Filter Maintenance

Filter maintenance for the EcoVault® is simple. The addition of specially designed hatches to the EcoVault® makes them easily accessible for periodic inspections, vactor-truck service, or change(s).  In order for the filter(s) to perform as designed, it is recommended they be replaced either annually or semi-annually, depending on the local conditions, and as recommended by EcoSense. The cassette-style cartridges are recycled, inspected, cleaned, and refilled with the applicable media blend, reducing replacement costs. Quarterly inspection of the vaults is recommended to ensure the debris screens are not getting clogged with larger organic matter, and the chambers are not filling up with sediment.
