AS Tallinna Vesi’s operational performance in the 1st quarter of 2019
AS Tallinna Vesi achieved excellent operational results in the 1st quarter of 2019. We were glad to see consistently high performance in the parameters reflecting the quality of both drinking water and treated effluent, as well as customer service.
Reliable water service
The quality of drinking water was excellent in the 1st quarter of 2019. Water samples taken from customers’ taps, were 99.73% compliant with the requirements. A total of 774 water samples were taken during the 1st quarter. The professionalism of specialists managing the treatment process at Ülemiste Water Treatment Plant, as well as renewal and maintenance of water network, are instrumental in ensuring high quality water to our customers. The average water disruption time to individual properties was 2 hours and 35 minutes in the 1st quarter of 2019, whereas, the result in the same period of 2018 was 2 hours and 52 minutes.
We continue to make targeted capital investments to ensure the continued reliability of the infrastructure. In the 1st quarter of 2019, we performed reconstruction works on water pipes and sewers on Reidi street, Gonsiori street and Hiiu-Suurtüki crossroads in collaboration with the City of Tallinn.
The level of leakages in the water network continues to be at a record low. This year we achieved 12.86% for the level of leakages in the first quarter, which is quite an improvement in comparison with 15.19%, in the 1st quarter last year.
High service standards
Besides outstanding operational performance, the Company has set itself high standards to provide first-class customer service. We have set clear and challenging targets and give promises to our customers in terms of the speed of our response and problem-solving. No promises have been broken in 2019. We also think it is fundamental to provide our customers with important information, or respond to their questions as quickly as possible. Therefore, we measure the speed of our responses, and have set a target to respond within two working days, to non-complex written requests.
In order to further improve customer satisfaction, we continue to develop our customer interaction channels, and look for ways to make the processes quicker and more convenient. This year we are introducing a new self-service environment, and we are also in the process of upgrading the mobile phone application, to enhance its functionality and provide better information.
We care for the environment
In the 1st quarter of 2019, the treated effluent leaving Paljassaare Wastewater Treatment Plant was compliant with all stipulated quality requirements. For the purpose of assessing the treatment efficiency and the quality of wastewater, we monitor pollutants in both the incoming wastewater and treated effluent discharged into the sea. Wastewater laboratory analyses the samples taken from different stages of the wastewater treatment process, and the information received thereby allows us to further improve the treatment efficiency and effluent quality.
