Sereco Board of Directors

The Board of Directors currently in office since 18/12/2018 is composed by Donato Ritella, Arianna Ritella and Tommaso Ritella

Our history

Sereco was founded on December 24th 1975 by Mr. Donato Ritella. At that time he was a young and brave entrepreneur who identified in the environmental protection and in the sewage and water treatment a potential sector, an environmentalist at a time when it was not fashionable to be.

The first years were dedicated to the development and construction of sewage treatment plants, particularly package plants for small and medium-sized communities. In the 1980s he began to design and build potable water plants. Starting from 1989, the main activity became the construction of special machines for water and sewage treatment. Thanks to the vast experience acquired in production, the supply to third parties takes became the main activity.

Already in 1998 the company looks beyond Italy and almost immediately finds a positive welcome in foreign markets and until today the company boasts supplies in more than 70 Countries. Already in 1997 SERECO implements quality management systems that allow it to obtain ISO 9001 certification.

The increase in the production requires a larger and equipped workshop. In 2006 the new factory of more than 20000 m2 opens. In 2011 the company celebrates its birthday with the opening of its fully renovated offices covering today 1200 m2 on three floor.

Design, innovate, implement, integrate, diversify: these are SERECO watchwords for the realization of its products. These words can turn into reality because SERECO is of experience and young company.

The average age of managers is only 45, an anomaly for Italy. The experts with more than 40 years activity in the sector of water and sewage treatment closely work with qualified young people mainly graduated at Polytechnic of Bari. There is a significant female presence at all levels of the company organization.

Sereco today

SERECO is specialized in the design and construction of plants, equipment and process machines for municipal and industrial water and wastewater treatment, water intake from sea, rivers and lakes. The company today offers the widest range among the Italian manufacturers in the water treatment sector.

Every equipment is realized on the original design developed by an internal team of engineers and manufactured in the company-owned factory, with a strong vertical integration of production process.

Sereco directly supplies its customers with a complete system of accessories and also of main and local electrical power, control and automation panels. This guarantees the perfect functioning of the equipment produced.

Sereco has a substantial presence in foreign markets, boasting production and supplies in over 70 Countries.

The factors that led to this result are:

  • business dynamics;
  • focus on quality;
  • focus on service;
  • focus on innovation.

The company builds collaboration with the customer right from the design phase, continuing in the executive, operation and maintenance phase.

The range of products offered can be completed with the process engineering service, even in the case of expansion and renovation of sewage and water treatment plants, both municipal and industrial, to offer its customers an increasingly satisfactory service.

Products and services

SERECO range of products is today wide and includes all process equipment for municipal and industrial water and sewage treatment plants as well as water intake from sea, rivers and lakes. All equipment are manufactured according to European regulation and in compliance with machinery directive 2006/42/CE.

The experience gained throughout the five continents, at every latitude, every temperature and every condition, struggling with different problems and requests allowed SERECO to gain unique know-how on the market and develop tailor-made solutions.

The catalogue here published however wide, it is not exhaustive of the variety of proposals but it represents a guide of the most widespread models and dimensions: a tool for designers, engineers, buyers and end-users, useful during selection stage, market research and preliminary proposals.

Each equipment is realized on original Sereco design created by the internal engineering team and manufactured in its own workshop to provide the highest product quality “from the cradle to the grave”.

Green Commitment

Green Commitment Our contribution in reducing CO2 emissions by getting pollution-free electricity from the sun.

As evidence of our continuous commitment to environmental protection, on August 2012, we have invested in the installation, on the roof of our shed, of a photovoltaic system that fits perfectly into the surrounding landscape.

The system with nominal capacity of 250 kW, expanded in 2021 with an additional 250 kW, make us completely independent from the national grid allowing us to be self-sufficient for the daily power consumption of offices and factory with reduced environmental impact.
