Water Infrastructure - 0 views

  •  
    DRIVER-WATER-SCARCITY-INFRASTRUCTURE-MATERIALS The North American drinking water infrastructure network spans an estimated 1 million miles, more than four times longer than the National Highway System, and that doesn't even take wastewater pipes into account. Much of the water infrastructure in the United States will need to be replaced in the next three decades. A large portion of water pipes was installed during three periods, and they will all need to be replaced in the next 25 years. Consider the following The oldest cast iron pipes laid in the late 1800s usually last 120 years; Pipes laid in 1920s must be replaced after 100 years; Pipes from the post-World War II boom wear out after 75 years. According to a 2012 report done by the American Water Works Association, the cost estimate to replace the old pipes is approximately $1 trillion over the next 25 years. The longer our water infrastructure is out of sight and out of mind, the closer we are to a serious national situation that will require immediate and dramatic funding. The cost of water infrastructure replacement far exceeds the financial capabilities of local water utilities and requires a strong commitment from not only utilities but rate-payers and government as well.

Pipe Market Turns to New Materials to Address Aging Water Infrastructure - Water Financ... - 0 views

  •  
    DRIVER-MATERIALS-INFRASTRUCTURE Municipal pipe market spending makes up 30 percent of overall utility CAPEX for water infrastructure. In part, to address aging pipes, bursts, and other leakage management issues, the pipe market is turning to new materials (plastic) and new technologies (trenchless). More than $234 billion (USD) of capital expenditures (CAPEX) are forecasted over the next decade to address aging municipal water and wastewater pipe network infrastructure, according to Bluefield's forecasts. Precipitated by decades of underinvestment, municipal utilities are under increasing pressure to address deteriorating linear assets at a faster pace. Water losses through leaks for U.S. utilities average 15 percent annually, with some cities, towns, and communities losing more than half of all water pumped and treated for distribution to customers. As a result, rehabilitation of existing pipes is the fastest growing spend category, increasing annually from $253 million in 2019 to $576 million by 2028. Network expansions, particularly in high population growth across the sunbelt states (e.g. Texas and Arizona), will drive the lion's share of spending on new build.

Aging Water Infrastructure is a Serious Threat to Water Quality Throughout th... - 0 views

  •  
    In a 2018 survey and assessment, the Environmental Protection Agency (EPA) found that drinking water infrastructure alone needed nearly $500 billion in maintenance and improvements over the next 20 years. This figure does not even include the cost of addressing lead service line issues and the need to add additional capacity in growing communities. Coupled with the need to replace aging pipes, water utilities are facing the need to prepare for the impacts of climate change on their operations. Recent drought events suggest that water supplies in many states will face serious challenges just to keep operating normally.

    DRIVERS-TREATMENT-TTHM-POLLUTION-SCARCITY-FUNDING Disinfection by-products (DBP) are a class of chemical by-products also referred to as trihalomethanes (THMs), formed when chlorine or bromine interacts with the natural organic materials found in water. DBPs also include other formed products, such as haloacetic acids, haloacetonitriles, haloketones, and chlorophenols. The composition and levels of specific DBPs are determined by water quality, water treatment conditions, and disinfectant type (IPCS, 2000). Primary sources of DBPs are chlorinated drinking water and recreational water bodies, such as swimming pools. In drinking water, trichloromethane is the predominant DBP, usually found at much higher levels than bromodichloromethane; tribromomethane is the least abundant (Krasner et al., 1989). DBPs are volatile at room temperature and can be detected in ambient air during activities such as showering, bathing, dishwashing, and swimming (Backer, et al., 2000; Gordon et al., 2006). Trichloromethane has industrial applications and is used to produce refrigerants and feedstock. It may be released into the environment where chlorine-based chemicals are used for bleaching and disinfecting processes or disposed at hazardous waste sites (IPCS, 2004; LaRegina, et al. 1986). Tribromomethane has limited industrial uses, mainly in geological assaying, electronics manufacturing, and as a solvent in laboratory analyses (ATSDR, 2005). DBPs tend not to bioaccumulate in aquatic organisms or persist in open or surface waters or soils, but they can remain in water within closed pipe systems. Workplace exposure may occur during the production of trichloromethane or tribromomethane, or in workplaces where DBPs may be generated, such as pulp or paper manufacturing, swimming pools, and water treatment plants (IPCS, 2004).

Material Scientists from NUST MISIS Create a New Corrosion-resistant Steel for Oil Pipe... - 0 views

  •  
    he new Russian steel called Severkor for oil pipelines has been created by materials scientists at NUST MISIS in order to reduce the environmental risks of oil production and increase its efficiency due to increased corrosion resistance. A year ago, the first test pipe from the developed steel was installed at the Kokuysky oil and gas field in the Perm Krai territory in Russia. In the fall of 2019, Lukoil company has presented an expert opinion confirming Severkor's unique resistance to the aggressive environment of crude oil and salt solutions.

Aging Water Infrastructure | Science Inventory | US EPA - 0 views

  •  
    The Aging Water Infrastructure (AWI) research program is part of EPA's larger effort called the Sustainable Water Infrastructure (SI) initiative. The SI initiative brings together drinking water and wastewater utility managers; trade associations; local watershed protection organizations; and federal, state, and local officials to ensure that all components of our nation's water infrastructure….drinking water treatment plants, drinking water distribution lines, sewer lines, and storage facilities….meet future needs. The AWI research program supports the four priority areas of the SI initiative's strategy: (1) Better Management - moving beyond compliance to sustainability and improved performance, (2) Full-cost Pricing - helping utilities to recognize the full cost of providing service over the long term, (3) Water Efficiency - promoting water efficiency in the residential and commercial sectors, (4) Watershed Approach - integrating watershed management principles and tools into utility planning and management practices. The driving force behind the SI initiative and the AWI research program is the "Clean Water and Drinking Water Infrastructure Gap Analysis." In this report, EPA estimated that if operation, maintenance, and capital investment remain at current levels, the potential funding shortage for drinking water and wastewater infrastructure could exceed $500 billion by 2020.

    "Lead leached from old pipes after the city began using the Flint River in 2014 without adding corrosion-control chemicals. Flint returned in 2015 to Detroit's water system.(...)Residents in Flint whose homes still may need new water lines due to lead contamination may have a new benefactor in Elon Musk. The tech billionaire caused a stir on Twitter Wednesday, tweeting Wednesday that he was committing to "fund fixing the water in any house" with contamination above federal levels."

New report offers grim details on underinvestment in U.S. water infrastructure - Water ... - 0 views

  •  
    According to the new report released last week by the American Society of Civil Engineers (ASCE) and Value of Water Campaign, the United States is underinvesting in its drinking water and wastewater systems, putting American households and the economy at risk. The report, "The Economic Benefits of Investing in Water Infrastructure: How a Failure to Act Would Affect the U.S. Economy Recovery," finds that as water infrastructure deteriorates and service disruptions increase, annual costs to American households due to water and wastewater failures will be seven times higher in 20 years than they are today -from $2 billion in 2019 to $14 billion by 2039.

Investing in Aging Water Infrastructure | ASCE's 2021 Infrastructure Report Card - 0 views

  •  
    When we modeled what the next two decades would look like if we continued current underinvestment trends, we found that no industry is immune to water disruptions. The most water-reliant businesses will spend $250 billion in 2039 on costs related to water service disruptions. Less reliable water service would make industries less efficient and profitable, and the consequences would ripple across the entire economy, leading to more than $4.5 trillion in lost business sales, a $2.9 trillion decline in the gross domestic product (GDP), and 636,000 fewer jobs. Individual households and communities would also endure the consequences of underinvestment as more frequent and extreme weather inflict shutdowns, and street flooding deteriorating and rupturing water infrastructure. Without proper infrastructure investment, there will be greater costs to US households. At the current rate, costs will be seven times higher in 20 years than they are today, totaling $14 billion in 2039.
