About Downtown-Old Town Sewer Repair Program
Information
The Downtown-Old Town Sewer Repair Program is a multi-year and multi-million-dollar investment to assess the condition and capacity of the aging public sewer system serving Portland's Downtown and Old Town neighborhoods and to construct the necessary repairs and upgrades.
About the Secondary Treatment Expansion Program
Information
STEP is the largest improvement project at the treatment plant since the 1970s. The improvements will increase the plant's resiliency, protect water quality, and provide healthier work environments for essential workers.
Cured-in-Place-Pipe Lining (CIPP)
Information
Cured-in-Place-Pipe Lining (CIPP) is a trenchless method of sewer construction. It requires little or no digging and significantly less time to complete than other sewer repair methods. It is suitable for repairing both short and long runs of pipes that do not need to be upsized.
Emergency Inverness Force Main Repair
Information
Environmental Services has completed repairing a 20-inch diameter pressurized pipe at the base of the Columbia Slough bike/pedestrian bridge north of the Columbia Blvd Wastewater Treatment Plant. Repair of the aging pipe protects public health and the environment.

Grouting
Information
Grouting is a trenchless construction method used to stop leaks in sewer pipes and maintenance access holes without having to do more complex and costly structural repairs. It is effective in repairing leaky pipes and joints, sealing small cracks, and filling voids in the soil outside of pipes.
Horizontal Directional Drilling (HDD)
Information
Horizontal Directional Drilling (HDD) is a trenchless method of sewer construction. It is suitable for soft to hard clays, wet soils, and environmentally sensitive areas. This method avoids having to dig large pits to install jacking and boring machines.
Jack and Bore
Information
Jack and Bore is a trenchless method of sewer construction. It is suitable for installing short pipe runs in stable and dry soils without large boulders.
Microtunneling
Information
Microtunneling is a trenchless method of sewer construction. It is effective in soft, unstable, and wet soils and can crush large boulders. The tunneling process is remotely controlled and can be used to install larger diameter pipes and longer pipe runs than the Jack and Bore method.
Open Trench Excavation
Information
Open Trench Excavation is the traditional method of sewer construction and the most common method for replacing a sewer pipe, especially if the original pipe needs to be upsized.
Pilot Tube Microtunneling
Information
Pilot Tube Microtunneling is a trenchless method of sewer construction. It is effective where pinpoint accuracy is needed for the line and the grade of the sewer pipe installation—where several underground utility lines exist in close proximity, for example.
Pipe Bursting
Information
Pipe Bursting is a trenchless method of sewer construction. It is an alternative to the Open Trench Excavation method that allows for replacing or upsizing an existing pipe without the need for a traditional construction trench.
Pipe Reaming
Information
Pipe Reaming is a trenchless method of sewer construction. It allows for replacing or upsizing an existing pipe without the need for an excavated open trench. It is used to remove underground sewer pipes while simultaneously installing new pipes.
Pre-Construction Activities
Information
During the project design process, crews will be in the neighborhood conducting various investigations to collect information that will help them determine what pipes need to be repaired and what construction methods should be used.
Sanitary Sewer and Stormwater Rates and Charges
Information
Environmental Services delivers sanitary sewer and stormwater services to Portland residents and businesses. Rates and charges are based on the cost of providing services.
Environmental Services repairs more than 50,000 feet of pipe each year using a variety of sewer construction methods. Each method creates different levels of noise and disruption to neighborhood activities. Learn more about sewer construction methods.

Sliplining
Information
Sliplining is a trenchless method of sewer construction. It requires less digging and often less time to complete than other sewer repair methods. It is suitable for repairing both short and long runs of pipes that do not need to be upsized.
Spiral Wound Pipe Lining
Information
Spiral Wound Pipe Lining is a trenchless method of sewer construction. It requires little or no digging and can be installed when sewage and stormwater are flowing through the pipe. It is suitable for repairing both short and long runs of pipes that allow for lower overall capacity.
