provided by the microbes of the sediment. It will increase both the area and time that
nitrified waste water will be in contact with the reducing microbes and thus is supposed to
increase the reduction of nitrate to nitrogen gas (denitrification) and release of nitrogen
from water into the atmosphere. The effects of various abatement measures of nutrient
loading will be modelled and the estimates of the most cost-efficient nitrogen removal
measures with improved spatial resolution will be provided. Schematic illustration of the
project structure is shown in Figure 2.

5.1. Actions (please follow the structure of your proposal).
5.1.1. Action A
A1: We selected Hämeenlinna/Paroinen, Keuruu and Petäjävesi for the sediment
filtration demonstration sites due to their proximity to LBS and UJ and based on
the interviews with representatives of water utility staff and authorities (M 1.1).
We have collected maps and other documentation needed for planning a
construction of perforated sewage outlet, as well as water chemistry data of the
WWTWs for reference to monitoring in Actions C1 and 2 and for planning the
demonstration for part of the discharge in Hämeenlinna/Paroinen WWTW. Flow
measurements and wastewater discharge flow simulations have been planned to
take place during the ice-cover of the lakes and will be conducted as soon as the
lakes freeze over, after which the most representative monitoring points can be
determined. The flow measurements have been delayed due to late winter but
that will not affect our objectives. The description of monitoring points is
connected in the proposal to M 1.1 (due date 31 January 2014) incorrectly, as the
selection of monitoring points is based on flow measurements conducted during
the winter 2014. The demonstration sites will be described together with the flow
directions of the monitoring sites by 31 December 2014 (M 5.1 and M 6.1).
A2: We have contacted the Regional State Administrative Agency (AVI Western
and Inland Finland) and found out that we should apply water permit for the
demonstrations conducted in Keuruu and Petäjävesi (D 1.1). We have contacted
water protection associate of Kokemäenjoki, which has preliminary agreed to

prepare the documents needed for water permit application. We have been in
contact with ELY-Häme about the need of permit for demonstration in
Paroinen/Hämeenlinna WWTW. Due to differences in the effluent discharges
and the use of only part of the discharge in the demonstration in
Paroinen/Hämeenlinna WWTW, we probably do not need a permit. We will
check that from AVI Southern Finland shortly when the detailed plan for the
demonstration has been prepared.
5.1.2. Action B
B1: Lake modellers of SYKE attended a discussion with researchers of UJ and
LBS of choosing demonstration areas. To enable measurement of representative
monitoring points and construction plan for extended perforated sewage outlet,
scuba diver chased down, checked the spatial construction of and marked the end
of waste water discharge pipe with buoy in Keuruu and Petäjävesi on 15
November 2013.
We decided to conduct the first demonstration action in Keuruu WWTW in
summer 2014 and the second one in Petäjävesi WWTW in summer 2015. The
construction plan for the extended perforated sewage outlet was ordered from
Pöyry PLC (section of Waste water treatment plants, contact persons Antti
Harinen and Eeva Ronni) and was delivered at the end of January 2014.
In Paroinen WWTW located in Lake Vanajavesi, the demonstration site was
visited and lake sediment, as well as both lake water and WWTW outlet water,
was sampled for preliminary analysis. Water discharge from Paroinen WWTW is
different from that in Keuruu and Paroinen, as the treated wastewater is released
to a small stream (Rautamonoja) draining into a shallow bay of Lake Vanajavesi,
instead of being led through a discharge pipe deeper in the lake. This allows us to
test a different approach in the N-SINK demonstration in order to extent the time
the treated waste water is in contact with lake sediment: part of the discharge of
Rautamonoja is led through a pipe on the shallow sediments and the perforated
sewage outlet is covered with filtration fabric to prevent treated effluent water
immediately to be mixed in the lake water. To be able to estimate the
effectiveness of this approach we will use watertight fencing around the sediment
filtration area and measure the difference in chemical constituents between inlet
and outlet water. Land owner under the influence of our demonstration action
was found out and contacted and his attitude was very positive. We will start the
demonstration in Paroinen in summer 2015.
B2 and 3: SYKE together with MTT organized a workshop for researchers
(M4.1, on 19 December 2013 in SYKE), where a plan on how to combine
catchment, lake and economical models to calculate cost effective allocation of
nutrient abatement measures at watershed level was made. Shortly, catchment
and lake models will provide information on nitrogen retention and nitrogen
loading, which is needed to economic model, which will form the main part of
the tool. We decided that the main agricultural scenarios to be modelled are
based on current agri-environmental programme. We are in time with these
actions.

5.1.3. Action C
C1: Baseline denitrification activity, dissimilatory nitrate reduction, N2O and
other ecosystem parameters have been monitored bimonthly in Keurusselkä and
the monitoring will continue. First monitoring in Petäjävesi will be done at the
beginning of February 2014.
C2: In Paroinen/Lake Vanajavesi we will start monitoring during spring/early
summer 2014.
UJ, LBS, DPHYS and SYKE kept a meeting concerning the monitoring and
modelling actions of the demonstrations on 20 January 2104 in Jyväskylä.
We have plans to apply additional external funding for the most expensive
analyses in Action C1 and 2, due to the shortage in our budget caused by the cut
off in the late phase of the application process, and use the results in the project.
The analyses, in which the external funding is needed, are for denitrification and
N2O, which both are crucial in estimation the effectiveness of our demonstration
actions. One possibility is to apply funding from FIWA; the next call open for
proposals until the end of February 2014.
5.1.4. Action D
For communication and dissemination, we opened project www-pages (D8.1;
http://www.helsinki.fi/lammi/NSINK/suomi.html) on 20 September 2013. All the
reports, instructions, appearances in media etc. documentation are shared among
partners, stakeholders and all other interested individuals in www- pages. We
organized starting seminar on 1 November 2013 at LBS, with 24 participants
(D8.2; Annex 7.2). University Communications and Community Relations gave
a press release about the project and two general public articles have been
published: one in the local newspaper and another in the customer magazine of
Hämeenlinnan Seudun Vesi Oy. The presentation about the project was given in
the Mid-term Workshop on CAS – AF Cooperative Projects in Peking, China (24
October) and at a local Riihimäki-Hausjärvi Rotary Club (18 November 2013).
We have submitted two abstracts about the project to be presented in the
European Geosciences Union General Assembly on 27 April – 2 May 2014 and
the 13th
International Conference on Urban Drainage 2014 on 7 – 12 September
2014. LIFE+ notice board (Annex 7.2) has been drafted and will be printed after
all partners have given their comments on that.
5.1.5. Action E
Project coordinator was hired on 7 October 2013. We requested stakeholders to
nominate representatives in steering and advisory board on 18 October 2013 and
received the last nomination on 1 November 2013. The first SAB meeting was
organized on 12 December 2013 and it was held at Finnish Environment
Institute.
5.2. Availability of appropriate licences and authorisations
We will apply water permit for the demonstrations to be conducted in Keuruu and
Petäjävesi, but do not probably need one in Paroinen/Hämeenlinna, which will be
checked from AVI of Southern Finland.
Inception report LIFE+ 9
5.3. Envisaged progress until next report.
A1: Flow measurements and wastewater discharge flow simulations will be
conducted as well as the most representative monitoring points determined in the
selected demonstration sites.
A2: Water permit application will be send before the end of February 2014 (M 1.2).
B1: The extended perforated sewage outlet system will be constructed at Keuruu
following the construction plan. A scuba diver will install the filtration system in June
2014 if we get the water permit for the action.
B2: We will start to make a description and first analysis of observed water quality
data by using SYKE’s long time series (M 3.1 Description of monitoring data due to
30 June 2014). We will start to write description of the models and their combination
(M 3.3 Description of the models due to 30 June 2014)
C1: Monitoring of ecosystem effects will be conducted bimonthly in March, May,
July, September and November in both Keuruu and Petäjävesi.
C2: Monitoring in Lake Vanajavesi will start in spring – early summer 2014
D1: LIFE+ notice boards will be printed and set on display at all partners’ premises to
be visible to the public. Project www-pages will be improved and updated regularly.
E1: The second SAB meeting will be organized in 14 May 2014.
We propose new deadlines for Midterm (31 January 2015 → 31 March 2015) and
Progress reports (31 January 2016 → 31 March 2016) due to too long delay (i.e. 20
months) between the originally proposed deadlines of the last two reports. The new
reporting dates allow us to give financial reports over the full year, i.e. until 31
December. It would also ease the rush of our financial secretaries who are in the
middle of other financial statements in January.
