PROCURING ENTITY: PARTNERS IN HEALTH/ABWENZI PA ZA UMOYO

DUE DATE : 20 February 2026

TIME : 1700 Malawi Time (GMT +2)

Partners in Health Malawi, locally known as Abwenzi Pa Za Umoyo (PIH/APZU), is a local non-governmental organization (NGO) which has accompanied the Ministry of Health and Population (MoH) since 2007 in Malawi. Our mission is to create a preferential option for the poor in health care by accompanying the public sector in strengthening the provision of essential health services. (PIH/APZU), through the Non-Negotiables Phase 2 Program, invites tenders for the custom process design, supply, installation, and commissioning of a complete water treatment system, including an integrated waste disposal solution, for the purpose of upgrading a reticulated borehole water supply system to provide portable drinking water for a health facility in the rural district of Malawi.

The scope of works is as stated below:

1. Project Overview: PIH/APZU intends to engage a qualified and experienced service provider to design, supply, install, and commission a complete water treatment system capable of removing heavy metals (including iron, manganese, arsenic, and lead), reducing salinity, and providing post-treatment chlorination to produce potable water compliant with the WHO Guidelines for Drinking-water Quality. The entire system must be sized to produced 6m³ potable water per 8-hour work day, accounting for standard peak demand, storage buffer and minimum operational time, and must consistently produce final effluent that meets or exceeds WHO drinking water quality standards for each of the parameters and enables free residual chlorine to remain within a range of 0.2-0.5mg/L at all points of consumption i.e. there is no mineral content in the potable water that interferes with the chemical action of chlorine disinfection.

2. Qualification Requirements for award include amongst others: Ø The bidder shall demonstrate a minimum of five (5) years of specialized experience in designing and engineering integrated water treatment systems, with proven expertise in configuring treatment processes for effective removal of heavy metals (including iron, manganese, arsenic, and lead) and reduction of salinity. Experience with relevant technologies used to treat water with similar quality challenges will be considered, the requirement is to install a system that delivers water that meets or exceeds WHO drinking water guidelines. Ø The bidder shall provide evidence of at least three (3) years of field experience within the past eight years, implementing projects of similar complexity in African or similar resource-limited settings. Experience should specifically include the design, installation, and commissioning of multi-stage water treatment systems for heavy metal removal, with preference given to projects in healthcare or similar institutional environments in rural or off-grid locations. Ø The bidder shall submit three (3) project references from organizations they have done similar projects for. PIH/APZU reserves the right to conduct site visits at bidders’ previous projects to evaluate the quality of installations, or to sub-contract a 3rd party to conduct such site visits.

Our mission is to create a preferential option for the poor in health care by accompanying the public sector in strengthening the provision of essential health services through; 1) Strengthening human resources for health by providing essential staff and providing high quality capacity building to health care workers; 2) Supporting the provision of essential health infrastructure to allow comprehensive provision of care; 3) Supporting essential equipment, supplies and medication; 4) Working with MoH to create and strengthen systems that will improve the quality of care; and 5) Providing social support to vulnerable patients. Our staff and beneficiaries have a right to protection and as a humanitarian organization, Partners in Health Malawi has an obligation to make sure that we safeguard the children, vulnerable adults and entire communities that we work with. It is the responsibility of all of our staff, representatives, partners including suppliers, contractors, vendors and service providers to ensure that we serve the needs and protect the well-being of children and vulnerable adults to whom we have a special duty of care, including those with whom we work with, are in contact with or who are affected by our activities. For this reason, we have policies and systems in place to prevent abuse, neglect and exploitation and to safeguard children and vulnerable adults (detailed in our PSEAH Framework). These measures also protect contractors, vendors and service providers from actions that could be misconstrued and lead to false or malicious accusations. Being contracted to support PIH Malawi’s projects is an opportunity to contribute to our overall mission and we would like you to enjoy your work and at the same time help us to keep children and vulnerable adults safe by introducing you to the key elements of our policy that affect you as a contractor or service provider.

Definition of child and vulnerable adult A child is a person under the age of 18 years, according to the United Nations Convention on the Rights of the Child (Article 1).
