WP1 Management:The SODISWATER Project is progressing on schedule and according to plan. All of the deliverables have been achieved as expected. Scheduled management meetings took place in Dublin (Oct 2006), Almeria (Feb. 2007) and Zurich (Aug 2007). The project pre-funding was received and disbursed between partners as specified in the consortium agreement.  Smiley-Face Diary developed by CSIR for care-givers with limited literacy to record diarrhoeal disease rates during the field Study WP2: The Health Impact Assessment (HIA) All studies have received ethical approval from their requisite authorities and appropriate study areas have been identified within Kenya, S, Africa and Zimbabwe. Study supervisors and data collectors have been recruited and all attended a training workshop in S. Africa in June 2007 where they received instruction in anthropometric measurement and using the data collection software developed for the Hand-held computers. Methodologies for the recruitment of study subjects and recording of study data have been completed. All preparations are now complete for the beginning of the Household selection and pre-survey phases of the work-programme. Inactivation kinetics of bacterial populations exposed to real sunlight conditions expressed in units of log reduction.. Error bars indicate standard error of triplicate measurements. WP3 Pathogens: An examination of the bactericidal capacity of SODIS against Yersinia enterocolitica, Camplylobacter jejuni, Enteropathogenic E. coli, Staphylococcus epidermidis and endospores of Bacillus subtilis in Task 3.1 has confirmed that all pathogenic bacteria examined so far are completely inactivated within 6 hours of natural sunlight. This work has been submitted for publication in Applied & Environmental Microbiology. Work on tasks evaluating the efficacy of SODIS against viral and parasitic pathogens and validation of simulation models continues on schedule. WP4 Enhancement Technologies:Analysis of prototype flow-through SODIS reactors indicates that these are unlikely to be effective without the assistance of photocatalyst and reflector enhancement technologies. The additional compound parabolic collectors and photocatalyst enhancements are under construction in P.S.A. and UUJ and will be added to the flow-through reactor prototype in the next reporting period. Development of the batch photocatalytic reactor and UV feedback-control sensor is proceeding on schedule in UUJ however the batch UV indicator tape research in RCSI has been delayed due to the late availability of the post doctoral researcher for this task. This person is now in post and work is proceeding. WP5 Dissemination:Analysis of case studies, adoption studies and community status quo surveys have all been completed by EAWAG researchers working in collaboration with their Zimbabwean partners IWSD despite the economic difficulties being experienced there at present: Analysis of the data is now underway. Agreement has been given informally for a SODIS session to be included in the Sept 2009 conference on Advanced Oxidative Processes in Chania, Crete. Preliminary approached have been made to the WHO HWTS Network to host the 2009 meeting in Dublin. These have been positively received but are still under consideration. Four papers resulting from SODISWATER research have been published in peer-reviewed scientific journals. All four papers acknowledge the support of the EU in this research.
