Esta Guía facilita la toma de decisiones preliminares sobre el proceso más apropiado para tratar las aguas residuales municipales. Esta Guía de selección de procesos se diseñó para respaldar la evaluación de proyectos de saneamiento desde un enfoque de mitigación del cambio climático que propicie el desarrollo sostenible, aunque sin descuidar los criterios de cumplimiento con las regulaciones ambientales mexicanas y la viabilidad técnica o económica.
Este folleto descriptivo y su libro complementario MS Excel © son herramientas de apoyo para evaluar las posibilidades de los trenes de tratamiento en las plantas de tratamiento de aguas residuales municipales. Los procesos recomendados y sus combinaciones reducen las emisiones gaseosas al máximo y muestran la viabilidad técnico-económica.
This Drought Guide can be used to anticipate and prepare for the consequences of drought on infrastructure services. This guide was developed through the interagency National Drought Resilience Partnership (NDRP). It directs users to the National Integrated Drought Information System (NIDIS) (drought.gov) and other agencies’ information and decision tools.
Climate change presents several challenges to drinking water and wastewater utilities, including increased frequency and duration of droughts, floods associated with intense precipitation events and coastal storms, degraded water quality, wildfires and coastal erosion and subsequent changes in demand for services. While these impacts have been documented in numerous publications, finding the right information for your type of utility or geographic region can be difficult and sometimes overwhelming.
This document describes how Danish municipalities can respond to flooding problems expected as impact of climate change. The report provides an overview of information available about climate change in Denmark, which impacts the urban drainage systems.
The most significant factors are the increase in extreme rainfall and rise in sea level. Examples of how floods can be prevented and avoided describe available methods for analysing existing urban drainage networks and evaluating the impact from various flood mitigation augmentations.
Water supply and sanitation is an important sector of investment supported by the Asian Development Bank (ADB). For the period 2006–2010, ADB-approved investments in water supply and sanitation amounted to approximately $4 billion, representing 7% of ADB’s lending portfolio over the same period. Total investment in water supply and sanitation for the period 2011–2014 reached in excess of $5 billion.
The provision of water supply and sanitation services is particularly vulnerable to projected changes in climate conditions (temperature and
precipitation among others), in the frequency and intensity of extreme weather events, as well as in the projected rise in sea level and the
intensification of storm surges.
This document provides guidelines for accounting for methane (CH4) and nitrous oxide (N2O) emissions from municipal wastewater treatment, discharge and sludge processing in New Zealand. Emissions from on-site septic tanks are also covered.
The present report focuses specifically on incorporating resilience into the engineering design of drinking water and sanitation infrastructure. It focuses narrowly on resilience in relation to three hazards, floods, droughts, and high winds. The focus is on these hazards because they are the
main threats that climate change is expected to pose to water infrastructure.
Celebrating World Water Day 2021 on March 22nd, six experts, backed by five organizations (Stockholm Environment Institute, GIZ, Viva con Agua, WaterWorX and EXP-Consult) present a plea for greater and wider collaboration to shape the water sector to become more climate resilient. Improved management of water and sanitation services is fundamental not only for climate change adaptation but also for mitigation – and collaboration plays a major role in this. The report published under the umbrella of SuSanA describes important guidelines as well as specific approaches and regulatory framework conditions for cross-sectoral collaboration, as well as case studies from around the world. Low-carbon and climate-resilient water and sanitation services are technically feasible and economically viable. Cross-sectoral collaboration is needed, but must be done proportionately, with due consideration of opportunities and risks. With an appropriate regulatory framework in place, this can add important value for the implementation of SDGs and the Paris Agreement.
This methodology outlines the path for establishing business-as-usual (BAU) emission scenarios water and wastewater utilities could exhibit in the mid-term if the current management and practices were to continue in four easy steps. The approach is created on the basis of the “Energy Performance and Carbon Emissions Assessment and Monitoring” (ECAM) tool. Based on the projected future values of key parameters, the variables that are necessary to be inputted into ECAM – the ECAM inputs – for the computation of GHG emissions can be quantified for a certain point of time. This step is facilitated by the “Tool of Projecting ECAM Inputs for GHG Emissions as BAU Scenarios (PEIGE)” in Excel format, which automatically calculates future values once users have entered the current ECAM input values and BAU trends. BAU scenarios can help to understand the impacts of adopting a low carbon policy and can serve as a technical component to inform/decide strategic planning on climate change, emissions mitigation goal setting and long-term climate policy design.
