Course 2: TRANSFER AND TREATMENT OF HUMAN EXCRETA AND GREYWATER
Unit 3: Storage and transport
Expected Study Load : 8 hours.
This Unit has 4 parts. Part A discusses the different forms of urine storage; Part B for faecal matter. Part C and D deal with one of the most difficult parts of source separation and ecosan: the transport. You can imagine that most of the urine and faeces is produced in the city, whereas the biggest opportunity for reuse is in the rural areas. Some solution has to be found there. Interesting work has been done in the Novaquatis project in Switzerland; you find the link below. Also the Compendium on Sanitation offers a nice overview of conveyance solutions; you will find the corresponding pages in the Assigned Reading material.
We will discuss the Compendium more in detail later in the course.
After completing this unit, you will:
- understand the challenges of storing and transporting urine
- be able to calculate urine storage tank volumes and know the parameters that influence sizing of urine storage tanks
- be aware of different types of faeces or faeces-water mixtures, collected from different types of toilets
- know different safe transport options for different types of excreta (urine, faeces, faecal sludge
