Jena/Großlöbichau, 20.03.2026. – Due to the construction of a new drinking water pipeline and subsequent road renovation, the district road K154 will be fully closed for several months starting in April. The project secures the future water supply for approximately 1,000 residents in the eastern outskirts of Jena.
- What: Full closure due to pipeline construction (1,400 meters) and fundamental road renovation
- Where: District road K154 between Großlöbichau and Jenalöbnitz
- When: From Tuesday, April 7, 2026, until presumably the end of the year
- Diversion: A diversion route will be signposted on-site
- Stakeholders: Zweckverband JenaWasser and Saale-Holzland-Kreis
New High-Level Reservoir Goes Online
The Zweckverband JenaWasser began an extensive infrastructure project this week. A new drinking water pipeline is being laid over a length of approximately 1,400 meters. This is mandatory to connect the municipality of Jenalöbnitz to the new high-level reservoir in Großlöbichau, which has been under construction since late 2024 and is nearing completion.
The new water storage facility has a capacity of 300 cubic meters and is intended to supply residents in Großlöbichau, Jenalöbnitz, parts of Wogau, and the local industrial estate with fresh drinking water in the future. The water itself is treated at the waterworks in Burgau and pumped from there into the new reservoir. The commissioning of the facility is scheduled for late April 2026. It replaces the previous, outdated storage facilities of the two surrounding municipalities and brings the network up to current technical standards.
Synergy Effects on the K154
In order to implement the construction work quickly and safely, a full closure of the district road K154 between the locations of Großlöbichau and Jenalöbnitz will be necessary starting April 7, 2026. The Saale-Holzland-Kreis is utilizing the excavation already required for the pipeline construction for a sensible synergy effect: immediately following the laying of the water pipes, a fundamental renewal of the roadway will take place in this section. Due to this dual project, the full closure of the connecting road is expected to last until the end of 2026.
Background: Transport and Supply Network in Eastern Jena
The waterworks in the Jena district of Burgau is one of the central pillars of the regional drinking water supply. From there, the treated water is pumped into the surrounding high-level reservoirs to generate the necessary water pressure for higher-altitude municipalities such as Großlöbichau. The K154 serves many commuters from the surrounding villages as a direct feeder route towards the Bundesstraße 7 (B7) and further into the Jena city center. Road users from this region should plan for significantly more travel time for the duration of the construction work and use the signposted alternative routes. The close synchronization of civil engineering work by utility companies and municipal road construction is considered standard procedure to reduce construction costs and avoid burdening road users with multiple closures in consecutive years.
