DEWA water bill garden estimator

Why garden watering shows up on a Dubai DEWA bill
Villa lawns and hedges can use more water in one hot month than the kitchen and bathrooms combined. DEWA residential slab tariff rises with monthly m³, so inefficient irrigation is both a plant-health issue and a bill issue. This tool turns area × litres into an AED estimate so you can decide whether drip lines and a schedule-locked timer are worth it before summer leave.

FAQ — save water Dubai garden & DEWA bills
How can I save water in a Dubai garden?
Switch thirsty daytime sprinklers to dawn/dusk schedules, favour drip or micro-spray on beds, and use a tap timer or multi-zone controller so zones never run longer than plants need. In UAE heat, timing and targeting cut more waste than buying a bigger pump.
How does garden watering affect my DEWA water bill?
Outdoor irrigation often dominates a villa summer cubic metres. DEWA residential water is billed on slab tariffs (plus fuel surcharge and 5% VAT), so every extra m3 from lawn and hedges pushes you toward higher slabs. Estimating lawn litres to m3 shows why a DEWA water bill garden spike tracks irrigation, not just indoor use.
What DEWA tariff slabs should I use for a rough garden estimate?
Public residential slabs (indicative): about AED 7.70/m3 for the first 27 m3, AED 8.80/m3 from 27-54 m3, and AED 10.12/m3 above 54 m3, plus a fuel surcharge (often about AED 1.10/m3) and 5% VAT. Always confirm on dewa.gov.ae — fuel surcharges move.
How much can drip irrigation and a water timer save on my DEWA bill?
As a planning rule of thumb, drip can cut roughly 35% versus wasteful spray, and a timer that stops over-runs can cut another 20% of what remains — about half the irrigation volume combined. Your real save water Dubai garden result depends on area, schedule, and soil.
Is this an official DEWA calculator?
No. watertimer.ae provides an educational estimate so villa owners can compare irrigation methods in AED. It is not affiliated with DEWA. Use your bill and the official slab tariff page for exact charges.
