The aim of the project is to increase the efficiency of the control of individual waste water management systems (INTS) and to reduce the administrative burden for participants in waste water management processes. The main challenge is: Update the accounting and control procedures for IPRS and implement the electronic means necessary for their implementation. This project will develop and implement a State-level Waste Water Management Information System (NTIS) to achieve the objective and achieve the objective. The following changes to the current situation are planned to be implemented during the project: I. Enabled to enter data on ITS recorded on the territory of Lithuania in a single information system; II. Enable remote monitoring of IPRS by municipalities through the system; III. Enable the recording of IPRS-related services (sewage, connection to centralised waste water systems, contracting with the public water supplier and wastewater manager, waste water transporters, etc.); IV. Allow for the introduction of the results of IPRS checks when travelling to the location of the installations at a natural or legal person; V. Enabled to provide the European Commission with the necessary data on the management of INTS in Lithuania for the implementation of Directive 91/271/EEC.
