Technical Standards

Conditions of Use:
TasWater specifications, drawings and approved product lists have been prepared to assist in the design and construction of water and sewerage infrastructure. The documents are designed to be used in conjunction with each other and where applicable by a suitably qualified person in combination with your development services application. TasWater does not consider the documents suitable for use for any other purpose.

The documentation only provides the minimum requirements and in some instances generic information only. The information on this website should not be regarded as either comprehensive or an adequate substitution for further investigation or input from a suitably qualified person.

It is the responsibility of the designer to ensure that designs comply with all the relevant Australian Standards and other regulations.

It is the responsibility of the designer and the developer to ensure that safe construction methods are used and that the construction work complies with the approved design drawings and all the relevant standards and regulations.

Use of these documents for any purpose which is not consistent with the above (including, without limitation, for carrying out any investigations, design, construction, engineering, maintenance or other work), is undertaken at your own risk.

Terms and conditions - Schedule of Easements and transfer

These are TasWater’s standard easement precedents for use with a Schedule of Easements and transfer. They provide for the rights that are to attach to any easement TasWater is granted. They do not define the relevant parcel of land or the part of that land that the easement is granted over.

The inclusion of these things is the responsibility of the relevant legal practitioner preparing the documentation. The Schedule of Easements precedent includes a place for the relevant lot and easement land to be directly inserted. The precedent to be used with a transfer will require the inclusion of the relevant land and easement land in the transfer by reference to the certificate of title and plan that is used for the purposes of the creation easement.
