This toolkit provides methodologies for a water utility to develop three documents that are essential to improve its climate resilience: a vulnerability assessment, a climate-resilient business plan, and an emergency response plan.
The current edition of the tool, by its intent and design, focuses on climate vulnerability and risk assessment of the utility’s water resources
The U.S. Climate Resilience Toolkit is a website designed to help people find and use tools, information, and subject matter expertise to build climate resilience. The Toolkit offers information from all across the U.S. federal government in one easy-to-use location.
Conduct a drinking water or wastewater utility risk assessment:
Vulnerability Self-Assessment Tool – Web Enabled (VSAT Web) 2.0 – is a user-friendly tool that can help drinking water and wastewater utilities of all sizes to conduct a risk and resilience assessment.
A greenhouse gas (GHG) calculator tool (Biosolids Emissions Assessment Model, BEAM) was developed for the Canadian Council of Ministers of the Environment to allow municipalities to estimate GHG emissions from biosolids management. The tool was developed using data from peer-reviewed literature and municipalities. GHG emissions from biosolids processing through ﬁnal end use/disposal were modeled. Emissions from nine existing programs in Canada were estimated using the model. The program that involved dewatering followed by combustion resulted in the highest GHG emissions (Mg CO2e 100 Mg-1 biosolids (dry wt.). The programs that had digestion followed by land application resulted in the lowest emissions (-26 and -23 Mg CO2 e100 Mg-1 biosolids (drywt.). Transportation had relatively minor effects on overall emissions. The greatest areas of uncertainty in the model include N2O emissions from land application and biosolids processing. The model suggests that targeted use of biosolids and optimizing processes to avoid CH4 and N2O emissions can result in signiﬁcant GHG savings.
The Effective Utility Management: A Primer for Water and Wastewater Utilities (“Primer”) is designed to help water and wastewater utility managers make informed decisions and practical, systematic changes to achieve excellence in utility performance in the face of everyday challenges and long-term needs for the utility and the community it serves. This document distills the expertise and experience of utility leaders into a framework intended to help utilities identify and address their most pressing needs through an incremental, continual improvement management approach.
The results show that the variables with a significant influence on efficiency are the chemical oxygen demand concentration; plant capacity; rate of used capacity, which positively affects efficiency; weight of industrial customers, which exerts a negative impact; and aeration system, with a negative impact for turbines. This article suggests the adoption of an effective control tool to monitor the costs, drivers and energy expenditure of water utilities.
The document is a guideline and tool for water utilities to evaluate, identify and implement measures for reducing the energy consumption in their treatment systems.
