Disadvantages: Open drains designed to carry wastewater invariably also carry stormwater, which is likely to cause problems for downstream treatment facilities. They may smell and the presence of the drain reduces the usable width of the street. Silting and frequent blockages with rubbish and construction debris are likely in collector sewers and covered drains to which open drains connect. Children may play with the raw sewage.
