Development of design documentation and obtaining a building permit based on it for the project entitled: "Installation of a heat pump unit using waste heat from the municipal waste water of the Central Sewage Treatment Plant in Gliwice". - is the task that Antea Polska S.A. will perform for PEC - Gliwice Sp. z o.o.

District heating faces a number of challenges in relation to the EU's climate policy, which includes achieving EU climate neutrality by 2050 and reducing greenhouse gas emissions to 55% in 2030.

The priority is to move away from burning the most emitting fossil fuels as quickly as possible and to integrate RES into district heating systems by developing district heating and cogeneration and improving energy efficiency.

Investment description

For this purpose, our client PEC - Gliwice Sp. z o.o. - will expand the energy infrastructure of the Central Wastewater Treatment Plant in Gliwice by installing a 12 MW heat pump system on its site, using the enthalpy of treated wastewater in the city's district heating system. 

Currently, the technical infrastructure of the wastewater treatment plant uses electricity generated from the combustion of biogas extracted from the treatment process, but does not use waste heat from the process.

The construction of the compressor heat pump unit will enable the waste heat from the discharged treated wastewater to be used for the plant's own needs and for technological purposes. It will also reduce the operating costs of the technical infrastructure and increase the utilisation rate of the existing cogeneration units. On the other hand, the produced surplus heat will be transferred to the municipal heat network of Gliwice, thus contributing to the management and use of waste heat in the infrastructure of PEC Gliwice in the process of decarbonising the production of system heat.

Scope of services provided

Antea Polska S.A. will participate in the implementation of this task. Within the framework of the contract signed with PEC - Gliwice Sp. z o.o., we are responsible for:

  • development of the project information sheet (KIP), 
  • development of project documentation with all necessary and required studies, arrangements, decisions and permits provided for by law, including: 
    • development of the building design including the land development plan (PZT), 
    • development of the architectural-construction design (PAB) 
    • development of all other documents necessary to obtain the building permit (without the technical design) 
  • obtaining the final building permit decision, 
  • preparing a draft investment implementation schedule,
  • determination of estimated total investment outlays and outlays for each stage of the investment implementation, 
  • development of the functional-utility programme in order to conduct the tender procedure for the design and execution of construction works based on the design documentation,
  • preparation of answers to the contractors' questions,
  • execution of possible changes and modifications to the design documentation and the functional-utility programme.

The planned investment will contribute to improving the efficiency of the district heating system of the City of Gliwice.
