Objectives:-To assess and compare directly quantified GHG emissions against estimates -To identify some of the drivers linked to GHG emissions from septic tanks-To contribute to the current Intergovernmental Panel on Climate Change guidelines in methane emissions from domestic wastewater by providing septic tank specific guidelines.-To propose measures for reducing methane emissions from septic tanks.Summary:The project seeks to understand the actual quantities of GHG emissions from septic tanks to add value to the current estimates. Low-middle income countries have seen a trend of growing numbers of onsite wastewater treatment (Koné and Strauss, 2004), therefore it is important to conduct research in these countries and make countries aware of their GHG contributions to global inventories. Information about the actual GHG emissions can be used to guide future growth of septic tanks and design mitigation pathways.The research is to be conducted over 12 to 18 months in a low-middle income country (urban area) with several septic tanks in the same geographical location. A portable gas analyser capable of detecting CO2, N2O and CH4 emissions will be used. The research will help to add value to current GHG emissions estimates with a view to designing mitigation strategies regarding methane emissions from septic tanksThe research fits under several EPSRC's themes such as Global uncertainties due to the current lack of accurate GHG emissions inventories in some sectors such as sanitation, and Engineering due to the project trying to fight global warming by source mitigation in the sanitation sector.

目标：-评估和比较直接量化的温室气体排放量与估计值-确定与化粪池温室气体排放有关的一些驱动因素-通过提供化粪池特定的指南，为当前政府间气候变化专门委员会关于生活污水甲烷排放的指南做出贡献。-提出减少化粪池甲烷排放的措施。总结：该项目寻求了解化粪池温室气体排放量的实际数量，以增加当前估计的价值。中低收入国家出现了现场废水处理数量不断增加的趋势(Koné和Strauss，2004年)，因此，重要的是在这些国家开展研究，使各国意识到其温室气体对全球清单的贡献。关于实际温室气体排放的信息可用于指导化粪池未来的增长和设计缓解路径。这项研究将在一个中低收入国家(城市地区)进行，时间为12至18个月，在同一地理位置有几个化粪池。将使用能够检测二氧化碳、N2O和CH4排放的便携式气体分析仪。这项研究将有助于为目前的温室气体排放估计增加价值，以期设计有关化粪池甲烷排放的缓解战略。这项研究符合EPSRC的几个主题，例如由于卫生等一些部门目前缺乏准确的温室气体排放清单而导致的全球不确定性，以及由于该项目试图通过卫生部门的源头缓解来对抗全球变暖的项目。
