Mustapha MAHI, ONEP (ISO TC 224 / WG4)

Office National de l’Eau Potable (ONEP), Morocco

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Plan
  • Objectives
  • Scope, content and implementation

of the standard

  • Components of wastewater systems
  • Requirements for wastewater systems

management

  • Guidelines for the Management
  • Service Quality Assessment
  • Performance Indicators (PIs)
  • Use of PIs for Operation

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Objectives
  • The aim of this standard is to provide the relevant stakeholders with guidelines for improving the service and the management of water utilities,
  • facilitate dialogue among stakeholders including users, local or national water authorities, public or private water operators, non governmental organizations (NGOs) etc., so that the users’ expectations are better taken into account and the management of water utilities by the relevant authorities is more transparent;
  • Specify good practices for a better management of the water resources and the patrimony of the services;
  • Define quality assessment criteria and performance indicators enabling the results of the service delivered to be measured and compared with the objectives agreed upon between stakeholders;
  • Facilitate the monitoring of performance within a water utility.

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Very important
  • Use of these standards is voluntary in accordance with ISO rules.
  • The standards are sufficiently flexible and allow adaptation according to local, regional or national needs.
  • The object of the ISO 24511 standard is not to lay down systems of specifications supporting direct certification of conformity, but to give guidelines for continuous quality improvement of the management of the water utilities

Application of the standard ISO /TC 224 – WG4
  • Components of wastewater systems: paragraph3, annex B
  • Management components of a wastewater utility : paragraph 4, annex D
  • Objectives for the wastewater utility : paragraph 5, annex C
  • Guidelines for the management of wastewater utilities : Paragraph 6, annex C
  • Assessment of water services : Paragraph 7
  • Performance indicators(PIs) : Paragraph 8, annexes E and F

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Scope

This standard includes :

  • the definition of a language common to different stakeholders,
  • definitions of the characteristics of the elements of the service according to the customer expectations,
  • a list of requirements to be fulfilled for the operation and maintenance (management) of a wastewater utility,
  • a list of service assessment criteria and related examples of performance indicators, all without setting any target values or thresholds.

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Scope

This standard specifically excludes :

  • methods of design and construction of wastewater systems,
  • regulating management structure and methodology of wastewater service activities of operation and management,
  • regulating the content of contracts or sub-contracts.

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Components of wastewater systems
  • Collection, transport and treatment : Wastewater treatment can include centralised/decentralised systems
  • On-site-systems :

- treatment : pit latrine; septic tank etc.

- collection : small diameter, simplified

sewer

  • Reuse of wastewater : residue reuse/disposal

facilities.

  • Disposal of residues : sludge

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Types of wastewater Systems

Source : hydroconseil France

  • Density of the population
  • Level of social welfare (socioeconomic comfort)
  • Proximity of sanitations utilities (collection and transport by truck or by network)
  • Technical constraints: nature of soil, drinking water system etc.

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Management of wastewater utilities
  • Organization :

The wastewater utility should provide a well-structured documentation of its hierarchy and organization of workflow.

  • Planning and construction

The planning of the adaptation, the development and the construction of the wastewater system should be based on a long-term strategy for environmental protection, by improving step by step the wastewater system taking into account the population and urbanization development, the evolutions of the expectations, changes in the mandatory and legal requirements, the safeguard of public health and mitigation of flooding hazards.

  • Operations and maintenance

The wastewater operator should develop a plan for operations and maintenance strategy covering both proactive and reactive activities.

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Service assessment
  • Service assessment

Assessment is a process which, as every process, should be managed explicitly and clearly define the objectives of the process, the scope of the assessment, the responsible organization, the parties involved, the model or method to be followed, the resources needed, the frequency and activating event, and the users of the results.

  • Considerations relating to wastewater services

This standard is only a guideline; it is not a specification, the compliance with which one of the stakeholders could want to check. It is not a tool for certification, but presents general guidelines aimed at encouraging the definition and the implementation of good practices for the management of wastewater utility.

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Performance Indicators (PIs)
  • Performance indicators are used to measure the efficiency and effectiveness of a utility in achieving its objectives
  • Performance indicator systems should be considered as a key assessment tool among the various existing assessment tools
  • Performance indicators should be used within the context of a comprehensive service assessment system. This system should include, amongst other tools, a coherent set of indicators and the related components that allow for a clear definition of these performance indicators and assist in their interpretation.

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Performance Indicators (PIs)
  • … are tools to measure performances
  • … influence / regulate the whole business life
  • … not only limited to water and wastewater

management

  • Main questions concerning the use of PIs:
  • For which purpose?
  • Who creates the PI System?

– Utility itself

– User [e.g. via „user associations“]

– Authority/Regulator

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

PI Systems waswater

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

PI systems
  • IWA offers in the PI handbooks a large number (approx.150) of different PIs
  • Any PI System must be „tailor-made“ with regard

– to location, social circumstances, size,

economy

– to the questions to be answered

– to the problems to be solved

Note: “Data Collection” alone is not a “PI System”!

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Example of PI : Objective: Protection of public health
  • The main objective of a wastewater utility should be to ensure safe collection, treatment, disposal / reuse of wastewater for the protection of human health and safety.
  • Possible Service Assessment Criteria: Safe Discharge of Wastewater
  • Possible Performance indicator: Discharge from Wastewater Treatment Plants into the receiving bodies complying with discharge consents

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Example of PI : Objective: Provision of services under normal and emergency situations
  • sewer blockages Performance Indicator: Sewer blockages (No./100 km sewer/year)
  • Definition: Average number of blockages occurred per 100 km of sewers during the assessment period

Examples of other possible Performance Indicators related to Provision of continuous services under normal and emergency situations are:

- Number of properties affected by sewer malfunction overflows,

- Number of wastewater treatment plant failing permit limit,

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Example of PI : Objective: Sustainability of the wastewater utility
  • Performance Indicator: Total cost coverage ratio
  • Definition: Rate of total costs that are covered by revenues

WBI/InWEnt, Kampala, 24-27 July, 2007 - ISO Workshop

Example of PI : Objective: promotion of sustainable development of the community

Reuse of treated wastewater

  • Performance Indicator: Wastewater reuse (%)
  • Definition: Percentage of treated wastewater that is reused
