WASH & Water Treatment

In South Sudan camps 40-58% of households had no detectable residual in stored water. SLS explains chlorine demand, decay and how to hold FRC to the cup.

One Aquatabs 67mg NaDCC tablet treats 8-10 litres of clear water in 30 minutes. Get the full dosing table for jerrycans, tapstands and Oxfam tanks from SLS.

A buyer's checklist to verify Aquatabs are genuine, not grey-market: buy from the authorised distributor, check the batch and manufacturer, demand documentation.

Use Aquatabs for clear water and P&G Purifier of Water for turbid water. SLS compares dosing, what each removes, and how to choose for clear vs cloudy sources.

Dose Aquatabs correctly in a cholera response: one 67mg tablet per 8-10 L, 30-min contact. Lessons from 52M+ tablets SLS deployed across South Sudan in 2024-2025.

Free residual chlorine should hold 0.2-0.5 mg/L per Sphere. Learn the emergency FRC target, why doses fail in storage, and how SLS supplies Aquatabs in South Sudan.

Hold free residual chlorine source to cup in a cholera outbreak. Field doses, product choice and storage for East and Central Africa, with delivery proof.

More than 70 percent of boreholes in Jonglei State are damaged or non-functional while 304,000 displaced people strain what remains. This field guide covers FRC decay under flood conditions, when to switch from Aquatabs to P&G Purifier of Water, and how to calculate HTH drum requirements during South Sudan's active cholera outbreak.

South Sudan's 2026 cholera outbreak has crossed 102,000 cases with 535 tonnes of WASH supplies delayed — exactly when FRC monitoring matters most. This field guide covers dosing adjustments for Aquatabs 67mg and P&G Purifier of Water in turbid flood-season water, with specific targets from the GTFCC Cholera Outbreak Response Field Manual.

South Sudan's 2026 rainy season is arriving alongside record cholera burden and hundreds of thousands newly displaced. When floodwaters rise, boreholes fail, turbidity spikes, and standard chlorination stops working. This post covers the specific treatment protocols, product choices, and supply positioning decisions that keep safe water flowing when source quality is at its worst.

Burial teams in Ituri Province face one of the most critical WASH supply gaps in the 2026 Bundibugyo Ebola response. This guide covers chlorine concentrations, water storage, and PPE requirements for safe and dignified burial operations in DRC, Uganda, and South Sudan border districts.

With the Bundibugyo Ebola PHEIC declared in May 2026 and DRC's cholera burden at a 25-year high, WASH teams are managing two concurrent chlorination regimes. This post sets out dosing parameters, supply calculations, and procurement decisions field teams need right now.

Uganda's refugee settlements face record displacement from DRC, cholera cross-border risk, and the sharpest funding cuts in a decade. This field guide covers point-of-use water treatment protocols, FRC standards for trucked water, and pump procurement for WASH coordinators operating in 2026.

South Sudan's 2026 cholera outbreak has already exceeded the full 2025 record with 102,105 cases as of April. Field evidence from cluster-randomised trials in Bangladesh and Kolkata shows OCV campaigns achieve higher and more durable protection when combined with improved WASH. This post sets out the evidence and the procurement priorities for WASH teams now running OCV campaign support.

At Uganda's Nyakabande Transit Centre, WASH teams are screening Congolese refugees from an active Ebola zone under infrastructure built for standard transit throughput. With 1,205+ cases reported by 27 May 2026, the gap between standard refugee WASH and Ebola-context requirements is widening fast.

South Sudan entered the 2026 rainy season with cholera active in 16 counties and 535 tonnes of WASH supplies delayed. This field guide covers how to calculate P&G Purifier of Water sachet and Aquatabs quantities for cholera response, apply correct Sphere and WHO chlorine thresholds, and pre-position before flood-peak access collapses.

UNICEF has called DRC's cholera outbreak the worst in 25 years, with 5.3 million people needing emergency water support. This post sets out the operational decision framework for when to use P&G sachets and Aquatabs at household level versus scaling to centralized HTH chlorination — with Sphere thresholds and FRC monitoring protocols for active outbreak conditions.

The 2026 Bundibugyo Ebola PHEIC in DRC and Uganda has placed NGO procurement teams under acute pressure to source chlorine, water storage, and IPC supplies faster than international shipping timelines allow. This field guide covers volume calculations, product selection, and how pre-positioned regional stock changes procurement lead times from weeks to hours.

With Bundibugyo virus disease cases exceeding 1,000 in DRC and Uganda, South Sudan's Equatoria border facilities face urgent WASH readiness gaps. A WHO-commissioned study found only 13% of high-risk health facilities had functioning IPC structures. This post sets out the specific water supply, chlorination, and storage standards for non-ETU facilities on the preparedness pathway — and the procurement priorities to close the gap.

WHO declared a PHEIC on 16 May 2026 for the Bundibugyo Ebola outbreak in DRC and Uganda, with cases confirmed in Kampala and cross-border risk into South Sudan. ETUs require up to 400 litres of water per bed per day, with no licensed vaccine available. This field guide covers chlorine concentrations, water storage specifications, and pump and shelter requirements for rapid ETU stand-up.
