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

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Martin Åsell; [2024]
   Nyckelord :Inflow and Infiltration; I I; CNN; Linear regression;

   Sammanfattning : 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. LÄS MER

3. 2. Developing a Geographical Information System for a water and sewer network, for monitoring, identification and leak repair - Case study: Municipal Water Company of Naoussa, Greece

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Konstantinos Sourlamtas; [2023]
   Nyckelord :Water and sewer network; GIS; UAV; surveying; photogrammetry; orthophoto; geodatabase; Earth and Environmental Sciences;

   Sammanfattning : This thesis presents the design and implementation of a Geographic Information System (GIS) for the Naoussa Municipality Water and Sewer Company for better water utility management. The methodology contained field data collection like the valves, sewer manholes, hydrometers, and hydrants in two ways, UAV photogrammetry, and traditional surveying, the georeferencing process, photogrammetric processing, the digitization of old paper maps and the geodatabase design.

4. 3. Optimering av spillvattenflöden

   Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

   Författare :Filip Berglund; [2022]
   Nyckelord :Optimization; Wastewater network; Optimal control; Pumping system; Optimering; Spillvattennätverk; Optimal styrning; Pumpsystem;

   Sammanfattning : This thesis aims to produce a control strategy that minimizes the energy usage of the pumps in the sewer system of Växjö City. The pumps are located in a small number of pumping stations. These are connected by a network of pipes in a way that requires the control of the pumps to be coordinated, both within and between the pumping stations. LÄS MER

5. 4. A Nonlinear Reservoir Model to Simulate Blue-Green Stormwater Systems – An Application to Augustenborg Catchment in Malmö, Sweden

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Emmanuel Ekwu; [2021]
   Nyckelord :Blue-green stormwater control; Nonlinear reservoir routing model; Stormwater; Modelling; Calibration; Water engineering; Technology and Engineering;

   Sammanfattning : The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. LÄS MER

7. 5. How can Inflow & Infiltration be effectively and sustainably managed? : MCA as a tool for decision support in planning Inflow & Infiltration

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Erika Qvick; [2021]
   Nyckelord :Inflow and infiltration; stormwater; sewer system; sustainable urban water management; decision support; multicriteria analysis; Tillskottsvatten; dagvatten; avloppssystem; hållbar urban vattenhantering; beslutsstöd; multikriterieanalys;

   Sammanfattning : Inflow and infiltration (I/I) water in the sewer network originates from groundwater, precipitation, seawater as well as over-leakage from drinking water pipes. It is the proportion of water in the sewer system that is not wastewater and causes problems both at the treatment plant as well as in the sewer network. LÄS MER
