Description:

The water supply booster pump station is a component of the reticulation system and will pump to

an elevated water supply storage tank upon demand. The operation of the pump will be governed by

a low water level signal from the tank.

Objective:

The objective of the water supply booster pump station is to provide a water supply that meets the

customer demands for reliability of supply and flow.

Component Description:

1. Pump Station Site

The pump station site is to be located within a reserve in favour of the

Goulburn Valley Region Water Corporation.

The pump site is to be selected where a sufficient water supply is provided at

peak periods for the pump to operate (water pressure and flow). Advice is to

be sought from Goulburn Valley Waters Planning and Project Development Section.

The site is not to be encumbered by existing or proposed overhead power

lines and is to provide satisfactory coverage for monitoring and control via

SCADA.

The site must be accessible by vehicles by means of an all weather road. The

minimum width of the access is 3 metre wide and sufficient space is to be

provided for a light truck vehicle to turn and for at least 1 parking space.

The surrounding area of the pump station site is to be covered with a

minimum of 100mm compacted crushed rock or similar approved material to

provide an all weather access to the site.

The layout of the pump station must ensure that the available space for

maintenance purposes is maximised. A minimum of 1 metre clearance

between all assets and the reserve title boundary must be achieved.

2. Electricity Supply

The capacity of the electricity supply system needs to be investigated to

ensure that there is an electricity supply capable of meeting pump station

loading within electricity supply regulations for both Amperage and Voltage.

If a development project, then the connection to the grid is to be arranged by

the consultant including the meeting of associated costs as part of the

project. These include:

Costs to hook into grid

Expected running costs of pump annually and life time

Pump wiring requirements,

Generator change over ability

All weather control box

3. Switchboard

The electrical cabinet and switchboard is to be in accordance with the GVW

Standard Specification for Switchboards. This is available upon request via

email to [email protected]

GVW General Electrical Specification

4. Perimeter Fence

The site perimeter is to be fenced with a 1.80m high black plastic coated

chain mesh security fencing around the complete site boundary.

A minimum 3m wide black plastic coated chain mesh security hinged double

gate with padlock keyed is to be provided at the entrance to the site.

Minimize aesthetic issues for neighbouring properties and the general public.

This may require perimeter buffering planting or screens and should be

investigated with Council and local residents. Please refer to the GVW Building

Aesthetics Design Manual.

5. Pumps

All booster pump stations that boost water supply to an elevated water supply

storage tank are to equipped with 2 No. complete and identical pumpsets,

(duty and standby) and are to be rated to operate in an open weather

environment.

The selection of the pump and the design of the inlet water main to the

storage tank should minimise the pressure spike to customers to 5 metres

head, if there is a single inlet/outlet pipeline to the tank. The preference is

dedicated inlet and outlet water mains.

The noise generated from the start, stop and running of the pumps is to be

considered and must comply with EPA requirements. If noise is an issue to

neighbouring properties, then sound attenuation measures, such as an

enclosure should be considered.



6

Pumps should be located adjacent to the access/parking area, so that there is

unrestricted access to pumps to allow lifting as required using a small GVW

crane truck.

Pumps and pipework are to be secured to a suitable concrete slab, which

drains surface water adequately.

6. Pump Controls

The pumps are to operate on a duty call and duty stop set point from the

storage tank. There is to be a telemetry (radio) link between pumps station

and storage tank.

Cable is not to be used when the distance between the pumps and the tanks

is greater than 100m.

The pumps should have an automatic changeover between the duty and

standby.

The preferred arrangement is for the water level in the storage tank to be

relayed to the pump station, which displays all information and is connected

to SCADA.

7. Pipework

All pipework in the vicinity of the pumps is to be above ground and comprise

flanged or welded stainless steel or flanged DICL pipework.

Inlet and outlet pipes to be cast into the 100mm thick reinforced concrete

slab.

All below ground pipe work within the pump station site must be DICL

material.

8. Electromagnetic Flow Meter

A magnetic flow meter is to be installed on the discharge pipework from the

pumps and located above ground.

Installation must comply with the electromagnetic flow meter design guideline.

The discharge flow rate is to be displayed on the electrical cabinet and also

linked to SCADA, so that it can be viewed remotely.

9. Standard Drawings and Site Photos

Site layout plan for Avenel Park Water Supply Booster Pump Station

(JWS/2062)

A post construction review of the pump station indicates the following changes

should be made for future similar pump stations:

Control cabinet is located between the pumps and the access. This requires any pumps to be lifted over the control cabinet for maintenance

and repairs. The control cabinet could have been located at the other

end of the pump slab.

Aesthetics Neighbouring land owners have complained that the pump station is unsightly, and shrubs are to be planted along the frontage to

the pump station. This could have been addressed during the design

stage, by requesting that the developer get approval for the pump

station from Council and the adjacent land owners. Please refer to GVW
