Lviv is a city of national and regional significance in Ukraine and has been a UNESCO World Heritage Site since 1998. In terms of population, it is the seventh largest city in the country with approximately 718,383 people living in Lviv as of 1 March 2021. Lviv City Communal Enterprise “Lvivvodokanal” is a municipally owned utility company providing water supply and sewerage services to residents and enterprises within Lviv Territorial Community. The Company operates 1100 km of water networks, water treatment facilities and 17 water intakes located at distances of 10 to 105 km from the City. The city’s water supply comes from 7 directions around Lviv, ranging from 20 to 100 km in length, namely from 190 underground wells. This means all the water inflowing to Lviv is of good quality underground sources. However, treatment is needed for the iron, manganese, gases (hydrogen sulphide and carbon dioxide), and hardness. Additionally, the enterprise’s water supply facilities were built in the 50s and 60s of the 20th century and are currently in poor technical state, are worn-out and obsolete. The current tariff for water and wastewater services does not cover the basic costs of the enterprise, and the investment component in the tariff is so low that it does not allow for any significant upgrade and reconstruction projects. Consequently, the provision of water supply and wastewater disposal services in the city of Lviv are reasonably jeopardized. At present, during the period of military aggression of the Russian Federation against Ukraine, “Lvivvodokanal” provides water supply and sewerage services in full not only for the city residents, but also for about 200 thousand internally displaced people who have taken refuge in Lviv from the hostilities. 

AQUAMON will enhance the enterprise’s urban water management plans, improve water quality and ensure compliance with the existing EU water policy legislations, delivering a ‘whole system monitoring approach’ for urban water quality. This will involve the following technologies across three dif erent scenarios: Scenario A: “Safeguard Drinking Water Quality”: This includes innovative multiparametric sensors that will be installed in the water distribution network to ensure safety in the event of pollution. An IoT-connected drinking water analyzer will autonomously and efficiently monitor secondary disinfectants, organic chemicals, and residual chlorine throughout the network, with easy deployment at any tap, minimal reagent use. LOC sensors will be employed for real-time, in-situ monitoring, utilizing the colorimetric ferrozine method for high-quality dissolved iron measurements, capable of detecting both Iron II and Iron III through onboard acidification and reduction processes. Additionally, these sensors will provide real-time pH measurements using spectrophotometric techniques. All collected data will be integrated into a cloud-based dashboard, offering a comprehensive view of multi-parameter water quality data fostering public involvement . Scenario B: “Pollution Prevention in Sewerage Infrastructure”: This includes IoT-enabled chemical analyzers and ML-based models located at strategic locations within the watershed to provide real-time monitoring of CSOs discharges and flooding events XR-enabled inspection system will enable collaborative management from remote to boost real-time decision-making in field operations. The collected data will support pollutant propagation modelling within the water supply system, and flood risk mapping under various climate scenarios and external incidents. Scenario C: “Rehabilitation of Wastewater Treatment Facilities”: This includes a QMRA diagnostic tool designed to simulate and perform quantitative microbial risk assessments, as well as to analyse and predict potential water quality impacts arising from compromised water distribution and sanitation systems,. The tool aims to analyse existing risk related to CSO discharges and flooding events and to assess the effectiveness of safety measures in order to expedite the recovery of Ukraine’s worn-out and obsolete water facilities due to war. All the collected data will be integrated into a 4D Digital twin, supporting recommendations to strengthen the implementation of EU and/or national legislation
