How to Calculate Domestic and Flushing Water Tank Capacity | UGT & OHT Design Guide

Описание: How to Design Domestic & Flushing UGT and OHT Tank | NBC 2016 Step-by-Step Calculation

In this video, we explain how to design Domestic and Flushing water UGT & OHT tanks as per National Building Code of India (NBC) 2016 using a step-by-step, calculation-based approach.

This detailed engineering tutorial covers:
✔ NBC 2016 basis of design (Part 9 – Plumbing Services)
✔ Population calculation as per NBC definition
✔ Potable vs flushing water demand (LPCD concept)
✔ Daily water demand calculation (Table 19.2)
✔ Storage requirement using NBC Clause 4.8.2.2
✔ UG sump and OHT capacity split (industry practice)
✔ Peak hour demand calculation (NBC Clause 4.4)
✔ Pump flow rate calculation with safety factor
✔ Final pump selection (Duty + Standby philosophy)
✔ Separate design for domestic and flushing water systems
✔ Practical examples for residential, commercial, hospital, industrial, and school buildings

This video is extremely useful for:
🔹 MEP engineers
🔹 Plumbing design engineers
🔹 Site engineers
🔹 Civil engineers
🔹 Engineering students
🔹 Interview preparation
🔹 Authority approval & BOQ justification

📌 All calculations are strictly as per NBC 2016 — no assumptions.

👉 Pause the video and verify the calculations yourself — this is exactly how NBC expects water tank design to be done.
