AS Tallinna Vesi’s operational performance in the 1st quarter of 2019

Teade

AS  Tallinna Vesi achieved excellent operational results in the 1(st) 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 1(st) 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  1(st) 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
1(st) 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 1(st) 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 1(st) 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   1(st) 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.
