  • Benchmarking energy consumption and CO2 emissions from rainwater harvesting systems: an improved method by proxy 

    Ward, Sarah; Butler, David; Memon, Fayyaz (IWA (International Water Association), 2010)
    Life cycle analyses (LCAs) show the main operational energy contribution for rainwater-harvesting (RWH) systems come from ultraviolet (UV) disinfection and pumping rainwater from tank to building. Simple methods of estimating ...
  • Compliance with the Urban Waste Water Treatment Directive: European Union City Responses in Relation to Combined Sewer Overflow Discharges 

    Ward, Sarah; Butler, David (Thames Water, 2009-08-25)
    Compliance with the European Union Urban Waste Water Treatment Directive (‘the Directive’) is a pre-requisite for achieving the primary objective of the Water Framework Directive. 11 EU-27 Member States had to comply with ...
  • Engineers and planners: Sustainable water management alliances 

    Potter, Karen; Ward, Sarah; Shaw, Davis; Macdonald, Neil; White, Iain; Fischer, Thomas; Butler, David; Kellagher, Richard (ICE Publishing, 2011)
    In the future, increasing pressure will inevitably be placed on the spatial planning system to improve its consideration of water management issues. Emerging challenges include designing for climatic extremes, reducing ...
  • A framework for supporting rainwater harvesting in the UK 

    Ward, Sarah; Butler, David; Barr, Stewart; Memon, Fayyaz (IWA Publishing, 2009)
    Numerous policy vehicles have been introduced in the UK promoting the use of rainwater harvesting (RWH). However, an 'implementation deficit' exists where legislation limits action by failing to provide adequate support ...
  • Harvested rainwater quality: the importance of appropriate design 

    Ward, Sarah; Memon, Fayyaz; Butler, David (IWA Publishing, 2010)
    This paper summarises the physicochemical and microbiological quality of water from a rainwater harvesting (RWH) system in a UK-based office building. 7 microbiological and 34 physicochemical parameters were analysed during ...
  • A new approach to urban water management: Safe and Sure 

    Butler, David; Farmani, Raziyeh; Fu, Guangtao; Ward, Sarah; Diao, K.; Astaraie-Imani, Maryam (Elsevier, 2014)
    This paper introduces a new approach to water management that is 'Safe & SuRe'. This includes presenting a conceptual framework to link the emerging threats of climate change and variability, rapid urbanization and population ...
  • A pilot study into attitudes towards and perceptions of rainwater harvesting in the UK 

    Ward, Sarah; Butler, David; Memon, Fayyaz (2008)
    Rainwater harvesting (RWH) has been identified as having dual benefits - as an alternative water supply, which helps reduce demand on potable supplies and as a stormwater detention method to help relieve urban flooding. ...
  • Rainwater harvesting: model-based design evaluation 

    Ward, Sarah; Memon, Fayyaz; Butler, David (2008)
    The rate of uptake of rainwater harvesting (RWH) in the UK has been slow to date, but is expected to gain momentum in the near future. The design of two different new-build rainwater harvesting systems are evaluated using ...
  • Robust rainwater harvesting: probabilistic tank sizing for climate change adaptation 

    Lash, Daniel; Ward, Sarah; Kershaw, Tristan; Butler, David; Eames, Matthew E. (IWA Publishing, 2014-12-10)
    Rainwater harvesting (RWH) systems are increasingly being implemented in buildings. It is common in the UK for simple RWH tank sizing methods to be utilised, and these do not consider future climate change. This paper ...
  • Scenario-based sustainable water management and urban regeneration 

    Farmani, Raziyeh; Butler, David; Hunt, Dexter V.L.; Memon, Fayyaz; Abdelmeguid, Hossam; Ward, Sarah; Rogers, Chris D.F. (ICE Publishing, 2012)
    Deployable output (source availability) from water resources in north west England is predicted to decrease over the next 25 years. Alternative supply management strategies are planned to help avoid a deficit in the ...
  • Water sensitive urban design in the city of the future 

    Ward, Sarah; Lundy, L.; Shaffer, P.; Wong, T.; Ashley, Richard; Arthur, S.; Armitage, N.P.; Walker, L.; Brown, R.; Deletic, A.; Butler, David (2012)
    With timeframes for addressing the issues of the City of the Future (CotF) rapidly approaching (e.g. 2020, 2025, 2050), this paper integrates international research knowledge and expertise from four continents. It critically ...
