Polyzois Nikos S.A. is a construction company with more than 30 years of experience in design, construction, operation and maintenance of:

  • Water supply pumping stations.
  • Irrigation pumping stations.
  • Wastewater pumping stations operating with gravity network.
  • Wastewater pumping stations operating with vacuum network.
  • Wastewater treatment plants.
  • Water treatment plants.

Polyzois Nikos SA It has undertaken with complete success the design and implementation of a variety of pumping stations with design flow ranging from 1 to 30.000 m3/h and total head ranging fom 1 to 400 m.

The company has a specialized Department of Project designing and costing.

while all projects are designed in AutoCAD.

The mechanical equipment of the projects (hydraulic piping, pump bearing, etc) is assembled at the company’s premises and is installed thereafter on site.

This policy results in enhanced quality, greater speed and lower cost in constructing the project.

All completed projects are characterized by an impeccable quality of construction and low operational and after service costs.

The company follows closely the technological advancements and innovations in the fields of  pumping stations, wastewater treatment, water treatment, irrigation, etc, and has established itself as a pioneer in implementing them in Greece.

To that effect the company was the first in using the speed control system (inverter) in pumps in 2000; a practice that widely used nowadays. The speed control system offers great flexibility, efficiency and significantly lower operational cost at pumping stations.

Polyzois Nikos SA was also the first company that carried out the design and construction of the first large scale vacuum sewerage system in Greece, at the tοwn of Potidea, Chalkidiki in 2002. The vacuum sewerage system offers great advantages over the conventional gravity sewerage system, such as low depth of excavation, zero infiltration, better control and monitoring of the pipe network. The system has been fully operational and has displayed outstanding  results.

Additionally, the company was the first one in Greece to develop a large scale wastewater treatment plant using the membrane technology. The plant was constructed for the town of Agios Nikolaos, Sithonia, (with a population of 8.000). This technology is ideal in cases of small available space for the treatment plant and produces outstanding results regarding the quality of the treated water.

The company’s facilities are self owned - newly constructed in 2009, and fully equipped with self owned – state of the art mechanical equipment.

The company’s personnel is full time, permanent and has been working with us from periods ranging from 1 to 3 decades. The personnel is highly  specialised in all aspects of the operational field while it is continuously trained  in all relevant technological advancements and safety issues.

Personnel specialties include mechanical engineers, electrical engineers, chemical engineers, certified welders, plumbers, electricians, automation and control specialists.

Polyzois Nikos S.A .is accredited with quality certificates ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018.
