Waste and street services

Waste services, collected on evidence.

Collection crews drive fixed rounds whether bins are full or empty. Fill sensors in bins and banks, gas and weather at transfer stations and depots report to one record that plans routes, keeps sites safe and accounts for waste.

  1. Cities · Waste and street services

    Rounds that ignore the bins

    A collection truck drives the same round every week, emptying half-empty bins while others overflow two streets away. Transfer stations store waste that can heat, smoke and smell. Knowing how full each bin is, and what is happening at each site, lets crews work where they are needed.

  2. What is measured

    Fill, gas, heat and weather

    Fill sensors inside street bins, recycling banks and underground containers measure how full they are. Gas detectors and heat sensors watch transfer station halls and bays, weather stations record wind for odour complaints, and every completed collection is recorded. Every reading names its container or site.

  3. The base node

    Routes from forecasts

    The city node learns how fast each bin fills and forecasts when it will be full, then builds the next day’s routes. The transfer station node raises gas and heat alarms at once. Every value is signed, so routes and alarms can be checked later.

  4. Radio and links

    LoRaWAN through metal lids

    Bin sensors in metal and underground containers reach roof gateways over LoRaWAN, for years on a battery. Gateways, transfer stations and vehicles report to the depot over cellular, and vehicles upload their collection records over the depot’s wireless. Each gateway is supervised.

  5. How it works

    From a full bin to tomorrow’s route

    A fill sensor in a recycling bank reports it nearly full. The city node forecasts it will overflow tomorrow and adds it to the next route. The crew empties it, the collection is recorded, and the overflow complaint that would have come never arrives.

  6. From order to operation · Order

    Scope the rounds and the sites

    The scope reads the collection rounds, bin and bank inventory, transfer stations and the waste records the city must keep. Nexus Observatory Inc. returns the sensor plan, the radio design, the integration with routing and waste systems and a price per sensor and per service.

  7. From order to operation · Survey

    Ride the rounds

    Crews ride rounds with the drivers to see which bins overflow and which are always empty, survey transfer stations for gas and heat points with the site manager, and check gateway coverage from roofs across each district. Their knowledge shapes the sensor plan.

  8. From order to operation · Permits

    Containers, roofs and sites

    Sensors in containers belong to the city; gateways on roofs need the owners’ consent. Transfer station points follow the site’s permit and safety rules, and every consent is kept with the record. Drivers and site staff are briefed on what the sensors do, and every consent and briefing is kept with the record.

  9. From order to operation · Build

    Build for bins

    Fill sensors, gateways, gas detectors, the industrial gateway and nodes are built, tested and enrolled with their identities. Each fill sensor is configured for its container type, and every one is labelled with the container it serves. Spares are kept at the depot.

  10. From order to operation · Install

    Install on the round

    Crews fit fill sensors inside lids and containers as rounds empty them, mount gateways on roofs, and install gas, heat and weather points at transfer stations. Every sensor is located and photographed for the record. Crews log each sensor as they fit it, so nothing is missed.

  11. From order to operation · Commission

    Check fill against the eye

    Each sensor proves its identity. Fill readings are checked against what crews see at collection, gas detectors with reference gas, and alarms are tested to the transfer station manager. Routes are generated in parallel with the old rounds first. Results are kept with each record.

  12. From order to operation · Operate

    Collect what is full

    Planners build each day’s routes from fill forecasts, crews empty what is full and skip what is not, and overflow complaints fall. Transfer stations see gas and heat with alarms, and the waste record follows from completed collections. Every route is kept on the record.

  13. From order to operation · Maintain

    Swap and check on the round

    Sensors are checked when crews notice a mismatch, batteries changed on plan, damaged sensors swapped on the next round, and gas detectors calibrated on schedule. Every change is recorded against the container or site. Spares ride on the trucks, so a failed sensor is replaced on the spot.

01The place and its hazards

Where it runs, and what can go wrong.

Operating contextCities collect household and street waste, empty recycling banks and run transfer stations and depots. Fixed rounds waste fuel and time, overflowing bins draw complaints and pests, transfer stations handle gases and fire risk, and waste rules require records of what is collected and where it goes.

Hazards

  • Overflowing bins and fly-tipping
  • Wasted rounds to empty bins
  • Fires and gas at transfer stations
  • Odour complaints from neighbours
  • Incomplete waste records

02What must be measured

What, where, how often, and under which rules.

Each measurement names where it is taken, how often, and the public standard or regulation behind it. Numbers in the sources column open the cited source below.

05From order to operation

Every step, from the first call to a running site.

The same crew and the same record carry the work from scope to maintenance.

  1. 01 Order

    Scope the rounds and the sites

    The scope reads the collection rounds, bin and bank inventory, transfer stations and the waste records the city must keep. Nexus Observatory Inc. returns the sensor plan, the radio design, the integration with routing and waste systems and a price per sensor and per service. 1

  2. 02 Survey

    Ride the rounds

    Crews ride rounds with the drivers to see which bins overflow and which are always empty, survey transfer stations for gas and heat points with the site manager, and check gateway coverage from roofs across each district. Their knowledge shapes the sensor plan.

  3. 03 Permits

    Containers, roofs and sites

    Sensors in containers belong to the city; gateways on roofs need the owners’ consent. Transfer station points follow the site’s permit and safety rules, and every consent is kept with the record. Drivers and site staff are briefed on what the sensors do, and every consent and briefing is kept with the record.

  4. 04 Build

    Build for bins

    Fill sensors, gateways, gas detectors, the industrial gateway and nodes are built, tested and enrolled with their identities. Each fill sensor is configured for its container type, and every one is labelled with the container it serves. Spares are kept at the depot.

  5. 05 Install

    Install on the round

    Crews fit fill sensors inside lids and containers as rounds empty them, mount gateways on roofs, and install gas, heat and weather points at transfer stations. Every sensor is located and photographed for the record. Crews log each sensor as they fit it, so nothing is missed.

  6. 06 Commission

    Check fill against the eye

    Each sensor proves its identity. Fill readings are checked against what crews see at collection, gas detectors with reference gas, and alarms are tested to the transfer station manager. Routes are generated in parallel with the old rounds first. Results are kept with each record.

  7. 07 Operate

    Collect what is full

    Planners build each day’s routes from fill forecasts, crews empty what is full and skip what is not, and overflow complaints fall. Transfer stations see gas and heat with alarms, and the waste record follows from completed collections. Every route is kept on the record. 1

  8. 08 Maintain

    Swap and check on the round

    Sensors are checked when crews notice a mismatch, batteries changed on plan, damaged sensors swapped on the next round, and gas detectors calibrated on schedule. Every change is recorded against the container or site. Spares ride on the trucks, so a failed sensor is replaced on the spot.

07Questions buyers ask

Before you scope it.

Do crews still empty every bin?

They empty bins that are full or forecast to be; others wait for a later round.

What about bins with no sensor?

They stay on fixed rounds until sensors are added.

Do sensors survive the truck?

They sit inside lids and containers built for collection.

Can it help with fires?

Transfer station heat and gas alarms raise early warnings.
