AS Tallinna Vesi's operational performance in the nine months of 2016

Teade

Our first priority is to provide our customers with high-quality drinking
water, reliable water supply and wastewater discharge services. Similar to
previous years, the nine months of 2016 can be characterised with excellent
quality levels of our services. We will continue to focus on maintaining and
improving all our key performance indicators so our consumers can rely on the
service they receive. The nine months of the year confirm that the quality of
drinking water in Tallinn has been excellent already for years, thus, we keep
encouraging people to prefer tap water for drinking water. Low leakage level
and significantly decreased number of sewerage blockages are yet another
positive signs of the Company’s excellent performance.

Tap water is drinking water

Tap water quality remains excellent and is comparable to that of any other
country in West-Europe. Strict legal requirements apply to the quality of
drinking water and the compliance with these is monitored in accordance with
the drinking water monitoring programmes approved by the Health Board. Water
quality complies with the legislative acts. 

During the nine months of 2016, we took a total of 2207 samples across our
service area (Tallinn and Saue), from the consumers’ taps and carried out
17,630 water analyses. 99.91% of the water samples were compliant with all the
requirements. Thus, only two samples exceeded the limit values. We immediately
carried out maintenance works on the water network on the relevant street
resulting in the new samples being fully compliant. Steady high quality level
is a result of an efficient water treatment process, preventive actions
reducing the number of water bursts on the network, and timely maintenance of
the water network. 

The results of drinking water analyses taken from the water from Lake Ülemiste,
Water Treatment Plant, ground water and customers’ taps can be found on the
company’s web page. 

A reliable service

It is important for all consumers to have a reliable and high-quality service
available 24/7. We therefore strive to plan and optimise our activities to
minimise disruption and inconvenience, wherever possible. 

Over the years customers’ need to inform us of problems has shown a declining
trend. The number of customer contacts on various topics has increased to some
extent in the first nine months of 2016. At the same time, the number of
written complaints and failed promises has declined during the same period.
There were 29 complaints submitted in the nine months of 2016, compared to 57
complaints in the same period in 2015. We continue to work hard so that people
would have less reasons to be unsatisfied. 

Cleaner environment

We provide wastewater discharge service to nearly one third of the Estonia’s
population located in Tallinn and some of the surrounding municipalities. The
company’s wastewater treatment plant is located at Paljassaare, which is
constantly being updated with new technologies, to ensure continued compliance
with ever tightening environmental legislation. During the nine months of 2016,
effluent was again 100% compliant with the stipulated permit requirements. 

We remain focussed on reducing the possible risk of flooding within our network
and preventing any pollution incidents. The number of sewer blockages provides
a good indication as to how we are proactively managing the network, for
example jet washing. During the nine months of 2016, the number of sewage
blockages reduced by 13.72% compared to same period in 2015, i.e. when during
the nine months of 2015 we eliminated 583 blockages, then this year we
eliminated 503 blockages in the same time period.
