Construction of Water and Wastewater Infrastructure at the Polkowice Service Area (MOP) – S3 Expressway plus
Desc

The project involved the construction of water and wastewater infrastructure located at the Polkowice Service Area (MOP), as part of the S3 expressway development. The scope included comprehensive preparation of facilities to serve road traffic and technical support infrastructure along the express route.

 

Thanks to the applied solutions, the Polkowice MOP infrastructure was equipped with systems that ensure efficient water and wastewater management, operational safety, and compliance with the technical and environmental standards required for expressways.

Scope of work

Within the scope of this investment task:

 

    • the bodies and equipment for two pumping stations (PS and PD) were delivered,
    • pumping station equipment was installed and hydromechanical commissioning performed,
    • two DN 6000 tanks were delivered and installed: a firewater tank and a retention tank,
    • a BIOFIT 450 treatment unit body and equipment were delivered,
    • treatment plant equipment was installed,
    • hydromechanical and technological commissioning were carried out,
    • a high-efficiency coalescence separator with sedimentation (ESK‑H 30/3000 SEP K), two fat separators with sedimentation (EST‑H 4/800, designated SEP and SEP4),
    • a high-efficiency two-chamber vortex sedimentation tank with lamella inserts (EOW‑2L 40/400) was delivered,
    • two overflow and fat‑level alarms (EU‑AL PT), an oil‑level alarm (EU‑AL R), and an alarm for overflow, oil level, and sediment (EU‑AL PRO) were delivered,
    • a watertight wall-mounted enclosure (OH‑4B.3) with PG‑7 cable glands was delivered,
    • a DN 3000 well (ZB1) and a DN 2000 well (ZB2) were installed.

    • Applied solutions

    The project utilised well-established and reliable technologies and products, including:

     

    • BIOFIT 450 treatment plant – a compact, modular solution ready for integration into wastewater treatment systems, offering future expandability.

    • Ecol‑Unicon separators and settlers – provide effective retention of pollutants, including petroleum derivatives and fats. Key technologies include ESK (coalescence separator), EST (fat separator), and EOW (lamella settler).

    • EU‑AL PRO alarm system – monitors sediment, fat, and overflow levels, minimising the risk of failure and streamlining operation and maintenance.

    • OH‑4B.3 sealed enclosure – ensures full tightness and protects the installation from external environmental factors.

    • Retention manholes (DN 3000, DN 2000) – durable infrastructure components with high storage capacity, supporting effective stormwater management.
