The objective of this paper is to identify, using a direct approach on a sewer length, the main source of organic solids among the different deposits and their erosion processes. The different deposits studied were large inorganic solids at the bottom of the sewer, biofilms on the walls of the sewer and organic solids at the water–bed interface. The method applied consisted firstly of analysing very precisely (mass and pollutant loads) the solids in the three types of deposits along a sewer line with a length of 150 m. Then, the deposits were eroded by in situ flushing experiments using tap water. Finally the nature and the mass of particles eroded along the length of the sewer were compared with the nature and the mass of solids in each type of sewer sediment in order to identify the main source of organic solids in the sewers. This comparison indicates that the organic layer at water–bed interface is the main source of eroded solids. An erosion test carried out under continuous observation confirms that the organic layer is actually eroded.</p></div>","PeriodicalId":101268,"journal":{"name":"Urban Water","volume":"2 4","pages":"Pages 305-315"},"PeriodicalIF":0.0,"publicationDate":"2000-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1462-0758(01)00012-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85361793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates how spatial and temporal fluctuations in rainfall can be incorporated into behavioural models, which simulate the performance of rainwater collectors. Temporal variations are considered at two different time scales, that is daily and monthly intervals. The first model uses a daily time interval to model system performance. A set of rainwater collector performance curves for five geographic locations is developed. From the location-specific curves, a set of average curves is determined which is shown to be sufficiently accurate for estimating rainwater collector performance. The second model uses a larger time interval of one month. The effect of daily fluctuations in rainfall is incorporated into this model using a storage operating parameter. Values of the parameter were determined by matching the output from the daily model with that of the monthly model. Generally the rainwater collector performance predicted by the monthly model using average values of the storage operating parameter is shown to correlate well with the corresponding values determined using a daily time interval model. The monthly model provides a simple and versatile method of modelling the performance of rainwater collectors.</p></div>","PeriodicalId":101268,"journal":{"name":"Urban Water","volume":"1 4","pages":"Pages 323-333"},"PeriodicalIF":0.0,"publicationDate":"2000-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1462-0758(00)00026-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82336330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this system, rainwater is recovered from the roof structure, collected and then used to satisfy part of the domestic cold water requirements of the supermarket (for toilet flushing). The design and commissioning of the system installed is first described. The system has been fitted with a monitoring system, which has been used to record the water usage and to estimate the rainwater recovered for use in the supermarket over approximately an 8-month period. The results are used to calculate the collection efficiency of the system compared to potential gains determined from local rainfall data. This data has also been used to calculate the revenue cost savings for this system. The additional capital cost of this system has been estimated and this has been used to calculate a payback period of 12 years, based upon a collection efficiency of 57.4%. Alternative payback periods for different locations in the UK are also discussed. Finally, this paper considers the effects of alternative roof and tank sizes on system economics. This shows that tank size is critical and that different configurations may be used to achieve payback periods approaching 4 years.</p></div>","PeriodicalId":101268,"journal":{"name":"Urban Water","volume":"1 4","pages":"Pages 345-354"},"PeriodicalIF":0.0,"publicationDate":"2000-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1462-0758(00)00032-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89189312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, empirically calibrated transport capacity relationships are used to estimate the movement of in-sewer sediments. The majority of these relationships were developed and calibrated with laboratory data sets that used uniformly sized granular sediment. In many combined sewers, there are both organic and inorganic sediments. The fine-grained organic sediments are thought to be able to develop considerable cohesive strength under certain conditions. This paper describes the results from laboratory experiments in which the erosion of non-homogeneous in-pipe sediment deposits was investigated. The types of sediment mixtures used ensured that a range of cohesive deposit strengths was developed. The measured bed load and suspended load were compared with transport capacity relationships currently used for sewer design. Significant divergence between the transport capacity predictions and experimental observations was discovered. It was seen that it is unwise to model in-sewer deposits as homogeneous and granular and that it is important to take into account the impact of deposit cohesion.</p></div>","PeriodicalId":101268,"journal":{"name":"Urban Water","volume":"2 4","pages":"Pages 285-294"},"PeriodicalIF":0.0,"publicationDate":"2000-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1462-0758(01)00007-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85958007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
