GENERAL CONTRACTING FOR NETWORKS AND FACILITIES | WATER AND SEWAGE NETWORK CONSTRUCTION

Efficient water and wastewater infrastructure is the foundation of any development—from single-family homes to residential housing estates and massive industrial complexes. For over 20 years, TERLAN has been designing and building utility networks and service connections that guarantee trouble-free media transmission. Operating nationwide, we combine traditional craftsmanship with cutting-edge trenchless technologies.

We offer full investor support within the Design-Build delivery system. As part of our water and sewage network and connection services, we provide:

Comprehensive Design: We deliver complete construction and detailed engineering designs for water supply and sewage networks and connections.
Value Engineering: We analyze soil conditions and spatial development plans to select the most efficient and cost-effective installation methods.
Custom Cost Estimation: Every budget is prepared tailored to specific needs, material specifications, and financial requirements.
Legal and Formal Administration: We continuously coordinate administrative processes, perform technical handovers, and secure agreements with network operators (Water and Sewage Utilities / PWiK) and municipal offices.

We know that network construction does not have to involve deep excavations or the destruction of landscaped properties, roads, or urban greenery. Alongside traditional open-cut methods, we specialize in trenchless technologies:

Horizontal Directional Drilling (HDD): A non-invasive method for laying underground utilities over distances up to 200 meters. It involves drilling a precise pilot borehole, reaming it to the required diameter, and pulling through the designed product or casing pipe. This is an ideal solution for crossings beneath roads, railway tracks, or watercourses.
Optically Guided Microtunnelling / Auger Boring: We operate an advanced machinery park dedicated to the trenchless construction of gravity sewers. Optical steering allows us to lay pipelines with millimeter precision, maintaining the rigorous gradients required for gravity drainage.

By choosing TERLAN as your water and sewage network contractor, you partner with a fully independent entity equipped with complete competencies and resources:

Over 20 Years of Experience: Our team comprises engineers and installers who have successfully delivered hundreds of kilometers of networks under diverse geological conditions.
In-House, Modern Machinery Fleet: We do not rely on subcontractors. We own our excavators, advanced drilling systems, and installation equipment, guaranteeing on-time delivery.
Technical Supervision: We provide continuous support from our engineers and seasoned site managers at every stage—from the first design sketch to flow commissioning.

Whether you require a local utility connection for a newly constructed facility or a transmission main for an entire municipality, TERLAN delivers stability, precision, and the highest quality backed by years of practice.
