Pump Equipment

A dewatering pump price depends on size, solids, fuel and spares, not the sticker. How flood and site teams compare hire and buy quotes, from SLS in Juba.

Solar pump quotes in Kenya turn on daily volume, pumping head and scope, not brand. SLS explains the cost drivers and how to compare bids like for like.

An Ebola unit needs 100-400 litres per patient per day and every litre leaves as wastewater. How to size pumps, drainage and holding on a contained site. SLS.

The best trash pump for flood control is a 3 to 4 inch unit moving 1,500 to 2,100 L/min. SLS shows how to choose by head, solids, fuel and service support.

A trash pump moves dirty water with solids up to 37 mm (3-inch) or 51 mm (4-inch). Where it earns its place in flood response and where it does not. From SLS.

A trash pump passes 37 mm solids at 1,500 L/min; a sump pump clears small-solids pit water. SLS explains which a flooded camp or site needs and how to buy.

Dropping one hose size can triple friction loss at the same flow. SLS shows the maths, with a worked example turning flow and run length into a hose size.

Multiquip's manuals set six service intervals for dust and silt duty pumps, before every start through every 200 hours. SLS breaks down the field schedule.

A pump's real suction lift limit is 7 to 8 metres, not the textbook 10.3 m figure. SLS on priming, air leaks and foot valves for pump fleets in East Africa.

A 6-inch diesel trash pump burns about 12 litres an hour, roughly 120 a day. SLS breaks down delivered fuel cost, convoy overhead and downtime in South Sudan.

Sphere allows 250 people per tap at 7.5 L/min, just 14.4 litres each. SLS shows the arithmetic from camp population to pump duty point, with a worked example.

Size a borehole pump on two numbers: duty flow from the tested yield and total dynamic head. SLS works a 25 m3/h South Sudan example and the oversizing traps.

Solar cuts borehole life-cycle cost ~36% vs diesel and runs fuel-free. SLS breaks down total cost of ownership, uptime and fuel-convoy risk for camp water supply.

Dewater a flooded IDP site fast: match flow, head and solids to a 3 or 4-inch trash pump, then site, prime and run it. Field playbook with in-country install.

Size borehole pumps to Sphere and UNHCR water standards, and see why solarising beats diesel on fuel cost and uptime. Supplied and commissioned in-country by SLS.

Size a trash pump for flood dewatering by flow, head and solids. Compare the Multiquip QP3TH and QP4TH for South Sudan sites, supplied and commissioned in-country.

When fuel supply disruptions shut down borehole pumps across South Sudan and DRC, safe water disappears — not from equipment failure, but from avoidable power planning gaps. This guide covers generator sizing, fuel buffer calculations, and procurement specifications for WASH field teams operating in active emergency contexts.

Generator and pump failures are the most common cause of water supply interruption at displacement sites in East Africa. This field guide covers generator sizing, dewatering pump specification, fuel planning, and procurement lead times for WASH programmes operating in South Sudan, DRC, and Uganda during the 2026 rainy season.

South Sudan's 2026 flood season opens against the worst displacement backdrop in years — 304,770 people displaced in Jonglei alone, above-normal rainfall forecast through June, and cholera gains now at risk. Pre-positioning dewatering pumps, chlorination stock, and covered storage before track access closes is the only workable strategy.

South Sudan is entering its sixth consecutive year of severe flooding, with hundreds of thousands already displaced from Jonglei state and the peak rainy season still weeks away. Across the broader region, Mozambique has recorded over 720,000 people affected by floods in 2026, and the DRC is managing its worst cholera outbreak in 25 years — a crisis driven in part by contaminated water and standing floodwater in eastern provinces.
