1 A Case Study on Integrated Urban Water Modelling using Aquacycle NTUA, 2007

2 Contents Motivation Input Data Requirements Case Study - Greater Athens Area Model calibration and validation Formulation and simulation of urban water management scenarios Recommendations 2

3 Why Integrated modelling? Integration of water use and natural processes Respect of all water sources in the water cycle Integration of all components of the water system Sustainable and equitable use of all water resources 3

4 Why Integrated modelling using Aquacycle? Holistic view of the urban water cycle through a conceptual representation of system components: Water uses Water supply Wastewater treatment Integration of: Rainfall-stormwater runoff network Potable supplywastewater network 4

5 Aquacycle Features Not geographically explicit but it can handle spatial and temporal patterns for the various urban water uses Ability to simulate decentralized water and wastewater management Quantitative estimates of water use, stormwater and wastewater production Performance assessment for the entire system and alternative schemes ( what-if scenarios) 5

6 Structure of the Aquacycle Model

7 A daily urban water balance model Indoor water usage Climate Meteorology Site characteristics Daily urban water balance model Unit block scale operations Indoor water consumption Garden irrigation Stonnwater runoff Wastewater discharge On-site stonnwater and wastewater use Output Cluster scale operations Daily iterations for each cluster Road runoff Public open space irrigation and runoff Inflow and infiltration Leakage of imported water Groundwater recharge and base flow Community stormwater and wastewater use 7

8 Temporal and spatial scale Temporal Daily time step Monthly and annual estimates through the aggregation of daily data Spatial Unit Block: e.g. single household, industrial site, public building, commercial unit Cluster: Group of uniform Unit Blocks (e.g. local neighborhood, suburb) + roads + public open space Catchment: Group of Clusters (possibly of different characteristics) Garden Roof Road Unit Block Cluster 2 Pavement Open Space Cluster 1 Unit Block Cluster Catchment Cluster 3 Catchment 8

9 Data Requirements

10 Input Data 1. Indoor water use profile For the different water uses in a house (kitchen, laundry, bathroom, toilet) and household occupancy Prediction of the total water used in indoor activities 2. Meteorological data series Daily precipitation Daily potential evapotranspiration The length of available record data defines the maximum modelling period 10

11 Input Data 3. Unit Block, Cluster & Catchment description data (measured parameters) Related to physical catchment characteristics Values are determined through measurement, observation or local experience 11

12 Input Data 4. Calibrated parameters for stormwater, wastewater and water use User should provide initial values Values should be adjusted for fitting observed data on water supply, wastewater and stomrwater flows 5. Characteristics of applied technical options (e.g. stormwater and wastewater reuse methods) 12

13 Case study: Greater Athens Area

14 Case study: Greater Athens Area Overview Capital of Greece Population of 3,894,573 inhabitants(2001), accounts for 30% of country s total population It is about 400km 2 divided into 4 prefectures Athens has a typical Mediterranean climate Mean annual temperature 18.5 o C Mean annual precipitation 388mm Serviced by water supply network (1,700,000 metered connections) Wastewater network Separate approximately 95-98% Combined stormwater and sewer system in the city centre It is served by a WWTP 14

15 Case study: Greater Athens Area Athens water supply system includes: Surface water 4 reservoirs The Mornos reservoir and the Yliki lake hold 88,5% of the overall storage capacity (equal to 1400 hm 3 ) Groundwater resources More than 100 boreholes 350 km of main aqueducts 15 pumping stations 4 Water Treatment Plants The Athens water supply system 15

40 Recommendations

41 Aquacycle limitations (1/2) The model does not address short-term changes in water use, which in turn affect water supply requirements and wastewater production Does not provide for population changes (e.g. during the summer and holiday seasons) Does not provide for temporal variation in the profile for indoor water usage (e.g. increased washing and showering during the summer season) It is not an event-based model Estimates the total (daily) quantity moved through the urban water cycle Does not estimate peak flows or produce event hydrographs 41

42 Aquacycle limitations (2/2) Long-term simulation The model does not include the possibility to develop scenarios for urban expansion/population growth Water needs are always covered by imported (fresh)water - Simulation under water shortage conditions and water cuts? Indoor water use The typical unit block of a cluster (and therefore the entire cluster) can have only one indoor water usage profile Indoor water usage profiles are differentiated only according to the average household occupancy and not per cluster The model does not take into account technology improvements that result in water saving (e.g. high-efficiency washing machines, lowpressure taps, dual-flush toilets etc.) Technology applications On-site technologies are applied at the household level, implying that each household is a single house Block flats? Cost and water quality estimations are not included in the package 42
