A novel solution to sanitary sewer overflows

feature 1 art

Significant attention has been given to the issue of combined sewer overflows (CSOs) by regulators, technical professionals, and the public, and rightly so. By design, many CSOs discharge untreated wastewater and stormwater directly to surface waters through managed control points during wet weather events.

The issue of sanitary sewer overflows (SSOs), however, has received much less attention, although SSOs may be just as common as CSOs and more important from a water quality standpoint.

WEF and WateReuse tell U.S. Senate that funding SRF boosts economy  

If the Clean Water and Drinking Water State Revolving Funds (SRFs) are reauthorized this year in U.S. Congress, it may be due in large part to the efforts of the Water Environment Federation (WEF; Alexandria, Va.) and the WateReuse Association (Alexandria, Va.).

What lurks beneath 

Beginning a sewer rehab project is a lot like going to a horror movie. You’re nervous, but excited, going in. You expect a few surprises, and there might be a monster lurking around the corner. In the case of the sewer project, the monster and the surprise might be one and the same.

This was the case for the city of Revere, Mass. During a cleaning in preparation for some rehabilitation work on an aging sanitary sewer, a 450-m (18-in.) diameter clay pipe collapsed beneath a busy road. The collapse set into motion an emergency repair project that was complicated by the location of multiple other utilities above the wastewater lines. Essentially, the city had to conduct a major water project literally on top of the emergency sewer repairs.

On the other side of the country, San Diego faced its own collection system challenges. Aging infrastructure that lacks redundancy cannot be taken out of service easily for inspection and maintenance, but failure would lead to monstrous indirect costs and ramifications. This means preventive measures, however difficult, are crucial.

The city inspected more than 90 access structures during 3 months. Inspection crews worked at night, during low-flow periods, to observe the maximum amount of surface within the structures. However, working in large-diameter, in-service pipelines required experienced crew members and significant safety planning.
