About us

We help you with the right solution. Plastinject Watersystem AB, a sister company to Plastinject AB within the Lundahl & Hall group, develops and markets products for stormwater management. We specialise in solutions for the purification and attenuation of stormwater, and offer a wide range of heavy metal separators as well as market-leading stormwater cassettes, which we manufacture ourselves. Plastinject AB has been in operation since 1976 and became part of the Lundahl & Hall group in 2019. Together, the group has a turnover of 600 million SEK. Please feel free to contact us for more information, support with project design, or to view references.

Plastinject Watersystem

Our engagement is growing every day and our establishment in the Scandinavian market is successful. We have the market's broadest range with 9 different stormwater cassettes offering optimal flexibility and technical properties with thousands of references.

An increasing number of municipalities, clients, and contractors have also recognised our heavy metal separators, Hydrosystem, and our particle separator, Hydroshark. Several operational reference installations are available.

We can also offer oil separators, sealed tanks, and pre-fabricated rainwater systems with pump & filter, delivered plug-and-play.

Established products on the market such as grass pavers, simpler rainwater tanks, and downpipes with leaf filters in a vandal-proof design will, of course, remain!

    Manufactured in Sweden

    Our storage systems are produced at a fully automated factory in Anderstorp using 100% recycled material — an approach that is both cost-effective and environmentally sound.

    Efficient logistics

    Our products can be delivered either fully assembled or in flat packs. All unassembled products are stackable, which keeps transport to construction sites highly cost-effective.
