Development projects involving digging works have caused major damage to the underground pipelines and other utilities in Malaysia. The Survey and Mapping Department has decided to collect data from all the local government authorities and the private sector companies involved in development projects that require digging. It will include data from companies like Tenaga Nasional Berhad (the largest electric utility company in Malaysia), Telekom Malaysia and Syabas (the Selangor water works company). The data will help in developing a comprehensive underground utility map of the country. Recently, the department organised a seminar to discuss the technology to be brought into the country for the purpose of carrying out underground utility mapping. Natural Resources and Environment Minister Datuk Seri G. Palanivel said that the underground utilities in the Klang Valley and Putrajaya have been mapped in the first phase. Now, the department plans to map underground utilities in the remaining parts of the country.
