The core of INGREENCI is the preparation of a Management Manual of Rain Water to be used for the irrigation of urban green zones, since this is to be the basic instrument for both the education of engineers and geotechnicians (functionary executives of the Municipality as well as privately-practising individuals) and the background for the preparation of studies concerning planting the flat roof of Thessaloniki City Hall and landscaping of 28th of October Street, using rain water management methods.

The Management Manual includes:

a. Defining the general – specific goal:
Integrated rain water management combines conventional handling of immediately removing rain water from the urban web (using a man-made system of pipes) with mild techniques, aiming at: a) reducing total run-off water volume; b) reducing run-off peak; c) using rain water for secondary uses of lower quality requirements; d) upgrading urban landscape; e) limiting nuisance due to insufficiency of sewage networks; and f) cleaning and, consequently, improving the quality of run-off waters.
Generally speaking, integrated rain water management aims at improving the quality of life in urban and semi-urban areas and promoting and highlighting a new ecologic model for development/growth.

 

b. Classification
Grouping practices in relation to the place of implementation (green sites, squares, unbuilt land plots, parking lots, free & open spaces within building blocks, school and church yards, dry river beds, avenues and streets/roads in urban and peri-urban areas, private spaces, sports grounds, planted flat roofs), the type of structure, the geotechnic features (gradient, sub-soil properties, drainage capacity, filtering), and the carrying capacity involved (in the case of supra-structures, green roofs, solar collector installations), etc.

 

c. Evaluation Procedure
Determining the criteria and weight of their participation in the evaluation of the techniques implemented:

  • Incorporation of rain water management in landscape planning;
  • Incorporation of rain water management in pre-existing natural drainage/run-off system;
  • Contribution to the protection against flood phenomena;
  • Potential for collection and reuse;
  • Protection of natural water systems within cities;
  • Creation of constructs of high architectural quality;
  • Effectiveness of the practice proposed for cleaning rain water from atmospheric pollutants;
  • Potential for implementation in densely populated districts;
  • Cost of construction and maintenance;
  • Cost/Benefit ratio;
  • Social consensus;
  • Additional environmental and social benefits.

 

d. Techniques of mild environmental rain water management
Recording techniques applicable for cleaning, transporting, storing, re-using and, generally, managing rain water in urban environments. Best possible description of designing and construction details, operation manner, cost, advantages and technique applications.

 

e. Applied plans of integrated rain water management for urban green zones
1. Focusing on applied plans of temperate regions, with general rainfall height and meteorological features typical of the Mediterranean climate;
2. Evaluation of practices on the basis of the criteria and the groups of methodological approach;
3. Full description of best practices per group (1-2 practices);
4. Simple reference to plans applied in other districts, not related to the Mediterranean landscape (with relevant literature reference access data).

 

f. The case of Thessaloniki
1. Specific adaptation of plans applied in districts with features similar to those of Thessaloniki;
2. Specific adaptation of good practices in districts with features similar to the ones related to the district of the rain garden (28th of October Street, with analysis of local hydrological conditions, and, to the extent this is feasible, with cost/benefit analysis;
3. Specific adaptation of good practices for planting flat roofs;
4. Evaluation and description of the best solution;
5. Indicating & proposing free & open spaces (preferably in degraded districts) of Thessaloniki, the ultimate aim being to implement the ecologic rain water management system and to create new green sites.

MANUAL FOR THE INTEGRATED MANAGEMENT OF RAIN WATER

The aim of creating planted (flat) roofs is to upgrade the environment, to improve the energy efficiency of buildings and to reduce energy consumption, as well as reduce rain water run-off.
Planting flat roofs is one of the techniques used for the ecologic management of rain water. On the one hand, the soil substratum acts as a filter which retains surface pollutants through natural processes, while, on the other hand, it reduces the run-off coefficient, i.e. the velocity at which water is removed from building roofs that have been planted, as well as the quantity of water running off into the sewage pipe system.
This Project task concerns the regeneration of the axis of 28th of October Street, from Vasilissis Olgas Str. to Delphon Str., while also implementing the principles of ecologic rain water management.
Despite the fact that 28th of October Street is one of the main street axes leading to Vasilissis Olgas Street, it is considered one of the most degraded sites from an aesthetic and functional point of view. This axis runs through an urban district of very dense construction, with surfaces that are impermeable to water (asphalt pavements, sidewalks, flat roofs on blocks of flats), without any free/open green sites. A typical feature is the absence of trees, mainly due to narrow sidewalks.
The great quantities of rain water surging downhill, when there is intense rainfall, often create intense flooding phenomena, mainly at the T-junction of this street with Vasilissis Olgas Str.
The aim of this demonstration application is to capture rain water using specific techniques and clean it from the pollutants it carries using natural methods. Furthermore, aesthetic and functional regeneration of the axis is sought, through new urban equipment and other interventions that will upgrade the district.
The goal of the demonstration application is to capture rain water through creating rain gardens and to clean it from the pollutants it carries using natural methods. Besides, the aesthetic and functional regeneration of the street axis is sought, through planting trees, creating flower beds to operate as rain gardens, widening sidewalks, introducing new urban equipment and other interventions that will upgrade the district.
The aim of planted (flat) roofs is to upgrade the environment, improve the energy efficiency of buildings and reduce energy consumption. Planting flat roofs is one of the techniques used for ecologic rain water management. On the one hand, the soil substratum functions as a filter and retains surface pollutants carried by rain water through natural processes, before the cleaned water is returned to the environment; on the other hand, the soil substratum reduces the run-off coefficient, namely the velocity at which the water is removed from planted building roofs, as well as the quantity of water drained into the system of sewage pipes.
Flat roof planting is to be performed in two sectors:

In Sector Α, which will be accessible and operate as a demonstration patch and an environmental education venue for school pupils visiting the City Hall;

and

In Sector Β, which will not be accessible to the public, but will be visible from all blocks of flats surrounding the New City Hall.

These include, among others:
• creating an interactive game;
• constructing a website;
• producing and distributing a printed leaflet;
• placing informative entries in the daily and periodical printed press;
• organising a day-meeting related to the content of the programme;
• planning and materialising two awareness-raising events on demonstration project tasks.
