The cost of 1 unit of water from Delhi Jal Board is not a fixed price but varies depending on your total monthly consumption. This is due to a tiered pricing structure that applies different volumetric charges per unit (kilolitre) based on the consumption slab, along with a fixed service charge for each slab.
Understanding a Water Unit in Delhi Jal Board
In the context of Delhi Jal Board, a "unit" of water refers to one kilolitre (KL). One kilolitre is equivalent to 1,000 litres of water.
Delhi Jal Board Water Tariff Structure
Delhi Jal Board implements a progressive tariff system, meaning the volumetric charge per kilolitre increases as your monthly consumption crosses certain thresholds. Additionally, a service charge is applied based on the consumption slab.
Here's a breakdown of the current water charges:
| Monthly Consumption (Kilolitre) | Service Charge (Rs.) | Volumetric Charge (per Kilolitre) |
|---|---|---|
| 0-10 KL | 55.00 | 2.20 |
| 10-20 KL | 110.00 | 3.30 |
| 20-30 KL | 165.00 | 16.50 |
| Over 30 KL | 220.00 | 27.50 |
How the Cost Per Unit (Kilolitre) Is Applied
- For the first 10 KL of consumption: Each kilolitre of water is charged at Rs. 2.20. In addition, a service charge of Rs. 55.00 is applied.
- For consumption between 10 KL and 20 KL: Once consumption exceeds 10 KL, any additional kilolitres within this slab (up to 20 KL) are charged at Rs. 3.30 per kilolitre. A service charge of Rs. 110.00 is applied if your total consumption falls into this slab.
- For consumption between 20 KL and 30 KL: If your consumption goes beyond 20 KL, each subsequent kilolitre up to 30 KL is charged at a higher rate of Rs. 16.50 per kilolitre. The applicable service charge for this slab is Rs. 165.00.
- For consumption over 30 KL: For any consumption exceeding 30 KL, the highest volumetric charge of Rs. 27.50 per kilolitre is applied to the units above 30 KL. The service charge for this highest slab is Rs. 220.00.
It is important to note that the service charge is applied based on the highest slab reached in your monthly consumption, and the volumetric charges are cumulative across the slabs. Therefore, the "cost of 1 unit" is not a single value but rather a rate that changes based on your overall water usage for the billing cycle.
