Lecture Notes on Home Water Management and Cistern Tanks

Introduction

• Discussion on the renovation of a second floor due to the need for more space.
• Recent experience of water shortage in the subdivision due to a heat wave.
• Strategies for ensuring minimal disruption in water supply.

Importance of Water and Electricity

• Electricity and water are the most important utilities in a home.
• Importance of having backup solutions like generators and batteries for electricity.
• Introduction of the concept of a 'water generator' or cistern tank for water.

Cistern Tank

What is a Cistern Tank?

• A tank used to store water as a reserve in case of main water supply cut-off.
• Functions as an underground reservoir to ensure continuous water availability.

Comparison with Rainwater Tanks

• Cistern tanks are different from rainwater tanks.
  • Rainwater tanks collect water from rooftops for uses like watering plants.
  • Cistern tanks provide a consistent supply of fresh water regardless of rain.

Benefits of a Cistern Tank

• Provides water during droughts or main supply issues.
• Typically designed to provide 3-days to a week's worth of reserve water.
• Can be filled by water truck deliveries if needed.
• Offers flexibility with different designs—underground or above-ground versions available.

Design Considerations

• Underground tanks can support the weight of vehicles, are aesthetically pleasing.
• Consider the size based on family water consumption; larger tanks offer more reserve capacity.
• Design should include a sealed lid to prevent dirt and animals from entering.

Maintenance and Safety

• Regular cleaning and maintenance is crucial, ideally every 6-12 months.
• Water should be tested regularly for safety.
• Use of chlorine in small doses as a precaution against bacteria.
• Additional filtering systems ensure water safety for drinking.

Operation Mechanism

Float Switch

• A device indicating water level in the cistern tank.
• Automatically controls the filling of the tank based on water level.

Cost and Installation

• Costs vary depending on size and installation specifics (e.g., underground vs. above-ground).
• Larger, more robust designs will be more expensive.

Conclusion

• Cistern tanks are a valuable investment for ensuring consistent water supply.
• Especially beneficial in areas with inconsistent water availability.
• It's an often-overlooked yet crucial component of home comfort and utility management.
