Installation Process

Step 1 – Establish Rainwater Harvesting Capacity

  • Determine roof area.
  • Determine average rainfall per week from Mauritius Bureau of Meteorology
  • Calculate tank capacity by multiplying roof area and average rainfall per week

For example, a roof area of 100 m2 with an average rainfall of 25 mm yields 2500 lts (100 m2 x 25 mm = 2,500L).  Required tank capacity = 2,500L

Step 2 – Based on the capacity of storage, you can select from the different models available.

  • Column Type Rainwater Tank – 350 Litres to 500 Litres
  • Integrated Filter Type Rainwater Tank: 2500 L to 9000 L (Patented model)
  • Slim Rainwater Tank 1200L
  • Underground Rainwater Tank – 4700 Litres

Step 3 – Selection of accessories for Rainwater Harvesting

  • Water pump
  • Level Indicator

Step 4 – Preparation of Site to accommodate Rainwater Tank.

  • Ensure the tank is placed on a solid and levelled concrete base.
  • The guttering on your roof is also a key component in your rain harvesting system and will need to be cleared of any leaves or debris. Sometimes guttering may also need to be adjusted to direct the water to the corner of your house where the tank is installed.
  • Tank overflows must be designed to ensure storm water does not pond under the concrete base, the building floors or flood around foundations and footings of buildings.

Step 5 – Distribution of the rainwater

  • Diverts first 60 litres of rainfall to ensure cleaner supply.
  • Select a pump and filtration system to distribute water for use inside or outside the home.
  • Connect to your washing machine, toilets or outside gardening tap.

Installation of Water Tanks:

  • Water Tanks should NOT be installed on:

(i) Rocky and Uneven Surfaces

(ii) Block and Metal Frames.

  • Best installation practice is to place your tank on a flat, smooth and even surface.

  • Outlet should be well supported to avoid the risk of leakage and damage to the water tank at outlet.

NOTE:  These Water Tanks are not designed to be installed as underground Rain Water Tanks except the model of underground of capacity 4700L.
