Dewa Engineering Exercise

Scenario: A small village in a remote mountainous region needs a new water treatment system. The village has access to a nearby stream as a water source, but the water is contaminated with high levels of bacteria. The village has limited resources and electricity access.

Task:

  1. Using the principles of Dewa Engineering, propose a water treatment system for the village.
  2. Explain how your proposed system addresses the specific challenges of this location.
  3. Discuss why your system is considered sustainable and cost-effective.

Exercice Correction

Here's a possible solution:

**Proposed System:**

  • Water Source: The stream water will be collected in a sedimentation tank to allow heavier particles to settle.
  • Disinfection: A simple and low-cost ultraviolet (UV) disinfection system can be used to kill bacteria. UV systems require minimal electricity, which can be generated by solar panels.
  • Filtration: A locally sourced sand filter can be constructed to remove remaining contaminants.
  • Storage: A covered water storage tank will be built to ensure safe storage of treated water.

**Addressing Specific Challenges:**

  • Limited Resources: The system utilizes readily available materials like sand for filtration and relies on sustainable energy sources like solar power.
  • Electricity Access: The UV disinfection system is designed to operate with minimal electricity, making it suitable for the village's limited access.
  • High Levels of Bacteria: The UV disinfection system effectively kills bacteria, ensuring safe drinking water.

**Sustainability and Cost-Effectiveness:**

  • Sustainable: The system utilizes renewable energy, minimizes waste, and relies on locally sourced materials.
  • Cost-Effective: The use of low-cost technologies and minimal electricity consumption keeps operational costs low.
