Abstract
Property-level stormwater drainage systems consist of roof drainage systems and those systems that connect buildings and their surrounding ground surfaces to main sewer networks, on-site rainwater harvesting or other capture systems. The design of these local systems has traditionally been based on simplistic approaches that fail to account for performance and integration. Given the extra demands associated with climate change, these limitations will take on increasing importance due to the potential for site-level flooding or water damage. To address the concerns, new tools are needed to describe and assess performance as well as to enable a more integrated approach. Research is presented on the development of an integrated property-level drainage simulation model and associated whole-life costing model. Application of the model illustrates the importance of accounting for flow interactions in order to assess the hydraulic effectiveness of different adaptation schemes. Similarly, the whole-life cost model can determine the through-life costs of adaptation strategies, hence enabling the assessment of the cost effectiveness of integrated designs.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
