Development of the Parsdorf industrial estate
blanket coverage – 2,000 meters of vitrified clay pipes

Diana Klose, Steinzeug-Keramo GmbH

In May last year the deal was sealed: the last plot of land in the new industrial estate in Parsdorf, a part of the township of Vaterstetten, just five minutes by car east of the “Neue Messe München” (New Munich Trade Fair Centre) and with direct access to the A 94 autobahn. The Parsdorf industrial estate had officially taken off just one month earlier with the ground-breaking ceremony for a DIY superstore. By the end of the year, the once green meadows had been turned into a busy construction site. In facilities with a total floor space of 210,000 m², enterprises, retailers, specialist stores, gastronomy, traders, and service providers one by one moved in to take up business; the development zones and green spaces extend over a further 90,000 m². More than 250 million euros were invested in buildings and infrastructure, and about 1,000 jobs have been created. 

First underground, then on top

The phase between the first cut of the greenfield location and the start of overground construction activities, however, was taken up with the measures necessary to develop the site, for example the installation of the supply and disposal infrastructure. These measures naturally also include a safe and reliably functioning wastewater drainage system; in Parsdorf, these activities are the responsibility of the gKu VE | München-Ost Ver- und Entsorgung company, based in the nearby town of Poing. This company put out the sewage system project for public tender in 2013; the planning was taken care of by the GFM Beratende Ingenieure GmbH consultancy company, Munich, and in September 2013 the SWIETELSKY Baugesellschaft mbH company, Ebersberg, broke the ground for the installations.

Secure basis in the entire industrial estate

Since there was more than enough space available on the greenfield site, the decision for the construction of the sewage system by the open trench method was an easy one to take. Over the entire industrial estate, all main pipe systems and all property drainage pipes up to the manhole have been constructed using vitrified clay pipes: about 2,000 meters of vitrified clay pipes of different diameters (see table) and the corresponding number of fittings were laid in the gravelly subsoil above the groundwater level, involving the excavation of about 7,000 m² of soil. Despite project-related interruptions, the construction activities were completed in March 2014.
