In this research, first, the factors that create claims in Water and Sewage projects and also the key factors of success in projects have been identified. Then, by distributing the questionnaire among the experts, the importance coefficient of key success factors was calculated by the fuzzy SWARA method. The weighting results showed that among the 10 key factors of success, scheduling factors, safety and health, and cost have the first to third important factors.
