%X In the last few decades, anti-negative pressure facility (ANPF) has been emerged as a revolutionary approach for sloving the pollution in the Second Water Supply System (SWSS) in China. This study analyzed implications of the safety in SWSS with ANPF, utilizing the water distribution network hydraulic model. A method of hydraulic simulation and security assessment was presented which was able to reflect the number and location of nodes that can be installed in ANPF. Benchmark results through two instance networks showed that 67% and 89% of nodes in each network did not fit the ANPFs for installation. The simple and pratical algorithm was recommended in the water distribution network design and planing in order to increase the security of SWSS.
