The city of Bad Mergentheim in Baden-Württemberg signed a contract for a new sewage pressure main between Markelsheim, Igersheim and Bad Mergentheim on 12 October 2026. The contractor is Boller-Bau GmbH. The notice states 6,000 m of pressure main DA 315 and 730 m of DA 90, plus a pump station, shafts, water mains and ducts in the same works.
The notice was published on TED on 14 October 2026, two days after signature. This briefing sets out what it states, class by class, so a supplier can see which products appear and in what quantity.
The contract in figures
The value recorded for the contract is 6,166,789 EUR. At the exchange rate of 13 October 2026 (5.3363 RON per EUR) that is 32,907,836.67 RON. The works period is 13 months. The notice names no lots and no consortium.
The notice title is "Neubau Abwasserdruckleitung in Markelsheim-Igersheim-Bad Mergentheim". Its description groups the works under three headings: sewage facilities, supply lines, and restoration of traffic areas, including the cycle path between Markelsheim and Igersheim. The contract notice is on TED, notice 707779-2026.
The purpose of the main is described in the tender text as mirrored on a procurement portal: the municipal sewage utility intends to close the treatment plant in the Markelsheim district and to pump the wastewater to the Mergentheim network instead.
Sewage pipes: 6,000 m of DA 315 and 730 m of DA 90
The largest single line in the notice is the pressure main. The notice lists it in its own words:
6.000 m Abwasserdruckleitung DA 315
and, as a second line:
730 m Abwasserdruckleitung DA 90
DA is the outer diameter in millimetres, so these are pressure pipes of 315 mm and 90 mm outside diameter. The notice does not state the pipe material for these two lines. Two gravity sewer sections are listed as well: 27 m of stoneware sewer DN 400 and 50 m of reinforced-concrete sewer DN 600.
Related earlier briefing: the Kiel pressure main and road contract covers another German sewer and pressure main. Pipe and pump products for this kind of work are collected on the pipes and pumps page.
Pump station and shafts: precast and reinforced-concrete items
The notice lists the following structures with their counts:
- 1 sewage pump station, reinforced concrete, DN 2000
- 1 pressure main end shaft, PE, DN 1000
- 15 pig stations and ventilation shafts (Molchstationen u. Be-/Entlüftungsschächte)
- 2 inspection shafts, reinforced concrete, DN 1200 to DN 1500
- 1 water main shaft, 2.5 x 2.5 m
"Sb" in the notice stands for Stahlbeton, reinforced concrete. These items belong to the drainage and precast concrete class; see the drainage and precast page for how Trassa groups them.
Water mains and ducts in the same works
The supply lines are part of the same contract. The notice states:
1.090 m Trinkwasserleitung DN 200 GGG
alongside 120 m of DN 150 and 100 m of DN 250 in the same material designation. GGG is the older German abbreviation for ductile cast iron. Further down the list come 5,500 m of ducts (Leerrohre) of outer diameter 90 mm and 2,500 m of multi-duct bundle 12x12.
Road and cycle path restoration
The restoration quantities are stated by surface, not by length:
- 3,600 m² asphalt surfacing on path width and 1,250 m² asphalt reinstatement in the trench area
- 200 m² concrete paving and 110 m of kerbs and edgings
- Cycle path Markelsheim–Igersheim: 1,850 m² asphalt surfacing in full or partial rebuild and 3,450 m² asphalt renewal
- 400 m² block-set wall (Blocksatzmauer)
For the notice's own sentence on paving: "200 m² Betonpflaster".
How to read the dates
