EWURA carries out technical regulation with regard to regulated infrastructure and Services, as well as Health, Safety and environment (HSE).
Before EWURA came into being, the infrastructure and service standards including the quality of services, specification of pipeline gas, engineering specifications for construction and installations were negotiated between the Government of Tanzania and licences’.
In most cases, the utilized engineering specifications are based on a series of American Petroleum Institute (API) Standards, International Standards Organization (ISO), American Society for Testing and Materials (ASTM) International Standards, and American Society of Mechanical Engineers (ASME) Standards, including the Canadian Standards Association (CSA) Standards, such as CSA Z662-07.
Occupational Health and Safety (OHS) matters are regulated by the Occupational Health and Safety Act, 2003 under Occupational Safety and Health Agency (OSHA). Normally health and safety are monitored by EWURA by applying the best industry practices. Technical regulation focuses on maximum safety.
The main legislation governing OHS practices in Tanzania during construction and operations are:
- The Occupational Health and Safety Act, 2003,
- The Contractors Registration Act, 1997,
- The Accidents and Occupational Diseases (Notification) Act, 1953 and
- The Fire and Rescue Services Acts, 1985.
EWURA protect and preserve the environment by ensuring that all applicants perform the necessary studies to make an informed decision on the project. The Authority also participates in evaluation of Environmental Impact Assessments (EIA).
MTWARA TO DAR ES SALAAM NATURAL GAS PIPELINE PROJECT
The implementation of Mtwara to Dar es Salaam Natural Gas Pipeline Project is in progress under TPDC. The project includes the Madimba processing plant with three trains each 70 mmscfd capacity and SongoSongo Gas processing Plant with two trains each of similar capacity of 70 mmscfd. The Natural Gas pipeline from Mtwara to Dar es Salaam via Somanga Fungu has a diameter of 36 inches and the pipeline from SongoSongo to Somanga Fungu has a diameter of 24 inches. The total distance covered by the entire pipeline is 517 kilometers and the maximum capacity of the pipeline is 784 mmscfd. However, the capacity can reach as higher as 1002 mmscfd if the gas is compressed.
EWURA monitors and inspects the construction of natural gas infrastructures which includes processing plants at both SongoSongo Island (Lindi) and Madimba (Mtwara), the 24 inches marine pipeline from Songo Songo to Somanaga Fungu, the 36 inches pipeline from Madimba (Mtwara) to Kinyerezi (Dar es Salaam) and 16 inches pipeline from Kinyerezi (Dar es Salaam) to Tegeta (Dar es Salaam).
