Contact African Tanks for sizing, pricing, and delivery to any of Eswatini’s four regions.
Buying a cost-effective galvanised water storage tank is one of the best ways to store and save water safely in Eswatini.
Each of our tanks provides a clean environment for storing either clean or grey water. African Tank Systems leads the industry in custom-designed bulk storage tanks and systems.
Water storage is a broad term covering both potable (safe to drink) and non-potable (not fit for consumption) water. Grey water is relatively clean waste water from baths, sinks, washing machines, and other kitchen appliances – not to be confused with black water, which is not reusable. Many African countries face water shortages due to drought or a lack of clean, available water. Water reservoirs keep communities in Eswatini hydrated through rain and grey water storage.
Private homes, small and large businesses, factories, and warehouses enjoy many benefits from saving water – including cost reduction and fire suppression in an emergency. With climate change, unpredictable weather patterns, and escalating utility costs, water storage solutions are essential across Eswatini.
For over a century, Eswatini’s Lugulo River has supported households and farming communities along its banks. It has provided water for domestic use, livestock, agriculture, and construction. However, this vital source has declined significantly, with reduced flow, sand build-up, and frequent dry periods making access increasingly difficult.
This situation reflects a broader national challenge. In 2026, Eswatini faces growing water pressure from climate change, aging infrastructure, and rising demand across households, agriculture, industry, and expanding towns. Government data shows that around 40% of rural communities lacked access to clean water as recently as 2023, while 70% experience drought-related hardship. At the same time, the country faces a water investment gap of approximately USD 3 billion, meaning large-scale infrastructure upgrades will take time.
As a result, water storage tanks in Eswatini have become essential. Households, farms, schools, clinics, and businesses rely on on-site storage to maintain supply where central systems cannot yet reach. The impact of drought was clearly demonstrated during the 2015–16 El Niño event, which reduced GDP by 7% and triggered a national emergency.
Since then, Eswatini has strengthened its drought resilience strategy, including launching a Drought Centre of Excellence in 2025. However, early-warning systems alone cannot ensure supply. Practical, on-site water reserves remain critical.
Urban supply is managed by the Eswatini Water Services Corporation (EWSC) in centres such as Mbabane and Manzini. In contrast, rural areas depend on boreholes, rivers, and seasonal rainfall. While major projects are underway, full coverage remains years away. Therefore, on-site galvanized steel tanks provide an immediate and reliable solution.
On-site water storage is important for rural communities in Eswatini because many areas sit outside reliable EWSC piped supply.
The Eswatini Water Services Corporation serves the country’s largest urban centres, but rural communities across Hhohho, Lubombo, and Shiselweni often depend on boreholes, rivers, streams, and rainwater.
As of 2023, 40 percent of rural communities lacked access to clean water. In addition, 70 percent of rural households face drought-related hardship every dry season.
Galvanised steel tanks provide on-site storage that does not depend on piped infrastructure. Households can fill tanks from boreholes, rainwater harvesting systems, rivers, or delivery supply, then draw on that reserve during the May-to-September dry season.
For communities like those along the Lugulo River, where seasonal flow has dropped dramatically, on-site storage is the most reliable backup available.
A rural household typically needs 20,000 to 40,000 litres for dry-season resilience, while schools, clinics, and community points may require 50,000 to 250,000 litres or more.
African Tank Systems provides portable water storage solutions ideal for areas in Eswatini with known water shortages.
Emergency water storage, including rainwater collection and rainwater harvesting tanks, supports communities across all four regions. Rainwater harvesting is currently promoted by many organisations across Eswatini and is becoming a requirement in locations where water supplies are critical.
Existing rainwater harvesting systems have already provided over 3,693 students, 137 teachers, and 256 families with the much-needed resource of water. Therefore, scalable steel tank systems can extend that impact to more schools, clinics, farms, and rural households.
In rural areas and small farming communities, rainwater helps maintain livestock, irrigate crops, and break down compost. In addition, rainwater suits rinsing fruit and vegetables directly from a garden or plantation.
Beyond agriculture, collected rainwater serves a wide range of everyday needs:
African Tank water storage systems give buyers across Eswatini an easy, cost-effective way to save water at a fraction of the price of repeated water delivery or emergency supply interruptions. This is an affordable, warranty-protected solution for either long-term or short-term water storage.
Yes. Galvanised steel tanks are safe for drinking water in Eswatini when supplied with food-grade internal coatings and potable water liners.
African Tanks applies food-grade internal coatings and liners to all potable water tanks, keeping stored water safe for drinking throughout the tank’s working life. Galvanised steel also resists corrosion that Eswatini’s hot subtropical climate and seasonal rainfall can accelerate in uncoated metals.
However, the tank stores water. It does not purify contaminated water. Therefore, rural communities relying on rainwater, boreholes, streams, or river abstraction should boil, filter, or treat water before drinking if water quality is uncertain.
Buyers should specify potable-grade requirements when ordering to confirm that the hygienic liner is included. For rural communities relying on collected rainwater or borehole supply, a well-maintained galvanised steel tank with a quality liner provides safe potable storage for 20 to 30 years.
African Tanks supplies four core tank types to buyers across Eswatini’s four regions. Each type suits different capacity requirements, site conditions, and budgets. The table below gives a fast comparison so buyers can choose the right tank type before contacting us for a quote.
| Tank type | Capacity range | Best used for | Why it suits Eswatini |
| Steel tanks | 50,000 – 5,000,000+ L | Large irrigation schemes, sugar estates, industrial supply | Handles the high-volume demand of Eswatini’s sugarcane estates, which consume 67% of the country’s irrigated water |
| Galvanised tanks | 10,000 – 1,000,000 L | Households, schools, clinics, smallholder farms | Zinc coating resists Eswatini’s hot subtropical climate; affordable for rural community and subsistence farm needs |
| Bolted tanks | 100,000 – 10,000,000+ L | Remote Hhohho and Shiselweni sites, SWSC infrastructure | Flat-pack panels assemble on-site in hilly terrain across all four regions without heavy machinery |
| Sectional tanks | 10,000 – 500,000 L | Urban buildings, factories in Matsapha industrial zone, hotels | Space-efficient for industrial and commercial building integration in the Manzini-Matsapha corridor |
Steel tanks deliver the highest capacity range in the African Tanks range, scaling from 50,000 litres to well over 5,000,000 litres for large agricultural, industrial, and community infrastructure projects. In Eswatini, the sugar industry is the dominant user – sugarcane production accounts for 67 percent of the country’s total irrigated water consumption, and large estate storage tanks keep irrigation reliable through dry seasons and drought years. Beyond sugar, steel tanks serve EWSC-supplementary community infrastructure and large industrial sites along the Matsapha corridor.
Galvanised tanks combine affordability and durability in a format well-suited to Eswatini’s subtropical climate. The zinc coating protects the steel against corrosion under sustained heat and seasonal rainfall across all four regions. In addition, galvanised tanks are the practical choice for smallholder farmers growing maize, sorghum, and beans across Shiselweni and Lubombo, rural schools and clinics in Hhohho and Manzini, households in areas beyond the EWSC supply network, and community rainwater harvesting projects.
Bolted steel tanks are the best option for remote sites across Hhohho’s hilly terrain and rural Shiselweni and Lubombo.
They ship as flat-pack modular panels from South Africa and assemble on-site with basic tools – no heavy machinery or crane access required. Individual panels transport easily by standard truck or bakkie to sites on secondary roads across Eswatini’s varied landscape.
These tanks scale from 100,000 litres to over 10,000,000 litres, making them suitable for both village water points serving a few hundred households and large-scale government or NGO water infrastructure projects.
Bolted tanks are the most versatile solution for large-capacity and remote installations in Eswatini. Each unit ships as modular flat-pack panels from South Africa, travelling by road across the border and assembling on-site in any of Eswatini’s four regions. That flexibility makes bolted tanks the first choice for government water infrastructure projects – including the major Shiselweni Water Supply and Sanitation Project – NGO water access programmes, and any large-scale installation in rural terrain where crane access is limited.
Sectional tanks work well in urban and industrial settings where space is constrained. In the Matsapha industrial zone, Manzini commercial districts, Mbabane city, and hospitality sites across Eswatini’s highlands, buyers use sectional tanks as backup supply during EWSC interruptions and as primary storage for commercial operations. Space-efficient panel construction means larger capacities fit into confined industrial and commercial building footprints.
We stock and manufacture multiple sizes, designs, capacities, and types of steel and galvanised tanks for sale across Eswatini. Capacity conversions to gallons are available on request.
Large capacity options include:
Larger custom capacities are available on request for municipal, agricultural, industrial, and NGO projects.
Contact African Tanks for further information on water tank dimensions, available price lists, and current special offers for delivery to Eswatini.
Available designs include rectangular, circular, square, elevated, and custom or customised configurations in galvanised and steel construction. Water tanks can be customised to suit your specific needs and connect to various types of water collection systems, including rainwater harvesting, boreholes, municipal inlets, and river abstraction systems.
A household of four to six people in Eswatini typically needs between 10,000 and 30,000 litres of on-site storage for normal backup use.
A rural household that relies on rainwater, boreholes, or seasonal streams may need 20,000 to 40,000 litres to cover the May-to-September dry season for drinking, cooking, bathing, and basic household use. In drought years, that same household may benefit from 40,000 to 60,000 litres.
Rural households in Shiselweni and Lubombo should size toward the upper end of the range because 70 percent of rural households face drought-related hardship. Meanwhile, households in Manzini or Mbabane with intermittent EWSC supply usually need backup rather than full-season storage, typically 5,000 to 15,000 litres.
African Tanks can advise on the right capacity for your region, household size, water source, and dry-season risk.
Different sectors across Eswatini’s four regions face different capacity needs and storage pressures. The table below helps buyers identify the right tank size range and understand why reliable on-site storage matters for their particular operation.
| Sector | Typical capacity needed | Why storage is critical here |
| Sugarcane and commercial agriculture | 500,000 – 10,000,000+ L | Sugarcane accounts for 67% of Eswatini’s irrigated water use; large estate storage stabilises supply through the dry season and drought years |
| Smallholder and subsistence farming (maize, sorghum) | 10,000 – 500,000 L | 70% of rural households face drought-related hardship; on-farm storage helps smallholders in Shiselweni and Lubombo bridge dry-season gaps |
| Municipal and peri-urban community supply | 50,000 – 1,000,000+ L | EWSC serves major urban centres but 40% of rural communities lacked clean water access as recently as 2023; on-site tanks fill the gap |
| Industrial water supply (Matsapha industrial zone) | 100,000 – 2,000,000+ L | Surface water quality in the Matsapha catchment is affected by industrial discharge; on-site storage with proper spec protects industrial operations |
| Rainwater harvesting (rural communities) | 10,000 – 250,000 L | Rural communities in all four regions – Hhohho, Manzini, Lubombo, Shiselweni – rely on captured rainfall as dry-season backup |
| Schools and healthcare facilities | 10,000 – 100,000 L | Rainwater harvesting systems have already provided 3,693 students, 137 teachers, and 256 families with water access – steel tanks scale that reach |
| Construction and project sites | 5,000 – 250,000 L | Large water infrastructure projects including the E1.2bn Shiselweni Water Supply Project and Manzini Region project need site water supply |

African Tanks builds galvanised and bolted steel water storage tanks that outlast plastic alternatives by decades.
For buyers in Eswatini, where drought years consume significant national resources and remote rural sites make replacement difficult and expensive, durability is one of the most important purchasing criteria.
The table below summarises the key benefits and what they mean for buyers across Eswatini’s four regions.
| Benefit | What it means for buyers in Eswatini |
| Warranty protection | Every tank carries written warranty cover – vital for rural Hhohho and Shiselweni installations far from the nearest supplier |
| Galvanised steel construction | Zinc coating resists Eswatini’s hot subtropical climate and the corrosion that heat and seasonal rainfall accelerate in uncoated metals |
| Hygienic potable storage | Food-grade coatings and liners keep drinking water safe – critical where 40% of rural communities lacked clean water access as recently as 2023 |
| Modular panel design | Flat-pack bolted panels ship from South Africa and assemble anywhere across Eswatini’s hilly terrain without heavy equipment |
| Custom capacities | Tanks scale from 10,000 L household backup to 10,000,000+ L commercial irrigation supply – any scale, any sector |
| Affordable long-term solution | Steel outlasts plastic by 20 to 30 years – the 2015-16 El Nino drought consumed 7% of Eswatini’s GDP; long-lasting storage is an investment in resilience |
| After-sales support | African Tanks provides installation guidance and remote technical support after delivery – important for rural sites in Lubombo and southern Shiselweni |
Choosing the right water storage tank in Eswatini requires buyers to think about the country’s specific conditions – drought frequency, hilly terrain, a limited EWSC coverage footprint, and a growing industrial water quality challenge at Matsapha. The considerations below apply across all four regions and reflect 2026 buying realities.
| Consideration | What to think about |
| Daily water demand | Base tank size on peak-use days – dry-season farm demand, household peak use, and drought years all push consumption above daily averages |
| Water source type | River draw from the Lusutfu, Komati, or Mbuluzi; borehole; EWSC piped supply; or rainwater harvesting – each affects sizing and spec differently |
| Potable vs non-potable use | Potable storage requires certified food-grade coatings; sugarcane irrigation and industrial cooling use does not |
| Site location and terrain | Hilly terrain across Hhohho and Manzini regions suits bolted tanks assembled in place; flat Lubombo sites suit complete unit delivery |
| Drought duration and frequency | The 2015-16 drought cost Eswatini 7% of GDP; buyers should size for at least a full dry season (May to September) plus a drought reserve buffer |
| Proximity to EWSC supply | Rural communities in Shiselweni and Lubombo with no EWSC coverage need full-season storage; urban buyers in Mbabane and Manzini need backup only |
| Industrial water quality (Matsapha) | Buyers near the Matsapha catchment should use enclosed steel tanks with quality liners to protect stored water from industrial catchment contamination |
| Budget vs lifespan | Steel outlasts plastic by 20 to 30 years – factor total cost over the tank’s working life, not just upfront price |
| Expansion plans | Oversizing by 20% now costs less than adding a second tank later – especially relevant for remote rural sites where delivery logistics add cost |
Choosing the right tank size starts with understanding your peak daily demand, not your average consumption.
In Eswatini, the dry season runs from May to September. In addition, drought years can stretch water shortfalls well beyond the normal dry season. Therefore, buyers should size for the longest realistic gap between reliable water supply events and add a drought buffer on top.
For a household of four to six people relying on rainwater or a seasonal stream in Shiselweni or Lubombo, a tank in the range of 15,000 to 30,000 litres covers drinking, cooking, and basic hygiene through a normal dry season. In a drought year, that same household benefits from a tank closer to 40,000 to 50,000 litres.
Smallholder farmers growing maize and sorghum across Lubombo and Shiselweni typically need between 50,000 and 250,000 litres to irrigate through the dry season when rivers and groundwater levels drop.
Commercial sugar estates and large irrigation schemes along the Lusutfu, Komati, and Mbuluzi river systems need storage in the range of 500,000 to 10,000,000+ litres to buffer seasonal flow variation and drought-year reductions.
At that scale, bolted steel panels are the most practical solution. They ship from South Africa across the border and assemble on-site at the estate without crane access.
Industrial buyers in the Matsapha corridor typically need between 100,000 and 2,000,000 litres depending on production volume and water intensity.
In all cases, oversizing by 20 percent at purchase is far cheaper than sourcing and delivering a second tank later. Eswatini’s land-locked geography means an additional cross-border delivery adds meaningful cost and lead time.

African Tanks manufactures all tanks in South Africa and delivers them to buyers across Eswatini by road.
Eswatini’s land-locked position and shared borders with South Africa and Mozambique make cross-border road delivery efficient. Tanks reach Mbabane, Manzini, Nhlangano, Siteki, Matsapha, and sites across all four regions directly from our South African manufacturing facility.
Complete steel units deliver by flatbed truck. Meanwhile, bolted and sectional tanks ship as flat-pack modular panels that teams assemble on-site without heavy machinery. This matters greatly for sites on Eswatini’s hilly terrain in Hhohho and Manzini.
Once components reach the site, assembly follows step-by-step installation guidance that African Tanks provides with every order. After delivery, our team remains available for remote technical support and after-sales assistance throughout the tank’s working life.
Buyers with sites on secondary roads or in areas with limited vehicle access should share location details when ordering so African Tanks can advise on the optimal panel configuration and delivery approach.

Bolted and sectional tanks ship as flat-pack panels for easier delivery to remote and hilly locations.
Contact African Tanks directly to discuss capacity, delivery timeline, and pricing for your Eswatini location.
The cost of a water storage tank in Eswatini depends on capacity, tank type, and delivery distance from the South Africa manufacturing facility.
Galvanised tanks in the 10,000 to 100,000 litre range suit most household and smallholder farm budgets. Bolted steel tanks for community and estate irrigation carry higher upfront costs but a significantly lower total cost over a 20 to 30-year working life compared to plastic.
Contact African Tanks for a current price list and capacity options tailored to your region and sector.
Farm tank sizing in Eswatini depends on crop type, irrigated area, and how long the dry season and drought years last at your site.
Smallholder maize and sorghum farmers in Shiselweni and Lubombo typically need 50,000 to 250,000 litres to irrigate through the May-to-September dry season.
Commercial sugar estates need 500,000 litres and above, with large operations requiring multi-million litre installations. African Tanks can advise on the right capacity for your farm, crop type, and region.
Yes. African Tanks applies food-grade internal coatings and liners to all potable water tanks, keeping stored water safe for drinking throughout the tank’s working life. Galvanised steel resists the corrosion that Eswatini’s subtropical heat and seasonal rainfall accelerate in uncoated metals.
Buyers should specify potable-grade specification when ordering – African Tanks includes hygienic liners as standard on all drinking water tank orders.
For rural communities relying on rainwater harvesting, a well-maintained galvanised steel tank with a quality liner provides safe potable storage for 20 to 30 years.
A well-maintained galvanised or bolted steel water tank from African Tanks lasts 20 to 30 years in Eswatini’s hot subtropical climate.
The zinc coating applied through hot-dip galvanising protects the underlying steel against corrosion under sustained heat and seasonal rainfall. By comparison, plastic tanks typically degrade in 7 to 15 years under Eswatini’s high-UV, high-temperature conditions.
For buyers in remote rural regions where replacement is logistically inconvenient and costly, steel’s longer working life makes it the only sensible long-term choice.
Galvanised water tanks consist of steel panels or shells coated with a layer of zinc through a hot-dip galvanising process.
The zinc coating creates a physical barrier between the steel and the surrounding environment, preventing rust and corrosion.
Internal food-grade liners add a second layer of protection for potable water storage. In Eswatini’s subtropical conditions – where heat, humidity, and seasonal rainfall accelerate corrosion in unprotected metals – galvanised steel provides far longer working life than uncoated alternatives.
Yes. African Tanks manufactures large-capacity steel and bolted tanks specifically for commercial agriculture and irrigation at scale.
Sugarcane estates across Eswatini – where the sugar industry accounts for 67 percent of the country’s irrigated water use – use bolted steel tanks from 500,000 to over 5,000,000 litres to stabilise irrigation supply through dry seasons and drought years.
Contact African Tanks for product specifications, technical guidance, and pricing for commercial agricultural installations.
Yes. African Tanks delivers water storage tanks to rural areas in Shiselweni and Lubombo, as well as Hhohho and Manzini.
Remote delivery is possible because bolted tank systems ship as flat-pack modular panels. These panels can travel by standard truck and can often be moved by bakkie or smaller vehicles where large trucks cannot reach.
This is important in rural Eswatini, where hilly terrain, secondary roads, and limited access can make complete-unit delivery difficult. Bolted tanks solve that challenge by allowing on-site assembly using basic tools.
Typical rural applications include household water storage, school and clinic supply, livestock watering, smallholder irrigation, and community water points ranging from 50,000 to 500,000 litres or more.
EWSC piped supply is centralised water distributed by the Eswatini Water Services Corporation, while on-site tank storage is water kept at your property for direct use when needed.
EWSC manages piped water in major urban centres such as Mbabane, Manzini, and Matsapha. However, many rural areas in Hhohho, Lubombo, and Shiselweni rely on boreholes, rivers, streams, and rainwater instead.
Even inside EWSC coverage areas, supply can be affected by drought, peak demand, maintenance, or infrastructure constraints. On-site tanks allow buyers to store water when supply is available and use it when supply is interrupted.
For rural buyers, on-site storage is often the only reliable way to guarantee year-round access. For urban buyers, it provides backup continuity for households, factories, hotels, schools, and healthcare facilities.
You can protect your water tank from Eswatini’s dry-season conditions by choosing galvanised steel, sealing fittings properly, inspecting the tank annually, and positioning it on a suitable base.
Dry-season conditions in Eswatini include heat, UV exposure, low rainfall, and temperature swings. These factors degrade plastic tanks faster, but galvanised steel tanks resist UV damage and maintain structural strength for 20 to 30 years.
Buyers should inspect the zinc coating, fittings, roof, inlet screens, outlet valves, and internal liner once a year. In addition, tanks should be installed on a stable concrete base or prepared foundation to prevent movement and moisture damage from the ground.
Where practical, buyers can reduce evaporation by keeping lids, vents, and access points properly sealed. African Tanks provides maintenance guidance with every installation and remote support after delivery.
You can get a price for a water storage tank in Eswatini by contacting African Tanks with your required capacity, location, intended use, and site access details.
To prepare an accurate quote, African Tanks needs your required litres, region, nearest town, water source, potable or non-potable use, and whether the site can receive a complete tank or needs flat-pack modular panels.
For example, a household in Mbabane may need a 10,000 to 30,000 litre galvanised tank, while a rural project in Shiselweni may need a 50,000 to 250,000 litre bolted system. Industrial or agricultural buyers may need 500,000 litres to more than 5,000,000 litres.
For remote sites, sharing GPS coordinates or district details helps African Tanks recommend the best panel configuration and delivery route.
On-site water storage in Eswatini is critically important in 2026 because drought risk, rural water gaps, and infrastructure delays continue to affect households, farms, and businesses.
On-site water storage means keeping water in a tank at your property, farm, school, clinic, or project site so it is available when central supply, rainfall, rivers, or boreholes are unreliable.
Eswatini’s water investment gap stands at an estimated USD 3 billion, meaning centralised infrastructure will take years to reach every community. As recently as 2023, 40 percent of rural communities lacked reliable clean water access. In addition, the 2015-16 drought cost the country 7 percent of GDP and triggered a national emergency.
Although Eswatini has strengthened drought resilience planning and launched a Drought Centre of Excellence in September 2025, planning systems cannot replace physical water reserves. Therefore, galvanised and bolted steel tanks provide practical resilience for households, farms, communities, and industries.
A rural household of four to six people in Shiselweni typically needs 20,000 to 40,000 litres of on-site water storage for the May-to-September dry season.
A dry-season household tank stores water for drinking, cooking, washing, sanitation, and basic hygiene when rainfall is limited or seasonal streams run low. In Shiselweni, this is especially important because many rural households face drought-related hardship.
For normal dry-season conditions, 20,000 to 40,000 litres gives a household practical reserve capacity. However, in a drought year similar to 2015-16, the same household may benefit from 40,000 to 60,000 litres.
As a result, rural households should size for their daily water use, household size, water source reliability, and a 20 percent drought buffer.
Yes. Steel tanks are better than plastic for long-term water security in Eswatini because they last longer, resist UV damage, and perform better at large capacities.
Steel water tanks typically last 20 to 30 years. Plastic tanks usually last 7 to 15 years under Eswatini’s high-UV and high-temperature conditions.
In addition, steel tanks provide stronger structural stability during drought-driven temperature extremes. They are also better suited to large-scale storage for farms, schools, clinics, industries, and community water systems.
For buyers comparing total lifetime cost, galvanised steel usually delivers a lower cost per year of service. In remote areas of Lubombo and Shiselweni, where replacement is expensive and logistically difficult, that durability advantage is especially valuable.
A galvanised water tank in Eswatini typically lasts 20 to 30 years when installed and maintained correctly.
A galvanised tank is protected by a zinc coating that prevents corrosion. This is important in Eswatini’s hot subtropical climate, where heat, seasonal rainfall, humidity, and dry-season exposure can shorten the life of weaker materials.
Plastic tanks typically degrade in 7 to 15 years due to UV exposure, heat, and brittleness. By contrast, galvanised steel maintains its structural integrity for much longer.
To maximise lifespan, install the tank on a stable base, inspect coatings and fittings annually, and use potable-grade liners where drinking water is stored. For rural buyers, the longer service life reduces the need for costly repeat deliveries from South Africa.
Water storage tanks support farming and food security in Eswatini by storing water for irrigation during dry months and drought years.
A farm water tank allows farmers to collect and hold water from rain, rivers, boreholes, or irrigation systems, then use it when natural supply drops. This improves crop survival and protects farm income.
The sugar industry uses large-capacity steel tanks to stabilise irrigation supply because sugarcane accounts for 67 percent of Eswatini’s irrigated water use. Smallholder farmers in Shiselweni and Lubombo also use galvanised tanks to store wet-season rainfall for maize, sorghum, beans, livestock, and household food production.
Typical smallholder storage ranges from 50,000 to 250,000 litres, while sugar estates and commercial farms may need 500,000 to more than 10,000,000 litres. As a result, water tanks directly support irrigation reliability, food production, and rural resilience.
