By: Luh Putu Kusuma Ririen (Balifokus)

Commissioning activity was held on September, 2012 in Sumbawa and West Lombok Regency was aimed to assess the aspects of financial and institutional management as well as the technical aspect of installation maintenance in each community.

Boal Village, Jorok Village, and Praya Village are three villages in Sumbawa Regency where BALIFOKUS conducted the commissioning activity mainly on financial and institutional management aspects of community independent group in each area. The results signified three community groups have been performing their proper management by certain variables include community financial accounting, regular retribution entry from the member of community, and other items which will be circulated principally to maintain the wastewater plants.

In West Lombok Regency, the commissioning activity was conducted to observe and assess the technical aspect of the wastewater plants. There were three locations (Jembatan Kembar Village, Terong Tawah Village, and Karang Bayan Village) where the community-based sanitation program of public bathing, washing and toilet facilities (CBS-MCK) has been running by the community since 2011. The assessment covered the five main components as part of the whole plants to be evaluated, such as the toilet (includes the washing and bathing areas), the piping system, wastewater installation plant, the disposal system, and biogas utilization. The additional assessment variable is documentation e.g. poster of operation and maintenance for users and the operator.

All of the three locations relatively indicated good performances for the quality of the existing installations, for example the condition of ventilation and floor drain (at the toilet, bathing and washing areas), piping system and the control chamber, all wastewater plant compartments, the depletion and disposal system, biogas utilization, and the electricity capacity. On the average each of wastewater plant in these three locations is capable to provide access for 200-250 people. About three of four toilets, bathing and washing areas were set up at each location routinely used by the community. Some recommendations were provided to the community group organizers related to maintenance efforts, e.g. routine control for the piping system (control chamber).
