fields up until such time is solely the responsibility of the contractor.

A maintenance schedule shall be supplied by the contractor and approved by the Superintendent prior to
the placement of any grass seeding. This shall include a maintenance regime for establishment of grass
cover until handover, and a longer term maintenance regime to be adopted by Council after handover.

It is expected (subject to seasonal variation) that the fields will be handed over to Council 3 months from
the completion of the seeding operation.

the playing fields. Recycled water will be available at the nearby water treatment plant with design and
construction of the system from the take-off point at the plant included in this project.

The ultimate irrigation system shall include a 130,000 litre holding tank at the water treatment plant which
will deliver Class A water. The tank is sized to allow a full irrigation cycle of water. The holding tank will

takeoff point from the existing UV Filter at the treatment plant. This will include a submersible pump.

The two Senior Soccer Fields (and athletics facility) only are required to be irrigated with this contract.
However, the irrigation design is to include capacity to irrigate the junior fields and take off points to allow
future connection shall be installed.
