Rain water Harvester, Catcher Equipment with first flush diverter and leaf catcher combination kit

Rainwater Harvesting system for all Rain Catcher components required  for both domestic and commercial use.

We provide rainwater harvesting systems for domestic use as well as for schools, offices, industrial and agricultural buildings. Systems can be fully automated so they only activate when water is needed and can revert back to mains if there is no water in storage.

We supply complete systems and parts: commercial and domestic ; direct and indirect systems, downpipe filter 'FirstFlush type', tank overflow traps, suction filter kits.

Here are some Roof Catchment examples.    
The ballpark formula for calculating how much you can collect (for next to nothing) is this:

Rainfall in mm X Catchment Area in M2 X Efficiency = Water in Litres
1mm rainfall over 1 square meter catchment delivers 1 litre of water.

The .85 is because of different surfaces collect in differing amounts.
Also the first flush is dumped by our 'First Flush' system.
There will also be other losses like overflow and/or leaks.
It still works out to a huge amount of water for nothing.

Polokwane annual rainfall is listed as 495mm. A fairly dry place.
So, Just collecting off a single carport roof for example.
10 X 5 metre roof = 50M2

Then: 495 X 50 X 0.85 =
21,037.50 Litres of pure free water for the year from a single carport roof!!

A single rainshower for same catchment area but 15mm rain (common Shower):
15 X 50 X0.85 = 637.50 litres in that 20 minutes or so.

What do you pay for a litre of water at the mall? For the commercial bottlers this is known, for good reason, as FREEWATER!



The Superhead rainwater tank filter is the only unit on the South African market that combines all of the following products into one unit

Making it cost effective, neat and compact and easy to install.

  • First flush diverter
  • One way diverter. (Stops any floating debris from getting back into the system and blocking the insect screen)
  • Rotating outlet (rotates 360deg)
  • Rain head
  • A filter for the flush pipe drain
  • A leaf screen with a stainless steel mesh
  • Insect screen
  • Adjustable drainage plug
  • Removable flush cap (Allowing easy access to the inside of the flush pipe for cleaning, etc)
  • The Superhead rainwater filter has a 10 year guarantee
  • The Superhead rainwater filter is designed to automatically flush the first polluted water that comes off the roof when it rains and then diverts only clean water into your rainwater tank.
The Superhead filter is designed to prevent contaminated rainwater from entering a water tank by means of a simple, yet highly effective first-flush diverter. Although designed to avert gutter debris during the first rains, the Superhead filter ensures that any subsequent debris is also prevented from entering the tank water supply.
The filter is fitted with a grid to block large debris like leaves and insects, and can be mounted below a gutter downpipe on a wall, or attached to the tank if no supporting walls are present. The water is then channelled through a one-way funnel and vertical flush pipe that drains the polluted water. Once the flush pipe capacity has been reached, the unpolluted water is diverted to the rainwater tank by way of an overflow pipe.
An adjustable valve at the bottom of the flush pipe controls the rate at which the polluted water drains, with the length of flush pipe determining the volume of water sacrificed to reach the overflow point. A fine filter on the overflow pipe blocks any further small debris from entering the tank.
The filter is supplied as one complete system that requires only that the flush pipe be bought to accommodate the size of the roof catchment area. The 110mm PVC stores 8.5 litres/metre, with Superwall recommending that 20 litres per 100m2 of roof area needs to be flushed to produce clear water.
The Superhead Rainwater Filter system can be installed by the homeowner or any contractor, and is suitable for any rainwater collection system, whether that be in residential, commercial or rural installations.
One of the benefits of filtering rainwater in this fashion is it provides protection against debris in the water damaging any pumps, irrigations systems and appliances using the collected water.
The Superhead Rainwater Filter is supplied with a 10-year guarantee, ensuring pace of mind and durability. The product has also been treated so that it can be painted to match the colour of the building on which it is mounted.
