Under Ground Piping Networks

Design underground piping with easy flushing, cleaning, accessible wells, and insulation for trenches, ensuring regular inspections and straightforward maintenance. Coordinate crossings, depth, and protection with all disciplines.

Catch basins collect surface drainage at the low point of paving in underground networks, with a 12 by 12 meter layout and gravity flow; maintain 15 meters from heaters.

Investigate invert elevation within underground piping networks and how bottom line behavior and line movement relate to the system.

Explain how a diversion pit in underground piping separates oil and water during monsoon, using two wells and staged valve operation to route collected drain before stormwater.

Design vent pipes for underground networks to safely release gases, set vents at least three meters above the highest point, and integrate offline procedures, design bases, and process recommendations.

Explore cleanouts as essential for inspecting and cleaning underground piping networks. Discuss access points, tapping, flanges, blind flanges, and the need to clean headers and pits.

Understand lifting stations in underground piping networks, including pumps with a standby unit, manholes, piping, and instrumentation, as they move wastewater to the effluent treatment plant, with depth considerations.

Explore six underground networks, including cooling water systems, oily water, sea water, contaminated rainwater, and stormwater, and learn protection measures and closed blowdown techniques.

Learn the design and operation of underground cooling water networks, including supply and return lines, manholes, tapping connections, and protection for pumps and exchangers.

Explore open underground networks for oily water, contaminated rainwater, and stormwater, including inputs, responsibilities, and layout details like headers, taps, and manholes.

Understand closed blowdown and amine networks in underground piping, including underground to aboveground interfaces, drain collection from boilers and steam drums, rainwater handling, and drum elevation for safe maintenance.

Understand the purpose and inputs for composite drawings of underground facilities within a piping network. Identify and resolve clashes and constructability issues across disciplines by following minimum drawing requirements.

Explore how underground piping networks split responsibilities among civil, piping, and process teams, guided by product specifications, with planning, estimation, and 30–90 percent design milestones.
