Basis: Ringsted Municipality has decided with the Wastewater Plan 2024 that jointly sewered catchments in Ringsted Municipality, including the city of Jystrup, must be separated and the rainwater from roads and roof surfaces must be led to the natural recipient, which in this case is Jystrup Lake and the Ålbækken. The existing joint system is of mixed compliance and was constructed between 1967 and 2010. The condition of the existing sewer system was investigated in 2009 in connection with the overall remediation planning for the entire city of Ringsted and in 2024 in connection with the preliminary studies for the current project. In 2014, the company Nielsen & Risager A/s (now Artelia) prepared a remediation plan with a description of the condition and recommended measures. This report is attached as an appendix to all tenderers and should be included in the consultant's considerations to the extent that it is considered appropriate. A new separate system is to be established. Based on the study in 2024, it is to be assessed to what extent the existing joint pipe can be reused. Reused either as a rainwater pipe that only takes surface water from the properties, whereby a new rainwater pipe for road drainage and a new sewage pipe must be established, or as a sewage pipe, whereby a new rainwater pipe for both surface water from properties and roads must be established. In this connection, it must be assessed and a plan made for the necessary lining, replacement or spot repair. New branch pipes must be established and where the existing common pipe is reused, it must be assessed to what extent, for example, the common pipe must be renovated/replaced. Separator wells are installed on all rainwater and sewage connections. Road drainage is connected and renovated as needed after further agreement with Ringsted Municipality. Public pipes located through private gardens must, as far as possible, be closed down and replaced by new pipes located in road/path areas. Private pipes that carry wastewater from several properties must, as far as possible, be replaced by new public sewer connections on the facade of the house facing the road. Any common connections between two properties must, as far as possible, be replaced by separate connections for each cadastre.
