Where Are Sand Traps Installed and Why?

When it comes to keeping drains and wastewater pipes unencumbered and free from debris, the installation of traps becomes necessary. Traps are fittings which are installed at the points of exit of the wastewater, allowing for only the water to flow out and leave the debris out of the pipes. Sand traps, as their name suggests, are essentially used to keep out the sand, grit and other particle matter which may flow into the pipes from the inflow of the wastewater. Let us look at some of the places where the sand traps may be installed and the functions they serve there:

1.One of the most common places for the installation of sand traps are pavements and roads. Sand traps are often installed as part of the public drainage system at the subsurface level, helping in water and flood management. The traps serve to keep out the particle matter from flowing into the main drainage pipes of the city, preventing blockages in the pipes over time and keeping the waste particle matter from flowing into the oceans and water bodies. 

2.In houses and buildings where rainwater drainage systems are installed on the roof, sand traps may also be installed at the entry point of the individual downpipes. This is done in order to prevent any debris in the form of leaves, plant matter, twigs or any other large particle waste from getting into the downpipes and keeps the system functioning optimally. 

3.Sand traps also serve as the first level of filtration in many a water management system. The sand trap serves to remove the bigger and heavier particles through the action of gravity, allowing for the water to be taken to the next tank for the second level of filtration. 

4.In some places, sand traps may also be installed near oil and petrol stations along with grease traps. The sand trap here serves to keep the oil and the grease generated from the station from getting into the pipes and keeps them free from scaling and blockages without impeding their functionality.
