Overview

Why monitor sewage?

  • Sewage is a danger to human health and also has an ecological impact on the animals and plants living in waterways. For instance, algal blooms are encouraged by the presence of sewage. Sewage contains nutrients: releasing large amounts of nutrients into stagnant waterways raises the probability of blue green cyanobacteria blooms occurring
  • Sewage can be a major health hazard as it commonly produces potent toxins that can result in people experiencing skin rashes, eye irritations, fever, muscle pain and worse. Sewage can also be a significant hazard to animals; dog owners and farmers need to ensure their pets or livestock do not drink from waters affected by sewage
  • Sewage release into public recreational waterways is a focus of increasing public concern. In the UK, the Rivers Trust, Surfers Against Sewage and Wild Swimming are but three of the pressure groups pressing for monitoring and transparency. Sewage was discharged 400,000 times into public rivers in the UK in 2020
  • The Environment Act 2021 cracks down on water companies that excessively discharge sewage. It includes a duty enshrined in law to ensure water companies secure a progressive reduction in the adverse impacts of discharges from storm overflows. New duties also require the government to publish a plan to reduce sewage discharges from storm overflows by September 2022 and to report to Parliament on the progress towards implementing the plan

Sewage alerts straight to your phone

Most water monitors are expensive, require to be installed by engineers or operated manually, have limited data output, inflexible and with battery or mains powered. The Omnis+ sewage detection system has been designed with convenience in mind.

The Omnis+ sewage detection system is robust, always connected, self-powered, portable, easy to install, with a live data dashboard and notification alerts.

The Omnis+ sewage detection system has been designed to improve water quality around the world by providing an easy, accurate and reliable way of monitoring conditions. Data is displayed on a real-time dashboard, over multiple devices with instant notifications and alerts should water quality levels drop.

This means the Omnis+ sewage detection system’s technology can solve business challenges, as well as address issues raised via the live data received before potential loss.

The Omnis+ sewage detection system uploads readings at regular time intervals and can be configured according to your requirements. This real-time data is represented graphically as part of your custom dashboard – allowing you to quickly compare parameters and gather information across multiple sites.

Preset alerts can be triggered to keep you informed of sudden changes, extreme levels, or irregular data. Whether in the office, on site, or travelling between locations, the Omnis+ sewage detection system app and online dashboard allow you to review data when it suits you.

Built specifically for Android and iOS devices, as well as offering multi-browser support, the app will fit around your schedule and working routine.

The Omnis+ sewage detection system can be customised for your needs, you can choose other monitoring probes based on your specification to monitor all the parameters needed to ensure your water quality stays consistent and level.

The Omnis+ smart water system has been designed to be adaptable, easy to install and cost effective to get a full understanding of the technical specification find out more in the datasheets below.

Sewage monitoring with the Omnis+ sewage detection system

Any release of sewage or slurry to an aquatic environment will introduce bacteria which will then also grow rapidly and multiply. These bacteria use up oxygen in the water, causing dissolved oxygen levels to drop rapidly. When dissolved oxygen levels fall rapidly, this is extremely harmful to the aquatic environment, with visible symptoms such as fish dying en-masse also regularly in the news.

Because human sewage leads to Tryptophan activity, we can measure such spillages of human waste into aquatic environments with a Tryptophan sensor, which is part of the Omnis+ sewage detection system. A sensor for tryptophan can also help identify leakage from sewer pipes in river locations, and, together with other sensors, even differentiate whether it is due to farming or human activity.

    Specifications

    Standard Omnis+ parameters

    In addition to the specialist Chelsea Technologies sensors, the Omnis+ system also contains all the standard sensors expected in water quality monitoring systems, namely dissolved oxygen, conductivity, turbidity & pH.

    Omnis+ sewage detection system parameters

    The Omnis+ Sewage Detection System contains the tryptophan sensor of the UviLux range. The UviLux range encompasses a variety of sensors each of which can be added to your Omnis+ Sewage Detection System. For example, should you wish to monitor fuels in addition to Tryptophan, you would add an additional BTEX sensor to your Omnis+ Sewage Detection System

    The sensitivity and calibrated range of each UViLux sensor has been standardised by cross-correlating each calibration solution against a certified reference standard of quinine sulphate using a bench-top spectrofluorometer.  Fluorescence is reported in Quinine Sulphate Units (QSU), where 1 QSU is equivalent to the fluorescence intensity recorded from 1 ppb quinine sulphate at an excitation wavelength of 347.5 nm and an emission wavelength of 450 nm. Factors are provided for selected compounds to convert the fluorescence output from QSU to ppb of the compound of interest

    Omnis+ Sewage Detection System Wiper

    The Omnis+ Sewage Detection System is fitted with an automatic antifouling wiper, which removes contamination on the sensor surface preventing the adhesion of microorganisms, reducing maintenance visits.
