Yes, there are standards and regulations that govern the installation of water pipes and electrical power cables to ensure safety and functionality. In many countries, these standards are set by organizations such as the American National Standards Institute (ANSI) or the International Electrotechnical Commission (IEC), and they cover aspects like materials, installation practices, and safety measures. Compliance with these standards helps prevent hazards such as leaks, electrical shorts, or fires. Always refer to local building codes and guidelines for specific requirements.
Water pipes represent electric circuits as both systems involve the flow of a substance—water in pipes and electric current in wires. Just as water pressure drives the flow through pipes, voltage pushes electric current through a circuit. Valves in water pipes can be compared to resistors or switches in electrical circuits, controlling the flow of water or electricity. Additionally, blockages in pipes can represent short circuits or faults in an electrical system, disrupting the flow.

Conduit fitting is used on metal pipes that house electrical wires. These fittings are not only to connect the various pieces together, but to keep a relatively water tight seal to the wires.
The minimum diameter required for pipes or conduits used as grounding electrodes is typically specified in the National Electrical Code (NEC). For grounding electrodes, the minimum diameter is generally 1/2 inch for metal piping or conduit. However, larger diameters may be necessary depending on the specific application and local codes, so it's essential to check relevant regulations and standards.
As a rough estimate, for medium voltage cables directly buried in earth, I use 2 A / mm^2 for copper conductors, and 1.2 A/mm^2 for aluminum conductors. However, the installed capacity of a cable is mostly dependent on how much heat can be dissipated to its surroundings, and ultimately the maximum temperature of the insulation material. For this reason, it is important to know how the cable will be installed, what conductor is used (Al or Cu), the cable insulation (for both thickness and operating temperature limits), soil thermal resistance (if buried), and if there are other heat sources (cables, process pipes, incident solar radiation, etc) are nearby. There are several cable manufacturers that provide reference current ratings for nominal installations. Check Nexans, Prysmian, or Okonite (US dimensions).
The root word is duct (a tube in a building, usually for ventilation, water pipes and electrical cables, etc).

Copper (electrical wiring and hot water pipes) and aluminum (high voltage cables and soda drink cans).
The recommended conduit fill for PVC pipes in electrical installations is typically around 40-53. This means that the total area occupied by cables inside the conduit should be between 40-53 of the total cross-sectional area of the conduit.
Copper wires in electrical cables. Aluminum wires in electrical cables. Iron pipes used for plumbing. Brass fittings in plumbing. Steel screws and nails. Gold contacts on electronic devices. Silverware. Stainless steel appliances. Titanium in kitchen utensils or cookware. Nickel in faucets or doorknobs.
Polychloroethene, commonly known as PVC (polyvinyl chloride), is widely used for water pipes and electrical cable insulation due to its excellent chemical resistance, durability, and low cost. Its non-conductive properties make it ideal for insulating electrical cables, while its strength and flexibility allow it to withstand pressure and prevent leaks in plumbing applications. Additionally, PVC is lightweight and easy to install, making it a practical choice for both water and electrical systems.
Whether the pipes and wiring are chased or not. A minimum distance of 200mm is recommended. Making sure that the water pipes are always underneath the electrical wiring.
The pipes are PVC electrical conduits.
