Public-Private Partnerships & Water

Given the urgent need to address aging water infrastructure across the United States, public-private partnerships, or PPPs, offer a possible solution. The ongoing discussion of PPPs’ potential includes an overview of 2013’s PPP-related developments by Michael Deane, Executive Director of the National Association of Water Companies, for The Huffington Post and an article by Giulio Boccaletti, Managing Director of Global Water for The Nature Conservancy, in The Guardian that takes a look at financing solutions for natural infrastructure.

Earlier this year, ASLA’s Government Affairs Manager, Mark Cason, observed a roundtable discussion of PPPs focused on water supply and treatments. The roundtable, hosted by the House Transportation and Infrastructure Committee, addressed the challenges municipalities face in operating, maintaining, and financing their water and waste water systems. Panelists also outlined the substantial federal and state investments needed to address all of the demands, especially as the original infrastructure reaches the end of its life cycle.

Synthetic Surface Sport Fields for Water Conservation & Long-Term Carbon Footprint Reduction

Sustainability experts typically agree on two measures for high performance sport fields: total fresh water saved, and net reduction in carbon footprint with all factors considered over the life cycle of the sports field.

So, what are the water conservation features for synthetic surface sport fields, and what other factors determine how green your sport field grass is? Before outlining features and factors to consider, we’ll take a look at a project at Western Washington University that is an example of a high performance sports field design with synthetic surface fields that are truly greener, including high performance for water conservation.

“If the design and specification is done right, all-weather synthetic surface fields including adequate subsurface drainage will minimize runoff. This is especially important at our Western Washington University (WWU) campus in Bellingham, Washington in the Pacific Northwest,” says Linda Beckman, Vice President for Student Affairs at WWU. “Ideally, synthetic surface will be selected for high recycled content, as a low-VOC product for air quality concerns, and will be maintained properly. Upfront, we decided to fund proper maintenance and also decided it will be recycled when it nears the end of its life, and to select a consultant who understands the full picture of environmental performance from products and systems. Our Pacific Northwest strong environmental commitment is met by using the sport field surface system we approved—we did it right and we did it green.”

Annual Meeting Highlights from Water Conservation

Flying home from 2013 ASLA Annual Meeting in Boston,  my flight back to Seattle encountered typical Midwest winter weather in the Great Lakes area, perhaps the only large region in the US without an existential threat to their fresh water supply. My hours traveling gave me time to reflect on the Annual Meeting’s over a dozen sessions related to water conservation. Three education sessions plus our Water Conservation PPN Meeting are featured below, all of which reflect how the water conservation focus at the 2012 Phoenix conference remained high on the national agenda at the Boston 2013 conference. Below, you’ll find my thoughts on a project in San Diego, biophilic design, plus discussion among a dozen  leading water conservation professionals.

Whether you attended the Annual Meeting or could not make the trip to Boston this year, I’m happy to share a few highlights. Each session title is a link, providing more information about the presenters or subject of that session, so please take a look!

Investing in Natural Infrastructure

From meeting increasing demand with aging water infrastructure to planning for extreme weather events, the challenges of managing water wisely are growing ever more numerous and complex.

The World Resources Institute recently released a report, Natural Infrastructure: Investing in Forested Landscapes for Source Water Protection in the United States, on how forests, wetlands, and floodplains can play a central role in avoiding and alleviating water-related crises. Drawing on the expertise of more than 50 authors, the report describes in detail how currently underutilized natural infrastructure might be harnessed to improve water management practices, and the many opportunities there are for doing so. The case studies included range from forest-based efforts in Maine, Oregon, North Carolina, Colorado, and Washington to a stormwater control program on Staten Island, New York.

The report is intended to be “a call to action for water utility staff and land managers alike to bring natural infrastructure into focus in their institutions, with this guide as a foundation from which businesses and municipalities can innovate in the face of a growing water crisis.” By investing in natural infrastructure now, water managers can both reduce the costs of water management and help to ensure access to clean water for generations to come.

A recent interdisciplinary design competition, Infill Philadelphia: Soak it Up!, encouraged a wide array of professionals to propose innovative solutions addressing Philadelphia’s aging combined sewer system. According to the Philadelphia Water Department (PWD), about 60% of the city still operates on combined sewer. Through the city’s efforts to become the greenest city in America by 2015, Philadelphia has become a national leader in stormwater management planning and policy by creating Green City, Clean Waters, a progressive 25-year stormwater management plan focusing on using green stormwater infrastructure to reduce pollutants in local waterways.

Nevada DOT responds to water and budget limitations for landscapes.

Embracing soil as an important player in water conservation, the ASLA Water Conservation Professional Practice Network spotlights the Nevada Department of Transportation (NDOT) Landscape Architecture, where they have adopted a standard policy of “no irrigation” for southern Nevada freeway landscape enhancements.  To respond to that challenge, designers are utilizing porous inorganic amendments as an aid to increase plant-available water in the soil in a region where rainwater harvesting challenges are unique.

A Case for Cool pavement Systems

Cool pavement systems as a hot mix asphalt alternative is encouraged by state legislation in California.

The Water Conservation PPN is highlighting two ways cool pavement technology save water.  First, reducing paving temperature reduces water evaporation from soil adjacent to paving. Also, plants in close proximity to pavement lose water quickly, when compared to plants adjacent to cool pavements. In addition to positive air quality impacts (carbon, VOC’s, temperature, etc.), water conservation is a good reason to look at new resin based paving technology. This will be explored here through a case study of a project in Northern California: Lake Merritt located in the middle of Oakland, CA.
