Optimisation for Sustainable Water ManagementOptimisation for Sustainable Water Management

EU funded Project: OPTIMA INCO-MPC

Partner:INTERGEO Environmental

Technology Ltd.- Greece

OVERALL OBJECTIVEOVERALL OBJECTIVE

To establish strategies for optimization of water demand-supply balance to guarantee

sustainable developmentas a major part of the multi-objective

optimization approach of the DSS-OPTIMA.

Issues to considerIssues to consider

A. Resource Identification and Quantification

(i) Conventional Rivers, streams, springs, lakesGroundwater (shallow and deep)

(ii) Non-ConventionalSea desalinationRoof water harvesting


Issues to ConsiderIssues to Consider

B. Existing Exploitation Strategies

(i). Dams, Weirs

(ii). Reservoirs

(iii). Boreholes

(iv). Treatment Plants

(v). Distribution Systems



C. Management & Economics(i). Demand-Side Management

Water Conservation Techniques• domestic wastewater reuse (non-potable uses)• irrigation water reuse, drip irrigation• industrial water recycling and reuse• domestic water conservation technologies


C. Management & Economics(ii). Supply-Side management



Issues to ConsiderIssues to Consider(ii). Supply-Side management practices

conjunctive water use elimination of fresh water release into sea

aquifer recharge and management framework reservoir management / evaporation prevention distribution network management

rainfall harvesting desalination

surface/Groundwater abstraction control surface/groundwater risk assessment etc……..



(iii). Cost recovery issues cost build-up (investment, O & M, design,

permitting, land use costs,….etc.) tariffs and charges billing and bills collection

(iv). Legal and financial mechanisms for sustainability



D. Existing Environmental Stress Stream flow changes Groundwater Overexploitation Water quality and land degradation Downstream impacts of dams and reservoirs

etc….



E. Access to water and Conflict in Demand Domestic user groups (urban, peri-urban, rural) Agricultural users Industrial users Recreation uses Navigational uses Ecological/environmental advocate groups



5. Water Technology Alternatives Efficiency Indicators(i). Performance

Water supply increase or water demand reduction

(ii). Cost Affordable investment and service costs

(iii). Reliability Life time


Expected OutputExpected Output

1. Database of existing In-Country Capacity for Water resources Management

WP 04 - TASK FRAMEWORKWP 04 - TASK FRAMEWORK

1. Identification of the significant water sector problems and objectives-goals of each CASE STUDY

2. DATA INPUT from WP case study partners

3. Ranking and dealing with CASE STUDY water issues

4. Development of suitable alternatives and constraints

5. Techno-economic database construction

6. DATA OUTPUT


Discussion-QuestionsDiscussion-Questions

1. CONCEPT

Examination of Water-Tech alternatives (Techno-econ assessment): - How much in detail….??On local or state catchments level??- Emphasize on DEMAND-consumption practices???- According to what % of water saving or % water supply increase,

different alternatives will be examined??.Who will identify the significance?

Including in the Assessment of Potential Benefits of management practices:

- Estimate the economic benefits of water quality improvement

(Water/Wastewater Treatment Costs Reduction etc..) …???? (eg

appropriate fertilization reduces groundwater nitrate pollution, thus less groundwater treatment required)


2. DATA REQUIREMENTS

Information input from case studies

We require data-detailed description/assessment on the current water management status of each case study, concerning:

- Driving Forces (eg Intensive agriculture )

- Pressures (eg. High water demand , use of fertilizers, etc)

- State (Water quantity or quality)

- Impacts (eg. groundwater level drop, High nitrate concentration)

in order to provide

- Response (eg. Pumping control, drainage reuse)


3. DATA INPUT


-Total Water Resources, exploitation, consumption, management, recovery

-Main water uses and Conflicts

-Water demand versus available resource

-Water demand per sector (agriculture, domestic, tourism etc)

-Permanent and/or Seasonal deficits

-Water consumption practices

-Water Quality and Water Supply issues

-Resources & population

-Water Demand trends

-Existing conservation practices

-Land Use maps

-Hydrographic network

-Existing Infrastructure

-Supply, service Economics

-Social issues

4. DATA OUTPUT

Techno-economic data set format…..???????? We will provide tables (for each case study) with water technology options accompanied with cost functions????

Type of Cost functions……???????? Available cost data…???Water supply services/pricing..??

Provide a GENERIC APPROPRIATE TECHNIQUE TABLE with equipment/infrastructure and cost functions and

couple it with a TABLE including Country Cost Adjustment Factors, assigned for each CASE STUDY..????
