MAD? Monitoring, analysis and decisionmaking – what we need to make sure alternative water sources are safe.

Many of these may be too expensive or not quite right for developing countries or routine use, but they are a good start to optimise from.

1001 South African Stories is a project that uses storytelling as a mechanism to connect South Africans.
Through oral history we explore South Africa’s troubled and complex history. More contemporary personal narratives help to unpack South Africa’s present.
The aim of the project is to contribute to a more cohesive and inclusive understanding of South Africa’s history.

Let’s Talk Regeneration is a multimedia campaign and web discussion series that supports the creation of a Long-Term Regenerative Plan for South Africa. It is an invitation to dream and a call to action, awakening the more beautiful world we all desire.
Let’s Talk Regeneration features conversations with a bunch of awesome Re-generators: activists, academics, artists, designers, elders, farmers, scientists, economists, nature custodians, youth, exploring a spectrum of questions, themes and solutions.
The series paints a picture of what a regenerative world looks and feels like, suggests a pathway towards this world through ecological design and some simple steps to take along the path.
Our aim is to stimulate discussion and action towards regeneration on an ecological, social and personal level; and to support the formation of a regenerative storytelling network.
Join us on this journey to the more beautiful world our hearts know is possible.
GARDENS ARE IMPORTANT
ALL green areas – whether planted landscapes, wild areas, or a road verge with weeds – contribute to the urban ecosystem. They are vital to our well-being: green areas produce air for us to breathe, they filter pollution, absorb storm water and reduce flooding, purify water and maintain a pleasant temperature. Without sufficient planted areas and infiltration – due to the many tarred and paved areas, and reflective surfaces – the city heats up. This is known as the urban heat island effect: pollution levels rise and our quality of life decreases. On summer days, especially when there is no wind, the raised temperature is already evident in the City Bowl, which is a few degrees hotter than the suburbs.
Gardens form an important part of the urban ecosystem and are not a luxury: they are a necessity. Green areas provide habitat for wildlife and are good for our well-being. Please do not feel guilty about gardening! We encourage anyone with access to alternative water sources, such as borehole or grey water, to use it responsibly to help maintain the urban ecosystem. Furthermore help spread awareness of its value and the importance of permeable surfaces for infiltration of rain. This will make a positive difference.
Some simple ways you can help preserve the urban ecosystem:

Trees reduce air pollution in the urban environment, absorb CO2 and shade roads to decrease heat sink aspects. (Clare Burgess)

Water sensitive design includes the use of fit-for-purpose water, and harvesting and/or storing water from various sources. In South Africa particularly we should reduce our dependence on surface water bodies (aka, dams). This presents an opportunity, but it also introduces a great amount of risk, particularly if these sources are more decentralised than what we are used to.
Our drinking water is treated at central locations before it is piped to our homes (if we are lucky to have piped water). That means that one central location manages this risk for us, and can afford the costs of accredited scientific analysis.
When we start looking at alternative sources of water, the analysis (and other) costs are carried by far less people and the relative cost of managing that risk increases.
To manage this risk in the urban environment, and help individuals manage this risk there are three complementary options:
What exists in terms of mapping water sources?
As far as we know, there is no visual map, but databases do exist:
Adequate treatment invariably involves a combination of these, and while treating water to potable, or drinking water quality, the technology is similar to treating dirty water to protect the environment (like what happens in sewage works or koi ponds)

Located at the northern point of the Cape Flats Aquifer (CFA) this site drains stormwater to recharge the aquifer sustainably, while providing an indigenous healing landscape for the Mitchells Plain Hospital.
The site is testament to adaptation by engineers and landscape architects to create a water sensitive landscape, beautifully.

How does it compare with the 17 Principles?
0 – Does not address this at all / unknown
1 – Potential to address this, but currently unaddressed
2 – The design addresses this, implementation can do more
3 – Integrated in the project, good implementation.
A. Regenerative Water Services:
A.1. Replenish Waterbodies and Their Ecosystems: 3. Stormwater recharge into aquifer.
A.2. Reduce the Amount of Water and Energy Used: 3. Waterwise indigenous vegetation.
A.3. Reuse, Recover, Recycle 3. Local rocks were re-used, plants were sourced and propagated from the site.
A.4. Use a Systemic Approach Integrated with Other Services: 3. Design incorporated sound engineering principles, and was appropriate to the healing landscape of the hospital.
A.5. Increase The Modularity of Systems and Ensure Multiple Options: 2. Multiple avenues for stormwater ingress as well as engineering required overflow grates.
Comment: What is the potential for the hospital’s operation to become more water sensitive?
B. Water Sensitive Urban Design:
B.1. Enable Regenerative Water Services: 3. Through the infiltration and the sandy underlying soil, the water is treated as it moves towards the aquifer.
B.2. Design Urban Spaces to Reduce Flood Risks 3. Reducing flood risk was central to this project’s design, through both the landscape architecture and the engineering ‘back-up’ infrastructure.
B.3. Enhance Liveability With Visible Water: 2. Being in a water scarce environment with high wind makes it hard to make water visible, along with concerns for safety.
B.4. Modify and Adapt Urban Materials to Minimise Environmental Impact: 2. Materials were sourced from site where possible for the landscape. Unknown about the actual building.
C. Basin Connected Cities:
C.1. Plan to Secure Water Resources and Mitigate Drought: 1. Drought mitigation through indigenous plants and aquifer recharge. Unknown site-use specific measures.
C.2. Protect the Quality of Water Resources: 0. Unknown.
C.3. Prepare for Extreme Events: 0. Unknown.
D. Water-Wise Communities:
D.1. Empowered Citizens: 0. unknown, is the local community and hospital management involved?
D.2. Professionals Aware of Water Co-Benefits: 0. Unknown.
D.3. Transdisciplinary Planning Teams: 2. The project addressed this, but continuing maintenance is uncertain.
D4. Policy Makers Enabling Water Wise Action: 0. Unknown. Has this project promoted policy change?
D.5. Leaders that Engage and Engender Trust: 0. Unknown.
