South Shore, Nassau County, Long Island, NY drains receive water from street gutters on most motorways, freeways, and other busy state parkways. Storm Drains in Nassau County, Long Island also receive water from local towns in areas with heavy rainfall that leads to flooding, and coastal areas of Nassau County, Long Island, NY with regular storms like Long Beach, Massapequa, and Merrick to name a few. Even gutters from houses and buildings can connect to the storm drain. Many storm drainage systems in Nassau County are gravity sewers that drain untreated storm water into rivers or streams. Due to Environmental concerns and respect for nature in general, it is unacceptable to pour hazardous substances into the drains. Storm drains often cannot manage the quantity of rain that falls in heavy rains or storms in Long Island. Inundated drains can cause basement and street flooding throughout Nassau County, NY. Many areas require detention tanks inside a property that temporarily hold runoff in heavy rains and restrict outlet flow to the public sewer. This reduces the risk of overwhelming the public sewer. Some storm drains mix stormwater (rainwater) with sewage, either intentionally in the case of combined sewers, or unintentionally.

There are two main types of stormwater drains Side Inlets & Grated Inlets. Side inlets are located adjacent to the curb and rely on the ability of the opening under the back stone or lintel to capture flow. They are usually depressed at the invert of the channel to improve capture capacity. All Storm Drains Inc. cleans and manages storm water removal for these types of drains throughout Long Island, NY on a regular basis. Many inlets have gratings or grids to prevent people, vehicles, large objects, or debris from falling into the storm drain. Grate bars are spaced so that the flow of water is not impeded, but sediment and many small objects can also fall through. However, if grate bars are too far apart, the openings may present a risk to pedestrians, bicyclists, and others in the vicinity. Storm drains in streets and parking areas must be strong enough to support the weight of vehicles and are often made of cast iron or reinforced concrete.

Some of the heavier sediment and small objects may settle in a catch basin, or sump, which lies immediately below the outlet, where water from the top of the catch basin reservoir overflows into the Long Island sewer proper. The catch basin serves much the same function as the "trap" in household wastewater plumbing in trapping objects.

In the Nassau County NY, unlike the plumbing trap, the catch basin does not necessarily prevent sewer gases such as hydrogen sulfide and methane from escaping.

The performance of catch basins at removing sediment and other pollutants depends on the design of the catch basin, and on routine maintenance to retain the storage available in the Long Island sump to capture sediment. Local Nassau County municipalities typically hire All Storm Drains Inc. to perform this task.

Catch basins in Nassau County act as the first-line pretreatment for other treatment practices, such as retention basins, by capturing large sediments and street litter from long island resident’s runoff before it enters the storm drainage pipes.

A storm drain culvert under the main road of Long Island empties into a bigger open channel. Pipes can come in many different cross-sectional shapes. Drainage systems may have many different features including waterfalls, stairways, balconies, and pits for catching rubbish, sometimes called Gross Pollutant Traps (GPTs). Pipes made of different materials can also be used, such as brick, concrete, high-density polyethylene or galvanized steel. Fiber reinforced plastic is being used more commonly for drain pipes and fittings.

Most drains in Long Island have a single large exit at their point of discharge (often covered by a grating) into a canal, river, lake, reservoir, sea or ocean. Other than Nassau County catch basins, typically there are no treatment facilities in the piping system. Small storm drains may discharge into individual dry wells. Long Island storm drains may be interconnected using slotted pipe, to make a larger dry well system. Storm drains may discharge into man-made excavations known as recharge basins or retention ponds.
