Standard reservoirs are not supplied with a roof or cover.

ADVANTAGES OF A ROOF OR COVER

  • Prevent dirt and leaves entering the reservoir.
  • Reduce evaporation.
  • Reduce sunlight to help prevent growth of algae.
  • Safety – access more difficult for swimming.
  • Prevents animal access.

 

CORRUGATED STEEL ROOFS:

0.47mm thick zincalume corrugated sheets are used for a lightweight covering. 

A safety edge is placed over the ends of the roof to prevent injury.

There is a 400mm manhole fitted to the roof.

NB there is a need to use light weight materials that can be supported by the corrugated steel wall. As a result the roof is not designed to be walked on by humans.
