Line 6: There are predominantly two types of stormwater pits (drains/gullies) used as inlets to collect overland runoff and transfer that water to the underlying drainage/culvert network; * Grated inlets * ~~Side~~Lintel side inlets (side entry pits / kerb inlets). Examples of both are provided below. Although there are various combinations of pits that can incorporate both features, the important thing to remember is that essentially any pit inlet can be modeled if the structure details are known and the performance can be calculated. ▼ ~~<br>~~ ~~=Pit types=~~ ''under construction'' ~~<br>~~ ~~=Pit Examples=~~ Some common pit types are shown below. Note: not all variations of side entry pits, grated pits, gully pits (pots) or any similar structure are displayed, the images are typical examples of what can be modelled as a 1D pit structure within TUFLOW. ==~~Gully~~ ~~Pits~~Grates (~~Grates~~Gully Pits) == Also known as Gully Pots, these pit types are ~~commonly found within the UK~~common and are generally a square grate on top of a circular chamber and a riser outlet. The outlet will then feed into a larger culvert that forms part of the larger urban drainage network. The grate variation and sizing can influence the rate of inflow into the pit, therefore it is important to consider this when developing the depth-discharge relationships.

The pit chamber can vary depending on overall depth, the additional of any haunched riser units and the size of the underlying drainage network that pits are typical directly connected to.
