Subject:                  Greywater Treatment and Water Re-use Systems

Folder No:                   F2007/00408

Author:                   Roman Wereszczynski, Manager Health, Building & Regulatory Services        

 

 

Introduction

 

The installation of water re-use systems in new development, is becoming an important and integral strategy to save our precious water resources and to manage the use of water in a sustainable manner.

 

Council has recently received and determined a number of applications under the Local Government Act to install and operate various types of greywater and other water re-use systems, a number of which are within the Prince Henry Hospital re-development.

 

To ensure that these applications are assessed and managed in a consistent and comprehensive manner, a standard procedure has been developed by Health Building & Regulatory Services.

 

Issues

 

The installation of water re-use systems is a relatively recent initiative, which should be encouraged and facilitated where possible. However, at this stage, government authorities, suppliers and customers are still learning about the detailed and complex regulatory provisions, guidelines and criteria which apply to these systems to maintain public health and safety.

 

The attached Environmental Health procedure aims to assist Council officers in the assessment and determination of applications for the installation and operation of waste water re-use systems, including grey-water treatment systems, diversion devices and other installations.

 

The procedure will also assist Council’s Environmental Health Officers in any associated regulatory activities, inspections and complaints relating to greywater and other water re-use systems.

 

The procedure outlines Council’s assessment, determination and inspection and procedures relating to waste water re-use systems, with a particular emphasis on greywater re-use systems, due to their sudden recent increased use within Randwick. 

 

The procedure also provides details of relevant legislative requirements, standards and relevant information to assist Council officers to effectively manage the installation and operation of such systems.

 

The procedure must also be read in conjunction with relevant legislative provisions, guidelines and criteria, which may be subject to change.

 

 

 

 

Relationship to City Plan

 

The relationship with the City Plan is as follows:

 

Outcome:  10 A Healthy Environment.

Direction:  10a Council is a leader in fostering environmentally sustainable practices.

 

Financial impact statement

 

There is no direct financial impact for this matter.

 

Conclusion

 

The attached standard procedure will help to ensure that applications for water re-use systems are assessed and determined in a consistent and effective manner, with minimal impact upon public health and the environment.

 

Recommendation

 

That the attached Health, Building & Regulatory Services standard procedure for on-site sewage management systems, grey-water treatment systems and other waste water re-use systems be noted.

AUTHORISED BY:                             Roman Wereszczynski

 

DATE:                                                June 2007 (updated March 2008)

 

PURPOSE:                                        To detail Council’s standard procedures and provide guidance for the assessment of applications to install and operate on-site sewage management, grey-water treatment systems and other water re-use systems & devices

 

 

1.      INTRODUCTION

 

This procedure aims to assist Council officers in the assessment and determination of applications for the installation and operation of ‘greywater’ reuse systems and similar devices and installations.

 

The procedure will also assist in any associated regulatory activities relating to ‘greywater’ re-use systems and the like.

 

This procedure outlines Council’s assessment, determination and inspection and procedures relating to ‘greywater’ re-use systems.  It also provides details of relevant legislative requirements, standards and relevant information to assist Council officers to effectively manage the installation and operation of such systems.

 

This procedure must be read in conjunction with relevant legislative provisions, guidelines and criteria, which may be subject to change.

 

2.      BACKGROUND

 

The installation of water re-use systems, particularly in new developments is becoming an important and integral strategy to save our precious water resources and to manage the use of water in a sustainable manner.

 

As the installation of water re-use systems is a relatively recent initiative, all parties, including Local and State government, Water Authorities, private companies and the public are endeavouring to manage the development and implementation of efficient and effective regulatory provisions, guidelines and criteria, which facilitate the installation and ‘take-up’ of these systems and also maintain public health and safety.

 

 

 

 

 

 

3.      REGULATORY PROVISIONS

 

General provisions

 

The installation and operation of ‘greywater’ re-use systems and other waste treatment devices or facilities are principally governed by the provisions of the Local Government Act 1993 and the Local Government (General) Regulation 2005.

 

In the Local Government (General) Regulation 2005, “greywater” is defined as ‘waste water from washing machines, laundry tubs, showers, hand-basins and baths, but does not include waste water from a kitchen, toilet, urinal or bidet’.

 

In addition, the installation of ‘greywater’ re-use systems and other waste treatment devices or facilities, which serve developments other than single residential dwellings (i.e. multi-unit housing developments, aged-care facilities, public buildings or commercial or industrial types of development), would generally also require development consent under the provisions of the Environmental Planning & Assessment Act 1979.

 

If development consent is necessary for the installation of the particular type of ‘greywater’ re-use system or other waste treatment device, this must be obtained prior to (or in conjunction with) the issue of any required approvals under the Local Government Act 1993.

 

 Local Government Act provisions

 

Chapter 7 of the Local Government Act 1993 contains the key provisions relating to the installation and operation of ‘greywater’ re-use systems and other waste treatment devices or facilities.

 

Part 1 of Chapter 7 contains the provisions and requirements relating to approvals and in particular, section 68 and the associated table to that section specifies the type of system or activity which requires an approval.

 

In the table to section 68, the following systems and activities require approval, unless specifically exempt from approval in the Local Government (General) Regulation 2005 (“the Regulation”):

 

·            C 5 - Install, construct or alter a waste treatment device or a human waste storage facility or a drain connected to any such device or facility.

·            C 6 – Operate a sewage management facility

·            F 10 – Carry out a prescribed activity, which includes the installation and operation of a ‘domestic greywater diversion’ system to a single residential dwelling, as detailed in clause 75A of the Regulation.

 

Part 2 of Chapter 7 contains provisions relating to the service of Notices and Orders, including in relation to the operation of a waste storage or treatment device (i.e.. if the system does not satisfy relevant criteria and standards or for public health and pollution control reasons)

 

The Regulation contains additional provisions relating to the installation and operation of such systems and devices. In particular, clauses 25 to 48 contain provisions relating to Approvals. Clause 75A contains provisions and exemptions relating to ‘domestic greywater diversion’ systems and devices and Clauses 82 to 100 contain provisions relating to the service of relevant Orders.

 

 

 

 

 

Environmental Planning & Assessment Act provisions

 

The requirement to provide or install greywater or other waste water treatment systems may arise as a result of the implementation of Council’s Local Environmental Plan and Development Control Plans for a particular site (i.e. Prince Henry Hospital Redevelopment). In such cases, a Development Application must be submitted to and approved by Council for the proposed greywater or other waste water treatment systems (usually in conjunction with the principle development).

 

Development Applications are assessed under the provisions of the Environmental Planning & Assessment Act 1979, Environmental Planning & Assessment Regulation 2000. Section 79C of this Act contains the matters for consideration (including the suitability of the site, environmental impacts, amenity impacts and public health and safety etc).

 

Generally, the installation and operation of a greywater or other waste water treatment system serving a multi-unit housing development or a commercial, industrial or public use development would require development consent as detailed above.

 

The installation of a greywater or other waste water treatment system serving only a single residential dwelling would in most cases not require development consent.

 

However, all greywater or other waste water treatment systems require an approval to install and operate the system under the provisions of the Local Government Act 1993, (except in relation to the installation of certain greywater diversion devices which may be exempt from an approval as detailed in the above Local Government Act provisions).

 

4.      RELEVANT GUIDELINES, STANDARDS & CRITERIA

 

As greywater and other waste water treatment systems recycle and re-use waste water from various uses within the particular development, the waste water has the potential to contain pathogens (i.e. bacteria, viruses, protozoa), chemicals (i.e. nutrients, salts, disinfectants, bleaches, oils) and physical contaminants (i.e. hair, lint, soap, dirt, sand, food waste).

 

Therefore, it is important to ensure that the system is suitably designed, installed and operated in accordance with relevant guidelines , criteria and standards to minimise the potential impact upon the health and well being of the occupants. As well as minimising any potential impacts upon the subject site, the environment and amenity of nearby residents.

 

There are various National and State guidelines and associated referenced documents relating to greywater treatment systems, greywater diversion devices and other waste water treatment and sewage management systems.

 

The guidelines contain detailed information relating to particular matters which should be taken into consideration when designing, installing and operating certain types of waste water systems. Unfortunately however, some of the guidelines and referenced documentation are quite complex and contain hundreds of pages of information, which may or may not be relevant to the particular proposal.

 

Generally, the guidelines and documents refer to the development and implementation of a ‘hazard analysis’ and ‘risk assessment’ approach, to ensure the suitability of the design and operation of the system and to satisfy public health and safety considerations.

 

The ‘risk assessment’ approach allows for each different and distinct system to be considered on its own merits and having regard to the relevant circumstances and the site and locality conditions in the particular case. However, the limited use and reference to prescriptive requirements and criteria can make the regulatory and application assessment processes extremely complex, time consuming and inconsistent.

 

The use of this procedure aims to ensure that Council provides a comprehensive, consistent and efficient process for the assessment and management of such systems.

 

The key relevant guidelines, referenced documents and criteria include:

It should be noted that the particular guideline/s and referenced requirements may not be mandatory and each application and proposal must be considered on its own merits, having regard to the relevant risks, site conditions and the environmental, public health and amenity considerations and impacts. As previously stated, in most cases, a hazard analysis and risk assessment approach is to be taken when considering the suitability of a particular proposal, except in relation to systems which are ‘accredited’ by a relevant authority (i.e. NSW Health).

 

Copies of the referenced guidelines and documents are contained in the Environmental Health Team Folder for Greywater and Other Waste Water Treatment Systems. A copy of the referenced guidelines is also contained in the relevant Trim Folder - F2007/00408. However, reference should be made to the relevant government department’s web site for any amended, updated or additional guidelines or criteria.

 

The NSW government has also issued a number of Information Sheets and other publications which should be referenced (as applicable), including:

 

·            DWE Fact Sheet # 1 – Greywater Diversion devices – Do’s & Don’ts

·            DWE Information Sheet – All About Greywater

As the use of greywater and other water treatment systems is increasing, new guidelines and information will continue to develop. Therefore, it is necessary to ensure that relevant staff, applicants and developers are informed of any new guidelines, criteria and information in this area and that they are appropriately referenced when designing and considering relevant applications.

 

5.      APPLICATIONS & APPROVAL REQUIREMENTS

 

Details of the application and assessment requirements are also provided in section 3 of this procedure ‘REGULATORY PROVISIONS’.

In summary, the following application and approval provisions apply:

 

Environmental Planning & Assessment Act 1979

 

A development application is required to be submitted to and approved by Council, for greywater and other waste water treatment systems provided to a class 2 to 9 development (as defined in the Building Code of Australia) i.e.. multi-unit housing developments, commercial developments and public building uses, unless the proposal is included in the application and consent for the overall development.

 

Local Government Act 1993

 

A local approval application is required to be submitted to and approved by Council, for:

 

·            The ‘installation’ of a greywater treatment systems or other waste water treatment system

·            The ‘operation’ of a greywater treatment systems or other waste water treatment system

 

For same-scale straight forward proposals (i.e. accredited greywater treatment system), the abovementioned applications may be included in the same application.

 

Exemption provisions (Local Government Act 1993 & LG (General) Regulation 2005)

 

Clause 75A of the Regulation contains provisions and exemptions relating to ‘domestic greywater diversion’ devices, subject to certain requirements, including:

 

·            Single residential dwelling use only

·            Compliance with the NSW Code of Practice – Plumbing & Drainage

·            The diversion device is a “WaterMark” licensed device

·            Greywater to be used for sub-surface irrigation only

·            Does not re-use waste water from a toilet or kitchen

·            Does not involve storage of untreated greywater

·            Compliance with health, safety and nuisance criteria

·            Must be installed by a licensed plumber

 

A list of current NSW Health registered greywater diversion devices is provided in Annexure 4.

 

A greywater diversion device uses a hand-activated switch to divert untreated greywater by gravity or a pump directly to a sub-surface irrigation system in the garden.

 

Applications & Approvals

 

Applications for a Development Application and Local Approval Application are required to be made on the standard DA or LA Application Forms, as applicable.

 

Applications are subject to payment of the approved Application Fee, as contained in Council’s current adopted Pricing Policy / Fees & Charges.

 

Application submission requirements depend on the type, scope and nature of the particular application and whether or not the system is accredited by the relevant authority or organisation.

 

In general terms, the applicant must provide sufficient details to demonstrate that the relevant legislative provisions, guidelines and standards will be satisfied and that the particular application should be approved.

 

Greater and more technical details would generally be provided with the Local Approval application to install and operate the system.

 

In summary, application submission requirements include (as applicable):

 

·            Application form

·            Application fees

·            Plans & Specifications

·            Manufacturers details

·            Design certification

·            System accreditation details

·            Description of the system, sources of recycled water, quantity of water, end-uses of recycled water & quality of water etc

·            Monitoring plan (including validation & verification)

·            Operational, maintenance and ongoing management details

·            Other information and details as may be relevant to the proposal

 

The extent of details will depend on a number of factors, including the type of application and proposed system, relevant environmental and public health considerations, applicable guidelines & criteria. For example, comprehensive details of the risk assessment, monitoring plan, operational and management of the system would generally be included in the application to ‘operate’ the system. However, the application to ‘install’ the system should include sufficient details of these considerations and proposed strategies, to demonstrate that the relevant provisions and criteria can and will be satisfied.

 

If the applicant has adequately demonstrated that the relevant criteria and considerations will be satisfied and the proposal is considered acceptable, the application may be approved, subject to a number of standard conditions.  Non-standard conditions may also be included to address the particular circumstances of the case and any issues of concern or the like.

 

Consideration is also required to be given to any relevant conditions of accreditation eg. NSW Health conditions of accreditation for a particular greywater treatment system (as identified in Annexure 3).

 

A copy of the current standard DA and LA conditions for greywater treatment systems and other waste water treatment systems is provided in Annexure # 1. These conditions are also contained in the standard DA Conditions for all development.

 

A copy of an example Local Approval determination and condition of approval for a greywater treatment system serving a multi-unit housing development is provided in Annexure # 2.

 

 

 

Referrals to Other Authorities

 

Although not mandatory, it is agreed practice to refer all applications for greywater and other wastewater treatment systems (serving class 2 to 9 developments) to the NSW Department of Water & Energy and the Department of Health for comments prior to Council’s determination of the application.

 

These authorities may request (via Council) further information from the applicant to demonstrate that the relevant guidelines and criteria will be satisfied.

 

The comments, recommendations and conditions made by the NSW Department of Water & Energy and the Department of Health must be taken into consideration and into the terms of any approval (unless specifically determined otherwise by the Council, General Manager, Director or Manager).

 

A copy of Council’s determination should be forwarded to the authorities, if requested by the authority.

 

6.      ADMINISTRATION PROCEDURES

 

Details of all applications, Development Applications (DA) and Local Approval (LA) applications are required to be recorded in Council’s Pathway Applications system, in accordance with the Health, Building & Regulatory Services – Business Rules for Applications.

 

Details of all approved greywater and other waste water / on-site sewage management systems are to be maintained in Council’s Pathway Licensing system, in accordance with the Health, Building & Regulatory Services – Business Rules for Licensing / Registrations.

 

Upon determination of a LA to ‘install’ a greywater treatment system or other on-site sewage management system (excluding a greywater diversion device), details are to be recorded in the Pathway Licensing system and the licence / registration identified as ‘pending’. Upon commencement of the ‘operation’ of the system, the status of the licence/ registration is to be changed to ‘current’.

 

7.      INSPECTION & CERTIFICATION

 

An inspection of proposed and installed greywater treatment system or other on-site sewage management system (excluding a greywater diversion device) should be carried out at the following stages or occasions:

 

·            Upon lodgement of the DA and LA

·            Upon completion of the installation of the system

·            Upon operation of the system (i.e. after validation and verification, if applicable)

·            Periodically (eg. annually for black-water OSSM and bi-annually for a grey-water or other water  re-use system, or as otherwise as is considered appropriate for the type of system and development)

·            Upon receipt of a resident complaint or concern relating to the system

 

Certification should be obtained from a suitably qualified person/s at various stages of the process, to demonstrate that the particular system satisfies relevant design, installation and operational requirements and criteria.

 

During the application assessment process, ‘design certification’ should be obtained, which specifies the applicable design requirements and guidelines and confirms that the design satisfies the relevant guidelines and requirements.

 

Design certification is not required to be provided for a greywater treatment system or other system which is Accredited by the NSW Health Department or other recognised accreditation body.

 

A copy of current NSW Health Accreditation details for greywater treatment system are provided in Annexure 3.

 

Certification should also be obtained at the following stages or occurrences (and be specified in the relevant conditions of approval):

 

·            Upon installation of the system (prior to operation)

·            Upon completion of the required validation and verification testing (as detailed in the DWE Guideline – Management of Private Recycled Water Schemes)

·            Annually, from the date of commencing the operation of the system (as detailed in the DWE Guideline – Management of Private Recycled Water Schemes – ‘Audit reporting’)

·            Upon the written request of Council

 

The certification must be sufficiently detailed and accurately refer to the relevant requirements, guidelines, criteria, standards and codes of practice etc. In some cases, certification may need to be provided by different parties, depending on the scope of the particular matter or certification (i.e. certification from a environmental / public health consultant for health and environmental matters and certification from a Licensed Plumber in relation to the installation of the equipment, pipes and drainage in accordance with AS 3500 and the Code of Practice)

Environment Report No. E9/08

 

 

Subject:                  Water Savings project at Administration Building

Folder No:                   F2004/06495

Author:                   Peter Maganov, Manager Sustainability     

 

Introduction

 

Seeking approval for a major water saving project at the Administration Building.

 

Issues

 

Council has recently been advised that the Minister for Environment and Climate Change has agreed to sign the draft Water Savings Action Plan prepared for Randwick under mandatory requirements expected of local government and other larger water-consuming organizations in NSW.

 

Implementation of each of the Water Savings Action Plans approved by the Minister is the next stage of scrutiny by the Department of Environment and Climate Change. In Randwick’s case much of the implementation has been underway for more than 12 months through projects funded via the Environmental Levy program and Council’s Sustaining our City initiative. Projects in this category include those carried out at the Works Depot, Community Nursery, Des Renford Aquatic Centre and Recycling Centre.

 

The largest area of water consumption within the Administration Building occurs within the air conditioning plant. Air conditioning at this site consumes just over 60 percent of the Administration Building’s water consumption.

 

To identify water-saving options within this area of operation, Council staff have supported final year engineering students from UNSW during 2007 and 2008 undertaking investigations and options for the collection of rainwater for re-use in the air conditioning plant. This has resulted in a number of options including the placement of rainwater tanks inside the plant room or rainwater tanks in the basement. Either way, captured rainwater from the roof will be pumped to supplement air conditioning water requirements from the current town water connections.

 

The designs and costing for these various options have been considered separately by a water engineering consultant who has identified a number of additional cost savings for this project. Three quotes have now been obtained and indicate the full cost of installing 20,000 litres of rainwater storage, plumbing and pumps etc for supply of rainwater to the air conditioning plant is approximately $28,000.

 

There are a number of additional issues for consideration in relation to the implementation of this water saving initiative. Issue 1 involves the placement of 4 rainwater tanks in the basement between the last parking spaces and the wall alcoves in the centre areas of the basement carpark. The advantage of this location is the additional height within the basement area providing greater storage capacity and volume of water available for the air conditioning. This area is not available as a formal parking space, however it does occasionally get used as a temporary area for a vehicle “spill-over” for one vehicle.

 

The other item is the energy used to pump from the basement rainwater tanks to the plant room. Although the pump selected has a high energy efficiency and very low noise output, there will be more energy consumed to operate the pump in the basement than in the plantroom. The tradeoff is that more water can be captured and stored in the basement than in the plantroom.

 

To address this additional energy consumption, consideration will be given to the installation of a small scale wind turbine or appropriate source of renewable energy offset for the Administration Building.

 

Relationship to City Plan

 

The relationship with the City Plan is as follows:

 

Outcome:          10 A Healthy Environment.

Direction:          10(a) Council is a leader in fostering environmentally sustainability                   practices.

                       10 (f) A total water cycle management approach including water                            conservation, re-use and water quality improvements is adopted.

 

Financial impact statement

 

Funding for this project will be carried out from the Water Conservation budget of the Environmental Levy program. Costs of the project will not exceed $28,000.

 

Conclusion

 

This project will provide a positive response to the issues raised in Council’s mandatory Water Savings Action Plan approved by the Minister for Environment and Climate Change and implement a major water savings initiative within the Administration Building. An additional benefit from this project is the contribution provided by final year engineering students as part of their studies at UNSW.

 

Recommendation

 

That Council approves the installation of the rainwater storage and re-use systems as described for the air-conditioning plant in the Administration Building at Frances Street.

Environment Report No. E10/08

 

 

Subject:                  Workplace Travel Access Plan

Folder No:                   F2004/08350

Author:                   Peter Maganov, Manager Sustainability     

 

Introduction

 

To seek approval to prepare a Workplace Travel Access Plan for Council staff.

 

Issues

 

Council currently has a number of important initiatives in place for Randwick staff and the community in relation to improving sustainable transportation choices that they can take. This includes the provision of carshare vehicles, designated parking for carshare and hybrid vehicles and continuing expansion of cycling facilities and network within Randwick City.

 

In relation to staff, efforts are underway to consolidate and communicate processes for use of the corporate bicycles and staff access to the carshare vehicles. Investigations are also underway to support incentives to support annual public transport ticketing for staff.

 

As a means of articulating Council’s commitment to improving sustainable transportation choices for staff, it is proposed to prepare a Workplace Travel Access Plan. This Workplace Travel Access Plan will set out the relationship of sustainable transportation choices for staff with Council’s 20-year City Plan, would include a summary of results of the staff travel survey carried out in late 2007 and identify key initiatives underway or for future consideration. Once approved it is proposed to update the plan on a two-yearly basis as a means of keeping actions up-to-date and informing Council on the results of effort underway.

 

Relationship to City Plan

 

The relationship with the City Plan is as follows:

 

Outcome:  (9) Integrated and Accessible Transport.

(10) A Healthy Environment.

 

Direction:  (9b) The community is informed, educated and encouraged to use                          sustainable transport.

(10b) Council is a leader in fostering environmentally sustainable             practices.

 

Financial impact statement

 

There is no direct financial impact for this matter.

 

Conclusion

 

The preparation of a Workplace Travel Access Plan will provide a framework for the existing sustainable transport choices on offer and under consideration for Council staff. Such a framework would remove the adhoc nature of existing measures and place them within the strategic framework provided by Randwick’s 20-year City Plan.

 

 

Recommendation

 

That Council agrees to the preparation of a Workplace Travel Access Plan.
