Drainage Management


 Stormwater Management

 

The City of Gainesville needs your help to preserve water quality in our creeks and lakes. Most people do not realize that putting trash carts and recycle bins or leaving grass clippings and leaves from yard maintenance in the street or dumping yard debris into stormwater ditches and ponds creates problems for stormwater drainage system. 

Stormwater systems are designed to hold water run-off from specific areas. Water is held to be treated over time to remove pollutants and debris. When debris left in the street makes its way into ditches or stormwater basins, it combines with other debris and can overload the system. All Storm drains lead to our Ponds, Streams, Lakes and Rivers! And when they are functioning properly, below are examples

 

 

                                                                                       

 

   

Storm Drains Are Only For Rain!

Common sources of storm water pollution include litter, trash, pet waste, paint residue, organic material (yard waste), fertilizers, pesticides, sediments, construction debris, cooking grease, illegally dumped motor oil, and other harmful fluids. Many of these pollutants come from everyday activities and can be easily reduced by using common sense and good housekeeping practices. Good housekeeping measures used to reduce storm water pollution are commonly referred to as Best Management Practices or   BMPs.

                       

The storm drain system is comprised of gutters and storm drains which are designed to prevent flooding by moving rain water away from City streets and directly into local rivers (which flow to the ocean). Storm water pollution is occurring because rainwater and urban runoff (such as irrigation) pick up pollutants as it flows across paved surfaces and then carries the pollutants into the storm drain system. The water that enters this system is not ever treated or filtered, and therefore any pollutants washed into the system flow with the water directly into the rivers and to the ocean.                                                                          

 

DRAINAGE MAINTENANCE


    OPEN WATERCOURSE SYSTEM:  include the maintenance and care of roadside ditches, swales, retention/detention ponds and watershed flood control systems.

    CLOSED WATERCOURSE SYSTEM: includes maintenance of inlets, catch basins, manholes, pipes and outfall structures which are inspected annually. Maintenance activity in this system is generated by customer concerns, inspection and   meteorological events.

 ROUTINE SCHEDULED MAINTENANCE: This type of maintenance accounts for 60% of activity. This process through inspection of system generates additional maintenance activity. Routine maintenance is mowing and cleaning, checking inlets and outfall structures. Other maintenance activities are machine cleaning and excavating (for example, hydroscopes, trackhoes, backhoes, etc.). Removing debris and sediments from systems and activities related to erosion control and repair. Scheduled maintenance occurs 4 to 5 times a year.

 

 The Drainage Crewleader is responsible for the inspections, maintenance and records for all drainage activities in his area of responsibility. The Drainage Section is divided into two areas of responsibility , east and west. The Drainage Section Crewleader schedules and supervises the maintenance operations. When pipe repair or construction is required, the task is turned over to the Construction Drainage Crewleader to perform necessary maintenance and to keep appropriate records.
