Recently, the first membrane treatment technology supported drinking water backup source project in the mountainous area in the Haishu District was completed and put into use. Thanks to this project, villagers in the Mao'ao Village and the Huimin Village in the Hengjie Town now enjoy "fresh water". In order to improve the drinking water conditions of villagers in the mountain villages, the Hengjie Town launched a new project for backup of drinking water in the Mao'ao Village and the Huimin Village last July. It is reported that the project is invested with a total of 3 million yuan and equipped with digital technologies such as online monitoring equipment and remote monitoring equipment for water quality and quantity monitoring.
