid, and Nepal Water Supply Corporation (NWSC)” in Lahan municipality, Siraha District of Nepal. The overall objective of the project is to support Nepal to achieve the Sustainable Development Goal for water and sanitation by implementing the WASH sector plan. The specific objectives are to:
- Model a municipal-wide approach in Lahan as part of the district-wide model for Siraha district.
- Support the efficiency and expansion plans of NWSC in Lahan with a focus to reach marginalized and poor communities
- Leverage the model in Lahan for district and national benefit.
In the current context of Nepal, where majority of the rural areas are in transition to transform to the small towns of municipal towns, their needs are also changing accordingly. In these contexts, the unsystematic and unsupervised borehole drilling and construction that were done in the past years needs to be changed and come up with new mode of thinking technically and systematically. In this regard, WaterAid visualized that the technical endeavours in borehole drilling, and its supervision is of paramount importance if one thinks of their sustainability and appropriateness technically.
Beacon project aims to support technically to NWSC to increase the efficiency of the existing tube well system and add four more deep tube wells to supply the safe water to the increasing population of Lahan Municipality.
3. Rationale:
Under The Beacon Project, one of the integral components is Water Resources. This component aims to ensure the improved water production, monitoring, and prevention of possible contamination. This can be attained with the greater functionality and sustainability of water sources which in Lahan mostly are boreholes. Under this component, Beacon project aims to support technically to NWSC in the construction of model boreholes in Lahan municipality for its replication and scalability to other branches and within Lahan as well.
It is crucial that boreholes are delivered in a cost-effective manner. Cost effectiveness means getting the long-term best value for money invested, i.e., boreholes continue to function through the lifespan of 20 to 50 years. One of the best ways to tackle the poor borehole construction is to improve the quality and professionalism of water well drilling including supervision (Rural Water Supply Network (RWSN), 2014). In addition, ensuring compliance with the relevant Nepal standards and/or Indian standards regarding the material quality also ensures the standardised product. Thus, it is desired to bring the competitive and excellent drilling company to undertake drilling and construction of Deep tube well for NWSC Lahan as part of support from Beacon project.
NWSC currently have six functional boreholes as their key production sources namely OC3, OC8, BHA2, TCN1, TCN2 and Ashram1 located at different locations. Discharge of each well is used to serve population. As per the increase in population additional tube well need to serve for the municipality.
Increasing population in the years to come may create water stress. Therefore, the need of water per household needs to decide the number of future tube wells. So, additional tube well needs for increasing population and rehabilitation of the existing well, if possible, could be the reasonable solution.
4. Objective:
The overall objective of the work is to improve the supply of safe water to the networks of NWSC Lahan. The specific objectives of the work will be to:
- Install four deep tube wells in four locations of NWSC Lahan facilities. (Refer Annex I - Detail technical specification and Bill of Quantities) (Refer Annex V – Maps showing location of proposed boreholes)
- Develop well and perform pumping test/recovery test as per the technical specification.
5. Scope of the Assignment
The scope of the contractor shall include, but not be limited to, the following activities over a period of 5 Months.
- Assure the timely installation of four Deep Tube wells at the locations provided by NWSC.
- The Vendor will follow up with the concerned authorities, legal, statutory, and administrative formalities, permits/approvals for delivering/installing the deep tube wells.
- Proper health and safety measures shall be ensured amongst the workers following the Government's and WAN's safety guidance for working during Covid-19 and Dengue situation.
- The Quality control will be made with the regular supervision by NWSC, WAN and Consultant.
