Frequently asked questions

FAQs for Micro Hydro Maintenance
and Servicing

How often should a micro hydro system be serviced?

Routine maintenance should be carried out at least once a year, with more frequent checks (e.g. monthly or quarterly) depending on the site’s conditions and system size. Remote monitoring systems can help flag issues early, but scheduled inspections are essential for long-term reliability.

A typical service involves:

  • Inspecting and cleaning the intake and screens
  • Checking the penstock for leaks or blockages
  • Examining the turbine and generator for wear, alignment, and lubrication
  • Testing electrical connections and control systems
  • Verifying voltage and frequency outputs
  • Checking bearings, seals, and overall structural integrity

Look out for:

  • Reduced power output
  • Unusual noises or vibrations from the turbine
  • Overheating of components
  • Alarms from monitoring systems
  • Visible debris or blockages at the intake
  • Early attention can prevent bigger, costlier problems.

Yes, basic tasks like clearing debris from screens, visual checks for leaks, and monitoring system performance can often be done by the owner. However, technical inspections, electrical servicing, and mechanical alignments should be carried out by qualified technicians to ensure safety and compliance.

  • Schedule regular professional servicing
  • Use remote monitoring for real-time alerts
  • Keep intakes and screens clean
  • Perform minor checks after storms or heavy rain
  • Maintain accurate service records
  • Proper care extends equipment life and ensures consistent energy output.
