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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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. READ MORE

  3. 12. Design and development of an automated rat trap for sewage system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Vallabh Venkatachalam; [2021]
    Keywords : Rat trap; automated trap; sewage systems; mechanical rat trap; Råttfälla; automatiserad fälla; avloppssystem; mekanisk råttfälla;

    Abstract : This thesis report describes the design and development of an automated rat trap for sewage system. This rat trap has been designed to have a working duration of 2 months or approximately 15749 hits with trap dimensions length 535 mm, width 430 mm and a height range of 931 – 1151 mm with respect to different sewer pipe diameters.

  4. 13. Olika trädsubstrats vattenhållande kapacitet och dräneringsförmåga : en jämförande studie

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Michael Barone; [2021]
    Keywords : ekosystemtjänster; träd; växtbäddar; dagvatten; skelettbäddar; substrat; biokol; pimpsten; dränering; fältkapacitet;

    Abstract : I takt med klimatförändringarnas framfart, med bland annat högre temperaturer och mer extrema skyfall, riktas det alltmer fokus på de reglerande ekosystemtjänster som träden kan erbjuda oss i det urbana landskapet. För att träden ska kunna leverera de ekosystemtjänster som efterfrågas krävs att de når en hög ålder och därmed också större volymer i krona och stam. READ MORE

  6. 15. Sensitivity analysis of grate inlet representation and a comparison of two coupled hydraulic models for urban flood simulation

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Daniel Lundqvist; [2020]
    Keywords : Urban flood models; 1D-2D coupled models; MIKE FLOOD; FLO-2D; inlet grates; manholes;

    Abstract : Urban flood models are an important tool in designing and analyzing municipalities sewer drainage systems and predicting the effect of potential extent and depth of future floods. In urban areas, coupled 1D-2D flood models are particularly useful as they can represent the surface- and sewer system and their interactions. READ MORE
