South Sudan's government and humanitarian partners are seeking fresh investment in water treatment and distribution infrastructure to widen safe drinking-water access, with the country's rural, flood-prone and displacement-affected communities named as priority areas, in a report published 20 October 2026 (Africa Sustainability Matters). The push targets the country's substantial surface-water resources, much of it within the Nile River Basin, and aims to strengthen the water utilities that deliver treated water to households, the report said (Africa Sustainability Matters).
Key takeaways
- South Sudan is seeking greater support to expand water treatment and distribution infrastructure, with rural, flood-prone and displacement-affected communities flagged as priority areas (Africa Sustainability Matters).
- The Nile River Basin covers 97% of South Sudan, while national figures cited in the US government's 2023 Global Water Strategy country plan put basic water access at 41% — 70% in urban households and 34% in rural households (Africa Sustainability Matters).
- A solar-powered conventional water treatment project in Bor, Jonglei State, lifted safe-water coverage from 32% to 80%, taking the number of people served from about 36,000 to 96,000 according to a 2025 project field note (Africa Sustainability Matters).
- The Bor scheme was designed to cut annual operating expenditure by an estimated $318,000, with projected savings of $6.4 million over a 20-year design life, alongside lower carbon emissions (Africa Sustainability Matters).
- Under the 2022-2027 US Global Water Strategy, South Sudan was designated a high-priority country, with targets to provide US-supported basic water services to 100,000 people, sanitation to 75,000 people and strengthen 30 state- and county-level institutions (Africa Sustainability Matters).
What happened: the infrastructure gap behind the call for investment
The investment call is framed by a basic-services gap, not a raw-water shortage. The Nile River Basin covers 97% of South Sudan, yet national figures cited in the US government's 2023 Global Water Strategy country plan put basic water access at 41%, with a sharp urban-rural split of 70% for urban households and 34% for rural households, the report said (Africa Sustainability Matters). Rivers and lakes are common sources of water but face contamination risks from human and animal waste and from industrial activity linked to mining and oil extraction, it added (Africa Sustainability Matters).
The wider public-health consequences run through sanitation and schools. The same Global Water Strategy country plan reported that only 16% of South Sudan's population had access to basic sanitation, 45% of primary schools had safe drinking water and 17% had adequate sanitary latrines for girls and boys, according to the report (Africa Sustainability Matters).
What happened: the Bor benchmark and humanitarian installations
A solar-powered conventional water treatment project in Bor, Jonglei State, increased the number of people with access to safe drinking water from about 36,000 to 96,000, lifting service coverage from 32% to 80% according to a 2025 project field note cited in the report (Africa Sustainability Matters). The scheme combined a new treatment plant with rehabilitation and expansion of the distribution network and measures to strengthen the local water utility, the report said (Africa Sustainability Matters).
Climate exposure and operating cost were design drivers. Bor is vulnerable to severe flooding, and the infrastructure incorporated raised foundations above the highest flood levels recorded in 2020 and 2021 and a protective dyke, the report said (Africa Sustainability Matters). Solar power was estimated to cut annual operating expenditure by $318,000, with projected savings of $6.4 million over the 20-year design life, alongside lower carbon emissions, it added (Africa Sustainability Matters).
Humanitarian operators are also piloting lower-chemical surface-water systems. The International Organization for Migration and the Veolia Foundation have deployed water-treatment technology intended to reduce the amount of aluminium sulphate required by conventional surface-water treatment, with an Aquaforce 5000 installation in Pakur, Rubkona County, designed to provide treated surface water for about 5,000 people, and related systems deployed at the Wunthow border crossing in Renk County and in Malakal, the report said (Africa Sustainability Matters).
An earlier Wau example underscores the scope of a single urban upgrade. UNICEF reported that rehabilitation of the city's urban water supply system included three kilometres of additional mains pipeline, repairs to the main generator, four water kiosks and four elevated tanks, alongside training in leak detection, billing, revenue collection and utility management, with the plant drawing roughly 6,000 cubic metres of raw water a day from the Jur River before clarification and disinfection, the report said (Africa Sustainability Matters).
What it means for finance and utilities
The report frames water infrastructure as a public-finance and institutional question as much as a construction one, noting that infrastructure that cannot recover enough revenue for basic operation and maintenance can leave governments and development partners facing repeated rehabilitation costs (Africa Sustainability Matters). South Sudan was designated a high-priority country under the 2022-2027 US Global Water Strategy, with the country plan setting targets for US-supported investments to provide basic water services to 100,000 people, sanitation services to 75,000 people and strengthen 30 state- and county-level institutions, the report said (Africa Sustainability Matters).
Specification read
The headline Bor scheme lifted service to about 96,000 people from a single conventional surface-water treatment plant and distribution upgrade; per-capita demand was not given in the report, so the plant's design flow in m³/day cannot be derived from the supplied figures. Wau provides a more concrete throughput: the rehabilitated urban plant draws roughly 6,000 m³/day of raw water from the Jur River ahead of clarification and disinfection, against an urban population whose served share is not reported here. Both projects sit on the conventional surface-water train: screening, coagulation and flocculation (including aluminium sulphate use in the conventional baseline that the IOM and Veolia Foundation Aquaforce 5000 system is designed to reduce), clarification, filtration and disinfection, with the Wau scheme explicitly citing a main generator for site power. The Bor retrofit then layers two buyer-relevant changes onto that train: flood-resilient civil works — raised foundations set above the 2020 and 2021 flood levels plus a protective dyke — and a solar-driven power system that the report estimates will cut annual operating expenditure by $318,000 and deliver $6.4 million of savings over a 20-year design life. The infrastructure push described in the report bears on the intake, primary and power-supply stages of this train, rather than on biological or tertiary treatment. For procurement leads watching this market, the recognition sentence is: if your plant is a surface-water-fed municipal utility of around 6,000 m³/day with conventional coagulation-clarification-disinfection, diesel-driven pump and generator loads, and a flood- or displacement-affected service area, the Bor numbers point to where solar power, raised civil works and distribution-network rehabilitation are being bought as a single package.

FAQ
What scale of plant is South Sudan buying?
The reported Wau rehabilitation draws about 6,000 m³/day of raw water from the Jur River; the Bor scheme lifted service to about 96,000 people but did not report a design flow in m³/day, so the source does not allow a flow figure for Bor (Africa Sustainability Matters).
What operating-cost reduction is being claimed for the Bor solar-powered project?
The report cites an estimated $318,000 cut in annual operating expenditure and projected savings of $6.4 million over a 20-year design life, alongside lower carbon emissions (Africa Sustainability Matters).
What does the procurement pipeline look like for suppliers?
The report highlights new conventional treatment capacity in Bor, distribution-network rehabilitation in Wau, and humanitarian Aquaforce 5000 installations in Rubkona, Renk and Malakal, plus the 2022-2027 US Global Water Strategy targets of basic water services for 100,000 people, sanitation for 75,000 people and capacity-building in 30 state- and county-level institutions (Africa Sustainability Matters).
What flood-protection measures are being built into these plants?
The Bor project incorporates raised foundations above the highest flood levels recorded in 2020 and 2021 and a protective dyke, according to the report (Africa Sustainability Matters).
