Drinking Water Supply System: Installation Of Approx. 60 Drinking Water Distributors, Various Tapping Points And Approx. 18 Standpipes. The Individual Components Can Be Connected Using Pe Pipes As Well As Flexible Hose Lines With A Total Length Of Approx. 2,500 Meters. Some Areas Of The Event Area Are Fed By Just A Single Hydrant, Meaning That Increased Installation Effort Is To Be Expected. In Order Not To Have A Negative Impact On The Flow Of Visitors, Drinking Water Pipes Sometimes Have To Be Laid Over Roads And Walkways Using The Building Construction Process, Which Is Why Cable Bridges Should Be A Minor Alternative When Laying Pipes. In Some Positions The Route Of The Pipe Is Predetermined For Planning Reasons, So The Client Must Be Involved In The Pipe Planning. Wastewater Disposal System: Since There Is No Possibility Of Discharging Wastewater Directly Into The Public Sewer Network In The Event Area On The North Side, It Is Necessary To Set Up A Wastewater Pumping System Over A Distance Of Approx. 700 Meters. A Wastewater Disposal Facility Must Be Created Every 30 Meters For The Approximately 60 Food Stalls In This Area. On-Call Service: From The First Installation Of Water-Bearing Components, We Require 24-Hour Availability. During Opening Hours, It Is Essential That An Assembly Team Is Permanently On Site To Carry Out Maintenance Work.
