In November 2024, Xinguangzheng delivered a 15-meter-high steel water tower to Yamoussoukro, Côte d’Ivoire. The tower has a 50,000-liter capacity and was built for a facility producing palm oil, palm kernels, and corn. It provides reliable water storage for irrigation and processing. The design uses low-cost galvanized steel to handle the region’s tropical climate. This ensures durability against humidity, heavy rains, and corrosion—common issues in West Africa.
Customer Demand
Our client is an agribusiness firm near Yamoussoukro in central Côte d’Ivoire. They specialize in palm oil extraction, palm kernel processing, and corn milling. Regional demand for biofuels and food staples has driven their production growth. To support this, they needed a cost-effective water tower for irrigation, kernel washing, and milling.
Their ground-level tanks were inefficient. Seasonal flooding often contaminated the water. The tanks also couldn’t meet the scale of their operations, which process over 5,000 tons of raw materials each year. The humid climate—over 1,500mm of annual rainfall, temperatures between 22°C and 32°C, and harmattan dust—added challenges like rust and instability.
After consultations, Xinguangzheng proposed a custom steel water tower:
- Capacity and elevation: A 50,000-liter tank elevated 15 meters for gravity-fed water distribution. This would support irrigation for 20 hectares and processing lines.
- Budget constraints: The total cost was capped at 5,500,000 XOF (about 8,500 USD). Affordable materials were used to suit small-scale agribusiness needs.
- Climate resilience: The design resists corrosion and includes ventilation to reduce condensation. This cuts maintenance costs by 30-40%.
- Modularity: The tower integrates easily with existing farm systems. It allows for future expansions, like adding tanks or solar pumps.
Solutions
Xinguangzheng designed the water tower with galvanized steel. The design fits Côte d’Ivoire’s agricultural needs. Prefabricated components were made in partnered facilities. These met ISO 9001 and local Ivorian standards, including CNPS safety rules. This approach ensured stability, cost efficiency, and minimal on-site labor.
Core Specifications
- Dimensions and layout: The tower is 15 meters high with a 3m x 3m base. It supports a cylindrical tank with a 50,000-liter capacity (4m diameter, 4m height). The elevation ensures good pressure for drip irrigation.
Structural components:
- Frame: Made of Q235B galvanized steel beams and supports. It has a load capacity of 60 kN/m² and handles light wind loads and tropical humidity.
- Tank and cladding: Built with 1.2mm hot-dip galvanized steel sheets. These have an anti-corrosion coating (zinc layer 275g/m²). The tank works well in temperatures between 20°C and 35°C and resists UV damage.
- Foundation: A reinforced concrete pad system designed for soft savanna soils. Anti-settling anchors keep it stable during wet seasons.
Custom functions:
- Overflow and access: A built-in ladder and overflow pipe allow safe maintenance and water level checks.
- Filtration integration: The system is ready for basic sediment filters to keep water clean for kernel processing.
- Emergency reserve: A 500-liter lower compartment provides backup water during peak corn milling seasons.
Implementation Process
The project was completed in three phases over four months. Components were prefabricated in China, shipped to Abidjan port, and transported inland for assembly.
- Prefabrication phase (1 month): Components were fabricated with precision. Galvanization tests were done under simulated humid conditions to ensure durability.
- Site preparation (10 days): Soil testing and foundation pouring were done on the client’s farm. Local labor was used to save costs.
- Assembly and testing (2 months): The structure was bolt-assembled to avoid welding costs. Tank filling and pressure tests followed. Anti-corrosion enhancements, which used 15% of the budget, were added to prevent rust during rainy seasons.
Results
Since November 2024, the water tower has delivered excellent results:
- Operational efficiency: Elevated storage improved irrigation flow. Crop yields increased by 25% in palm and corn fields. Water wastage during processing also dropped.
- Cost benefits: The total project cost of 5,200,000 XOF (about 8,000 USD) came in 10% under budget. This enabled a quick return on investment through better production.
- Resilience: The tower endured its first rainy season without leaks. The galvanized layers ensure a lifespan of over 30 years with minimal maintenance.
- Sustainability: The gravity-fed system reduced energy use by 35% compared to pumps. This aligns with Côte d’Ivoire’s green agriculture goals.
