Wet Pond Maintenance Requirements
Important operation and maintenance procedures:
Immediately after the wet detention basin is established, the plants on the vegetated shelf and
- perimeter of the basin should be watered twice weekly if needed, until the plants become established
(commonly six weeks).
- No portion of the wet pond should be fertilized after the initial fertilization that is required to establish
the plants on the vegetated shelf.
_ Stable groundcover will be maintained in the drainage area to reduce the sediment load to the wet
pond.
If the pond must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain will be minimized as much as possible.
- At least once annually, a dam safety expert will inspect the embankment. Any problems that are
found will be repaired immediately.
- The measuring device used to determine the sediment elevation shall be such that it will give an
accurate depth reading and not readily penetrate into accumulated sediments.
After the wet pond is established, it will be inspected quarterly and within 24 hours after every storm event greater
than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance shall be kept in a
known set location and shall be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.

Minimum Requirements
The minimum requirements for Filterra Activation are as follows:
1. The purchaser must have procured vegetation meeting the requirements outlined in the Filterra
Activation Package.
2. The site la ndscaping must be fully stabilized, i.e. full landscaping installed and some grass cover (not just straw and seed) is
required to reduce sediment transport. Construction debris and materials should be removed from surrounding area.

3. Final paving must be completed. Final paving ensures that paving materials will not enter and contaminate the Filterra system
during the paving process, and that the plant will receive runoff from the drainage area, assisting with plant survival for the
Filterra system.

The Filterra Activation Package is available on the Contech website (www.ContechES.com/filterra) and ensures that the proper
conditions are met for Contech to perform the Activation service. Vegetation meeting Contech's requirements must be provided
at time of Activation. If the site does not meet the conditions required for Activation, or acceptable vegetation is not provided by
the purchaser at time of Activation, a charge of $1,500 will be invoiced to the purchaser.

Why Maintain?
All stormwater treatment systems require maintenance for effective operation. This necessity is often incorporated in your
property's permitting process as a legally binding BMP maintenance agreement. Other reasons to maintain are:
• Avoiding legal challenges from your jurisdiction's maintenance enforcement program.
• Prolonging the expected lifespan of your Filterra media.
• Avoiding more costly media replacement.
• Helping reduce pollutant loads leaving your property.
Simple maintenance of the Filterra is required to continue effective pollutant removal from stormwater runoff before discharge into
downstream waters. This procedure will also extend the longevity of the living biofilter system. The unit will recycle and accumulate
pollutants within the biomass, but is also subjected to other materials entering the inlet. This may include trash, silt and leaves
etc. which will be contained above the mulch layer. Too much silt may inhibit the Filterra's flow rate, which is the reason for site
stabilization before activation. Regular replacement of the mulch stops accumulation of such sediment.
When to Maintain?
Maintenance visits are scheduled seasonally; the spring visit aims to clean up after winter loads including salts and sands while
the fall visit helps the system by removing excessive leaf litter.
It has been found that in regions which receive between 30-50 inches of annual rainfall, (2) two visits are generally required;
in regions with less rainfall often only (1) one visit per annum is sufficient. Varying land uses can affect maintenance frequency.
Contributing drainage areas which are subject to new development wherein the recommended erosion and sediment control
measures have not been implemented may require additional maintenance visits.
Some sites may be subjected to extreme sediment or trash loads, requiring more frequent maintenance visits. This is the reason for
detailed notes of maintenance actions per unit, helping the Supplier and Owner predict future maintenance frequencies, reflecting
individual site conditions.
Owners must promptly notify the maintenance provider of any damage to the plant(s), which constitute(s) an integral part of the
bioretention technology.

The Filterra system will be (or has been)delivered to you with protection in place to resist intrusion of construction related sediment
which can contaminate the biofiltration media and result in inadequate system performance.These protection devices are intended
as a best practice and cannot fully prevent contamination. It is the purchaser's responsibility to provide adequate measures to
prevent construction related runoff from entering the Filterra system.
Included with your purchase is Activation of the Filterra system by the manufacturer as well as a 1-year warranty from delivery of the
system and a Final Site Assessment(assessment of unit condition, mulch replacement, debris removal, and pruning of vegetation)
scheduled between 6 months and 1 year after Activation, upon request.
Activation of the Filterra system is a procedure completed by the manufacturer to place the system into working condition. This
involves the following items:
• Removal of construction runoff protection devices
• Planting of the system's vegetation(provided by the purchaser)
• Placement of pretreatment mulch layer using mulch acceptable for use in Filterra systems.
Activation MUST be provided by the manufacturer to ensure proper site conditions are met for Activation, proper installation of
the vegetation, and use of pretreatment mulch acceptable for use in Filterra systems.The purchaser should request Activation from
Contech after the site is stabilized, but prior to turning over the site to the owner. Please allow 1-2 weeks to schedule Activation.
The purchaser must ensure that the site is acceptable for Filterra Activation.A checklist(included as page 3 of this document must be
completed and submitted to the Contech Activation Coordinator.The minimum 4 requirements for Filterra Activation are as follows:
1.The purchaser must have sourced vegetation meeting the requirements outlined in "Plant Selection for Filterra Systems"
