Water Recycling Dashboard
See a building's water-recycling impact at a glance. Enter fresh water supply, sewage generated and treated water reused (in KLD) — get the reuse percentage plus the money, water and CO₂ you save every year.
Reusing treated water cuts net fresh-water demand
Your water balance
Fresh water bought / drawn per day.
Wastewater sent to the STP per day.
Recycled water actually put back to use.
Tariff for fresh water avoided by reuse.
Embodied CO₂ per KL of fresh water.
Reuse is capped at the sewage you actually generate — you cannot recycle more water than you treat.
Where your water goes
Sewage split into reuse vs discharge, and how reuse shrinks your net fresh-water demand.
Sewage: reused vs discharged
Fresh supply vs net demand after reuse
How this is calculated
- Reuse = min(treated water reused, sewage) = 130 KLD, capped at the 160 KLD of sewage you treat.
- Reuse % = reuse ÷ sewage = 81%; the remaining 30 KLD is discharged.
- Annual water reused = reuse × 365 = 47,450 KL.
- Money saved = annual reuse × Rs 60/KL = Rs 28,47,000/year.
- CO₂ saved = annual reuse × 0.7 kg/KL ÷ 1000 = 33.2 t/year.
- Net fresh demand = max(0, supply − reuse) = 70 KLD.
Indicative figures for concept planning. Actual savings depend on the reuse application, tariff slabs and treated-water quality — confirm with a qualified consultant before design.
