Worldwide, two of the major causes of mortality and morbidity are unsafe water supplies and improper disposal of human excreta. Water and sanitation inadequacies also hinder economic and social development, constitute a major impediment to reducing poverty, and inevitably lead to degrading the environment. Unfortunately, the people in poverty stricken areas "especially infants and young children" suffer the most. This calls for appropriate solutions that are affordable considering local constraints. This course explores the possibilities of using small-scale decentralized solutions for poor, but also for rich countries. Through lectures and field exercises the students will be trained in design and implementation of rain water harvesting systems (collection, treatment and storage) fog water harvesting, design and protection of shallow wells and boreholes, design of spring sources, sizing of reservoirs, design of simple membrane filtration units, and small gravity water supply system for rural areas. For wastewater the focus will be design of natural systems (soil infiltration, wetlands, ponds) as well as source separating solutions. Keywords: soil infiltration, constructed wetlands, ponds, greywater treatment, biogas sanitation, dry sanitation, urine diverting and blackwater systems, package treatment plants, small diameter vacuum, pressure and gravity sewers.
The students shall be able to design small water supply systems based on groundwater or rainwater harvesting and select an appropriate solution for a given situation as well as design and implement small decentralized and source separating wastewater treatment systems.
The course is based on lectures, demonstrations/excursions
Depending on the selected cases. Revised annually.
GEO100, GEO220, JORD101, KJM100 and THT280 or THT282.
Lectures, fieldwork and excursions.
Written exam counts 50% and term paper counts 50%. Both parts must be passed.
Special requirements in Science
Reduction of credits:
Students cannot obtain credits for both THT281 and THT283. THT283 will be reduced by 5 credits.
