Smoke testing is a common diagnostic tool used to locate sources of inflow and infiltration in a sewer system. Smoke testing has been around for many years, but little information is available to help municipalities understand what to expect during such testing. How do I plan for such a project? What can I expect to find? How do I handle public relations? This paper presents a case study that evaluates and expands upon these issues based on facts, figures, and lessons learned from 1,000,000+ ft of smoke testing recently completed in Huntsville, Alabama. The results provide guidance for sewer managers and engineers to better understand what to expect during smoke testing and suggestions to better educate the public and other City departments.

Picking the right Sewer Camera
Sewer camera models are pretty straightforward, in most cases. But, there are many options if you want a sewer camera or commonly called snake camera. This type comes many varieties: Pipe Inspection camera with viewing capabilities only, sewer camera with locator, rigid sewer camera, intrinsically safe camera, VIS 350 camera, Wohler VIS 350 camera with detachable heads, push camera with 6mm diameter camera, drain camera, quality sewer camera, cheap sewer camera, color sewer camera, plumbing inspection camera,...
Identification of potential sewer mining locations: a Monte-Carlo based approach
Rapid urbanization affecting demand patterns, coupled with potential water shortages due to supply side impacts of climatic changes, has led to the emergence of new technologies for water and wastewater reuse. Sewer mining (SM) is a novel decentralized option that could potentially provide non-potable water for urban uses, including for example the irrigation of urban green spaces, providing a mid-scale solution to effective wastewater reuse. SM is based on extracting wastewater from local sewers and treatment at...
Pumping Wastewater into Existing Pressure Sewer
Romtec Utilities designs, manufactures, and supplies pumping systems for many different applications. Our systems include all structural, all mechanical, all electrical, and all communications systems in a single purchase. Many of our systems are designed and supplied to handle sewage and wastewater flows in a lift station design. In many scenarios, these lift stations are for new construction like residential and commercial developments. Sewer infrastructure is typically available, and with some projects,...
Sewer Lift Station - Case Study
Client: The City of Phoenix Facility: A sewer Lift Station (LS) located directly adjacent to a residence. (LS 48) Problem: The impact of facility safety and maintenance were main concerns. Decision: The client chose to replace a chemical scrubber with a BOHN BIOFILTER system. Outcome: The facility now exceeds the Maricopa County air quality requirement of 0.030 ppb H2S at the property boundary.
Numerical modelling of air-water flows in sewer drops
The presence of dissolved oxygen (DO) in water flows is an important factor to ensure the aerobic conditions recognised as beneficial to preventing the occurrence of detrimental effects. The incorporation of DO in wastewater flowing in sewer systems is a process widely investigated in order to quantify the effect of continuous reaeration through the air-liquid interface or air entrained due to the presence of singularities such as drops or junctions. The location of sewer drops to enhance air entrainment and...
