Unique South Australian Design:
To achieve a system which is reliable, affordable
and positive for our environment, South Australian manufacturer Ri-Industries drew on its engineering
knowledge and years of experience in producing
concrete tanks and related products.
RI-INDUSTRIES examined the common type of water treatment system,
which normally uses a concrete tank into which
a separate fibre glass or concrete baffle is fitted
and then sealed.
It was found that sealing in such a design was
not always adequate, so we designed a mono cast
model. With integrally cast baffles, our design
has been extremely reliable under tests.
No untreated effluent can be inadvertently pumped
out into the environment. This of course appeals
to environmentally conscious people, who will
also be impressed by the relatively low cost brought
about by our production methods at RI-INDUSTRIES.
physical features of interest include two aeration
chambers, 12 volt auto reset alarm, automatic sludge and skimmer returns.
provide names of master plumbers and registered drainlayers / installers in your area that
are familiar with the RI Treat Systems.
Householders must have units
serviced every three months (Check with Dept of Health ) to ensure consistent
performance. Although checks of such things as
pumps, chlorination, aeration and irrigation systems
take place at three month intervals.
Ri-Industries provides customers with a maintenance
manual which in addition to detailing maintenance
schedules, outlines the remedies whenever certain
problems arise. The Ri-Industries domestic Aerobic
System, however, will normally work continuously
without problems. Most problems of course are
encountered in extreme circumstances, like overloading
with solid wastes and intrusion of things like
rags, newspaper, oils, scraps etc.
How it works:
waste water is gravity fed into primary sewage chambers where it undergoes settlement and digestion
for 24 hours.
Settled waste water then flows into aeration
chambers where air is pumped through in fine
bubbles, providing the distribution of air and
turbulence required for effective treatment.
- Turbulence causes liquids to travel in a circular
motion through bio media which encourages biomass
growth.The biomass assimilates nutrients and
oxygen from the water, leading to a gradual
reduction of impurities as the effluent passes
through the system.
- Effluent and sludge then pass into the settlement
chamber, where the sludge settles to the bottom
before being returned to the primary chambers,
along with the scum which floats in the settlement
- Settled effluent passes through the chlorinator
into the irrigation chamber where it is held
for irrigation or other means of disposal.
- Scum and sludge are returned to the primary
chambers by a very effective return system
which keeps the system functioning for up
to three months.
- The return system enables excess sludge
to go back for storage and digestion, suppresses
odour -emitting micro-organisms, and encourages
micro-organisms to be kept at maximum population
- Problems of the treatment plant not being
used for extended period are reduced.
Treatment Tank is manufactured from 50 MPa concrete
in a mono cast process. Baffles, floor and walls
are cast in the one operation using fine tolerance
steel moulds which produce reliable wall thick nesses.

The tank capacities are:
- primary septic chambers 3,250 litres;or 4250;& 4500 litres
- aeration chambers 2,500 litres;
- settlement chamber 400 litres;
- irrigation chamber 400 litres.
Note : All tanks are water tested for 24hrs before despatch
2 RISER RINGS BEING PLACED ON RI-TREAT 300mm AND A 600mm
ALL SYSTEMS MUST BE BOUGHT 100MM ABOVE GROUND LEVEL
Unloading the tanks can be a problem ie (Power Lines Telephone Lines-Trees -Branches) House Eves other problems are Steep sloping blocks,Narrow Gates and Short Turning circles as the trucks are 10 metres long & 2.5 mtrs Wide and have unloading constraints to be adressed that is why we advise a ( SITE VISIT) on difficult sites for piece of mind !
