Final answer:
Water company records should include information on water purity, production rate, system lifetime, and costs, but not on electrical grid support since the village is off-grid.
Step-by-step explanation:
Water company records should contain all of the following information regarding the water system and its capabilities except details regarding electrical grid support, as stated by the requirements that the village is off the electrical distribution grid. The records should thoroughly document the purity of the water, the rate at which water is produced, and the lifetime of the system designed to supply the needs of a village or community. Additionally, they must include considerations about safety, environmental impact, design, fabrication, operation, and maintenance costs within the specified constraints. However, since there is no utility support due to the village's location, such detailed information about electrical grid support would be irrelevant in this context.
