Reserve or Overhead Tank Maintenance involves periodic checks and maintenance to ensure the water storage tank is functioning correctly and safely. Here’s a list of tasks involved in the maintenance:
1. Visual Inspection :
* Check for any signs of aging, damage, or wear on the tank, its supports, and connections.
* Look for any cracks, holes, or corrosion on the tank, which can lead to water contamination or structural failure.
2. Water Quality Check :
* Check the pH level and turbidity of the stored water.
* Look for any signs of algae growth, sedimentation, or contamination.
3. Cleaning and Descale :
* Clean the tank interior, including the pipes and valves.
* Remove any mineral buildup or corrosion scale using descaling agents or chemicals.
4. Inspection of Supports and Connections:
* Check the tank supports, connections, and anchoring systems for any signs of wear, rust, or damage.
* Ensure they are securely attached to the foundation or surrounding structure.
5. Tank Lining and Coating:
* Check the integrity of the tank lining and coatings.
* Apply new coatings or linings if necessary to prevent corrosion and leaks.
6. Valve and Pipe Inspection:
* Check the condition and operation of valves, including gate valves, check valves, and butterfly valves.
* Inspect pipes for signs of corrosion, damage, or blockages.
7. Drainage and Overflow :
* Check the tank’s drainage system, including pipes, valves, and sumps.
* Ensure proper functioning of the overflow protection system.
8. Electrical and Control Systems :
* Check the condition and operation of the electrical systems, including motors, control panels, and alarm systems.
* Test the control systems to ensure accurate monitoring and control of the tank’s operation.
9. Safety Features :
* Ensure that safety features, such as overflow alarms, high-water level switches, and emergency shutdown devices, are functioning correctly.
10. Record Keeping :
* Maintain detailed records of maintenance activities, inspections, and repairs.
* Update the records to reflect any changes or modifications made during the maintenance process.
By performing these tasks, you can ensure the Reserve or Overhead Tank is functioning correctly, safely, and efficiently. Regular maintenance can help prevent accidents, reduce water contamination risks, and extend the lifespan of the tank.
