New Castle County and DelDOT are locating and inventorying all drainage
inlets into the stormwater drainage system. A marker is placed in
a visible location at each drainage inlet. The marker features the
water quality message “ONLY RAIN DOWN THE STORM DRAIN”.
These markers will serve as a reminder to all of us that what we
put on the land eventually ends up in our waterways. Drainage inlet
location coordinates are recorded with a GPS and used to create
a map of the drainage system including drainage inlets and the corresponding
outlets as recorded in the dry weather screening.
