Depending on where you're getting your water, the initial fill for your pond is going to be the biggest expense. After that, you'll need to top it off to account for evaporation, splashing losses if you have a waterfall, and other small miscellaneous losses. The biggest post-installation water stealer is a leak that can continue for weeks or even months before it's detected, located, then repaired.
You can reduce the risk by monitoring your pond levels - if you're seeing more loss than is normal for the season, take action before that bill arrives! Our comprehensive pond guide can help you start looking for evidence of leaks.
