We don’t need them. We rarely have to install bottom drains or even recirculation vaults. Why?
Premier Ponds builds sustainable ecosystems that don’t need bottom drains. The ponds we build are mostly less than 4′ deep, which means a bottom drain isn’t needed. If one’s needed, it’ll be installed.
A bottom drain is not to be confused with underliner drainage systems, which remove water that might collect under the liner. This is only in yards in which the rainwater will run to the pond, causing a potential for water to go under the liner.
