Vitrified clay pipe systems in sewage technology
Sewage systems have to be operated for a long time with low maintenance costs, as repair and rehabilitation works are not only expensive but always damaging to the environment as well as on local residents, shops and traffic. On the other hand, reinvestment costs must be kept as low as possible. The use of vitrified clay pipe systems provides an ideal solution, allowing the decision-maker to invest in a convincing, sustainable and future-compliant sewage system: an economic product which is more durable than other materials. Vitrified clay pipes are the perfect choice and present the best arguments: sustainable and future-compliant investments are well received; the public appreciates cost-effective sewage disposal.
Very often only the initial investment costs are used as decision criterion for or against a certain pipe material – a fundamental error. Without including factors like life span, material properties, maintenance costs and energy consumption during the operating period as well as reinvestment costs and ecological factors, it is not possible to assess the economic efficiency. If all these aspects are taken into account in the calculation, it quickly becomes clear that vitrified clay pipes are the most economical solution because of their low actual costs per operating year.
The special properties of vitrified clay pipes are also appreciated in the sewage technology of industry and trade. Together with their resistance, the protection of soil and groundwater in the discharge of these effluents is at the forefront of future-oriented decisions.
Vitrified clay pipe systems in rainwater technology
Rainwater is now the focus of particular attention, as possible constituents play a major role in the discharge of rainwater into water bodies or the storage and further use of natural reserves.
Vitrified clay pipes are used in non-pressurized applications for collection, storage, drainage and infiltration. The mechanical properties of the pipes and fittings are of particular importance in these applications: dimensional stability and neutral behaviour in the water-soil space are of particular importance. This also applies to the use of drainage pipes, e.g. in the construction of special sports facilities.
