Quantifying costs and lengths of urban drainage systems with a simple static sewer infrastructure model

摘要: A generic model is introduced that capable of quantitatively representing the combined sewer infrastructure a settlement. It consists catchment area module, which calculates length and size distribution needed pipes on basis rain, housing densities size. These results are fed into construction costs module in order to estimate entire area. The could be successfully fitted existing Swiss systems, indicating it can emulate their principal characteristics. also identify fundamental differences designs cities with historic roots. confirm there economies scale for systems Switzerland. modelling approach proved an effective tool understanding factors underlying cost structure water network infrastructures.
