About Wayleave:

A Wayleave refers to a corridor that is clear of buildings or any other unauthorized structures, which is legally acquired for public use. Songas acquired a total of 229 Km Marine and Mainland Wayleave from Songo Songo Island to Ubungo Power Plant in Dar es Salaam for the installation of the 16 inches Main Gas Pipeline and 16 Km Wayleave from Ubungo to Wazo for the installation of a spur line to Twiga Cement Factory and Independent Power Tanzania Ltd. The Marine Wayleave has a width of one Km and the mainland Wayleave has a width of 30 to 60 meters.

Songas Gas Pipeline and the Wayleave are marked by above ground signs to indicate the general location and contact information.

To ensure public safety, Songas is closely monitoring its systems through a combination of safety programs; including but not limited to monthly low-level flying, visual ground inspection, and computerized system report.

Songas has established a process which identifies, mitigates and/or controls all potential risks to the High Vapour Pressure Gas (HVPG) pipeline system from the works to external third party sources.

Wayleave foreign crossing

Refers to any kind of activity which is done close to, across, underneath or above the natural gas pipeline way leave from Songo Songo Island to the Ubungo Power Plant and the Spur Line to Wazo Hills and IPTL. This includes, but is not limited to highways, municipal, district or private roads, railways, irrigation ditches, drains, drainage ditches, sub-surface drains; overhead lines or underground cable and other pipelines.

ALL FOREIGN CROSSING ON SONGAS’ WAY LEAVE WILL BE INSPECTED AND APPROVED BY SONGAS PRIOR TO THE START OF ANY WORK.

All the work shall be done in accordance with the Songas Terms and Conditions and within the approved Agreement. Should the Applicant fail to perform in accordance to the Terms and Conditions stated below, then, Songas may at any time decide to cancel the permit.

Health, Safety & Enviroment

The main threat to the safety of the pipelines arises from people or companies doing unauthorized activities within the vicinity of High Vapour Pressure Gas (HVPG) Pipeline without realizing the exact location of the pipeline. The excavating equipment can accidentally strike and damage the pipeline. Severe damage can cause the pipeline to leak or rupture, resulting in an immediate hazard to life and property. Even damage, which appears to be minor, can, over time, weaken a pipeline, causing a leak or rupture in the future.

Any works within the pipeline way leave has potential to create health, safety and environmental hazards. All people working within the way leave shall wear proper PPE and work to minimize risks and environmental impacts.
If the work will be done in heavy forest areas inhabited by wild animals, then a game warden with a gun will have to be hired till the completion of the work.
