Description du processus de traitement

NGO Forum use the internal expert and sector standard for upgrading or decommission of the FSM. In few cases NGO Forum has hired external contractor.

Following the sector standard and guidelines for upgrade: NGO Forum has few resources such as clean/filtering grabbles, clean the safety tank chamber, cleaning the inlet pipe and increase the level of mud for creating dike.

Resources temporally needed for upgrade/decommissioning : Enough Water, local vehicles for transporting in the hilly area through a necessary community consultation as well as permission from the Camp In Charge (CIC) and Site Management Service (SMS).

Mask, Hand Gloves, Gum Boot, Apron and Rake is used as PPE. We normally follow the standard rules for using PPE. Every dislodging volunteer is responsible for completing the task. And over them there is Assistant Engineer and CHP for the monitoring. One of the challenge is for ensuring the quality our Project Engineer has to supervise directly.

If we construct small sewerage borehole and increase secondary transfer station, safety tank then the cost will be reduced.

By constructing small sewerage borehole or transfer station, we can reduce contacts between staff and sludge.

Ensuring community engagement and engaging skilled volunteer’s can guarantee the sustainability of the plant.

Specific challenges:

• emptying frequency too high as a result it is difficult to maintain retention periods.
• leakage of convenes pipe
• quality of effluent water
• space in the camps is limited due to the number of people and topography
• landslides in the rainy season
