How to Source WASH Supplies for Emergency Response in South Sudan: A Procurement Guide for NGOs and UN Agencies

For logistics officers, program managers, and procurement teams working in South Sudan, sourcing WASH supplies under emergency conditions is one of the most operationally demanding challenges in humanitarian response. Flooded access routes, cholera outbreaks, limited in-country stock, and tight donor timelines create a procurement environment where every decision carries life-or-death consequences.

This guide is designed to help NGOs, UN agencies, and government responders navigate WASH procurement in South Sudan more effectively — covering pre-positioning strategy, lead time realities, supplier selection criteria, and why a locally rooted, authorized distributor makes a measurable difference.

1. Understanding the WASH Procurement Landscape in South Sudan

South Sudan presents one of the most complex humanitarian operating environments on the continent. Persistent conflict, seasonal flooding, crumbling road infrastructure, and recurring disease outbreaks mean that demand for WASH supplies is not only high — it is chronically urgent.

According to the OCHA South Sudan Humanitarian Needs and Response Plan (HNRP) 2025, over 9 million people require humanitarian assistance, with water, sanitation, and hygiene consistently among the top three priority sectors. The cholera outbreak that began in late 2023 has continued to strain WASH response capacity, with case counts reaching into the tens of thousands across multiple states.

For procurement teams, this context creates several compounding challenges:

•        Unpredictable demand spikes: Cholera outbreaks, flooding events, and population displacement can trigger emergency procurement requirements with lead times of 24–72 hours — far shorter than standard international supply chains can support.

•        Infrastructure constraints: Seasonal road closures cut off large portions of the country between May and November, making pre-positioned stock in-country a logistical necessity rather than a convenience.

•        Customs and import delays: As noted by the Institute for Security Studies (ISS), fragile states like South Sudan face "customs delays and lack of last-mile delivery systems" that regularly cause critical stockouts, even for high-priority WASH items.

•        Compliance requirements: Donors including USAID/BHA, ECHO, and UNOCHA require procurement to align with Sphere standards, cluster coordination frameworks, and approved vendor lists — adding procedural complexity to already challenging operational timelines.

2. The Case for Pre-Positioning: Why Timing Determines Outcomes

One of the most consistent findings in humanitarian logistics research is the critical importance of pre-positioning. The South Sudan Flood Preparedness and Response Plan (Logistics Cluster/OCHA) identifies pre-positioning, warehousing, and mobility as "core enablers of the response, not support functions" — a framing that should shape procurement strategy from the earliest stages of programme planning.

When WASH supplies are not pre-positioned in-country before the onset of the rainy season (typically April–May), response agencies face a narrowing window to procure, ship, and deploy. International shipments from Europe or the Middle East typically carry lead times of 4–8 weeks under optimal conditions. In a country where roads can become impassable overnight, this is often too long.

Pre-positioning strategy should address three key questions:

•        What to stock: Prioritise fast-moving, high-consumption items — water purification tablets (Aquatabs, P&G Purifier of Water), Oxfam steel tanks, flexible bladder tanks, hygiene kits, and jerricans. Align product selection with WASH Cluster guidance and Sphere minimum standards.

•        Where to stock: Identify logistics hubs and displacement sites with reliable access windows before the rainy season. Work with the Logistics Cluster South Sudan to map priority storage locations.

•        How much to stock: Model stock requirements against the number of people in need in your area of operation, applying Sphere standards (e.g., minimum 15 litres of safe water per person per day). Build in a buffer for demand spikes driven by disease outbreaks or sudden displacement.

Why Local Distribution Beats International Procurement for Emergency Response

Sourcing WASH supplies through an in-country authorized distributor — rather than procuring internationally and shipping to Juba — offers four concrete advantages in emergency response settings:

•        Speed: A local distributor with in-country stock can fulfill orders in days, not weeks. In a cholera response, this difference is measured in lives.

•        Reduced customs risk: Items already cleared and warehoused in South Sudan eliminate the risk of customs delays holding critical supplies at the border.

•        Cost efficiency: Consolidated procurement through a local authorized distributor avoids per-unit air freight surcharges and last-minute emergency sourcing premiums that can add 30–60% to unit costs.

•        Technical support: An authorized distributor can provide product specification support, training, and after-sales service — particularly important for pump equipment and water storage systems deployed in remote field conditions.

3. Core WASH Product Categories: What to Procure and Why

Effective WASH procurement for emergency response in South Sudan typically spans five core categories. Understanding the use case, shelf life, and logistical requirements of each helps procurement teams build coherent, Sphere-aligned supply packages.

Water Purification Products

Water purification is the foundation of any emergency WASH response. In South Sudan, two products dominate the humanitarian pipeline:

•        Aquatabs (Sodium Dichloroisocyanurate tablets): The global standard for point-of-use water chlorination. Used extensively by IOM, UNICEF, and MSF in cholera response operations across South Sudan. Effective for relatively clear water sources. Available in multiple tablet strengths for household and community-scale use. Distributed through the IOM NFI and WASH pipeline for cluster-coordinated responses.

•        P&G Purifier of Water (PUR sachets): Combines flocculation and disinfection in a single sachet, making it effective for highly turbid surface water — common in flood-affected areas. Particularly valuable in the Greater Upper Nile and Jonglei regions during flooding seasons when river water is the primary source. SLS has direct experience deploying P&G PUR sachets in South Sudan cholera responses, as documented in our P&G Cholera Response case study.

Water Storage Systems

Adequate, safe water storage is as critical as purification. Two systems are standard across humanitarian operations:

•        Flexible Onion/Bladder Tanks (Butyl Products): Collapsible, rapid-deployment tanks ranging from 500L to 10,000L+. Ideal for temporary displacement sites, health facilities, and distribution points. Manufactured by Butyl Products UK, SLS's authorized distribution partner. Can be deployed by two people without heavy equipment.

•        Oxfam Steel Tanks: Bolted steel tanks for semi-permanent or long-duration deployments. Higher upfront cost but greater durability for protracted crisis settings or health facility water supply. Also supplied through Butyl Products.

Hygiene Items and NFIs

Beyond water treatment and storage, a complete WASH response requires hygiene non-food items (NFIs): soap, jerricans, buckets with lids, and menstrual hygiene materials. These items should be procured as part of an integrated package aligned with WASH Cluster minimum standards, and should be ready to distribute immediately upon deployment.

Pump Equipment

Dewatering and submersible pumps are increasingly critical WASH infrastructure in South Sudan, where seasonal flooding contaminates water points and compromises sanitation facilities. Multiquip and Aussie Pumps — both distributed by SLS — provide reliable, field-proven solutions for dewatering, water abstraction, and emergency water supply in the most demanding conditions.

4. Navigating the Procurement Process: A Step-by-Step Framework

For NGOs and UN agencies procuring WASH supplies in South Sudan, the following framework helps structure the process from needs assessment through delivery.

Step 1: Needs Assessment and Sphere Alignment

Begin with a population-based needs assessment, applying Sphere Handbook minimum standards as the baseline:

•        Minimum 15L of safe water per person per day for survival needs

•        One toilet per 20 people (maximum) at displacement sites

•        One hygiene kit per household for the first 30 days of an emergency

Map these requirements to your specific geographic area and population caseload to develop a bill of quantities (BoQ).

Step 2: Supplier Identification and Due Diligence

For procurement in South Sudan, suppliers should be assessed against:

•        In-country stock availability and typical fulfillment lead times

•        Authorization status for key product brands (Aquatabs, P&G PUR, Butyl Products, Multiquip, Aussie Pumps)

•        Compliance with donor procurement requirements (USAID, ECHO, UN agency vendor registration)

•        Track record with comparable organizations in the region (references from IOM, UNMISS, WHO, or major NGOs)

•        Registration on UN Global Marketplace (UNGM) or equivalent procurement portals

Step 3: Framework Agreements for Recurring Procurement

For organizations with multi-year programs in South Sudan, establishing a framework agreement with a local WASH supplier is strongly recommended. Framework agreements offer:

•        Pre-agreed pricing for standard product lines, reducing negotiation time during emergency activations

•        Priority fulfillment for signatory organizations over spot-market buyers

•        Simplified procurement authorization under donor rules (single procurement process covers multiple orders)

The South Sudan NGO Forum tender portal and the UN Procurement portal are useful resources for identifying vendor registration requirements and standard procurement procedures in South Sudan.

Step 4: Logistics Planning and Last-Mile Delivery

Even with supplies secured, last-mile delivery to field locations remains the defining challenge. Key considerations:

•        Access windows: Identify the latest safe date for road delivery to your area of operation before seasonal road closures. For many locations in Greater Upper Nile, Jonglei, and Lakes states, this window closes as early as May.

•        Air freight contingency: For remote locations accessible only by air during the rainy season, factor in UNHAS cargo allocation timelines and per-kg costs when budgeting WASH supplies.

•        Barge and river transport: The Nile and its tributaries provide an alternative logistics corridor for some locations. River transport can reach communities inaccessible by road during flooding — but requires early planning and coordination with river transport operators.

•        Warehouse staging: Pre-position supplies at a staging warehouse in Juba or a field logistics hub (Malakal, Bentiu, Bor) before road closures. SLS maintains warehouse capacity in Juba for client pre-positioning arrangements.

5. Working with Authorized Distributors: The SLS Advantage

Specialized Logistics Solutions (SLS) was established to address precisely the gap that procurement teams encounter when sourcing WASH supplies in South Sudan and the wider East and Central Africa region: the gap between international product availability and in-country operational reality.

As an authorized distributor for Butyl Products UK (water storage and purification), Multiquip, and Aussie Pumps, SLS maintains in-country stock and can provide:

•        Fast fulfillment of water purification tablets, bladder tanks, Oxfam steel tanks, and pump equipment from Juba-based warehouse stock

•        Technical specification support to help procurement teams select the right product for their specific operational context

•        Delivery and logistics support to field locations across South Sudan and the region

•        Documentation packages aligned with donor and cluster reporting requirements

•        Pre-positioning arrangements for organizations seeking to secure stock ahead of the rainy season

SLS has supplied WASH equipment and emergency relief items to IOM, UNMISS, WHO, and multiple international NGOs across South Sudan. Our case studies — including the P&G Cholera Response in Juba and the Aquatabs Cholera Response — document what effective, rapid WASH supply looks like in practice.
