In order to understand the functioning of the internal drains and how to improve these, the following data are needed.
- Sizes of existing drains
- Materials used for existing drains
- Direction and functioning of existing drains
- Implementation methods, including who is in charge of finances, implementation etc.
For design purposes, the sizes and materials of existing drains are important to understand the network. To work towards a successful implementation, a good plan needs to be made to share the tasks such as finance and construction between YCDC, Ward Officer, local contractors, local residents, etc.
The multiple criteria analysis (MCA) is also made for the intervention and shown in the following table:
| Criteria | Level of impact (1-5) | Remark |
|---|---|---|
| Impact 1: high impact 5: low impact |
2 | large impact on flooding as water can flow easily, but depends also on larger system |
| Potential local ownership (by community/ YCDC) 1: easy to reach ownership 5: difficult to reach ownership |
3 | link with waste management campaign and cooperation with ward officer/ ward committees |
| Technical aspects – complexity 1: easy, uncomplicated 5: difficult, complex |
2 | some technical support needed |
| Implementation costs (project costs) 1: low costs 5: high costs |
2, 5 | Community financing – 2 project financing – 5 |
| Man hour costs (project team) 1: few hours 5: many hours |
2, 4 | community financing – 2 project financing – 4 |
| Implementation Time 1: little time 5: a lot of time |
3 | depends on Ward Officer and community |
