Refer Notes on back page.
The Polymer Pump Well should be located in areas not exposed to any vehicle or regular pedestrian
traffic. It should be installed in an area set aside for garden use, and finally covered with bark or garden
mulch after installation is complete. Where the Pump Well is in a high water table area extra anchorage
may be required. See "ANCHORAGE".

PREPARATION
Ensure that –
appropriate approvals have been given by local authorities.
appropriately qualified persons, including electricians and plumbers, are employed to install and connect
the pumpwell.
We recommend that all holes cut in the pumpwell are made leak proof using rubber o-rings (provided), rubber
seals or bulk head fittings.
The pumpwell has three additional flat vertical areas that allow inlets to be cut into the pumpwell. These should
be sealed with an appropriate rubber seal or silicon.
SAFETY
Take care when working around excavated holes.
Deep holes can be considered confined
spaces. Consult with local/state laws and
make provisions as appropriate.
An empty pumpwell weights in excess of
70kgs. Take appropriate precautions when
manually handling the pumpwell.
Always use lifting holes to lower the pump
well into the excavated hole
SITE ASSESSMENT
Take note of the invert heights of the available inlets
into the pumpwell and ensure that the incoming
100mm drainpipe is appropriately supported and
allows for wastewater to flow directly into the
pumpwell.
Site MUST be away from areas susceptible to all
vehicular and foot traffic.
THE EXCAVATION
a) Prepare excavation greater than 1500mm
diameter up to 1900mm deep (Deeper holes may be
used when a riser is fitted). Sides and bottom should
be free from all intruding roots, stones, or other
matter.
b) Determine which of the inlet Connection Ports is to
be used. This will depend on the depth of the pipe
from the wastewater source at the point where it
meets the Pump Well.
c) Trench excavation should be widened for
vent connection (see below)
pumped water discharge
electrical connections
d) Line the bottom of the hole with 50mm of sand or
3mm pea gravel
PUMPWELL PREPARATION
a) Cut out the Inlet opening selected using an
appropriately sized hole saw.
b) Venting of the upstream pipe is usually adequate
for most installations. Where needed, a vent port to
suit the required pipe size may be cut in the side of
the pumpwell and may be secured using a bulk head
fitting.
c) Cut hole to accept selected pump discharge hose
or pipe fitting. This hole is normally in any vertical
face of the pumpwell. The size of the hole will be
dependent on the diameter of the discharge pipe
b) Cut the hole to accept the glands selected for the
electrical cable and flexible conduit. This should be
close to the side of the Pump Well to minimise the
exposed electrical conduit.

POSITIONING AND FITTING OUT THE PUMP WELL
a) Remove the access cover and clear all cuttings from the interior of the pumpwell
b) Fit vent and discharge attachments as required
c) Using the lifting holes, carefully lower the pump well into the excavated hole, seating the base of the pump well
into the sand bed.
d) Connect the 100mm drain pipe to the pump well.
e) Fit out pump as required.
f) Fit access cover ensuring all screws are secure.
BACKFILL
a) Backfill around the pump well, compacting as you go, ensuring that the pump well remains level and the pipe
work is not damaged.
b) In areas that are effected by high water tables, the first 500mm must be backfilled using a concrete.
d) Use excess soil to build a bund above the pumpwell to divert stormwater away from the installation.
FURTHER RECOMMENDATIONS FOR INSTALLATION
Where the required depth to the pipe invert makes the Pump Well lower than normal, a Riser can extend the
access opening to surface level. This is EVERHARD Ribstruct 600mm pipe fitted with a top collar, secured by
screws, which accepts the standard Access Cover. The Pump Well access rim should be cut off with a saw,
leaving a plain upstand of about 20mm. The Ribstruct is trimmed to the required length, leaving a rib-flange at the
lower end. Apply the black butyl joint tape to the rim of the open access hole and push the firmly down over the
upstand. Secure using six equally spaced Stainless Steel self-tapping screws. These must be driven down
through the rib-flange into the top of the Pump Well to secure the Riser.
ANCHORAGE
On most normal sites, the backfill over the Pump Well skirt described above will be adequate. However, where
the location is exposed to regular flooding or has high water table conditions, it may be necessary to provide
extra anchorage to prevent the Pump Well from moving if the soil is saturated and fails to remain as a solid
homogenous mass.
A quantity of concrete may be poured into the excavation and around the Pump Well to encase the vessel.
A concrete tube of 1220mm (outside diameter) and 850mm high around the vessel will have a mass of about
700kg, which will be sufficient to overcome the buoyant effect of a free-floating empty Pump Well.

IMPORTANT NOTES
"Pump Well" is a generic term for any vessel intended to temporarily store liquid before it is transferred by means
of a pump to another location, perhaps for processing or long-term storage. The EVERHARD Polymer Pump
Well has been tested and found to comply with the Australian/New Zealand standard for vessels such as Septic
Tanks and Collection Wells for use in domestic, and some other, situations.
It may be used to receive treated wastewater from a Septic tank for pumped discharge to a disposal area, or in
applications where site conditions dictate that short-term accumulations of “All-waste”, “Black-water” and/or
“Greywater” (defined by AS/NZS 1546.1) wastes must be delivered to a treatment system by a suitable pump
instead of free-flowing under gravity direct from the source.
Installers MUST check with your local authority to ensure that this pump well and usage will be permitted
in your area before beginning plans for any installation.
The EVERHARD Pumpwell was designed for on-site treatment and disposal applications. It is tested for
Standards Mark approval and does not carry WaterMark certification. Connection to sewer systems, and
installation in sewered properties, may not be permitted by local authorities.
The EVERHARD 250/450L Plastic Pump Well has a number of features which make it an obvious choice for
many installations. It is light and easily handled and worked with, while also being durable and tough. Produced
from a blend of polymer that has been stabilised against ultra-violet light degradation, its physical characteristics
allow the product to exceed the required performance criteria for the applicable tests in AS/NZS 1546.1.
In testing for resistance to lateral load, a critical part of the standard, the EVERHARD Polymer Pump Well was
subjected to side loading equivalent to the vessel being completely buried, a situation which a correctly installed
unit should never encounter. The Polymer Pump Well remained intact and suffered no permanent damage
whatsoever, despite extended exposure to the test load.
EVERHARD Polymer Pump Wells are ideally matched for use with the range of EVERHARD Polymer Septic
Tanks and Collection Wells, all produced in accordance with AS/NZS 1546.1. Other products available for
domestic wastewater applications include the popular EVERHARD Xtra-treat Filter which can be quickly and
easily fitted into the Outlet Fitting inside most Septic Tanks. These help prevent the discharge of solid particles
suspended in the treated fluid. An Xtratreat Filter can greatly extend the service life of the disposal system. The
EVERHARD range of disposal system equipment also includes effluent Distribution Boxes in Concrete and in
durable, tough Polymers. These complement the cost-effective and very efficient Polymer EVERTRENCH Trench
Liner for use in Evapo-Transpiration and Soakage treated waste-water disposal systems.
