SMARTCOVER H2Scents – Reliable, Real-time Measurement of H2S Levels in Harsh Remote Environments

Smartcover-Covers for Harsh Environments


Hydrogen Sulfide (H2S) is the most commonly known and prevalent odorous gas in domestic wastewater collection and treatment systems. Bioreactions within a collection system and wastewater treatment plant processes generate H2S, causing odors. These can can be strong, persistent, and a nuisance to employees, residents, and businesses located near manholes, pump stations and wastewater treatment facilities.

Pump & Valve Specialties are the sole partner for SmartCover systems in New Zealand.

Presence of H2S can cause:

  • Sewer pipe crown corrosion leading to reduced pipe life and risk of catastrophic failure
  • Corrosion of treatment plant process equipment leading to premature failure
  • Escalation of wastewater treatment chemical costs
  • Negative impact to chemically enhanced primary treatment (CEPT) processes
  • Community odor complaints

H2Scents® is an application designed to enable reliable, real-time measurement of H2S levels over extended periods of time.
Locations where the system can be deployed include:

  • Force main discharges
  • Pump station wet wells
  • Gravity lines
  • Siphons
  • Industrial discharge points
  • Headworks/bar screens
  • Aerated grit basins
  • Primary clarifiers
  • Solids dewatering operations
  • Industrial sites

This technology can also be used in a range of industrial sites such as refineries, oil & gas production, chemical manufacturing, and food processing.
The SmartCover system is specifically designed for low maintenance installation and service without confined space entry, ensuring staff safety and reducing deployment time and costs.
Manhole covers may be pre-configured and installed with a simple swap of the cover to accelerate deployment and minimize staff time in traffic impacted areas.
In addition to gathering data from the most remote, hard-to-reach locations, readings are incorporated into the SmartCover software platform to enable done-for-you trend analysis with the ability to integrate the H2S data with level, flow or rain data.
The distinctively engineered H2Scents® sensor delivers 90 days continuous service without the need to calibrate and up to two years battery life.
Real-time alarms are issued when critical levels are triggered.
