2. Water supply and recycling
2.1 Water supply system
The first supply outlet is enabled at a connection point with a pipeline owned by Zaragoza City Council which also supplies the area Garrapinillos. Plaza is supplied by a 500mm diameter pipeline, and this supply was to solve the most immediate needs, for companies in the First Phase. The pipeline runs parallel to the Canal before entering the Plaza enclosure.
The second pipeline, and main source of supply, is from its own outlet on the Imperial Canal. The Ebro Hydrographic Confederation acceded to the request by Plaza to the supply of 150 L/s, which unified Plaza with the Imperial Canal General Community of Users.
The water taken from the Canal is pumped through 4 x 220hp units to the reserve pools via a 900mm diameter ductile cast iron pipeline. There is also a second reservoir in the project, with a maximum capacity of 66,000m3, used to store flows when the canal is cut off.
The third supply point is a direct intake from the La Loteta pipeline providing Zaragoza. This is a branch of the large pipeline connecting directly with the reserve reservoir.
The water diverted from the La Loteta pipeline is pumped automatically, due to the variations of water level in the regulating tank and simultaneously with the start-up of the water treatment plant, which is always under load. Each pumping group has a capacity of 125hp.
After being pumped, the amount taken as drinking water is stored in a main reservoir of 125,000m3 capacity. From there, it is delivered to the water treatment plant, then stored in 2 x 2,500m3 concrete walls tanks covered with an aluminium sheet, equivalent to half the daily consumption.
2.2 River Ebro drainage
An internal outlet from Plaza runs through the Imperial Canal Linear Park between the retention basins and the northeast area of Plaza. It has a section of 2.5 x 2.5m, a length of 2,546m and a capacity of 12 m3/s.
The external outlet from Plaza runs from its northeast area to the River Ebro. The sections are 3 x 2.5 and 4 x 2.5m with a double internal pipe of 2.5m. The length of this pipeline is 5.475m, includes 2.203m of jacking with 2.5m of internal diameter and has an outlet capacity of 32 m3/s, divided between Plaza (12 m3/s) and Arcosur (20 m3/s).
2.3 Wastewater treatment plant
This has the capacity to supply 50,000 inhabitants and is destined for users at Plaza and the town of La Muela (Zaragoza). The purified water goes through a tertiary system for reuse as irrigation water in the parks at Plaza.
The use of wastewater for irrigation is made possible by these flows passing through a tertiary UV treatment stage to eliminate all bacteria.
2.4 Pump station 1
This is located in the Linear Park, next to the Imperial Canal, and has a pumping capacity of 900 m/s. This station is responsible for raising the flows from the Imperial Canal to the control reservoir.
2.5 Pump tubing
This connects the Imperial Canal intake with the control reservoir and has a diameter of 900mm and length of 4,950m.
2.6 Control reservoir
This has a capacity of 125,000m3.
2.7 Water purifier
This is the omnifiltration type with a capacity of 300 m3/h and the possibility of expanding to double that amount.
The filtration system consists of two stages: The first has an arrangement of two minerals, and the second, three others of different particle size in successive vertical layers. The treatment line is based on prechlorination followed by omnifiltration that includes injection of coagulant (alumina sulfate) at the entrance to the first filtration stage, a flocculant injection input at the second stage and a hypochlorite injection to disinfect the beds. The treatment flow is 167 L/s.
2.8 Drinking water tank:
Capacity of 2,500 m3.
3. Electrical energy
3.1 Electrical substation
For transforming to 220-132-45-15 kV. It has a total capacity of 240 MW divided into 3 x 80 MW transformers for voltages of 220/45 kV, 220/132 kV and 45/15 kV. The total investment in this infrastructure and in the associated distribution networks exceeded €11.3 million.
The facility was designed to feed Plaza; it receives the primary supply from the 220 kV transport network and is integrated into the 132 kV basic ring of Zaragoza, as well as those of Los Leones, Universitas, Miraflores, Casablanca and Torrero.
3.2 Logistics substation
Transformation of 45-15 kV. The large size of Plaza and the features and quality guarantee the supply must provide for the industrial developments planned in the enclosure made it necessary to complete the Platform electrical system with a new support facility of 45/15 kV, called the Logistics Transformer Substation.
The plant is located in the centre of the complex and has 4 line positions of 45kV and 7 positions at 15kV. It was constructed to gain efficiency in operating the network at this electrical node since, with its connection to the network, all the Platform distribution centres have a double power medium voltage supply.
Both substations and the associated electricity networks guarantee the power demanded from the primary network of 220kV, along with an additional support with interconnection to the Zaragoza 132kV ring.
4. Services and other information
4.1 Plaza has the following service networks:
- Stormwater drainage
- Sewage sanitation
- Drinking water
- Industrial water
- Gas
- Electricity (medium voltage)
- Telecommunications
Several telecommunication companies are expected to operate in Plaza, so a large amount of average size 110 mm tubing has been installed in the service area to house the different telecommunications operators to offer this service. There is a fibre optic network over a large part of the developed area, in addition to several telecommunication towers from different operators.
There is also a double drinking and industrial water supply network. The potable water network is treated at the Water Treatment Plant and supplies water for human consumption, while the industrial water network supplies non-drinking water for different uses, such as irrigation, fire extinguishing networks or industrial processes that do not require drinking water. This double network means there can be a differentiated tariff charged for the two types of supply for companies to adapt to their needs.
4.2 Other data
- Earthworks: 7,500 m3
- Aggregate: 177,000 tons
- H-30 concrete slabs for parking: 135,000 m2

5. Plaza road network
The main road in Plaza is Avenida Diagonal, which was the old N125 national road (currently A120) from the connection with the A2 motorway to Zaragoza Airport.
Continuing in the ascending kilometre direction, from the Trade Fair roundabout to the Airport, when leaving this roundabout the project has a section of about 44m wide, consisting of a road of 2 x 3.5m lanes and a shoulder of 2.5m. These roundabouts allow the passage of megatrucks (over 25m long).
There is also a service road in this section in each direction, with their corresponding hard shoulders, separated from the main road, to give access to the areas adjacent to the road itself.
Before arriving at the first Plaza roundabout, this service road joins the two lanes in each direction. From this first roundabout until the end, the roadway has a width of 26m and two lanes in each direction, hard shoulder and a central section of 4m, with the corresponding central shoulders of 0.5m each.
This is a road of 2,800m from which secondary roads lead off, making up a road network across the platform. The roads in Plaza are endowed with ample dimensions to allow for greater traffic fluidity. Large size vehicles can move comfortably around the wide roundabouts, with the main ones having a diameter of 109.5m internally and 130m externally, while the secondary have diameters of 79.5m internally and 100.1m externally.
6. Accesos
At present, Plaza has 3 different accesses, for greater connectivity with its surroundings. The main access is located at the south east area of Plaza, connecting the A2 motorway and the Z40 with the main road of the Platform.
This is a dumbbell interchange, which guarantees all the connection manoeuvres between the different roads. This access is also the entry point to the business area. In the northwest area, just opposite the main road of Plaza, there is a second access, next to Zaragoza Airport. This allows for direct connection to the airport, as well as the western area of Zaragoza city.
There is a third access in the southern area of Plaza that connects the A2 highway with the Zaragoza Air Base. This access point connects directly with the General Railway System.
