Manhole structures battle environmental influences—fluctuating groundwater table, hydrostatic pressures, PH factors, and H2S corrosion. To combat these conditions, control I&I, and restore integrity, the engineer, owner and contractor have defined roles and responsibilities. Efficiency and effectiveness matter. Know your role. Know the issues. Learn the whys. And plan manhole and wet well rehab for the long run.
This one-hour, online-learning event promises clarity from multiple perspectives: engineering, contracting and technology experts.
