Plumbing 104: Water Supply Systems Plumbing Design (A to Z)

Design a water supply system to industry standards using step-by-step guides, size and design the piping network, and interpret plumbing engineering drawings to understand key components and terminology.

Explore the areas of application for water supply plumbing systems, focusing on residential and commercial projects and applying the design methodologies within apartments, houses, offices, malls, theaters, and hospitals.

Explore key plumbing standards like IPC, UPC, SPC, and ASP, and learn how to apply design steps and methodologies to deliver compliant, reliable water supply system designs.

Learn how plumbing divides into drainage and water supply, with subcategories like soil drainage, greywater, and rainwater, and design a water supply system including cold and hot water supply.

Explore the water supply piping network and compare uPVC, HDPE, PPR, and PEX pipes, including where to use each, installation methods, and leak-avoidance considerations.

Copper pipes provide heat conduction for hot water lines and boilers, with higher cost and required soldering; steel and stainless steel enable durable external mains for high pressure.

Master piping network design for PPR systems by selecting fittings, including elbows, tees, 45-degree elbows, reducers, crosses, caps, unions, and clips, to route water from source to fixtures.

Explore booster and transfer pumps, pump sets with duty and standby, and control panels and drives to boost and lift water in supply systems.

Design a water supply system with a water meter to measure consumption in gallons per minute or hour, feeding each apartment from a dedicated water meter room.

Explore cold water supply from the municipal main line and hot water options—rooftop solar, basement boiler, or indoors 50l/80l heaters. Relate these to piping, tanks, and pumps.

Identify main water filtration components, including cartridge, sand, and UV filters, and distinguish internal versus external placements in residential and building systems. Mention lab tests and standards guidance.

Explore how valves regulate flow in water supply systems, detailing globe, butterfly, gate, and non-return valves for modulation, isolation, and one-way flow in main lines and fixtures.

Learn how a pressure reducing valve (PRV) lowers main-line pressure to safe levels for building connections, preventing damage from pressures above 80 psi and enabling ready-made component installation.

Provide constructive feedback to refine the current course and ensure an optimal educational journey, as the course maintains premium caliber, highest quality standards, and transitions to upcoming lectures.

learn to read engineering drawings for plumbing design by interpreting legends, symbols, and drainage layouts across floor plans, including grey water, soil stacks, vent stacks, and kitchen waste connections.

Learn to read engineering drawings and interpret riser diagrams for water supply across multi-story buildings. Visualize rooftop tanks, pumps, meters, and vertical piping to plan replicable, well-coordinated layouts.

Assess total cold and hot water demand, then size pipes, tanks, heaters, and pumps using a practical, step-by-step design sequence for any building project.

Learn essential design terminology for water supply systems, including water supply fixture units (Sfas) and hot and cold demands. Use standard tables to size branches and fixtures.

Sizes branch lines, calculates fixture units, determines main line size and flow, analyzes friction losses and available pressure, and sizes pumps, heaters, and tanks for a tailored water supply design.

Demonstrates a step-by-step design of a school water supply system from tanks to fixtures, using fixture units and sizing tables to select pipe sizes and flow velocities.

Learn to calculate pressure losses in cold and hot water supply networks from the source to the furthest fixture, using major and minor losses, pipe sizing, and equivalent lengths.

Calculate major and minor losses across cold and hot water networks from a to g, detailing segments a–b to f–g, and determine total pressure drop to assess pumping needs.

Calculate pressure losses in cold and hot water networks to determine booster pump needs, convert between psi and bars, and size the main line flow for safe, gravity-assisted operation.

Explore a step-by-step practical guide to water supply system design, calculating pressure losses, evaluating pump needs, and selecting components like prv, meters, tanks, and filters.

Learn to size centralized water heater capacity using fixture counts, gallons per hour, demand factor, and storage needs, with a school example and UPC tables guiding the design.

Size a school water tank by per-person usage and occupant count to estimate daily demand, then select a GRP or polygon tank with a three-day storage safety margin.
