1. Overview of the Tender

Purpose of the Tender

Acosol S.A. has issued a tender for both monitoring and rectification of odour issues at two key wastewater treatment locations in the Estepona sector:

  • Guadalmansa Wastewater Pumping Station (WWPS)
  • Guadalmansa Wastewater Treatment Plant (WWTP)
  • Residual Water Pumping Station (RWPS)

The objectives of the tender are:

  1. Regulatory compliance with environmental standards.
  2. Monitoring and reducing odours.
  3. Improving environmental conditions and worker safety.
  4. Implementing ozonification systems for odour treatment.

This initiative is financed through the Canon for the Improvement of Hydraulic Infrastructures in the MMCSO territorial scope, as published in BOP Málaga nº 204.

2. Scope of Work and Equipment Requested – Total €375,678

The contract includes both monitoring and rectification measures:

Monitoring Equipment (Lot 1-4) – €111,713

  • Outdoor air quality monitoring (H₂S, NH₃, VOC sensors).
  • Gas sensors for various locations.
  • H₂S sensors in water.
  • Air flow meters to evaluate ventilation efficiency.

Rectification Work – €263,964.75

  • Ozonification System Installation to treat odours at WWTP, WWPS, and RWPS.
  • Supply of ozone generators (200 g O₃/h capacity).
  • Air and water dosing systems for pre-treatment and biofilters.
  • Installation of control equipment and sensors to monitor ozone levels.
  • Integration with SCADA system for real-time monitoring.
  • Specific improvements at RWPS, including enhancements to ventilation systems to reduce odour accumulation.

3. Monitoring and Rectification Process

How Monitoring Will Work

  1. Continuous measurement of gaseous emissions.
  2. Integration with SCADA systems for tracking.
  3. Automatic alerts when gas levels exceed thresholds.
  4. Data storage for long-term analysis (minimum two years).
  5. Evaluation of odour reduction effectiveness after interventions.

How Rectification Will Work

  1. Installation of ozone generators to neutralize odorous compounds.
  2. Dosing ozone into air and water at key locations.
  3. Air circulation improvements to prevent gas accumulation.
  4. Monthly reporting on system performance.
  5. At RWPS, improvements to ventilation will mitigate trapped odours.

4. Budget Analysis: Rectification vs. Monitoring

The total budget across the tender is €375,678.

CategoryEstimated Cost (€ excl. VAT)Percentage of Total Spend
Monitoring Equipment (Lots 1-4)€111,71329.7%
Ozonification System (Rectification)€263,964.7570.3%

Key Finding:

  • A substantial budget has been allocated to odour treatment, not just monitoring.
  • Ozonification aims to actively reduce odour emissions at the wastewater sites, including RWPS.

5. Mention of Ventilation System at Residual Water Pumping Station (RWPS)

The tender does mention rectification work at RWPS, which includes ventilation improvements.

Current Situation

  • The RWPS facility currently has inadequate ventilation, contributing to odour accumulation.
  • The tender includes enhancements to ventilation systems, ensuring better air circulation and gas dispersion.

Recommended Actions

  • Ensure the proposed ventilation upgrades effectively mitigate odour accumulation.
  • Integrate air filtration (e.g., activated carbon filters) to neutralize odours.
  • Incorporate monitoring data to adjust ventilation dynamically and optimize efficiency.

6. Final Summary and Recommendations

Findings

✅ Monitoring and rectification measures are both included.

✅ Ozonification system installation aims to actively treat odours.

✅ Ventilation improvements are planned at RWPS to address odour issues.

✅ Monitoring will confirm the effectiveness of odour reduction efforts.

Next Steps

  1. Confirm that monitoring is used to assess and refine rectification efforts.
  2. Push for follow-up assessments to determine ongoing odour control needs.
  3. Ensure ventilation improvements at RWPS are implemented effectively.
