  1. 1. Predicting inflow and infiltration to wastewater networks based on temperature measurements

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Martin Åsell; [2024]
    Keywords : Inflow and Infiltration; I I; CNN; Linear regression;

    Abstract : Sewer pipelines are deteriorating due to aging and sub optimal material selections, leading to the infiltration of clean ground and rainfall water into the pipes. It is estimated that a significant portion (up to 40-50%) of the water entering wastewater treatment plants is actually clean infiltrated water. READ MORE

  3. 2. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Adnan Asif Rifat; [2023]
    Keywords : Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

    Abstract : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. READ MORE

  4. 3. Moving towards a proactive sewer pipe inspection approach : A state-of-the-art analysis

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ataul Hakim Mahamud; [2023]
    Keywords : Sewer failure; Inflow; and infiltration; CSO; Blockage; prediction model; proactive; Avlopps Fel; Inflöde och infiltration; CSO; Blockering; prediktionsmodell; proaktiv;

    Abstract : The failure of sewer pipes is a significant issue that can adversely affect the environment and public health. The problem is exacerbated by the additional burden it places on treatment plants, which must work harder to process the increased sewage flow resulting from pipe failures. READ MORE

  5. 4. Modelling of Inflow and Infiltration into Wastewater Systems with Regression and Random Forest

    University essay from KTH/Matematik (Avd.)

    Author : Viggo Steen Danielsson; [2022]
    Keywords : Regression; random forest; wastewater systems; rainwater infiltration; rainwater inflow.; Regression; random forest; avloppssystem; trög regnpåverkan; snabb regnpåverkan.;

    Abstract : The aim of this thesis was to evaluate the validity of statistical modelling, with regards to flow in wastewater systems based on precipitation. A wastewater system, which is a system of pump-stations connected via pipes, is affected by precipitation as rainwater enters the system. READ MORE

  6. 5. Hydrological modelling of a recycling facility and landfill

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Mazen Tawfik; [2022]
    Keywords : Parsimonious approach; Lumped modelling; Surface water; Landfill; Leachate water; Storage reservoirs.; Technology and Engineering;

    Abstract : A parsimonious lumped model for simulating a catchment composed of a landfill and recycling facility were developed. The modelling results showed an acceptable conformity with the observed values with NSE of 0.54 and R2 of 0.56 in hourly simulations, though the results were characterized by a general underestimation.
