“…End-use models allow residential water use to be split into separate water end-use components (Scheepers and Jacobs, 2014). Indoor water use has been widely modelled (Blokker et al, 2010), but outdoor use is much more variable and harder to model accurately, although models for estimating outdoor use are available (Jacobs and Haarhoff, 2004;DeOreo et al, 2011;Makwiza et al, 2015). Outdoor water use, mainly garden irrigation, is estimated to contribute approximately 40-60% to the AADD of GC homes, with a resulting seasonal water use pattern (Du Plessis and Jacobs, 2014).…”

Gated communities (hereafter GCs) are popular in many countries, including South Africa, because added security and lifestyle improvements are offered relative to homes built on freestanding properties. One of the key factors for the popularity of GCs is the availability of amenities to support the demands of the residents, such as gymnasia, walkways, golf courses, play parks and polo fields. Further benefits include the improved management of infrastructure such as telecommunication services, roads, water, sewer, electrical and stormwater assets. GCs are often governed by trustees or homeowners' associations, responsible for the operation and the maintenance functions of the infrastructure, as well as implementing and adhering to legislation that pertains to the GC. As part of this study, the monthly water-use records of 2 888 GCs in 3 different South African cities were analysed. Water use was evaluated for each GC as a whole, and also per household in each case. The average number of homes per GC was 33 households/GC, with the smallest GC in the study sample containing 3 houses and the largest 524 houses. One of the study sites was in the winter rainfall region, while 2 sites were in the summer rainfall region. The average annual water use of individual households in each GC was plotted against current guidelines and was found to be relatively low. The average annual daily demands of all properties in the winter rainfall region was 0.63 kL/d, compared to 0.66 kL/d and 0.49 kL/d for the two study sites in the summer rainfall region. The results highlighted peculiarities in the water use of GCs that have not been reported on before, in particular the relatively low water use and the differences between GC homes' water use in the various rainfall regions.

“…Sub-Saharan Africa is plagued with limited access to domestic water (WHO 2017), and when coupled with climate change, may potentially stress water supply facilities, making the region increasingly vulnerable to the impacts of water scarcity (Makwiza et al 2015;Klassert et al 2018). The challenges facing the region include increasing population and urbanisation, poor water network coverage, leakages, and poor cost recovery (Balogun et al 2017), bad governance and infrastructural deficit (Adaku 2016), high intermittency and low supplies (Karnib 2015;Loubser et al 2021), poor delivery infrastructure, increasing pressure on the demand for water (Purshouse et al 2017), and poverty and the inability to pay for a connection and water service (Nganyanyuka et al 2014;Bisung et al 2015).…”

Access to domestic water supply is a big challenge to many households in developing countries, as a large number of households do not have access to municipal water sources. The purpose of this study is to investigate the nature of access and characteristics of water sources and their impact on the choice and usage of water by providing empirical and statistical evidence. A survey of 1,300 households was conducted across six major cities in Southwest Nigeria, using structured questionnaires, field surveys, personal interviews, and observations. The data obtained were analysed using SPSS 27 for descriptive statistics and characterised using enhancement-based strategies. The result showed that access to pipe water was 5%, 66% used private wells and boreholes, and 29% used off-site water sources. The study discovered that 15 different water sources with unique attributes were consumed. The daily consumption ranged between 301 and 361 and 1,153 and 1,421 litres per household (L/hh/d) for those using off-site and on-site water sources, respectively. This study provides new insights with empirical evidence. As such, there is a need to re-evaluate the present water supply policy implementation, funding approach, and level of coverage. Additional policies that support and fund decentralised water projects, without compromising on water quality, should be provided, since they are more accessible to the people.
