Sewage

Basic (Geodetic) module

Creates and maintains basic spatial records and an attribute description of sewers, buildings and equipment of the sewage system. It is an upgrade of a Desktop Viewer and as such, has also all of the same functionalities as that module.

The sewage system is described with over 40 point, line or polygon spatial layers. The description takes into account not only narrow sewers, manholes and other sewage facilities, but it also allows the recording of collection septic tanks, small wastewater treatment plants, open streams, right up to the layer in which users can log data errors.

When inputting data, it is possible to predefine the values of certain attributes in each layer, and for each attribute for which this is possible, lists can be opened, i.e., catalogues.

For attributes whose values are used in the quality control process, “locked” lists are initially created, i.e., lists that the user cannot alter.

The graphical editor is highly efficient. It has a series of specialized, embedded commands. One of them is for complex movements such as the movement of a certain node. For example, when a manhole is moved, its associated sewers will also move.

The module manages a quality height description of the system. All commands from the graphical editor (e.g. connection of sewers, splitting of sewer elements into segments) automatically adapt the height description as well.

The longitudinal profile is an integral part of the module and any possible deficiencies in the height description are easily spotted on it.

The system gives a quality description of both gravity and pressure sewers, and soon will also be able to handle vacuum systems.

The greatest value and functionality, which competitors’ solutions do not offer, consists of controls of completeness of attribute description and quality controls of logical data input. There is no type of sewer, equipment or building where the functional correctness of the spatial position in relation to other parts of the system, is not controlled. The controls point out to user all incorrect data entered, directing him toward all locations where faults must be resolved. The data input process cannot be completed, in other words, data cannot be stored on the server, before all detected faults/deficiencies have been corrected. There are more than 50 controls built into the system that function like a series of increasingly finer sieves that gradually filter out all deficiencies.

The necessity of this approach arises from the fact that insufficient or unverified data should not serve as the working basis of all of the planned modules which will later use that data in quite complex procedures. Perhaps the most illustrative example is the need for the software to render the longitudinal profile of the gravity and pressure sewers, and associated facilities (pump stations, retention basins). Any error in data completely prevents this procedure, or even worse, will cause the wrong solution to be recommended.

The module enables simultaneous changing of data by multiple users, but without the possibility that these changes overlap. The procedure is based on defining a polygon of interest, i.e. specifying an area in which the user wants to modify the data. The specified area is reserved for only one person. There is a direct attribute editing, i.e., attribute editing without having to define the area of interest is available as well. This of course applies only to that part of attribute description that is not essential for the control process.

In a separate part of the module, the user can, in advance, show and describe by attributes, all types of piping and equipment, so that the attribute description can later be reduced to only the choice of the appropriate type of piping and equipment.

This is a basic and initial module which is required for the establishment of the technical information system of the sewage system. The rest of the modules rely on data created by the basic module while working, and without it, they cannot function.
