Where we are


AGS provides support services to improve the management and operational water and wastewater infrastructure processes.

Solutions


AGS develops solutions that deliver efficiency gains and generate value to water utilities.

Our aim is to spur technologies and reference methodologies in the sector, and establish a knowledge platform with our partners.

We implement engineering projects and tools to management support of urban water systems in the following areas:

Infrastructure Asset Management

How to manage infrastructures ensuring service quality for future generations?

Water Utilities challenges:

  • Long term service adequacy and reliability
  • Water and energy resources’ use efficiency
  • System’ risk management
  • Investment and operational efficiency optimisation
Infrastructure Asset Management Plans

Infrastructure Asset Management Plans assure infrastructures’ sustainability in the long term, leading to rehabilitation investments needs’ awareness to maintain adequate service levels, minimising risk and related costs.

Portuguese Decree-Law 194/2009 requires to water utilities the promotion and maintenance of an Infrastructure Asset Management system. AGS develops Infrastructure Asset Management system plans suitable to the context of water utilities, based on the approach adopted by ERSAR and provided for in the ISO 55000 standards.

Plans development approach followed:

Diagnosis

  • System global assessment
  • Available information identification

Plan development

  • Strategic level
  • Tactical level
  • Operacional level

Plan monitoring

  • Actions implementation support
  • Results analysis

Know-How

The approach adopted for the development of plans includes:

  • Water supply system assessment;
  • Hazards identification and risks characterization;
  • Control measures identification;
  • Monitoring procedures and corrective actions definition;
  • Routine management procedures;
  • Exceptional and emergency conditions management procedures;
  • Documentation and communication protocols definition.
