An amazing resource posted on ASLA’s The Dirt (here) focuses on Design Guidelines for Urban Wetlands, specifically what shapes are optimal for performance. Using simulations and physical testing to investigate hydraulic performance the team from the Norman B. Leventhal Center for Advanced Urbanism (LCAU) at MIT. Led by Heidi Nepf, Alan Berger and Celina Balderas Guzman along with a team including Tyler Swingle, Waishan Qiu, Manoel Xavier, Samantha Cohen, and Jonah Susskind, the project aims to have a practice application in design guidance informed by research. From their site:js_plan_typical-01

“Although constructed wetlands and detention basins have been built for stormwater management for a long time, their design has been largely driven by hydrologic performance. Bringing together fluid dynamics, landscape architecture, and urban planning, this research project explored how these natural treatment systems can be designed as multi-functional urban infrastructure to manage flooding, improve water quality, enhance biodiversity, and create amenities in cities.”
Starting in the beginning by outlining ‘The Stormwater Imperative’, the above goal is explained in more depth, and issues with how we’ve tackled these problems are also discussed, such as civil-focused problem solving or lack of scalability, but also explore the potential for how, through intentional design, these systems “can create novel urban ecosystems that offer recreation, aesthetic, and ecological benefits.” (1)

The evolution that has resulted in destruction of wetlands through urbanization, coupled with deficient infrastructure leads to issues like flooding, water pollution due to the loss of the natural holding and filtering capacity of these systems and the increased flows. However, as pointed out by the authors, this can be an opportunity, as constructed wetlands “can partially restore some lost ecosystem services, especially in locations where wetlands do not currently exist.” (5)

The modeled flow patterns are also interesting, showing the differentiation from fast, regular, slow flows, along with any Eddy’s that were shown in dye testing using the flumes.

This is why the price of water needs to go up substantially

Sungula Nkabinde on Moneyweb Today :

 

“Proposed revisions to South Africa’s water pricing strategy are as broad as they are complex, but what is clear is that water will become significantly more expensive in the future.

The Department of Water and Sanitation (DWAS) has gazetted a draft of the revised water pricing strategy, which outlines a theoretical framework that would engender a fully functioning water eco system. The 2013 document has led the discussion on how South Africa can reduce the financial burden on municipalities, which are required by law to provide water to those who cannot afford to pay for it, by transferring the full cost of delivering water services onto users. They will  incur a raft of charges that will see water pricing reflect the level of water scarcity in the country.

Domestic and commercial users will pay for charges related to planning, capital costs, operation and maintenance, depreciation, and future infrastructure build on government water schemes. A new polluter pays principle will also be imposed to ensure users discharging water containing waste into a water resource or onto land pay an additional amount.

According to the DWAS, South Africa ranks as one of the 30 driest countries in the world with an average rainfall of about 40% less than the annual world average rainfall.

Even though the implications could potentially be disastrous for an already struggling economy, the consequences of not the addressing the water security problem could be worse. The revised pricing strategy seeks to incentivise more efficient use of water, and ensure the much needed upgrade to the country’s water infrastructure is properly funded.

Municipalities struggling with poor billing systems, significant water leakage and high rates of non-revenue water (water provided for which no income is received) are a big part of the reason why there significant capital is required to resolve the water crisis in South Africa.

Sanlam economist Arthur Kamp says it’s not possible to give a definitive, or even a ball-park figure of how much the cost of water is going to increase by, saying price structures are going to be quite complicated because it is going to be a hybrid model. There will be a wide range of charges that will be determined on a national level, other times sectoral level.

Says Kamp: “What (the draft revised water pricing strategy) does is it gives one the flavour of what they’re trying to achieve. There is a lot of infrastructure coming and we can’t afford it so the user is going to pay. And I don’t think anybody is going to dispute that water is a scarce resource and that tariffs need to reflect that”.

Sasaki Associates, with RDG and AES, Wins Water Works Parkitecture Competition

From Bustler :  a review of a project reintegrating people, water and nature which is both educational and engaging – funky use of fashionable stand up paddle boards and  representation which is viewed as if we are navigating the brochure and looking out on the scene must have played apart in winning over the judges:

Des Moines Water Works, working in partnership with Iowa State University Department of Landscape Architecture, recently announced that Sasaki Associates, with RDG Planning & Design and Applied Ecological Services (AES), is the winning team of the Water Works Parkitecture Competition.

The design team and Des Moines Water Works will begin a concept validation process which will address specific issues and include public outreach. It is expected that a majority of the funds for implementation of the vision plan will be obtained through private fundraising and will not be borne by water rate payers.

Throughout the design process, the design team interviewed citizens, community leaders, focus groups, and stakeholders, and will continue engaging the public throughout the master plan and implementation process of the park

The future of development across the western United States is intricately linked to the
availability of water. A precious, but often overlooked and misunderstood resource, water
impacts policy, the environment, and economics. Addressing these issues, a team of scientists
and researchers from UCLA’s Institute of the Environment and Sustainability will present
findings, brief attendees, and answer questions on water, energy, climate change, and strategic
design opportunities for a water-smart future. “We are delighted that UCLA’s IoES is joining us in
this effort” said Peter Arnold, architect and ALI co-director. “Design without science is folly.”

Presentation topics include: the limitations posed by energy-intensive water delivery systems;
projected impacts of climate change on western water resources; myths and realities of
localized stormwater management, including case studies; and the challenges, both regional and
global, of managing water in an urbanized world.

Architectures of Hybrid Migrations (via Free Association Design (F.A.D.))

I wonder how this type of advanced engineering science meshes with the worlds of migration and how the determination of which fish to allow to migrate and which to reject is not modifying the system that it is trying to preserve?

Architectures of Hybrid Migrations Although very likely not submitted to this year's Animal Architecture Awards, the design for the "Selective Water Withdrawal Tower" on The Deschutes River could have been a candidate for the prize, or at minimum, a poignant contribution to forums discussing "the myriad issues arising from the complex interactions between animals and human society", and how such interactions tend to co-shape one another. The Round Butte Selective Water Withdrawal … Read More

What’s in the Water?

Issues of how we manage our water and what goes into it have been a primary the reason for urban planning and city design  since Roman times,  read about  it in Sextus Julius Frotinus’s  ‘De Aquis urbis Romae’ – in it he laments  about illegal  drawings from the roman water system “The public water courses are actually brought to a standstill by private citizens just to water their gardens.”  Tehre was a more insidious and invisible enemy lurking within the system – Roman lead pipes are conjectured to have lead to the fall of Rome some centuries later. We don’t seem to have got much better at it – like all regulation based processes, its what they are based on and  it’s not only having the laws  – but how they are enforced – leading to the the idea that any design that relies on enforcement is inherently flawed, the big question in all civic and environmental regulation is how  do we obtain the active participation of the public whose interest is supposedly being served and how do we use that public policing to curtail the actions of those whose self interest is put above the civic good?

In this articles from METROPOLIS MAG.COM By Becca Harsch and Stephanie Stone soem of these issues are raised in relation to water quality,

The Kansas River, photographed in Lawrence, Kansas.

“A glance at the 2010 Water Quality Report reveals a plethora of contaminants in our local water supply. From atrazine – a type of herbicide – to arsenic, the contents of the report are surprising but not unique. We are residents of Lawrence, Kansas, and our water comes from the Kansas River, commonly known as the Kaw. The Kaw is the world’s longest prairie river, according to Friends of the Kaw, a grassroots organization that works to protect and preserve the river. The fact that the Kansas River supplies water for 600,000 Kansas residents emphasizes the idea that everyone is downstream from somewhere. But we are not unique: a quick look at your municipality’s water report will likely reveal much of the same information.”

World Water Day 2011 – Cape Town to host main event

Cape Town will be busy again in March hosting the main conference event UN Water’s World Water Day from 20 – 22nd March 2011 at the Cape Town International Conference Center.

Cape Town with its Mediterranean climate having wet Winters and dry Summers as can be seen now around the city how the landscape becomes dry and brown and with past water shortages all but forgotten it is important to keep in mind the essential nature of water to life and how many people do not have access to safe clean and pure drinking water while some of thoughtlessly use waste potable water on gardens and car washing. Finding ways to conserve and rethink out use of water and how to recycle and reuse it as many times as possible , while still allowing it to flow through the natural system without polluting that system further downstream from us, is  one of the many water related challenges which will be focused on at this conference and all over the world on March 22nd which is WORLD WATER DAY 2011
