Managing Urban Sewage
An Introductory Guide for Decision-makers

VI. Information Systems

Information systems and other knowledge management tools can help improve the efficiency and reliability of urban sewage infrastructure. Some examples are described below.

A. Rainfall Information Systems

Some cities have established rainfall information systems to protect residents from floods. These systems are based upon the electric waves emitted from radar and reflected by raindrops and identify areas of rainfall and intensity. This information is then sent to pumping stations, sewage system maintenance offices and treatment plants to allow adequate time for staff to prepare and to ensure immediate pump operation. Data can also be collected and processed at a central information processing facility.

B. Sewage Mapping and Data Management Systems

It is also important to obtain accurate information on sewage facilities in order to maintain and manage them effectively. In Tokyo, a sewage mapping and information system, SEMIS, was installed in April 1986. SEMIS has allowed Tokyo to systematize its sewage facility information and create a database for operational purposes.
