Project Update:
Preparation for Land Outfall Connection Continues
Cardiff-by-the-Sea, CA, February 21, 2018
Construction work continues on the Land Outfall Replacement Project by the San Elijo Joint Powers Authority and general contractor, J.R. Filanc. Project information can be found at www.sejpa.blogspot.com and www.sejpa.org.
Here are the key updates on our progress:
- The contractor experienced a minor delay of the dewatering well drilling process due to unforeseen conditions including large rocks and pieces of concrete beneath the beach workpad.
- However, as of February 20th, all four wells were successfully installed and dewatering of the excavation is ongoing. The water leaving the worksite has been tested and is clean, ocean groundwater (see our Improving Our Water Infrastructure blog post).
- The dewatering system includes 4 wells with pumps, a settling basin, a dewatering pipe, and a rock “energy dissipator” to reduce potential sand erosion and ensure public safety.
- Dewatering is a critical step to allow the contractor to locate the exact connection points and install a bypass system on the existing ocean outfall in order to connect the new HDPE pipeline.
- The bypass system will allow for a live connection to the existing ocean outfall, eliminating the need for any interruption in service during connection and switchover from the old land outfall pipe to the new land outfall pipe.
- Excavation is ongoing at the water reclamation facility on Manchester Avenue in order to connect the east end of the new outfall pipeline to the City of Escondido and SEJPA water effluent infrastructure.
Ongoing trenching work in Manchester Avenue is expected through March 2018 and may temporarily impact access to the San Elijo Nature Center. Every effort is being made to reduce any inconvenience to the community.
The San Elijo Joint Powers Authority is a local wastewater and recycled water agency serving the communities of Cardiff, Olivenhain, Solana Beach, Del Mar, and Rancho Santa Fe. This project will safeguard public health, protect the local environment, and preserve public recreation opportunities along the beaches of Encinitas, Cardiff, and Solana Beach. Thank you for your patience while we work to protect our community and coastline.
