Clean the ground and excavate the ground for the foundation of rainwater harvesting system.
Prepare the excavated base with a supporting layer (at least 10cm) of gravel or concrete.
Install the tanks in position.
Install the gulley in position.
Install the necessary pipework and electrical work to the system as specified in the design drawing. Reserve the needed length before backfilling to avoid re-excavation.
After installing the system, backfill the excavated space to ground level and compact it. Do not let heavy equipment and vehicle run over the ground before backfill and compaction to avoid damage to the tanks.
Rainwater Harvesting System is completed.
