Water Engineering Services

Water & flood engineering services – Wollongong & NSW South Coast

Rienco’s engineering consultants are experts in floodplain and stormwater management

At Rienco Consulting, we specialise in all aspects of water engineering. From designing flood related infrastructure, to detailed hydraulic and hydrologic investigations, to advise on development within the floodplain and analysis of recorded hydrologic data.

We have particular expertise in surface water hydrology, surface water hydraulics, water sensitive urban design, and stormwater management.

Our consultant hydrologists can help you

  • Obtain Council approvals – we carry out flood studies and associated investigations to assist you in obtaining your consent
  • Determine the flood constraints and opportunities across you land – we assess your exposure to flood hazard, and provide advice on how to mitigate the effects of flooding
  • Look at the quality of your surface water and design solutions if there are problems
  • Assess your project stormwater requirements, and design infrastructure to manage it

Flood Assessments & Management Plans

Surface water hydrology looks at the properties and flow of water, and how it behaves in different environments.

Rainfall Data Collection & Analysis

We use hydrologic modelling to understand the volumes of water flowing into, or out of, a catchment at any one time.

Stormwater Modelling and Planning

Water sensitive urban design is an engineering planning and design approach which is more considerate of the water cycle.

What our customers say


In my capacity as an architect I have worked with Anthony on a large number of projects throughout the Wollongong area. Anthony has a deep knowledge of local stormwater issues, and in particular the risks and mitigation strategies that should be applied. He is very experienced in the requirements of local councils and has contributed to many successful applications of all scales, from renovations to developments and subdivisions. I can wholeheartedly recommend Anthony and the Rienco team for their practical and professional approach to assessing and solving stormwater related conditions, and as effective advocates in dealing with the council planning controls.

I use Rienco for all flooding and drainage matters on my projects because of their flooding modelling skills and pragmatic understanding of the difficulties of land development. The top-line integrity of their work was demonstrated recently on a very contentious project where the Rienco report passed a rigorous peer review by one of Australia's leading hydrology firms, with no change to the original findings and recommendations. It's comforting to know with Rienco you have that clarity of thinking helping find the best solution, and the confidence that it will be right.
