The main task of the external networks department of Merko Ehitus is building external networks of water, sewerage and gas pipelines, installing sewerage pump rooms and constructing and renovating storm water systems.

Our aim is to carry out works with high quality and according to the good building practice, solve the water supply and sewerage problems of our clients in the best possible way, while damaging furbishing, roads and buildings as little as possible. We have the best engineering team and we use modern tools and methods.

Out of the completed objects we would like to set forth instalment of pipelines by the closed or directional drilling. A good example is construction of the Pärnu siphons on the Raba, Vingi and Lai street. Furthermore, the important objects are the construction of the external networks of the Rae techno-park, technically complicated extensions of the water and sewerage network in Tartu Ropka district and Valga town.
