After Installation

Sustainable safe water access implies that communities can rely on a regular service which starts at completion of installation and continues over time. This period begins when the PVWPS is ready and available to users; it ends when the system is decommissioned because it can no longer serve its purpose. The activities described in Chapter 5 are meant to ensure the uninterrupted operation of the PVWPS and to guarantee that it effectively meets the users' long-term demands. While various options for monitoring a PVWPS are discussed, its normal operation is also described. The authors outline the most necessary operational and maintenance procedures and provide guidelines on spare parts replacement. While possible management schemes for the PVWPS are examined, the last section addresses how water usage at the PVWPS may evolve over its lifetime.
