of removing the first two or three inches of discolored sand and the replacing this with new sand. At

Spillway structures and pipes including the filter drain must be inspected regularly (at least once a

OPERATIONS AND MAINTENANCE MANUAL
WATERSHED PROTECTION SAND FILTER DEVICE
OPERATION OF SAND FILTER
Sand filters satisfy the State's minimum requirements of 85% removal of Total Suspended -Solids.
The sand filter design is comprised of two basic components: the sediment chamber and :the sand
chamber. Both are important parts of the design, and neither can be omitted. The purpose of the
sediment chamber is to reduce the amount of sediment that reaches the sand chamber and to
help ensure that stormwater reaches the sand chamber as sheet flow. The purpose of the sand
chamber is to trap the finer sediment along with pollutants attached to the sediment, and to provide
a media for microbial removal of bacteria.
Sand filters work by receiving the first flush of runoff and settling out the heavier sediment in the
sediment chamber. Water then flows to the sand bed in sheet flow where pollutants are either
trapped or strained out. Sand filters are to be used only for drainage areas that have been
stabilized. Sediment from construction activity can quickly clog the sand filter, thereby reducing the
required size of the filter. Drainage areas directed to each sand filter should be kept below 5 acres
in size. Larger drainage areas area less likely to be entirely impervious, and it is more difficult to
distribute the flow of runoff across the sand bed.
Sand filter drain pipes should always be operable so that the water can be drawn down in the event
of severe rain or for repairs or maintenance.
MAINTENANCE OF SAND FILTER
The installation of a sand filter can required substantial routine and non —routine maintenance.
Debris and sediment can effectively plug a sand filter and prevent it from completing its intended
function. Weekly policing of teh filter chambers adn the drainage area contributing to the basin must
be done to prevent premature clogging. Careful attention must be paid to eliminating or preventing
sources of sediment (i.e. unstable bare earth areas, sanding parking areas during winter, etc.)
Maintenance operations must be performed when storms of approximately one inch are not passing
through the filter within 24 hours. The filter material surface must be inspected regularly to ensure
that the material has not become clogged with debris (or pollutants) and has not been compacted or
become "crusted over" so as to prevent the free flow of water. Maintenance for sand filters consists
of removing the first two or three 'inches of discolored sand and the replacing this with new sand. At

Filter basin repairs and maintenance will require a professional engineer to prepare a plan or detail
