|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
|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!
|SUPERHEAD RAINWATER TANK FILTER -
OUT OF STOCK
|The Superhead rainwater tank filter is the only unit on
the South African market that combines all of the following products into one
Making it cost effective, neat and compact and easy to
- 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
- 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.
