GPP CRITERIA FOR WASTE WATER INFRASTRUCTURE


2

Background GPP CRITERIA FOR WASTE WATER INFRASTRUCTURE

Objective

To provide public authorities with adequate guidance to meet the environmental legal requirements, effective technological alternatives, as well as to inform them on best practices through the development of GPP criteria for the EU green public procurement of wastewater infrastructures

Outputs

Technical background report including: › Analysis of the proper wastewater treatment to fulfill existing regulations

› Key environmental impacts/contribution to resource efficiency

› Analysis of the different wastewater infrastructure technologies/scenario include including Life cycle cost (LCC) methodology

EU Green Public Procurement criteria with core and comprehensive criteria for each scenario

The GPP criteria for wastewater infrastructure works will be developed for: › Construction/renovation of collecting systems

› Wastewater treatment covering different level of treatment methods and technologies incl. treatment of sludge

Step 1Preparation of Technical Background Report

Step 2Development of GPP Criteria

Step 3External Consulation

Step 4GPP Advisory Group Consultation

Step 5Inter-service Consultation

Step 6GPP Criteria Adopted


4

The application and use of GPP criteria for waste water infrastructure is quite different from other GPP criteria. The reason is that these GPP criteria relate to:

1. Big and often complex infrastructure

2. An area with different levels of legal requirements (EU and national) for the effluent depending on actual location of the projects and the environmental sensitivity of the receiving water bodies

3. Projects that themselves are having a positive environmental impact compared to a situation where the project is not implemented. Still the discharge of the remaining content of substances is the main contributor to the overall total potential environmental impact from wastewater treatment plants

Main challenges GPP CRITERIA FOR WASTE WATER INFRASTRUCTURE


5

Key environmental impact GPP CRITERIA FOR WASTE WATER INFRASTRUCTURE

The main environmental impacts/effect categories linked with wastewater treatment plant projects are:

› Nutrient enrichment

› Toxicity

› Global warming

› Acidification


6

Key environmental impact GPP CRITERIA FOR WASTE WATER INFRASTRUCTURE

Key Environmental Impacts GPP Approach

› Energy consumption especially in the

operation phase

› Purchase equipment with low energy

consumption/high energy efficiency

› Increase the energy efficiency of electricity

and heat producing units

› Reduce energy consumptions in buildings

› Promote use of renewable energy sources

› Emission of nutrients with the treated waste

water

› Emission of pathogens and or hazardous

substances (e.g. heavy metals,

pharmaceuticals, organic priority substances

etc.) with the treated waste water

› Favour the waste water treatment efficiency

of the treatment plants

› Emissions from sludge incineration › Favour the flue gas treatment efficiency of

the sludge incineration plants

› Water consumption › Incentivise the reduction of water

consumption

› Promote reuse of water and use of grey/rain

water


7

Construction materials

At present, it appears not possible to give recommendations on the procurement of green building materials and construction products in the framework of the GPP criteria on waste water infrastructure projects

Reference to other relevant GPP criteria

The following GPP criteria for other product groups can be relevant to include in tendering of the administrative buildings of a waste water infrastructure:

- Office building (to be adopted in early 2013)

- Indoor lighting

- Heating systems

- Sanitary tap ware (taps and showerheads)

- Office IT equipment

- Toilets and Urinals

- Paints and varnishes (to be adopted in 2013)

Other environmental impacts GPP CRITERIA FOR WASTE WATER INFRASTRUCTURE

Selection criteria:

Depending of the specific wastewater infrastructure project the selection criteria can include one or more of the following experience and technical capacities:

› Experience in planning and design of waste water infrastructure (specific items within sewer systems, waste water treatment and sludge treatment should be specified)

› Experience in incorporating energy efficient process equipment

› Experience in environmental impact assessment and environmental management including incorporation of measures to reduce the total environmental impacts from discharge of waste water into the receiving water bodies

› Experience in performing Life Cycle Assessment (LCA) and ability to prioritise potential environmental impacts

› Experience in setting up and calculating Life Cycle Cost (LCC)

GPP criteria for consultancy services GPP CRITERIA FOR WASTE WATER INFRASTRUCTURE


10

Selection criteria:

Depending of the specific waste water infrastructure project the selection criteria can include one or more of the following experiences and technical capacities:

› Experience in construction of waste water infrastructure with focus on reduction of environmental impacts (specific items within sewer systems, waste water treatment and sludge treatment should be specified).

› Experience in operation of waste water infrastructure with focus on reduction of environmental impacts (specific items within sewer systems, waste water treatment and sludge treatment should be specified)

› Experience in environmental management of a construction site

11

Technical specifications:

› The overall energy demand of the wastewater facility is lower than the maximum defined in the technical specification

› Minimum standards for specific process equipment

Core award criteria:

› Lower energy consumption than that demanded in the technical specifications, based on the overall energy demand for the entire wastewater facility, for some selected specific process equipment and/or for buildings

Comprehensive award criteria: › Lower energy consumption than that demanded in the technical specifications,

based on the overall energy demand for the entire wastewater facility, for some selected specific process equipment and/or for buildings

› % of self-production of power and heat

Energy performance requirements GPP CRITERIA FOR WASTE WATER INFRASTRUCTURE


12


› Demands on effluent standards › Demands on maximum chemical consumption

Core award criteria:

› Treatment efficiency for different pollutants such as BOD, nitrogen and phosphorous › Sustainable use of precipitating chemicals

Comprehensive award criteria:

› Treatment efficiency for further pollutants such as pharmaceuticals, pathogens, heavy metals and organic priority substances

Wastewater treatment efficiencies GPP CRITERIA FOR WASTE WATER INFRASTRUCTURE

Demands on water efficiency demand for specific treatment units and equipment. Award criteria go beyond that, including rainwater and grey water use: › Additional points will be awarded for water savings measures that goes beyond the above

mentioned specifications

Water consumption GPP CRITERIA FOR WASTE WATER INFRASTRUCTURE


14


› Demands on emission standards for: Dust, HCl, SO2, NOx) Core award criteria:

› Additional points are given for reducing the emission of the substances listed above below limit values for pollutants for sludge incineration.

Comprehensive award criteria: › Additional points will be awarded - in addition to the core criteria - treatment

efficiencies for more substances e.g. mercury, PAHs, cadmium and zinc

15

› LCC covers all costs in each life cycle (see Figure)

› Core criteria: Financial LCC without the external costs

› Comprehensive criteria: LCC is suggested to an economic assessment where the externalities are included.

› The coverage of external environmental costs will be limited to what is feasible for a given project.

LCC definitions
