Challenges of Urban Water Infrastructure

Challenges of Urban Water Infrastructure

AT PRESENT, 80.7% OF the US population resides in urban areas (US Census Bureau 2012). Increased urbanization (paved areas and buildings) and urban population growth has exerted significant pressure on urban water demand and expansion of urban water infrastructure—i.e., potable water supplies, wastewater treatment and discharge, and urban stormwater runoff

Growing Pains

Growing Pains

Known for its involvement with banking and auto racing, Charlotte is one of the 10 fastest-growing cities in the US. The city’s 2014 estimated population is nearly 810,000.

“The Future Looks Smaller”

“The Future Looks Smaller”

As with many other cities that have combined sanitary and storm sewer systems, Chicago has a combined sewer overflow problem, with an average of more than 60 overflows a year. And, as many other cities are doing, it’s turning to green infrastructure to help solve the problem—infiltrating as much water

Variables for Energy-Efficient Roofs

Variables for Energy-Efficient Roofs

Roof material choice is one area of building envelope design where significant efficiency can be found. Energy-efficient roofs have come a long way in recent years. Cost savings can be realized, and service life can be greatly extended with careful selection of a modern energy efficient roof.

JRM CHEMICAL
JRM Chemical’s linear anionic polymers (PAM) are available in powders, emulsions, and tablets to reduce soil erosion and treat turbid water. They are also used as a tackifier with mulch and straw. Low application rates of 4 ppm or less will reduce turbidity in discharge water and reduce suspended particles

Rainwater Harvesting

Rainwater Harvesting

Although various forms of rainwater harvesting have been used for thousands of years, as an organized industry, it is still in its infancy. At present, no national standards are in place regulating its use, although various states and municipalities have begun promulgating laws concerning how rainwater may (or may not)

Stormwater Systems Benefit From Green Roofs

Stormwater Systems Benefit From Green Roofs

With their myriad benefits, green roofs are becoming increasingly incorporated into new and existing projects. The International Green Roofs and Walls Project Database lists 1,599 projects totaling 33,334,677 square feet, and the number is growing.

Green roofs—also known as vegetated or garden roofs—are key green infrastructure elements and are being increasingly

Compost: The Sustainable Solution

Compost: The Sustainable Solution

The use of recycled organics is one of our nation’s greatest assets, and we can utilize them to address several of society’s vexing challenges. The commercialization of composting as an economic method to manage organic (carbon-based) “wastes” got its rebirth in the late 1970s, and has grown from coast to
