====== 5 m Brick Water Tower 5,000 L ======

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.

===== Functional Purpose =====

  * 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  

===== Structural Concept =====

  * 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  

===== Hydraulic Layout =====

  * Tank outlet feeds irrigation zones by gravity
  * **Minimum outlet height prevents complete emptying** to maintain tank stability
  * Isolation valve allows manual control  
  * Overflow routed to simple drainage or secondary container  
  * Optional integration with a small pump for secondary irrigation zones  

===== Safety Considerations =====

  * 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
  * Empty or near-empty tanks are more susceptible to wind forces; take care during strong wind events
  * Ensure tank straps, brackets, or anchoring to the frame are installed and checked regularly
  * Overflow and basic manual valve operation prevent flooding  

===== Manual Operation Pathways =====

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

===== Controller Integration Points =====

  * 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
  * Controller may connect to global weather forecasts when internet is available
    * High wind or storm warnings trigger alerts to the operator
    * Controller can temporarily fill or maintain tank level to prevent tipping during forecasted high winds
    * Irrigation may be suspended or modified to reduce risk to infrastructure
  * Manual bypass always available — irrigation continues even if electronics are offline  

===== Versioning Note =====

  * 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
