How are Chennai Metrowater bills calculated?

Chennai Metrowater bills are calculated using a slab-based system where different rates apply to different consumption levels. The bill includes water charges (based on usage slabs), sewerage charges (60% of water charges), and water cess (₹2 per KL). Core areas and Added Areas have different tariff structures.

What are the slab rates in Chennai?

For Domestic Core areas: 0-10 KL (₹8/KL), 11-15 KL (₹15/KL), 16-25 KL (₹25/KL), 26-40 KL (₹35/KL), 41+ KL (₹45/KL). Added Areas have lower rates. Commercial properties have higher rates starting from ₹25/KL in Core areas.

How can I reduce my water bill in Chennai?

Install water-saving devices like aerators and low-flow fixtures, fix leaks promptly, use treated water for gardening, implement rainwater harvesting, and monitor your daily usage to stay within lower slabs.

What's the difference between Core and Added Areas?

Core areas are the original Chennai city limits with higher tariffs and better infrastructure. Added Areas are the expanded regions with lower tariff rates but similar slab structure. The zone affects both water charges and fixed charges.
