The concept of eco-city planning appears to have been established in North America during the mid-1970s with the Urban Ecology group in Berkeley, California ( Roseland 1997). Kenworthy (2006) noted “Making existing cities and new urban development more ecologically based and liveable is an urgent priority in the global push for sustainability.” Ng and Hills (2003) argued that much research had focused on ranking world cities with respect to their economic health, but little work had addressed the comparative sustainability of these same cities, although more recently such comparisons are starting to be undertaken (e.g. (2014).Īlthough the interactions are complex and there is a need for more research, it seems that environmentally sensitive urban design can have a positive impact on human health ( Jackson 2003 Northridge et al. Given this treatment situation perhaps it is not surprising that the diarrhoea burden in Southeast Asia, as reflected by mortality and disability-adjusted life years (DALYS), is second behind sub-Saharan Africa in the regional analysis recently conducted by Pruss-Ustun et al. (2006) reported that 95% wastewater from Asian cities is discharged directly into receiving waters without any treatment. (2006) mark similar challenges for megacities globally. (2000) observed that explosive urban expansion throughout Asia has resulted in serious environmental problems, including air and water quality issues, and inadequate infrastructure Varis, Biswas et al. More sustainable, eco-friendly low impact development technologies should be considered in addition to hard engineering to reduce surface flooding. Increased pump capacity at the existing stations would reduce, but not eliminate, local surface flooding. Impacts of infilling on the large peri-urban community living on the wetland and to other ecosystem services were not assessed. The alternative of activated sludge treatment is shown to be costly and energy intensive. Urban expansion is placing increasing pressure on these wetlands and PCSWMM results showed that infilling of the largest wetland by up to 22% could have a negative impact on treatment, but the system still would function. Currently wastewater in Phnom Penh is treated effectively using sustainable, naturally occurring wetlands. Specifically, a personal computer (PC) version of the Stormwater Management Model (PCSWMM) was used to explore different wastewater treatment and urban flood management scenarios for Phnom Penh, Cambodia. To this end, we illustrate the application of a dynamic water resource model which can complement an index analysis.
Often, system sustainability and resilience are assessed using a simple index approach, which can be helpful in measuring changes over time or in a comparative evaluation of cities, but is less helpful in guiding specific policy and design decisions.

Hydrology, Drainage Analysis, Flood Studies, and Complex Stormwater Litigation for Atlanta and the South East - RE: PC SWMM vs.Eco-city philosophy and urban sustainability have been increasingly incorporated into planning and policy making. I have no experience with PC-SWMM, so I can't offer a point of comparison, but if you need to tap the brain of someone who's done quite a bit of XP modeling sometime later in the project, shoot me an email. Their graphing module was bought from some third party, and is terrible, and buggy, and doesn't give you the basic sorts of options that anyone who's ever had a Technical Communication class demands. In order to get any sort of graph that was remotely worthy of including in a report we always had to export node or link data to a text file, import to Excel, and do our own graphs by hand.
The two major drawbacks I see with XP are the cost, which is exorbitant, and the data presentation, which is generally horrid.
Can't answer either, but I've been an XP-SWMM user for most of the last decade, and I can say that XP-SWMM stability issues have gone away, provided you're not working with a model that's been "upgraded" through three or four versions, or has been subject to a lot of data imports from nefarious sources.
