ABSTRACT
In recent history, asbestos cement pressure pipes were widely used for delivery of potable water from water sources to human settlements. Nowadays, most of the asbestos cement water mains are approaching the end of the service life. Although asbestos cement water mains are not considered to represent a significant risk to public health when in normal use, asbestos fibres released into air during rehabilitation of water mains pose a cancer and lung disease hazard. The contribution deals with problems of rehabilitation of asbestos cement water mains in the Czech Republic as well as with safety and disposal issues. The first part of the contribution briefly describes production of asbestos cement pipes and provides information on installation of asbestos cement water mains as second part deals with health effects of asbestos on humans. The final part of the contribution focuses on principal laws and regulations concerned with asbestos waste management in the Czech Republic and safety in the workplace during rehabilitation of asbestos cement water mains.
