Eco 1-60 Package
Introduction
A Mono Eco 1-60 Package has been installed on your
property. With your co-operation, this unit will provide
many years of safe, reliable operation. Your unit is an
important part of the Pressure Sewer System that your
local authority has put in place to handle your sewage
and ensure a cleaner local environment. Please read the
following to understand your package and know what
you need to do to ensure optimum operation.
Purpose of the unit
To collect the waste water from your toilets (sewage),
baths and sinks (grey water) and send it under pressure
into a Pressure Sewer System. This is a network of
sewage reticulation pipelines that transports it to a
Sewage Pumping Station and eventually a Sewage
Treatment Plant. Here the solids are removed and the
water is disinfected to a degree that it can be safely
released back into our environment.
How it works
Sewage flows by gravity (downward grade) into the wet
well section of a polyethylene tank buried in your yard.
As the sewage level increases in the tank it flows up a
level control tube positioned within the tank. Air pressure
within this tube increases as the sewage level rises and
when it reaches a preset high level, a pressure switch
sends a signal to a remote mounted controller to turn on
the grinder pump unit located in the dry well section of
the tank.
The pump action draws sewage up the suction pipe and
into the grinder pump where the integral grinding wheel
(bi-hammer macerator) turns the organic solids, paper
and other soft material into a slurry of small particles.
This macerated sewage is pumped out through a
discharge pipe into the pressure sewer system. It will
continue pumping until the level falls to the preset low
level. The pressure switch will then signal the controller
to turn off the grinder pump. This is all fully automatic and
requires no input from you, apart from ensuring that the
controller is turned on.
If sewage rises to a higher level in the tank, another “high
level “ tube detects this, and an audible siren and “strobe”
warning light warns that sewage has reached the preset
high level in the tank. See "What to do if high level alarm
is on" further on in this booklet.
NOTE
Never turn off the power to the controller (control panel)
while your premises are occupied except in emergency
situations.
Ensuring access to your tank
The tank is buried in a suitable position for receiving
sewage from your premises, with the lid slightly above
ground level. There is no need to remove this lid to
access the pump unit in the dry well or the collection area
in the wet well. However access must be ensured for the
maintenance technician.
• Do not plant shrubs or trees within 2 metres of the
tank lid.
• Do not place objects or structures on or over the lid.
• Do not allow grass or other coverings to obscure the
lid and in particular, ensure that the one way air vent is
free from debris.
• Do not drive or park vehicles on the lid.
Excavating adjacent to the tank
Danger
Electrical power lines and alarm wires are buried
underground between the tank and the remote
Controller. If you need to dig in this area contact a
technician to locate the lines. See contact details
on back page.
Caution
Contact with live power lines can cause death or serious
injury. A power isolating switch on the side of
the control box must be turned off before any
excavation begins.
You also need to be aware of the inlet pipe running from
your premises to the tank and discharge pipe running
between your tank to the sewer line outside your property.
