SECTION 01 50 00 Page 11

PFAS Investigation and Management Branch

Provision of Treated Water for Defence Construction Projects

Purpose:

To provide guidance in reviewing requests from other Defence projects (the Proponent) to receive treated water for use in construction from one of the water treatment plants (WTP) managed by PFASIM Branch (PFASIMB) and currently operating at RAAF Williamtown, RAAF Tindal, RAAF Edinburgh and the Army Aviation Centre Oakey.

Scope:

This guidance currently applies only to requests from construction projects on one of the four Defence Bases at which a WTP to treat PFAS contaminated water is already operational.

Responsibilities:

All Proponent requests are to be submitted to the Defence PFASIM Project Director (PFASIM PD) responsible for the WTP site.

The Proponent should provide sufficient information on the project and its water requirements to allow the request to be adequately assessed by the WTP Operator and Defence.

The PFASIM PD is to inform PFAS Estate Management once a request is received.

Initial Request to PFASIM Branch

1. PFASIM PD contacted by the Proponent with details of the request for treated water including as a minimum:

Project Reference Number;

Project Name and Scope;

Project Sponsor details;

Project start and end dates;

Project Site/Location;

Estimated volume, frequency and duration for which water is required; and

Point(s) of contact for correspondence.

2. PFASIMB review the request and provide initial feedback and if deemed appropriate, preliminary, in-principle support to the request within 5 working days.

3. PFASIMB forward the request details and any preliminary feedback within 5 working days to the WTP Operator for their further review and assessment.

Information Requirements

4. The WTP Operator will review the request to determine any additional requirements that need to be addressed and any costs that need to be covered by the Proponent.

Payments of any additional costs that need to be covered by the Proponent are to be paid direct to the WTP Operator on terms agreed between the Proponent and WTP Operator.

These considerations could include, but are not limited to:

a. any additional storage or infrastructure and operator resourcing that may be required to provide the Proponent with water;

b. situations that could result in treated water being temporarily unavailable to the project;

c. arrangements for filling of buffer storage tanks, if required, for occasions when treated water might not be available to the project;

d. The Proponent having its own backup option to purchase/obtain water from a supplier should WTP treated water become unavailable;

e. Provision of a notice period should the WTP needs to be shut down for maintenance or operational reasons; and

f. Agreement between the Proponent and the WTP Operator of any supply restrictions which will be at the WTP Operator’s discretion taking into account any operating, maintenance or other priorities as determined from time to time by Defence.

5. Once the above and any other considerations have been evaluated and mutually agreed, the methods of transferring the water from the WTP, including any additional infrastructure/equipment requirements and a proposed schedule for implementation need to be prepared by the Proponent for review and endorsement by PFASIMB, Base Representatives and WTP Operator.

6. Any cost proposal from the WTP Operator is not to include a fee for provision of treated water.

7. Following WTP Operator consideration of the Proponent’s request, the WTP

Operator provides the PFASIM PD with a written recommendation and/or a request for further information.

8. Subject to the WTP Operator advising that the WTP can provide water with no impacts to the remediation provision of services under the contract with Defence, the PFASIM PD notifies the Proponent and WTP Operator of the decision and/or requests further information.

9. If the Proponent’s request is approved by Defence and the WTP Operator, management for establishing the arrangement and managing compliance is the responsibility of the Proponent and WTP Operator.

10. The PFASIM Branch Remediation team is to be kept informed and will only intervene if required.

11. The WTP Operator should include in its current reporting to Defence the volume of treated water that has been provided to the Proponent.

Additional Considerations:

12. Any additional costs incurred from providing the Proponent with water that are above the normal operating costs of the WTP are to be met by the Proponent. This may include equipment, transport costs, plant maintenance operator costs, overtime or other relevant costs. Any associated invoicing and payments may be managed directly between the Proponent and WTP Operator but commercial arrangements should be assessed and established on a case by case basis. It should be noted that costs covered by the Proponent do not constitute a contract obligating the WTP to provide water to the Proponent. Any operating, maintenance or other priorities as determined by Defence may take priority for water use.

13. The WTP Operator shall provide the Proponent with water that has been treated sufficiently to not cause pollution when used in construction including for dust suppression and wetting down of materials. However, the Proponent is to satisfy themselves that use of the treated water will not cause pollution to the environment and will comply with any legislation, regulatory requirements or other relevant guidelines.

14. Any cost savings against agreed contract payments that result from water being supplied from the WTP, rather than purchased from an external supplier, are to be returned by the Proponent to Defence (via the project budget associated with the construction water requirements). A statement summarising the volumes of water provided and costs saved should be sent to the PFASIM PD.

15. Any additional equipment is to be procured, supplied and managed by the Proponent but installation shall be in agreement with and may be managed by the WTP Operator and in compliance with the Base and any approved ECC or SSB conditions.

Where this cannot be accommodated within current approvals, it is the Proponent’s responsibility to secure the necessary approvals.

16. The Proponent is responsible for obtaining ECC or SSB approvals, if required.

17. The Proponent acknowledges that there may be circumstances under which the arrangement needs to be temporarily interrupted, volume of supply reduced, or supply totally terminated. Where possible notice will be provided to the Proponent of such circumstances. If such circumstances arise, the Proponent is responsible for making and meeting the costs of alternative arrangements and any penalties or costs arising to the Proponent under these circumstances are the Proponent’s responsibility.
