Success Story: BASF IT Services

Re-Engineering Water Information System – Waste Water Cadastre

Company portrait

BASF is the world’s leading chemical company. Its portfolio includes chemicals, plastics, performance products, agricultural products and fine chemicals as well as crude oil and natural gas. The Ludwigshafen plant, located on the Rhine, is the world’s largest integrated chemical complex. At the same time, the more than seven square kilometre site is the headquarters of the BASF Group and the centre of research.

Waste water register (ABKA)

The new version of Appendix 22 to the Framework Wastewater Management Regulation, which came into force on 1 January 1992, requires the preparation of a detailed wastewater register for all wastewater discharging facilities. This was first drawn up for BASF Aktiengesellschaft in Ludwigshafen in 1993, even then with the assistance of PTA GmbH. Since then, the data of all wastewater-relevant plants have been recorded in the ABKA (wastewater register) system, which is part of the Water Information System (WISS). In order to create the ABKA, the wastewater-relevant information (bbA quantity, freight, ingredients, etc.) of the respective plant and, if applicable, of the manufactured products including partial flows must be entered, processed and output.
The waste water cadastre of BASF Aktiengesellschaft distinguishes between two types of cadastral plants:

  • B-ABKA (company wastewater register) for less wastewater-relevant plants
  • T-ABKA (partial flow-related wastewater register) for wastewater-relevant companies

In autumn 2003 PTA GmbH, together with BASF IT Services, completed the reengineering of the sewage register project. The main goal of the re-engineering project was to enable continuous data collection in the wastewater cadastre, so that the data of the plants can be kept up-to-date at all times.

The cooperation

The many years of experience of PTA and BASF IT Services as well as the good cooperation among each other and with the employees of BASF Aktiengesellschaft have led to this success. All those involved were very satisfied with the result.

Aims of the re-engineering project

  • Ongoing updating of data
  • Comfortable contemporary Windows interface
  • Flexibility regarding future functional requirements due to modular design
  • Integration of the recorded mitigation measures and water law notifications into the wastewater register
  • Treatment of product closures, relocations and results of operational measurements
  • Traceability when a product is relocated
  • Conversion of the version cadastre to a continuous cadastre with freely selectable evaluation periods (annual cadastre) and combination of several annual cadastres into one official cadastre
  • Simple operation for queries and searches
  • History management

The tasks of the PTA

The requirement for PTA GmbH was to implement the wastewater register under the coordination of BASF IT Services, based on a given specification. Design, implementation and introduction of the application system were carried out by both companies together in close cooperation. Furthermore, PTA prepared the system documentation for the subsequent operation of the system by BASF IT Services.
The following tasks, among others, were to be performed by PTA:

DV-technical design for numerous complex conceptual specifications, for example for

  • the version register management
  • the history management
  • the treatment of product shutdowns / relocations and results of operational measurements
  • the integration of mitigation measures and water law notifications
  • the preparation of system documentation

Testimonials

“The reengineering of the wastewater cadastre, which was implemented by PTA together with BASF IT Services, now allows for the timely and efficient collection, evaluation and balancing of the relevant information for the authority.
The many years of experience of PTA and BASF IT Services as well as the good cooperation with each other and with the employees of BASF Aktiengesellschaft have led to this success. All parties involved were very satisfied with the result”.
