The challenge

Water measured late is lost twice

Once in the network, once in the bill.

One month, one reading0 days unseen
Day 1 · likely leak begins Day 30 · the only reading
01

Manual reading

One reading a month, typing errors, meters nobody can reach.

02

Hidden leaks

Found weeks later, when the damage is done.

03

Non-revenue water

Without comparing what enters with what is billed, nobody knows where it goes.

What is Hydrix

From the meter to the decision, daily

An open LoRaWAN chain. Every link can be swapped.

01

Meter

SPD ultrasonic with built-in LoRaWAN, or ML-107G module on mechanical meters

Another brand's compatible LoRaWAN meter, once its decoder is added

02

Gateway

Long-range coverage, sized by a coverage study · each reading is heard by 2–3 gateways

Another brand's LoRaWAN gateway, same coverage study

03

Network server

Receives, authenticates and de-duplicates every reading · US915

Billed water is revenue. The loss is what nobody bills.

Alerts with follow-up

Closed only when someone solves it

Every alert has an owner, evidence and a closure.

    Business models

    Three ways to get Hydrix

    From a monthly fee to a fully bundled service.

    Recommended

    Subscription

    Monthly fee per meter. SPD hosts, updates and supports.

    Grows with you

    Perpetual license

    One payment, on the utility's server, plus annual plan.

    Full control

    Where your hardware matters most

    Reading as a service

    Meters, gateways, installation and Hydrix in one fee over 60 months.

    No upfront investment

    Hydrix subscription

    More meters, a lower rate for all

    All meters pay the rate of the band your total falls in.

    Over 10,000
    Monthly$14,400.00
    Annual$172,800.00
    Rate per meter$0.80/ month
    1. Up to 1,000$2.50
    2. 1,001 – 3,000$1.80
    3. 3,001 – 10,000$1.10
    4. Over 10,000$0.80

    Every meter, the same rate

    Includes: Hydrix, hosting, backups, updates and support.

    Prices in USD per meter per month, excluding VAT. Minimum billing 500 meters. Annual contract, adjusted yearly for inflation.
    Floor: you never pay less than the top of the previous band ($2,500 / $5,400 / $11,000), so adding meters never lowers the bill.
