  • On the preventive management of sediment-related sewer blockages: a combined maintenance and routing optimization approach

    In this work we tackle the problem of planning and scheduling preventive maintenance (PM) of sediment-related sewer blockages in a set of geographically distributed sites that are subject to non-deterministic failures. To solve the problem, we extend a combined maintenance and routing (CMR) optimization approach which is a procedure based on two components: (a) first a maintenance model is ...

  • Combined Sanitary Sewer Overflows (SSO) - Performance Focus: Fats, Oil and Grease (FOG) Reductio Case Study

    In-PIpe Technology Company, Inc., drastically accelerates the natural degradation of fats, oil and grease (FOG) in the collection system, thereby removing blockages and occlusions from the pipe and significantly reducing the occurrence of FOG-related sewer overflows, as well as the requisite equipment and manpower required for the physical removal of these blockages. Since In-Pipe started ...

  • How Much Could You Save by Avoiding a Consent Decree?

    In 2012, St. Louis, MO (Metropolitan St. Louis Sewer District) set a record for the most expensive sewer consent decree in history at $4.7 BILLION to be spent over the next 23 years. The cause of this consent decree and the cause of most consent decrees are overflow events that allow untreated waste into the nearby lakes, streams, river, or other nature areas. There are typically two types of ...

  • Chemical pretreatment of combined sewer overflows for improved UV disinfection

    The aim of this research was to better understand chemical pre-treatment of combined sewer overflows (CSOs) for subsequent ultraviolet (UV) disinfection. Approximately 200 jar tests were completed. Alum (Al2(S04)3·12H2O) resulted in a higher UV light transmission (UVT), and equivalent total suspended solids (TSS) removal, than ferric chloride (FeCl3). An ...

  • Estimating inflow to a combined sewer overflow structure with storage tank in real time: evaluation of different approaches

    The performance assessment of storage tanks and combined sewer overflow (CSO) structures in sewer systems requires knowledge of the total inflow from the catchment during rainfall events. Many structures are, however, only equipped with sensors to measure water level and/or outflows. Based on the geometry of the tank, expressed as a level-storage relationship, inflow can be calculated from these ...
