forming the Commission shall be selected among technicians specialized in
water matters.
Article 2 – Mandate
1. The mandate of the Commission shall be to propose a
yearly aquifer utilization programme which, as far as possible, takes into
account the needs of the various users. To this effect, the Commission shall
be entitled to formulate any useful proposal on the measures to be taken in
order to ensure the protection of the waters in the aquifer and to remedy
possible causes of pollution thereof.
2. The Commission shall in particular give its technical
opinion on the construction of new extraction works on the aquifer and on the
modification of existing equipment.
3. The Commission shall proceed with the audit of the
construction and operational costs of the recharge installation as further
specified in Articles 12 and 13 of the present Arrangement.
4. Each delegation shall report to its parent authority.
Article 3 – Organization
1. Each party shall assume for itself the running costs
of the Commission.
2. The Commission, as necessary and on an equal basis,
shall designate representatives entrusted with the control of the volume of
water extracted by the various users.
3. The Commission shall convene periodically, as well as
whenever so requested by either of its member delegations.
4. The meetings of the Commission shall be held
alternatively in Geneva and in the Sub-Prefectorate of St- Julien-en-Genevois.
5. The conclusions of the Commission’s meetings shall
be recorded in a joint report.
SECOND CHAPTER – Waterworks and Equipment
Article 4 – Inventory
1. All existing waterworks and their equipment, whether
public of private, allowing for the utilization of the resources of the
Genevese aquifer shall be inventoried jointly at the initiative of the
Commission.
2. This inventory shall detail all the specific terms and
conditions currently governing such waterworks, such as the authorized water
extraction volume, the installed power and protected areas.
Article 5 – New Waterworks and Equipment
1. Every new waterwork or equipment, as well and any
modification to existing waterworks and equipment, shall be subject to the
prior technical opinion of the Commission as provided for in Article 2.2
above.
2. Subject to the provisions of the present Arrangement,
the respective parent authorities of the parties hereto shall make sovereign
decisions in respect of the projects submitted to them.
3. The inventory provided for at Article 4 above shall be
up-dated every time new waterworks and equipment are set into operation.
4. The Commission shall oversee the construction of the
waterworks and equipment referred to at paragraph 1., above, until the same
are set into operation.
Article 6 – Recording of Water Extractions
All waterworks shall be equipped with a device for the
recording of the volume of water extracted from the aquifer. Such a device
shall be periodically gauged and sealed at the initiative of the Commission,
each of the parties hereto having its own seal. Readings shall be effected
periodically and recorded in a register kept in two originals.
Article 7 – Recording of Water Levels
1. All waterworks shall be equipped with a standard
device for the recording of the variations in the water-level of the aquifer.
2. Copies of the recording tapes shall be remitted
periodically to the operator of the recharge installation who shall be
designated by the State of Geneva and who shall present his report at least
once a year to the Commission.
THIRD CHAPTER - Construction and Operation of the
Recharge Installation
Article 8 – Construction – Operation – Ownership
1. The Republic and Canton of Geneva shall be responsible
for the construction and operation of the artificial recharge installation
which shall be and remain in its sole ownership.
2. It may entrust the operation of this installation to a
third party, hereinafter designated as the “operator”.
FOURTH CHAPTER – Extraction Forecast – Limitations
Article 9 – Limitations
1. Based on the dimensions and capacity of the artificial
recharge installation to be constructed, the French authorities and public
collectivities shall ensure that the aggregate of water extractions by the
users located within their territory shall not exceed 5’000’000 cubic
meters per annum, inclusive of a free allocation of 2’000’000 cubic
meters. In case of necessity, derogations to this 5’000’000 cubic meters
limit may be agreed to by the Commission upon consultation with the operator.
2. In exceptional circumstances and in order to be able
to satisfy their own needs, the Swiss users may request the French users,
through the Commission, to forfeit part or whole of their free allocation in
their favour. Upon acceptance by the French users, the effective water volumes
allocations shall be paid for by the Swiss users at the cubic meter production
cost obtained from similar French waterworks, payment conditions being
specified at the time of the request.
Article 10 – Forecasts – Reserved Water Volumes
1. In order to ensure the rational management of the
recharge installation, at the beginning of the year each user or group of
users shall announce to the Commission their estimated volume of extractions
from the aquifer for the next twelve months. Such forecasts are designated as
“reserved water volume”, or:
rv
2. The “total reserved water volume” equals the total
of the reserved water volumes by all users, or
Rv = rv 1 + rv 2 +
… rvn
3. The operator shall take Rv into
consideration in order to best manage recharge operations, each user being
entitled to dispose with priority of the reserved water volume (Rv)
allocated to him.
4. Each user or group of users shall be entitled to a 20%
extraction margin with respect to his reserved water volume (Rv).
Extractions in excess of 20% over and above Rv shall be subject to
the approval of the Commission based on the technical opinion of the operator.
CHAPTER FIVE – Recording and Control of Extractions and
Water Levels
Article 11 – Definitions
1. (Ev) shall mean the volume of water
effectively extracted in one year by the aggregate of French and Swiss users.
2. The recording of water extractions from the aquifer
shall be effected jointly and entered into two registers, one for the Swiss
authorities and one for the French authorities.
3. Water level data from the aquifer shall be exchanged
and recorded into those same registers. These may be inspected at any time
upon request by either of the two delegations comprising the Commission.
CHAPTER SIX – Artificial Recharge Cost Sharing
Article 12 – Definition of Construction Costs
1. Within one year at the latest from the setting into
operation of the recharge installation, the State of Geneva shall compute
corresponding construction costs in Swiss Francs. Such construction costs
shall include in particular:
- study
costs and fees directly related to the construction of the installation
and ancillary works;
- the
total cost of the construction works as such (civil engineering,
electro-mechanical equipment, buildings, drainage network, landscape
works);
- electro-mechanical
equipment start-up charges.
2. The parties hereto covenant and agree that investment
costs shall be amortized in constant yearly installments (A), computed
interest included, over a period of thirty years taking into account the
subsequent variations in the money market rates. In this connection, the
interest rate shall be fixed every year based on the borrowing conditions
obtained by the Genevese public collectivities from the ‘Banque hypothécaire
du canton de Genève’ (Mortgage Bank of the Canton of Geneva).
Article 13 – Definition of Operating Costs
Operating costs (O), computed yearly, shall include the
following items expressed in Swiss Francs:
- power
supply;
- chemicals;
- treatment,
elimination and disposal of sediments;
- labor;
- spare-parts
and various materials;
- maintenance
of buildings and access ways;
- transport
and related costs;
- management
and insurance costs;
- replacement
of part or all of the electro-mechanical equipment as considered
technically indispensable by the Commission;
- rental
cost of the land supporting the recharge installation.
Article 14 – French Participation
1. The French participation (Fp) to the artificial
recharge costs shall be computed yearly as follows:
Evepf
Fp = (A + O) -------------
Vr
in which:
Evef
= Effective volume of water extracted by the French users;
Evepf
= Effective volume of water extracted and payable by the French Users
= Evef – 2’000’000 cubic meters (free allocation);
Vr = Volume of recharge water extracted, i.e., Ev less
natural recharges currently estimated at 7’500’000 cubic meters per
annum, which estimate may possibly be revised by the Commission based on
observations made in the course of operations.
It is nevertheless expressly agreed that, in order to
compute the French participation, a reduction in water extractions from the
aquifer occurring for whatever reason on the Swiss side shall in no instance
lead to a value of Evfp: Vr higher than the said natural recharges, i.e., 2 :
7.5, unless allowed by the Commission in accordance with the provisions of
Article 9.1., herein.
Volumes of water not extracted but paid for to the State
of Geneva by Swiss users shall however not be accounted for as a reduction in
water extractions from the aquifer on the Swiss side within the meaning of the
above paragraph.
2. In the event that the effective volume of water
extracted by all French users (Evef) would be lower than 70% of their total
reserved water volume (Rvf), the French participation to recharge costs shall
nevertheless be computed within the limits established at paragraph 1., above,
by adjusting the value of Evef to 70% of Rvf (Evef = 0.7 Rvf).
Article 15 – Form of Payment
1. At the beginning of the year, a contribution
proportional to the reserved water volumes shall be paid in advance; such a
payment shall guarantee a water level in the aquifer sufficient to satisfy the
normal operation of all waterworks during the year.
2. A the end of the year, the State of Geneva shall
establish the balance of the total French and Swiss participations for
consideration by the Commission. Upon notification of the amount of the French
participation contemplated at Article 14 above, the balance due after
deduction of the advance provided for at paragraph 1., above, shall be paid
within sixty days in Swiss Francs to the Treasury of the State of the Republic
and Canton of Geneva.
SEVENTH CHAPTER – Quality Control – Pollution
Abatement
Article 16 – Water Analysis
1. Water extracted from the aquifer shall be analyzed by
both sides on the basis of standard qualitative analysis criteria established
by the Commission.
2. Such analyses shall be made at regular intervals, as
fixed by the Commission. Results shall be exchanged and recorded.
3. Analyses of the water intended to be injected into the
aquifer shall be made under the same conditions.
Article 17 – Warning System
1. The parties hereto shall maintain a monitoring network
installed at the initiative of the competent local authorities and intended
for the issuance of warnings in the case of accidental pollution likely to
affect the water quality of the aquifer.
2. In case of warning, protection measures commensurate
with the circumstances shall be taken on both sides without any restriction.
EIGTH CHAPTER – Liability
Article 18
1. The Republic and Canton of Geneva shall be liable for
damages caused to the quality of the waters of the aquifer resulting from
failure to maintain the recharge installation or from want in its operation,
especially as regards water treatment.
2. Its liability shall however be exonerated in the event
it can be evidenced that such a pollution would have occurred even in the
absence of a recharge installation.
3. The liability of the French and Swiss public
collectivities or of third parties in the case of pollution of the waters of
the aquifer resulting from acts or events occurring within the French and
Swiss territories is reserved.
NINETH CHAPTER – Term and Termination
Article 19
1. The present Arrangement is concluded for a period of
thirty years.
2. Unless either party hereto serves a notice of
termination to the other party at least one year prior to expiry, the present
Arrangement shall automatically renew for five year periods.
3. Either party hereto shall be entitled at any time to
request the opening of negotiations with a view to modifying or supplementing
the present Arrangement. Such negotiations shall initiate within six month
from the date of the request at the latest.
TENTH CHAPTER – Disputes
Article 20
1. Any dispute relating to the implementation of the
present Arrangement shall be submitted for conciliation to the Franco-Genevese
Regional Committee.
2. Failing settlement, the matter shall be referred to
the Franco-Swiss Consultative Commission for Problems of Neighborliness.
ELEVENTH CHAPTER – Final Provisions
