Welcome to the source of life!

We care about the people and the environment in our area of operations. We are present in our customers’ lives every day. We are a regional water supply company owned by the city of Lahti, and we have been providing water supply services to Lahti residents for more than a hundred years.

Our primary task is to ensure that the water services in our area are high quality, safe and cost-effective. We supply our customers with groundwater only, which is quite unique in urban conditions.

Lahti and the surrounding areas produce more water than we consume here. There is enough water and our customers can enjoy it without worrying!

Lahti Aqua employs about 80 water supply professionals and specialists in various positions. Our highly-skilled staff members ensure that the quality of the groundwater remains first-class, from the water intake plant to the customer’s tap. We are also responsible for treating wastewater in as eco-friendly manner as possible and for returning the treated water back to the environment.

It is important for us to increase our customers’ awareness of the use of water and to offer guidance and instructions in all matters related to water supply if necessary. We’re glad that you’ve found our website.
