WEDAs activities are internally separated between three sectors:

Commercial Pool Sector design, build and sell pool cleaners for swimming pools and commercial swimming facilities with high demands on performance and reliability.

Industry sector design and develop underwater cleaning equipment for tanks and reservoirs in industries like Nuclear Power stations, glass works, steel works, pulp and paper facilities etc.

Water & Services Sector design and develop underwater cleaning equipment for water works and wastewater treatment plants. We also offer on-site cleaning and inspection services.

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.

Industry sector design and develop underwater cleaning equipment for tanks and reservoirs in industries like Nuclear Power stations, glass works, steel works, pulp and paper facilities etc.

Weda has delivered and installed cleaners in nuclear power plants, glass factories, fish farms, gypsum plants, pulp and paper mills and several other applications where there is a need for cleaning (sludge removal) without having to drain the water.

Weda has a unique experience and know-how from more than 50 years activities in the development and production of products for under water use. WEDA´s Industrial division is aiming to find solutions for all applications of cleaning under water may it be with existing products, products that need to be customized or new products designed in cooperation with the client.
