PROMOVER

Smart monitoring project of  combined sewer overflows

 

Year of implementation: 2014-2015

 

Background

The PROMOVER Project started in 2014 with an exhaustive state of the art elaboration about the existing regulations, parameters and technology for the draining point monitoring. Furthermore, we have focused in the analysis of the technology related to biosensors as pathogen detector device in the environment, the project’s innovative side.

When it came to the legislative framework analysis in Spain, the entry into force of the Real Decreto 1290/2012 was a clear turning point in the regulatory framework. The Ministry of Agriculture, Food and Environment modified the regulation of the Public Water Domain, from which a legal framework was created related to the overflowing of the sanitation systems when rainy weather. The RD1290/2012 establishes the requirement of the overflowing point list for the holders of industrial discharges and the holders of urban discharges with a population bigger than 50,000 equivalent inhabitants or 2,000 equivalent habitants in case of discharges to beaches or bathing water. Also, it is considered the provision of overflowing quantification systems for the draining points mentioned above.

 

Innovative Solution

The solution proposed by PROMOVER focuses on the quantification of combined sewer overflows (CSOs)in a sewer chamber of Zaragoza network through a real time monitoring of discharges duration, frequency and their quantitative and qualitative characterization measuring the following parameters:

  • Temperature gradient measurement for the discharge duration and frequency estimation and as a water quality characterization parameter.
  • Level measurement and flow estimation from the control section.
  • Turbidity measurement for suspended particles estimation.

 

The possibility to correlate quality parameters opens the door to a broader vision about the condition of the receiving environment. Additionally, it is required to look for some rationality in the variables and the equipment to use forgetting a smart control system (and thus low cost). Both working lines have been identified as a continuation of the PROMOVER project.

Living lab in the city

Within the framework of the Researching Project PROMOVER (Smart monitoring project of combined sewer overflows) funded by the Ministry of Industry, Energy and Tourism, a range of sensors was set up in a CSOs chamber belonging to the sewer network of Zaragoza.

In the project, led by Escuela Politécnica de La Almunia (EUPLA) also took part ECOCIUDAD Zaragoza, S.A.U. (municipal society responsible for city’s network management), ZINNAE and the companies AQUARA, Aqualogy and Alphasip.

The deployment of the sensors was led by personnel from Escuela Politécnica de La Almunia supported by Ecociudad Zaragoza, and supervised by the Drainage Management Department from Aqualogy.

The chamber is located in Plaza Carlos V in Zaragoza and drains to the Huerva River the discharges from the sewer system that exceed the capacity of the network. These overflow are originated when heavy rain occurs. The monitoring system is pioneer in Aragón and has been designed and implemented in EUPLA. This system allows to have information in real time about the relevant hydraulic variables (such as flows and CSOs duration) and about water quality.

The measures of the sensors are kept in real time. With the results taken from the project, we have been able to proper evaluate the impacts produced on the environment from sewage network during heavy rains.
