PROJECT OVERVIEW:
The project transfered the transmission capabilities for the western portion of the 978 pressure zone from a water line located within private property easements that are difficult to access, to public right of ways where maintenance and monitoring are readily accessible. To ensure a seamless transition, the water line in Hidden Mesa Road was constructed first from east to west with temporary water connections to maintain continuous water service to customers.
Once the water main in Hidden Mesa Road was completed and taken over transmission duties, the replacement of the water line in Vista Vereda began with reduced size piping for much of the alignment to handle the lower distribution duty of supplying water to residences in the area.
It was anticipated that there would be several temporary interruptions of service of no longer than a day during the transfer from the old water mains to the new ones.
PROJECT COST:
The final project cost was $3,971,059.74.

WHERE:
The project involved installing approximately 1.75 miles of 15-inch-diameter sewer pipeline in easements that cross the properties of Rancho San Diego Village and the Rancho San Diego Town Centre, and in the SR 94 public right of way between Avocado Blvd and Jamacha Road.
WHEN:
The construction Notice to Proceed was issued on March 31, 2019, and the project was accepted as complete by the District on June 30, 2020.
WHO:
Otay Water District
WHY:
Otay Water District provides sewer collection for more than 15,000 people in the Jamacha Basin communities of Rancho San Diego, Calavo Gardens, Singing Hills, and portions of Mount Helix. The District regularly invests in capital improvement projects to assure efficient operations, comply with regulations, and replace aging infrastructure. District capital improvement projects are funded through user rates and capacity charges.
Project Overview:
The Campo Road Sewer Replacement Project is part of an ongoing series of projects to rehabilitate and upgrade the sewer system in the communities served by Otay Water District.
The new pipeline replaced a 10-inch sewer main that could no longer provide adequate capacity for sewer flows in the area. The new 15-inch-diameter pipeline will reduce the potential for sewer overflows, and its new alignment will allow the District to construct and maintain the pipeline without disturbing sensitive environmental areas.
Sewer service was not affected. Sewer pipes were replaced in sections. For example, between one manhole and the next. As the process began, an upstream manhole was fitted with a pump bypass system. Sewage was then moved through a fully contained roadside relay system to the next downstream manhole.
- In consultation with Caltrans, the District had specified night work for this project, with the majority of activity limited to the hours between 9 p.m. and 5 a.m. Temporary traffic control was also specified for project work at the Jamacha Blvd. / SR 94 intersection.
- Steel plates were used to cover open trenches at the end of each work day. Trenched areas were also repaved at the end of the project.
- During construction, some dust and noise was unavoidable.
- Mail delivery and trash collection was not affected.
- To protect the extensive environmental habitat along SR 94 and reduce the need for sound walls, the District limited construction during the nesting season to minimize impacts to sensitive birds near the project. Construction started in September 2017. Pipeline installation was substantially completed in June 2019, which allowed the removal of K-rail on SR 94. Paving for the shoulder of SR 94 was subject to environmental restrictions and Caltrans direction, but was expected to be completed no later than fall 2019. Minor construction activities may occur through December 2019.
PROJECT COST:
The final project cost was $ 11,076,101.12.
