AOFS Reference Implementation: 5 m Brick Water Tower with 5,000 L nylon tank. Designed for simple, locally-buildable construction using available materials.

This blueprint is non-normative and intended as a practical, low-tech reference for smallholder farms, NGOs, or off-grid installations.

• Store 5,000 L of water in a tank elevated ~5 m for gravity-fed irrigation
• Provide reliable water supply without requiring specialized equipment
• Integrate optionally with AOFS Field Controllers for water level monitoring

• 5 m high brick tower in simple cross/X pattern for stability
• Supports a standard 5,000 L nylon tank (locally available)
• No specialized engineering required — buildable with local skills
• Open-top tank for inspection and filling
• Mobile Ladder or simple access for maintenance if needed

• Tank outlet feeds irrigation zones by gravity
• Isolation valve allows manual control
• Overflow routed to simple drainage or secondary container
• Optional integration with a small pump for secondary irrigation zones

• Basic stability ensured by the cross/X brick pattern
• Keep tank weight within reasonable limits (full tank ~5 tons)
• Ladder and hatch should be used carefully
• Overflow and basic manual valve operation prevent flooding

• Tank filling and irrigation can be done manually if electronics fail
• Simple paper-based logs or measurements supported

• Optional water level sensor for Field Controller logging
• AOFS control can read tank level for irrigation scheduling
• Controller can enforce a minimum water level to ensure the tank remains gravity-stable against wind forces
• Manual bypass always available — irrigation continues even if electronics are offline

• This design is so simple and locally adaptable that traditional versioning practically does not apply
• Builders may adjust dimensions, brick patterns, or tank placement according to local materials and skills
• Basic stability and functional operation should be maintained
