Water Utilities Projects

The Water Utilities Department is dedicated to ensure a safe, reliable and efficient water and wastewater distribution system for all its water and wastewater customers. The City continually strives to maintain and improve public infrastructure to help safeguard the vitality of our economy and quality of life.


The following infrastructure projects are underway:


Downtown Water and Sewer Pipeline Replacement

Loma Alta Creek Sewer Replacement Project

Morro Hills No. 1 and No. 2 Reservoirs Repair Project

Sewer Pipe Cleaning and Condition Assessment


Beginning Fall 2016, the City of Oceanside Water Utilities Department will begin the Downtown Oceanside Water and Sewer Replacement Project.


This project will replace important water and sewer lines, improve drinking water deliveries and enhance wastewater flow to ensure a safe, reliable and efficient water and wastewater distribution system.


Additional Project Benefits:

  • Waterlines will be more reliable and have a useful life of more than 100 years

  • Project will facilitate better routine cleaning and maintenance of sewer lines

  • Increased water flow and improved firefighting capabilities

Construction Schedule and Hours

Fall 2016 – Fall 2017

Monday – Friday, 7:00 am to 4:00 pm.   No equipment to operate prior to 8:00 am.

No work will occur on Thursdays near the Farmer’s Market area.


Project Details

The project is scheduled to be complete in Fall 2017 and includes replacing water meters, hydrants, customer water service connections, 1.8 miles of water lines, and 2.1 miles of sewer lines. To minimize impacts to the surrounding properties, temporary pipelines and pumps will be in place to allow for normal water delivery and sewer collection throughout the course of the construction.


Potential Impacts


Alley and Lane Closures - Pipeline replacement will be primarily located in residential alleys. During construction hours, alleys or a road lane will be temporarily closed and detours provided. The closure will take up to two weeks. If driveway/garage/loading area is blocked and access is necessary, access will be provided by the contractor upon request.  Please expect delays and drive cautiously around construction.


No Parking - There will be times when temporary “no parking zones” will be needed during construction hours. Temporary “no parking” signs will be posted 48 hours before parking restrictions begin.


Trash Bins - Trash bins may need to be temporarily relocated. Notifications will be distributed with more information if this applies to your home/business.


Temporary Water Shut-Off - At the end of each water replacement section, there will be a temporary eight-hour water shut off to connect the new pipeline connections to the existing mainlines. Residents and businesses will be informed of the shut off at least 48 hours in advance.  Shutdowns will occur during regular working hours and last no longer than 8 hours.


Thank you for your patience during this important infrastructure project.

Project Map



Loma Alta Creek Sewer Replacement Project

An emergency sewer pipeline replacement project is underway north of Loma Alta Creek between Rancho del Oro Road and El Camino Real and on Oceanside Blvd. Construction began in May 2016 and is projected to end in February 2017.


The project is considered an emergency project due to corrosion and structural degradation conditions of the existing sewer pipeline running through Loma Alta Creek. The sewer line replacement project was prioritized to be built away from the creek to avoid a potential sewer spill. Once the new sewer line is complete, the old pipe will be abandoned. 


The new 18-inch sewer pipeline is being constructed 20 to 25 feet deep. At that depth, the contractor has encountered a significant amount of groundwater, thus extending the original duration of the construction. Due to project conditions and to reduce traffic control impacts to the intersection of Rancho Del Oro and Oceanside Blvd., the contractor will drill portions of the pipeline verses the traditional open trench method.


The project requires 24-hour traffic control in construction zones due to project conditions and to allow the contractor to complete the work safely. Traffic control measures on Oceanside Blvd. are expected to end in December 2016. Please allow extra time when traveling. The City appreciates your patience during this

important project.




Morro Hills No. 1 and No. 2 Reservoirs Repair Project


Seismic retrofits and structural repairs are needed to both Morro Hills Reservoirs to minimize earthquake vulnerability

and ensure the safety, security, and reliability of the City of Oceanside’s water supply.


Construction work includes seismic retrofits, structural repairs, piping work, pump station relocation, and safety and security improvements. When the repairs are complete, both tanks will receive fresh coats of new paint in a tan color. The construction contractor is required to keep noise levels within regulation standards. The contractor must also control dust levels and ensure trucks do not idle at the project site before, during, or after working hours. The water supply typically stored in the Morro Hills Reservoirs will be rerouted during construction to ensure there will be no disruption in water service. 


Construction Schedule and Hours

February 2017 to Summer 2018

Monday through Friday 8:00 am to 4:30 pm


No equipment will operate prior to 8 am. The contractor may need to work outside the prescribed working hours on some occasions to minimize impacts to the water system. Residents will be notified ahead of time in these instances.

Sewer Pipe Cleaning and Condition Assessment

The City of Oceanside is conducting city-wide sewer pipe cleaning and viewing pipe conditions using a closed-circuit television (CCTV) camera. This important 254 mile-long cleaning and CCTV effort is part of the City of Oceanside Water Utilities Department’s efforts to enhance wastewater flow to ensure a safe, reliable, and efficient wastewater distribution system.


Sewer access, cleaning, and viewing is performed through sewer manholes. A large specialized truck that contains a vacuum, called a Vactor, cleans a segment of the sewer line. A second smaller truck will then access the manhole. There, workers will use a small camera to video the sewer pipe to ensure it's been property cleaned and document potential problems in the pipe. The entire cleaning and televising process generally takes three hours at each manhole. Work days and hours are from Monday through Friday, 7:00 am to 4:30 pm.


The cleaning and televising work will not include the sewer line lateral (the pipe that runs from the home or building to the sewer main which is typically located in the street). It is the property owners’ responsibility to maintenance and repair the sewer lateral.


It is common in the vacuuming process for toilets to bubble and cause minor splashing due to air pressure in the sewer line. If this occurs, a regular toilet cleaning in and around the toilet is all that will be needed when the work is complete.
