Worn-out sewerage systems result in an unnecessary impact on the water environment. Sewerage systems in bad condition lead to needless operational failures often resulting in flooding of basements, roads and public areas.
In addition, worn-out sewerage systems result in rats having free access to sewers through damaged pipes and poor joints. All of these situations create nuisances for the public.
NO-DIG renovationCOWI has a team of experts specialising in NO-DIG renovation, with wide experience of all kinds of trenchless technology methods, for example:
Investment in new sewersTo comply with environmental and operational requirements of modern systems for transport of wastewater, many municipalities are facing heavy investments in new sewerage systems.
Often, investments are targeted towards renovation of existing sewerage systems applying NO-DIG solutions. This is a result of the high construction costs involved in the establishment of new sewerage systems using traditional digging and trenches.
Tender projectsWhen tendering NO-DIG projects, COWI uses GIS-tools for the preparation of sewer layout plans.
Many projects also include TV inspection and hydraulic analysis. This provides the basis, upon which, the selection of method is decided in collaboration with the customer.
