Sanitary & Storm Sewer Management

Smoke Testing

A proven and cost-effective method to detect leaks, cross-connections, and sources of inflow and infiltration. GHA performs smoke testing to assess large portions of a sewer system quickly, delivering clear data to help prioritize repairs and support capital planning.

Manhole Scanning & Condition Assessment

Using Manhole Assessment Certification Program Level 2 inspections and digital scanning tools, our team evaluates manhole structures to document conditions, identify defects, and provide detailed reports that support maintenance programs and GIS integration.

Lift & Pump Station Monitoring

PWO personnel provide ongoing oversight and operational support for lift and pump stations, including inspections, pump performance tracking, and coordination of maintenance activities to prevent failures and improve system reliability.

SCADA Oversight & Maintenance

We assist with the monitoring and maintenance of Supervisory Control and Data Acquisition (SCADA) systems, ensuring accurate data collection, alarm response, and operational continuity for both sanitary and stormwater networks.

Pump Station Oversight

Our team monitors and adjusts pump stations, chemical feed systems, and water treatment equipment to sustain system efficiency and maintain optimal service reliability.
