Integrating the planning of green spaces and sustainable drainage systems
… In some established urban areas the existing drainage infrastructure is unable to cope with the volume of surface runoff and flooding events are more frequent, therefore new approaches to create more space for water within developments are required. This research was conceived in that context. …

Century City as a case study for Sustainable Drainage Systems (SuDS) in South Africa
South Africa's developing cities are experiencing rapid urbanisation, particularly in the major metropolises. Infrastructural development is a prominent component of the South African economy, and has been allocated hundreds of billions of Rands by the budgetary council in the present political …

Managing nutrient flows into the Zandvlei Estuary, Cape Town using Sustainable Drainage Systems (SuDS)
… which are largely comprised of conventional drainage systems which carry stormwater pollutants into the watercourses that then drain into the estuary. Of the many pollutants that flow into the estuary, elevated nutrient levels (specifically phosphorus and nitrogen) are a major concern because …

Linking sustainable drainage systems (SuDS) together with ecosystem services and disservices : new connections in urban ecology
… affect human and wildlife well-being negatively. Sustainable drainage systems (SuDS) have the potential to mitigate these effects and also provide additional amenity and biodiversity benefits. However, the current SuDS approach is site-specific and technically focused, hence, failing to generate …

Managing the Water Quality of the Zandvlei Estuary using Sustainable Drainage Systems in the Diep Catchment
… volumes and runoff rates in the stormwater drainage systems. In South Africa, stormwater drainage systems conventionally channel everything they collect into receiving water bodies without significant treatment or intervention to remove harmful substances. Sustainable Drainage Systems (SuDS) …

Quantifying stormwater pollutants and the efficacy of sustainable drainage systems on the R300 highway, Cape Town
… natural environment. In particular, highway drainage presents a high risk of pollution when compared to other urban land use areas (Ellis et al., 2012); introducing heavy metals, suspended solids and hydrocarbons to urban waterways. This research investigated runoff from the R300 highway, …

Rapid decision support tool based on novel ecosystem service variables for retrofitting sustainable drainage systems in the presence of trees
… support tool for different professions such as drainageengineers and urban planners, which is useful for a quick assessment of the potential ofecosystem services when retrofitting sustainable drainage systems (SUDS) in urban areasTherefore the aim is to develop adecision support tool for …

Reduction of pollution levels in the Chatty River through Sustainable Drainage Systems: A case study of the Bethelsdorp River sub-catchment
… water quality through the possible inclusion of Sustainable Drainage Systems (SuDS). The Chatty River's physical, nutrient, and microbiological characteristics were assessed through water quality sampling and historical data review to identify pollutant hotspots. The high mean dissolved inorganic …

An investigation of the treatment efficacy of permeable pavements for water quality performance in South Africa
… of ecological degradation of urban streams. Sustainable Drainage Systems (SuDS) attempt to address stormwater impacts by flow attenuation and pollutant treatment, simultaneously providing amenities such as water for use in irrigation or other suitable uses. Permeable pavements are a form of …

Improving the design, construction, and maintenance of Permeable Interlocking Concrete Pavement (PICP) in South Africa
… These may be mitigated by measures such as Sustainable Drainage Systems (SuDS) that seek to mimic the natural hydrology of a site. Permeable Pavement Systems (PPS) are a popular SuDS source control measure, with Permeable Interlocking Concrete Pavements (PICP) being the most common. PICP …

Evaluation of flow models and pollutant retention isotherms for their application to rain garden bioretention
… flow on heavy metal retention in rain garden systems under typical English climatic conditions. The findings of these experiments indicated that although macropore flow did not impact the hydraulic performance of the columns, retention of the most mobile of heavy metals, copper, was decreased …

Using urban facilities management principles to promote sustainable water management in informal settlements in South Africa
… Facilities Management (UFM) in the promotion of sustainable water management practices in informal settlements in South Africa. The rationale for the study is that with the rapid increase in urban populations and the number of people living in informal settlements, there is an increased need for …

Review and gap analysis of Water Sensitive Urban Design (WSUD) in Windhoek, Namibia
… as Low-Impact Development (LID), in the UK as Sustainable Drainage Systems (SuDS), and in New Zealand as Low-Impact Urban Design and Development (LIUDD). Namibia is situated along the south-west coast of Africa and is considered the driest country in sub-Saharan Africa. It is characterised by a …

The social dimension of stormwater management practices including sustainable urban drainage systems and river management options
… the fact that there is a general preference for sustainable urban water management and for river restoration schemes compared with more conventional, ‘hard engineering’ approaches, such as culverting of rivers. This preference was expressed both by members of the public and by professionals …

The link between Permeable Interlocking Concrete Pavement (PICP) design and nutrient removal
… pre-development state unless mitigated through Sustainable Drainage Systems (SuDS). Permeable Pavement Systems (PPS), one of the source control options in SuDS suite, are able to control stormwater runoff and reduce the discharge of pollutants (Armitage et al., 2013). Urban runoff typically …
