Still more often, municipalities, companies and private households experience flooding from the pipe systems due to heavy rainfall. The reason is that the huge amount of rainwater puts pressure on the pipe system which causes an overflow of mixed rainwater and wastewater.

Storing the extra amounts of water
Aarsleff has many years of experience in constructing reservoirs, including reservoir pipes that collect surplus rainwater and wastewater during heavy rainfall until there is sufficient capacity in the treatment plant. This prevents untreated water from flooding streets, gardens and other areas – and prevents water from being led into streams, lakes and the sea.

Reservoirs – from idea to establishment
Aarsleff is one of Denmark’s leading companies within establishment of reservoirs, which we usually carry out as turnkey contracts or as partnering agreements.

Aarsleff is a reliable business partner who is able to handle the entire project – from design and planning to excavation, sheet piling, tunnelling and concreting to the final instrumentation with manhole covers, stairs, gratings, flushing systems, pumps, control and electricity. We have considerable experience in designing and establishing open as well as closed reservoirs for rainwater and wastewater, and we can provide you with qualified advice on the most optimum solution.
