Weda’s activities are divided into two separate sectors:

The Public Pool Sector – Cleaners designed for all types and shapes of commercial pools, aqua parks etc. The cleaners designed for ultimate cleaning performance and reliability with the highest level of automation.

The Industry Sector – Cleaners designed for all types of application within the industrial sector. From reactor tanks in nuclear power stations to large outdoor reservoirs for irrigation, cooling tower tanks, fountains, zoos, glass works etc.

Weda aims to offer the customers the best solutions based on cost, efficiency, reliability and environmental aspects for whatever the cleaning project may be.

Good water quality relies on regular cleaning. In collaboration with our customers, we constantly develop our products and services to fulfill their requirements for pump capacity, speed, handling and cleaning needs.

If there are specific requirements and needs that our standard products cannot handle we can help you by providing a customized solutions.

Weda’s products enable the clients to save energy and to minimize the use of chemicals.

Tanks and reservoirs can be cleaned without having to be drained and in most cases not even be taken out of service and production.

Since the start in 1919 we have built up a worldwide reputation for the highest quality and after sales service.

Our business idea is to offer all clients solutions and products for cleaning of all sorts of underwater surfaces. At the same time Weda aims to save energy and minimize the use of chemicals for its clients. Fresh water must be treated with care. We have limited resources in the world. Weda has become a creator of solutions for several clients around the world who has designed and built pools, water tanks and reservoirs. When they later put into use, it has proved that it often has not been so easy to clean and maintain. In cooperation with clients and partners like Veolia, Westinghouse and Stockholm Water Weda has developed cleaning robots for specific applications. Examples are water reservoirs, cooling towers and nuclear power plants. Public pools is still a major market for Weda. With a complete range of cleaners for public pools Weda has positioned itself as a producer of the highest quality cleaners in the world, and with a service network to back it up.

All types of sedimentation in water are not dangerous. If not removed however sediment may become a breeding ground for bacteria (E-coli, cryptosporidium, etc). Organic particles left on the bottom of pools in combination with high levels of chlorine may also be the cause of contamination such as cancerous chloramines. To remove the sediment, thereby making a better environment, is in short the purpose with everything we do at Weda. We minimize the waste of water and we assist in minimizing the use of chemicals in all sorts of water bodies.

The commercial pool sector

The commercial pool sector design, build and sell pool cleaners for swimming pools and commercial swimming facilities with high demands on performance and reliability.

Maintaining good water quality requires both effective water cleaning processes and effective underwater surface cleaning. Furthermore, effective surface cleaning means the amount of chlorine added to the water can be reduced. This contributes to a better environment for both employees and visitors. One of many advantages being a lower risk for allergic reactions.

2004 Olympics in Athens – An official assignment

During the Olympic Games, no detail is too small to be left to chance. The principal concern is the athletes’ wellbeing and the chance for them to do their best. Water quality is a significant factor to those whose arena is a swimming pool. Weda was chosen in tough competition with other suppliers to handle the pool cleaning during the Olympics. Weda was the only company that could fulfill the strict requirements for quality, reliability and service due to its outstanding products and the expertise of our local representative. We are naturally extremely proud of this official assignment and hope to have more opportunities to demonstrate our capacities and quality.
