The Effect of Second-Home Tourism on Sewage Treatment Practices

Sanitation and waste management are major issues across developing and developed countries, influenced by factors such as local infrastructure, public policy, and tourism. This research aims to analyze the effect of second-home tourism on sewage treatment quality in an area, particularly in relation to seasonal population influxes and the resulting strain on local infrastructure. In this literature review, we first analyzed the levels of second-home tourism in 6 cities in the United States, 6 cities in Spain, and the municipality of Çeşme in Türkiye. We then evaluated sewage treatment quality in those areas to assess tourism's impact on sanitation practices. The results indicated significant seasonal pressure on local wastewater infrastructure, resulting in a negative correlation between second-home tourism and sewage treatment quality in the area. We used Pearson correlation for our data analysis of the United States and Spain. By calculating a correlation coefficient of -0.89 (U.S) and -0.94 (Spain), we highlighted a strong correlation.
