Sanitary and combined sewer overflows – a fast, effective solution

Protect property and your reputation

Reducing the occurrence and volume of sanitary sewer (SSOs) and combined sewer overflows (CSOs) contributes to ecologically, socially, and economically sound wastewater management for communities while protecting private and commercial property and the reputation of the water utility.

Networks with capacity issues, maintenance or structural problems such as blockages and collapses that restrict capacity, and unpredictable wet weather events, are some of the reasons why SSOs and CSOs occur.

The clock Is ticking

In the unfortunate event of an SSO or CSO incident, water operators require an emergency response solution to minimize the impact of these unforeseen events. This means mobilizing field crews in response to the incident and recording details of the spill including identifying the cause, reason, and impact of the failure.

The utility needs to determine the location, extent, and volume of the spill, and further mobilize field crews to repair and clean up the problem. Once the incident has been reported, the clock is ticking to respond quickly and efficiently, work productively and safely to get the work done, and report the findings to stakeholders such as regulators.

Estimating the spill volume and extent

Tools to help

The InfoAsset solution incorporating InfoAsset Manager and InfoAsset Mobile provides a utility with a set of tools to record the SSO or CSO incident; and ensure that up-to-date and accurate data and information is provided directly in the hands of field crews. The field crews are assigned the work via InfoAsset Manager and can use InfoAsset Mobile SSO/CSO reporting templates to complete the job in the field – no need to return to an office to do any digitizing or keying of reports. Sketches, photographs and videos associated with all aspects and stages of the work can be captured and stored centrally in InfoAsset Manager.

InfoAsset Mobile can support simple and complex workflows incorporating all aspects of the work that is required to successfully close out the incident and report to stakeholders. Work approval and requests for equipment and resources can be communicated from the field to the office. Reactive work orders can be generated in the field during or after the completion of a task, so that, after the inspection has been completed, the appropriate work order can be raised to fix the problem and schedule remediation.

Tracking crew locations

Working connected to, or disconnected from, the office

Crews using InfoAsset Mobile can work either connected or disconnected from the office if they’re in a remote area without mobile data availability.

The information, data, and media related to all aspects of the spill can be uploaded to the office from the field via mobile data communications, or when the field crews can connect to their organization’s network. This ensures that office-based colleagues can efficiently monitor the progress of the work, accessing up-to-date and relevant information as it is collected, and enabling them to provide advice to the field crews as they discover and record more details related to the spill.

Incident Reporting Form

Key performance indicators

This also enables managers to capture key performance metrics related to:

• The time it took to respond to the initial reporting of the incident
• The time it took to mobilize the crews to begin work
• How much time and resources were consumed on each task

… as well as reporting on the problems faced and learning from the experience in order, to improve the workflows in the future.

Staff in the water utility using InfoAsset Manager can quickly and efficiently query and report on any aspect of the data and information related to the incident, the work carried out, crews, equipment, material, and resources, as well as the asset that failed, answering questions related to response and completion times, cost of labor, equipment, material, and resources. Recent incidents can be analyzed in the context of historical records, providing insights into the relative performance of the network from one year to the next.

This helps the utility to properly manage, operate, and maintain its wastewater collection system to minimize sanitary and combined sewer overflows and mitigate their impact if any occur.
