Trench Section
A trench is a type of excavation or depression in the ground that is generally deeper than it is wide (as opposed to a wider gully, or ditch), and narrow compared to its length (as opposed to a simple hole).[1]

In geology, trenches are created as a result of erosion by rivers or by geological movement of tectonic plates. In the civil engineering field, trenches are often created to install underground infrastructure or utilities (such as gas mains, water mains or telephone lines), 
or later to access these installations. Trenches have also often been dug for military defensive purposes. In archaeology, the "trench method" is used for searching and excavating ancient ruins or to dig into strata of sedimented material.

Trunch Block
This detail focuses on a standard trench foundation, where a cavity wall meets the floor (in this case a suspended beam-and-block floor, although this could easily be a ground-bearing slab or otherwise). The depth and width of the actual poured concrete foundation has been left off, as this varies greatly depending on the soil conditions. An AutoCAD drawing of this detail (in 2004 format) can be downloaded at the end of the article.

Scour Valve
For the purpose of releasing air in water mains, a fire hydrant or an air valve shall be installed at the highest point(s) or where required by the Water Supply Operations Manager. They shall be installed so that groundwater cannot enter the main at negative pressure and shall be in a permanent valve box. Details of an air valve are given on Drawing WS 13.

The permanent valve box for air release valves must be capable of enabling sufficient air to enter or escape from the enclosure without inhibiting the airflow performance of the air valve. The selection of the air valve shall be based on its airflow capacity being capable of protecting the pipeline and not be based on the size of the nominal bore of the air release valve to pipeline connection.
Scour valves shall be installed at low points or to facilitate draining of a water main where required by the Water Supply Operations 
Manager. Details of a scour valve are given on Drawing WS 14.
In areas where the scouring of mains is needed as a frequent operation, a connection to the stormwater curb outlets, open channels or catch it shall be provided. The connection of a scour valve to stormwater pipes or manholes is not permitted.

Crossings should be located away from conflict points at uncontrolled junctions.
This will give drivers an adequate opportunity to appreciate the existence of a crossing and
to brake safely. The â€˜safeâ€™ distance will depend on the geometry of the junction and type of
side road. However, a minimum distance of 20 metres is suggested for a signalled-controlled
crossing and an absolute minimum of 5 metres for a Zebra crossing. It is suggested that the
distance be measured from the position of a driver waiting at the give-way line of the side
road. Where it is impossible to obtain a â€˜safeâ€™ distance, consider banning turning movements
towards the crossing or make the side road one way away from the junction.

RCC Pier AutoCAD drawing
Prefabricated pier elements have been used by many state agencies. This is due to the difficulty of forming and pouring concrete high above the ground and the fact that substructures offer opportunities for repetition. There can also be significant savings by reducing construction time for substructure work over bodies of water or near hazards such as power lines.

Credle  Drawing
A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. 
Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the 
center of the pipe; passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns 
the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, so a pressure drop 
is always induced in the flow, regardless of valve position.

AIR VALVE CHAMBER
The air valve chamber is a sectionalized structure designed and developed to provide the industry with a high quality, accurate and 
long lasting method of erecting chambers. Incorporating specially designed step irons, the chambers are easy to install, can be 
made watertight and can be erected in hours rather than days.
