There is considerable interest by utilities to establish carbon footprints of wastewater treatment plants (WWTPs) with respect to greenhouse gas emissions, energy usage, energy production, and carbon credits for wastewater treatment. The methodologies and methods are at an early stage and have a great deal of uncertainty and variability. In this paper, a systematic and summary methodology to determine the carbon footprint of a WWTP including at operating, construction, process sinks and emitters’ levels has been presented. The paper also presents a case study based on this systematic summary methodology to illustrate the tools used. Source: WEFTEC 2009 Proceedings

Distributed water management describes integrated planning, design, and management using system infrastructure at various scales, based on an equitable approach that considers suitability and sustainability. This paper, based on research supported by the Water Environment Research Foundation, introduces distributed management in the context of sustainability, provides examples of where distributed approaches are being used to advance sustainability at the community level, and suggests principles and provides tools that practitioners can use to maximize value. Case studies that illustrate distributed management approaches include onsite reuse systems driven primarily by green building and sustainable design and managed decentralized systems, including either individual onsite systems, cluster systems, or a combination thereof. Examples include situations where traditional municipal utilities are incorporating distributed infrastructure approaches such as managed cluster systems, wastewater mining, and satellite reuse facilities.

Wastewater reclamation produces a recycled product. The traditional linear approach to water resource management is increasingly proving to be unsustainable due to water stress being placed on urban water management. By nature reclamation is a process that reduces the energy consumed in the water cycle and therefore is the cornerstone of sustainability in the management of water resources. The value of reclaimed water includes the embodied energy that is reclaimed from the water cycle. This paper provides the methodology for establishing a value chain in determining the economic benefit of water reclamation and identifies ways for communities to take the first steps of this resource as a strategy to reduce greenhouse gases, carbon footprint and a sustainable principle of water portfolio management. Until recently, the embodied energy in wastewater reclamation has been a hidden value not considered in a full life cycle analysis9. The value of reclaimed water includes the embodied energy that is reclaimed from the water cycle. When embodied energy in reclaimed water is accounted for over a 50 year life cycle term, at 12 cents per kilowatt-hour and not including interest it has a value between $8.5 to $14.8 million dollars per million gallons. The capital cost and operating cost for the reclaimed water infrastructure is a minimal cost when compared with the overwhelming operational energy recovery savings. If you want to truly be sustainable wastewater reclamation is the cornerstone that provides the greatest environmental benefit. Water conservation, while an important component of a sustainable water resources management plan does not provide the same value chain impact in terms of reducing the carbon footprint and does not reclaim the energy already embodied in the water product.
