Creek to Pipe Conversion


Tadros Engineering's specialist knowledge provides feasible engineering solutions from a financial, environmental, social and physical perspective. 


A section of a creek that meandered through a Client's property was converted to a pipe system to allow greater use of their property.  Environmental impacts were assessed and approved by the relevant authorities as part of the design process.


The success of this project ensured that there was an increase in useable land for the Client's use. 


Sewer Reticulation

Pressure Main 

Waste Water Reticulation

Flood Modelling

At Tadros Engineering we utilise XP SWIMM to conduct flood modelling studies to assess post and pre development scenarios.


Latest Project -  Baldivis


Hydraulic Modelling as per Department of Water’s (DoW) requirements


Run a hydraulic model based on the pre-filling ground elevation information to confirm the DoW flood levels are reproduced. (Pre-filling scenario)


Adjust ground elevations across the lot to adequately reflect the proposed filling and re-run the model. (Post-filling scenario)


Provide a comparison of the flood levels and extents for the above two scenarios to demonstrate the impact of the proposed filling on the flooding regime of the general area

Third Party Reviews

Professional Chartered Engineers at Tadros Engineering can provide Third Party Reviews if required.

Internal Sewer & Water Design for Buildings

We can provide any hydraulic design for your development needs in a standard or non-standard water supply system in a variety of situations and locations.



Roydhouse Subiaco
Services: Sewer Reticulation

Roydhouse Apartments required a DN225 sewer diversion along the basement wall of the development. Tadros Engineering's personnel designed and liaised with the Water Corporation to install this unique arrangement. Water Corporation has used this system as an example on future projects.

Urban Water Management Plans

We can provide Urban Water Management Plans (UWMP's)  incorporating input from Geotechnical and Environmental Engineers. 


As the designers of the subdivision, early input into the UWMP's ensures concepts proposed within the UWMP are able to be implemented within the design.  This assists to reduce the project delivery timeframe.
