Question 1

What does Specialized Logistics Solutions (SLS) do?

Specialized Logistics Solutions (SLS) is a humanitarian supply and logistics company that delivers WASH equipment, water purification products, industrial pumps, modular warehouses, and non-food items (NFIs) to UN agencies, NGOs, and government organisations. Headquartered in Juba, South Sudan, SLS manages the entire supply chain from international procurement to last-mile delivery across South Sudan, Kenya, Uganda, and the DRC.

Question 2

Where is SLS based and which countries does it serve?

Accepted Answer

SLS is headquartered in Juba, South Sudan, with operations spanning East and Central Africa. We regularly supply and deliver to South Sudan, Kenya, Uganda, and the Democratic Republic of the Congo (DRC), including hard-to-reach field locations such as Jonglei, Upper Nile, and the Greater Equatorias.

Question 3

Who are SLS's clients and distribution partners?

Accepted Answer

SLS works with UN agencies, international NGOs, and government bodies, including IOM, UNMISS, WHO, UNICEF, and the WASH Cluster. As an authorised distributor, SLS represents Butyl Products (UK), Multiquip, Aussie Pumps, and Hallgruppen, and is the sole authorised Aquatabs distributor in South Sudan.

Question 4

How much experience does SLS have?

Accepted Answer

SLS has more than 35 years of experience operating in high-risk and conflict-affected environments. Over three decades in South Sudan, the DRC, and across East Africa, the team has built the customs, transport, and partner relationships needed to maintain supply continuity even during active conflict and flooding.

Question 5

Why choose SLS over an international supplier shipping from Europe or Asia?

Accepted Answer

Unlike suppliers who ship from overseas and rely on third-party freight, SLS holds pre-positioned stock and operational staff inside South Sudan. This means faster response times, direct coordination with customs authorities such as the KRA and South Sudan customs, and hands-on technical support from delivery through to installation and maintenance.

Question 6

What WASH products does SLS supply?

Accepted Answer

SLS supplies a full range of Water, Sanitation and Hygiene (WASH) products: Aquatabs water purification tablets, P&G Purifier of Water sachets, Oxfam steel storage tanks (11 m³ to 95 m³), flexible onion and bladder tanks, water testing equipment from Hanna Instruments and Palintest, and emergency water distribution kits. Every product comes from authorised manufacturers with full certification.

Question 7

What is the difference between Aquatabs and P&G Purifier of Water?

Accepted Answer

Aquatabs are NaDCC chlorine tablets that disinfect water that is already clear, killing bacteria, viruses, and Giardia cysts in about 30 minutes. P&G Purifier of Water sachets add flocculation, removing sediment and turbidity as well as pathogens, which makes them the better choice for dirty or visibly contaminated water. In cholera responses the two are often used together: P&G for turbid water, Aquatabs for ongoing chlorination of stored water.

Question 8

What Aquatabs sizes are available and how much water do they treat?

Accepted Answer

SLS supplies Aquatabs in 67mg tablets, which treat 20 to 200 litres and are UNICEF-approved, and 8.68g tablets, which treat up to 5,000 litres each for tanks and bulk storage. All Aquatabs use NaDCC technology, have a five-year shelf life, and are available as boxes, tubs, and bulk pallets for UN and NGO procurement.

Question 9

Are SLS's water purification products approved by WHO and UNICEF?

Accepted Answer

Yes. Aquatabs 67mg tablets are UNICEF-approved and WHO-recommended for household water treatment, and P&G Purifier of Water is WHO-evaluated and EPA-registered. Oxfam steel tanks manufactured by Butyl Products meet the specification used by IFRC, ICRC, MSF, and UNICEF. Full certification and quality documentation is available for procurement records.

Question 10

What sizes of Oxfam water storage tanks does SLS supply?

Accepted Answer

SLS supplies the full range of Oxfam tanks made by Butyl Products (UK): the T11 (11 m³), T45 (45 m³), T70 (70 m³), and T95 (95 m³). The T45, T70, and T95 share the same diameter, so their galvanised steel panels are interchangeable and roof kits are universal. Each kit includes steel panels, an EPDM rubber liner, a PVC roof kit, assembly hardware, and a repair kit.

Question 11

How quickly can an Oxfam tank be installed?

Accepted Answer

A team of three people can typically erect a standard Oxfam tank in 4 to 8 hours. SLS also provides on-site technical support for tank assembly, outlet configuration, and gravity-fed distribution setup, plus training for field staff on inspection and repair.

Question 12

Does SLS supply water testing and quality-control equipment?

Accepted Answer

Yes. SLS supplies water testing instruments from Hanna Instruments and Palintest for measuring free and total chlorine, pH, turbidity, and other water-quality parameters. These tools support chlorination monitoring during cholera response and routine quality control in WASH programmes.

Question 13

What pumps does SLS supply for flooding and dewatering?

Accepted Answer

SLS supplies diesel and electric dewatering pumps, submersible pumps for borehole and well applications, and high-volume trash pumps rated to handle solids-laden floodwater. These pumps are deployed across South Sudan's flood zones for emergency dewatering and flood-control operations, including UNMISS flood response.

Question 14

Is SLS an authorised distributor for Multiquip and Aussie Pumps?

Accepted Answer

Yes. SLS is the authorised distributor for Multiquip and Aussie Pumps in East and Central Africa. As an authorised distributor, SLS supplies genuine equipment, manufacturer-backed warranties, spare parts, and in-country technical support from deployment through to maintenance.

Question 15

What flow capacities and pump sizes does SLS offer?

Accepted Answer

SLS offers pumps across a wide range of flow capacities, from compact units for small drainage tasks to high-volume trash and dewatering pumps that move thousands of litres per minute for large flood-response operations. Discharge sizes typically range from 2-inch to 6-inch and above, and our team helps match pump size, head, and flow rate to your site conditions and water type.

Question 16

Are SLS's pumps diesel-powered or electric?

Accepted Answer

SLS supplies both diesel and electric pumps. Diesel dewatering and trash pumps are ideal for remote, off-grid flood-response sites where mains power is unavailable, while electric and submersible pumps suit boreholes, wells, and fixed installations. We advise on the right power option for your fuel availability, run time, and duty cycle.

Question 17

Does SLS supply submersible pumps for boreholes and wells?

Accepted Answer

Yes. SLS supplies submersible pumps for borehole and well-water extraction, as well as for sumps and flooded excavations. These pumps support water supply in refugee settlements, community boreholes, and field installations across South Sudan, Kenya, Uganda, and the DRC.

Question 18

Does SLS provide pump spare parts, servicing, and maintenance?

Accepted Answer

Yes. As an authorised distributor for Multiquip and Aussie Pumps, SLS supplies genuine spare parts and provides servicing, maintenance, and technical support in-country. Our field teams assist with commissioning, troubleshooting, and operator training to keep pumps running through extended flood seasons.

Question 19

How quickly can SLS mobilise pumps during a flood emergency?

Accepted Answer

For flood emergencies, SLS can mobilise pumps from pre-positioned stock and prioritise urgent orders, with dispatch typically within 24 to 72 hours depending on quantity and location. SLS has supported large-scale pump deployments for UNMISS flood response across South Sudan's flood zones.

Question 20

What warehouse solutions does SLS provide?

Accepted Answer

In partnership with Hallgruppen, SLS designs and deploys modular warehouse structures for humanitarian logistics hubs, military operations, and commercial storage. Options range from rapid-deployment temporary shelters to permanent installations with insulation and solar integration, all engineered for extreme climates and remote locations.
