Engineer Design Approvals

The developer may be required to submit detailed engineering plans to TasWater for approval for issue of an Engineering Design Approval. The engineering plans must include details of the extensions to TasWater mains and/or connections to TasWater infrastructure.

Construction

The contractor needs to obtain a Permit to Construct prior to commencement of the construction of infrastructure intended to be ‘gifted’ to TasWater.

  • The Permit to Construct will provide details on:
  • required TasWater inspection including "hold" points
  • testing compliance criteria
  • as constructed plans
  • practical completion and final acceptance requirements
  • security bonds and defects liability period.
An application for new connections is required for connections to existing infrastructure, connections for a “connections only subdivision” and for removal of redundant connections.

 

Plan of Subdivision - Following the issue of a TasWater Practical Completion Certificate, the developer may lodge the Plan of Subdivision with council and request the Council to ‘seal’ the Plan.
Council will seek confirmation that all TasWater permit conditions have been met, including payment of developer charges (if applicable). TasWater will issue a Certificate of Approval of the Plan of Subdivision to Council if all conditions have been met.

Following approval of conceptual design via a  Development application to council and TasWater’s SPAN, you are required to submit an application for Engineering Design Approval (EDA) directly to TasWater. This process will involve assessment of the detailed design and the outcome will be a set of endorsed engineering plans including conditions for the development.

Once you have been granted EDA, a TasWater Field Services Officer will contact you to arrange a Pre-Start Meeting. At this meeting the TasWater officer will discuss your development and is able to clarify any questions you may have regarding specifications or requirements. Following the Pre-Start Meeting, you can apply for a Permit to Construct that enables you to start construction and will include any specific requirements for your works and detail the testing and witness points. You can apply for a Permit to Construct using a Development Services application form and emailing the completed application to TasWater on development@taswater.com.au 

It is important that construction does not commence without a Permit to Construct as you may discover important elements that need to be considered after you have installed assets. This may mean you have to expose or re-lay infrastructure incurring unnecessary cost to your development.

 

Rezoning process

Rezoning of land to enable development is legislated under the Land Use Planning and Approvals Act (LUPAA). Section 34 of LUPAA deals with the rezoning of land (amendment to a Planning Scheme) while Section 43 enables assessment of both the rezoning aspect, along with an application for development of the land after the rezoning.

As with other development applications, council will refer these applications to TasWater for assessment. TasWater will make a representation (Submission to Planning Authority Notice (SPAN)) to council in respect to its requirements for the rezoning and development. 

Rezoning application

Where water and sewerage services are required, a rezoning application triggers the necessity to review the capability of TasWater infrastructure to service the land (“serviced land”). There are essentially two scenarios, namely that:

  • rezoning of unserviced land may result in an extension to TasWater’s serviced land boundaries
  • rezoning within serviced land may increase the demand on hydraulic infrastructure.

The implication for land developers, is that more comprehensive investigations into external impacts outside of the land under consideration for rezoning, are likely to be required. TasWater will need to review the infrastructure and funding arrangements, which may result in an increase to developer charges for infrastructure outside of the subject land.

As part of the application to council the developer will be required to submit a report and Concept Servicing Plan. Depending on the complexity, hydraulic modelling may be required. Where further information is sought the ‘clock stops’ and the timeframe recommences when satisfactory additional information is received.

Once satisfied with the information TasWater will issue a “Submission to Planning Authority Notice” (SPAN) to council and this will form an attachment to the planning permit that may be issued by council.

 

Subdivision and boundary adjustments

As with any other development application to council, when a subdivision application is made to council, requesting a planning permit, this application is referred to TasWater in accordance with the Water and Sewer Industry Act 2008.
The developer is required to submit a report and Concept Servicing Plan addressing the following key elements (depending on the size and location of the subdivision):

  • existing and proposed hydraulic infrastructure with service connections
  • additional demands from the water network and additional loads on the sewerage network
  • preliminary hydraulic network analysis model such as H2OMap-Water and Infoworks-CS

The proposal should generally be in accordance with the Water Services Association of Australia Water Supply Code and Sewerage Code, and as amended by TasWater’s Supplements, and all other relevant published standards.
Any areas/lots should be identified that cannot be served by gravity sewer and that do not meet the TasWater water and sewerage service level requirements.

TasWater may invite you to a meeting to discuss the proposal. Following discussions with council, the developer may be required to prepare a Final Report and Concept Servicing Plan. Once satisfied with the information TasWater will issue a “Submission to Planning Authority Notice” (SPAN) to council and this will form an attachment to the planning permit that may be issued by council.

TasWater will assess the servicing requirements for water and sewer for the development and also the impact on any TasWater infrastructure that may be impacted by the development.

TasWater must either:

  • ask for further information in respect to the application within 7 working days. Where further information is sought the ‘clock stops’ and the time-frame recommences when satisfactory additional information is received
  • respond within 14 calendar days stating that there is no objection to the granting of the permit
  • respond within 14 calendar days stating that there is no objection to the granting of the permit subject to conditions specified by TasWater
  • respond within 14 calendar days stating that TasWater objects to the granting of a permit along with the reasons.

Once satisfied with the information TasWater will issue a “Submission to Planning Authority Notice” (SPAN) to council and this will form an attachment to the planning permit that may be issued by council.

The developer will generally, as a minimum, be required to:

  • provide a 20 mm water connection to each lot for serviced land
  • provide a 100 mm sewer connection to each lot for serviced land
  • extend water and sewer mains as required to achieve the required individual connections.

These minimums may be required to be exceeded depending on the individual circumstances of the development

Combined amendment and planning permit application

As part of the application to council the developer will be required to submit a report and Concept Servicing Plan, addressing the following key elements:

  • existing and proposed hydraulic infrastructure with service connections
  • additional demands from the water network and additional loads on the sewerage network
  • preliminary hydraulic network analysis model such as H2OMap-Water and Infoworks-CS.

The proposal should generally be in accordance with the Water Services Association of Australia Water Supply Code and Sewerage Code, as amended by TasWater’s Supplements and all other relevant published standards.

Any areas/lots should be identified that cannot be served by gravity sewer and that do not meet the TasWater water and sewerage service level requirements.
Where further information is sought the ‘clock stops’ and the time-frame recommences when satisfactory additional information is received.

TasWater may invite you to a meeting to discuss the proposal. Following discussions with council, the developer may be required to prepare a Final Report and Concept Servicing Plan. Once satisfied with the information TasWater will issue a “Submission to Planning Authority Notice” (SPAN) to council and this will form an attachment to the planning permit that may be issued by council.

The SPAN will include the rezoning advice together with conditions which form part of the proposed recommendation and permit that the council will lodge with the Tasmanian Planning Commission for determination.

TasWater incurs a greater cost to consider a combined rezoning application/subdivision application compared with only a subdivision application. As such TasWater’s fee schedule provides for a separate fee for rezoning and a separate fee for the subdivision application
