Abstract

Hotel is one of the biggest water consumers. The water needs category in hotels varies from drinking water requirements to garden irrigation needs where each requirement has different water quality criteria. But in Indonesia, all water needs in hotels are met with one water quality, which is clean water. This causes waste is limited clean water resources and the cost of procuring clean water at the hotel. The use of greywater as an alternative water source in hotels is a way to reduce the consumption of clean water in hotels. The use of greywater can be maximized by processing greywater according to each water quality criterion needed at the hotel. Therefore, this research was conducted to aim for developing a scheme for utilizing greywater to meet water requirements in a hotel based on the category of water quality needs and criteria. The potential of greywater in a hotel is reviewed through literature studies and case studies in a five-star hotel in Jakarta. The results showed that the use of greywater in hotels has the potential to save up to 65.20% of clean water consumption, equivalent to 43.04 m3/day, and save water supply costs of IDR 10,607,000 per year.
