In an old residential area in Adama, Ethiopia, the existing water supply network consists of old iron pipes that are severely corroded and have a high leakage rate, affecting residents' normal water use. This renovation project is a small-scale public works project, covering only three streets and alleys in the residential area, with a pipeline length of approximately 12km. It mainly involves replacing the branch pipes entering households and the pipes in courtyards. Located in a high-altitude area with large temperature differences between day and night, and with soil that is slightly alkaline in some areas, the project is small in scale and will not have a wide impact.

The Belém, Brazil raw water pipeline project is a vital water supply and public service project for both the city and district levels, primarily serving the production and domestic water needs of more than ten towns and villages surrounding Belém, Brazil. The project traverses plains and low hills, passing through urban roads and riverbanks, facing numerous challenges including harsh winters, significant diurnal temperature variations, slight soil salinization in some sections, and balancing ecological protection with traffic flow during construction.

The Potosí Department, Bolivia water intake pumping station was built a long time ago, and the area has a complex water system with large fluctuations in water levels during the flood season. The water has a high sediment content, and some areas have relatively mild soil salinization. The upgrade and renovation project faces many challenges, such as replacing old facilities, complex operating conditions, and limited construction space.

A small food processing plant in Quicimetto, Venezuela, which mainly produces baked and canned products, needs to construct a new small steam pipeline to provide heating steam for its production equipment. Located in the suburbs on the edge of the coast, the plant is affected by slight salt spray. The steam pressure is 3–5 MPa and the temperature is 180–220°C. The pipeline is short and compact, and is considered an internal ancillary project for the company.
