We are very happy to have Lina on our team. The combination of her skills is extremely hard to find. We work in a fairly small industry, and many are competing to recruit people like Lina.
– Jakob Sjöberg, Founder & CTO at Swedish Hydro Solutions.
Knowledgeable, driven key player
Lina possesses broad expertise and an understanding of the industry that comes from experience. As an environmental consultant, she has seen the water treatment sector develop almost from the ground up to where it is today.
– In the past, water management was mostly about pumping water away. Twenty years ago, no one would have stopped production because of poor dewatering water quality. Now the requirements for water treatment have tightened, and they will continue to increase. Today, water can cause extremely costly stoppages, which makes it legitimate to invest more in proper treatment.
The issue of dewatering water will take on an increasingly important role in future earthworks and civil projects. The question is what can be done to strengthen that understanding even further.
– One step is that the Swedish Transport Administration, as a major client of infrastructure projects and a key driver for the rest of the market, as well as municipal environmental authorities, need to set the right requirements for water treatment. Contractors do what they must, so the requirements have to come from somewhere. It’s an ongoing process that has only just begun in Sweden. The requirements introduced in the Västlänken project are an early sign that the Swedish Transport Administration has started tightening expectations — and that dewatering water is beginning to take on a stronger role.
– Another path is for us at Swedish Hydro Solutions to build good relationships with contractors and help them understand the importance of water treatment — that it is a priority. For contractors, water in an excavation is simply a problem, a barrier to production. But with the right treatment technology, they can keep production running without water becoming an issue.
There is broad agreement across the industry — from regulatory authorities and municipalities to contractors and water treatment companies — that water treatment needs to be placed on the agenda early, and that all parties must collaborate across boundaries. This is especially important as requirements will only continue to tighten.
– Today, many projects do not take water treatment into account early enough. As a result, they do not plan for the space needed to manage dewatering water. The outcome is that many projects end up with very limited room for treatment equipment. Contractors need to consider water treatment already during the design phase, so that there is space for treatment later on. If water treatment is prioritized early, those cross‑functional conversations will happen naturally, Lina Hamel concludes.
