Tenant submetering and billing from the meter, not the floor plan
Allocating utilities by floor area charges light users for heavy ones and leaves recoverable cost on the landlord's books. Aqueduct Billing Management bills each tenant from dedicated and shared meters, shows the current cycle as it accrues, and flags usage outside each tenant's own range.

Fair recovery starts with knowing who used what.
Where tenant recovery leaks
- Area-based allocation
Tenants pay by square foot, not by use, and disputes follow.
- Shared meters
Several tenants on one meter need a split that both landlord and tenant accept.
- Late surprises
Unusual use is noticed only when the bill arrives, long after it could be explained.

Rules and results behind submetering
from this date, covered NYC tenant spaces larger than 5,000 sq ft must be sub-metered for electricity.

Map meters to tenants
Each meter is marked dedicated or shared, with each tenant's share of shared meters.
Accrue the cycle
The current cycle shows value to date, so the total is visible before month end.
Check against the tenant's range
Anomalies fire when use falls outside that tenant's own normal pattern, not on absolute size.
Issue and track
Bills generate on demand with line items per meter, and recovery is tracked by tenant and facility.
Portfolio questions the data answers
| Metric | What it tells you | Act when |
|---|---|---|
| Cost by tenant | Who drives cost | One tenant's share jumps. |
| Cost by facility | Where cost sits | A site diverges from its peers. |
| Recovered against incurred | How much is recovered | Recovery falls below target. |
| Usage against rate effect | Why a bill changed | A tenant disputes a bill. |

Common questions
A tenant on a shared meter sees only their own share. The landlord sees total consumption and every tenant's share, plus anomalies needing attention across tenants. See trust and security.
Electricity, water and gas are all supported, whether a meter serves one tenant or several. Each bill lists line items per meter with period, total and change from the last cycle, and bills can be generated on demand. See electricity meters.
No. Aqueduct produces the metered bill and line items. Invoicing and collection can stay in your accounting system, which receives the figures and line items for each tenant and cycle. See for CFOs and finance teams.
Aqueduct judges each tenant against its own history rather than a fixed size limit. A small tenant doubling its use is caught as readily as a large one. See utility bill validation.
