Short-commings of first MPs

Missing or insufficient elements: MP Summary Summary for each chapter (Abstract) => key

results No clear separate lists of agglomerations No clear calculation algorithm applied for main

agglomerations following a standard pattern used for data costs base.

No clear CF priority list as a result of options analysis and prioritisation

2


Short-commings of first MPs

No specific definition of problems No clear maps for representation of the

agglomerations no clear phasing no transparent lists of investments no real options studied no clear, limited number of prioritisation and

selection criteria

MINISTERUL MEDIULUI ŞI DEZVOLTĂRII DURABILE ROMANIAA) Definition of agglomerations in

Master Plan

Identification of all agglomerations at county level (maps and data base)

“Clustering” of Agglomerations based on techno-economic assessment

B) in Feasibility Study

Detailed option analysis Preparation of final/detailed maps

and data base on selected agglomerations

MINISTERUL MEDIULUI ŞI DEZVOLTĂRII DURABILE ROMANIAInterpretation of “Definitions for

UWWTD”Scenario c):

Legal requirements (compliance dates article 3 and 4,5 UWWTD) defined by P.E. of each individual agglomeration

Treatment standard defined by P.E. Of biggest agglomeration. No legal requirement for tertiary treatment if all agglomerations in the “cluster” are below 10.000 P.E. However, other Environmental Directives to be considered (WFD, Bathing Water Directive)

11

MINISTERUL MEDIULUI ŞI DEZVOLTĂRII DURABILE ROMANIAInterpretation of “Definitions for

UWWTD”Scenario b):

Splitting one settlement in two parts (i.e. River crossing the town) is not allowed

Development of future population load to be considered

16


How to define an Agglomeration in practice

Define boarders for all agglomerations in the county (settlements very close to each other might be merged to one agglomeration => consider also future development)

Classification of agglomerations in categories Below 2,000 p.e. 2000 – 1,0000 p.e. Above 10,000 p.e.

Example RomanExample Roman

page 18

Example for Agglomerations – Detailed Definition of Boundaries



Analyse case-by-case based on the criteria such as: Distance between agglomerations and topography

(altitude) Population/industrial density (p.e./ha) Unit costs for investments (sewer, WWTP, etc.) Specific Investment Costs (in €/p.e.) and specific

Operational Costs (in €/p.e.) => NPV Others (i.e. Recipient water available, land for WWTP

extension, existing capacities, etc.)

19



Prepare option analysis for all agglomerationsconsidering criteria above) One single WWTP versus separate WWTP Storage tanks for small agglomerations / small

WWTP Etc.

Group individual agglomerations in “clusters” of agglomerations (=> scenario c in Definitions of UWWTD)

Prepare map on county level indicating: all agglomerations (3 categories according to size) agglomeration boarders (each single agglomeration) Boarder of “cluster of agglomerations” Existing sewer network Existing and proposed WWTP/storage tanks Existing and proposed sewer trunk lines and

pressure mains (interconnection of agglomerations) and main pumping station

Administrative boarders Rivers

26


Countywide defined agglomerations

Agglomeration Cluster

Examples for Agglomerations – County Level



Prepare data base for all agglomerations including (at least): Name of agglomeration Generated load (p.e.): total, existing, extension Compliance date Specific investment costs, operation costs and

NPV (€ / p.e.) Scoring rate for Ranking Total investment costs for wastewater

28


Selection of priority investments

Two step approach: Step 1: Mandatory criteria

Compliance date 2015 ROC established

Step 2: Ranking Size of agglomeration (highest weight) Health improvement Environmental improvement Efficiency improvement

29


Criteria for Ranking

30

N° CRITERIA INDICATOR

A Size of agglomeration and improvement of connection rate

Total generated load in Population equivalent

Additional load connected in Population equivalent

B Health Risk

B1 water supply system without adequate sanitation system Number of households connected to the water supply but not connected

to the sewer system (or individual/adequate sewer treatment

B2 Existence of sewerage network % of households connected to the sewerage network

B3 Physical condition of sewerage network % of sewer network highly depreciated or with insufficient capacity (high

exfiltration to groundwater, sewerage overflow, etc.)

C Environmental Pollution

C1 Surface water pollution: Existing central sewerage network with

no or inadequate wastewater treatment

% of collected wastewater load discharged without treatment to the

receiving water

C2 Groundwater pollution: Existence of adequate wastewater

collection and treatment facilities

% of total generated wastewater load (p.e.) collected and treated with

effluent quality compliant to UWWTD

Example for criteria and indicators for Wastewater


Investment Scenarios for priority investment

1. Low Scenario (priority investments up to budget limit given by MESD

2. Medium Scenario minimum investments to reach compliance until 2015

3. High Scenario extended investments including additional agglomerations with compliance date beyond 2015 proposed in phase I

31


Final Selection of Priority Investments

Discuss with MESD Investment SCENARIO (based on criteria and investment scenario)

Agree on agglomerations to be included in CF project

Prepare priority investment table (template for priority investment costs)

32

MINISTERUL MEDIULUI ŞI DEZVOLTĂRII DURABILE ROMANIAAgglomeration boarders for

selected Priority Investment Measures

Prepare detailed map for selected priority investment measures (Scale 1 : 25.000) Detailed boarders of agglomerations Cluster boarders Existing/Proposed Infrastructure

(WWTP, main sewers etc.) Review/confirm option analysis

33


Phasing of Investment Measures

Based on agreed priority investment measures:

Prepare Long-term investment table (template for long term investment costs)

Prepare Map with phasing of agglomerations (categorise in 3 main phases)

34


Approval by Local Authorities (LA)

Approval of LA on investment list is mandatory!!

Maps of agglomerations should be included in the Urbanism Plan (by LA)

FS might start in parallel with MP approval for the endorsed investments
