Ongoing and New Construction Projects

Projects planned for Fiscal Year 2017 are as follows:

Village Park No. 5 (VP5) Pump Station Replacement
The VP5 pump station was originally constructed in 1974.  It is located in the City of Encinitas on the west side of Encinitas Boulevard, south of Willowspring Drive.  As a result of a District wide 2014 Pump Station Assessment, it was recommended that VP5 be replaced due to its age, the fact that spare parts are no longer supported by the manufacturer and to provide a safer working environment for staff.  VP5 will be replaced with a submersible pump station because they are easier to maintain and operate. 

Leucadia Force Main No. 1 (L1) Replacement Project
The Leucadia (L1) Force Main is one half of a duel parallel force main system which transports wastewater from the Leucadia Pump Station on the District’s campus west along La Costa Avenue to Coast Highway 101.  L1 was constructed in 1979 and is made of ductile iron pipe.  An assessment conducted in 2013 indicated that the section of L1 west of Interstate 5 (I-5) to Highway 101 is being compromised by internal corrosion.  As a result of this evaluation, the District decided to replace the western section of L1.  The project is in the final stages of design and permitting.  

FY 2016 Gravity Pipeline Rehabilitation
As a result of continual Closed Circuit Television (CCTV) inspections of the District’s collection system by Field Services staff, significant defects are being discovered in numerous pipeline segments that require rehabilitation or repair to prevent Sanitary Sewer Overflows (SSO).  These defects are rated and prioritized by staff for replacement, repair or rehabilitation.  In Fiscal Year 2016 (FY 2016), the District budgeted $500,000 to complete corrections of pipeline defects.  The top priority repairs for FY 2016 include the Cured in Place Pipe (CIPP) lining of vitrified clay pipe (VCP) segments in EL Camino Real, Costa Del Mar, Encinitas Boulevard and Hillcrest Drive due to cracking, offset joints and root intrusion.  Additionally, one pipeline segment in Wilstone Street and one segment in Hillcrest Drive will be replaced using the traditional open trench construction method. 

FY 2017 Gravity Pipeline Rehabilitation Project
As a result of CCTV inspections by Field Services staff, significant defects are continuously being discovered in numerous pipeline segments that require rehabilitation or repair to prevent Sanitary Sewer Overflows (SSO).  These defects are rated and prioritized by staff for replacement, repair or rehabilitation.  In Fiscal Year 2017 (FY 2017), the District budgeted $340,000 to complete corrections of pipeline defects.  The top priority repairs for FY 2017 include a section of vitrified clay pipe (VCP) in Caudor Street that has significant multiple cracks and a VCP segment located in an easement off of Doris and Crest Streets that has a major offset joint.  Another VCP line in Mountain Vista Drive that has significant cracks and root intrusion.  Two segments in a VCP line in Quebrada Street that have major sagging with heavy grit and grease accumulation. 

La Costa Golf Course Gravity Line Improvements
During the design phase for the 2016 Gravity Pipeline Rehabilitation Project in September 2015, it was noted that a section of gravity pipeline in the Omni La Costa Golf Course designated for repair was exposed where it crossed San Marcos Creek.  In November 2015, an emergency repair using cured-in-place pipe (CIPP) lining of the exposed section was completed as a temporary structural reinforcement of the pipeline in anticipation of the predicted El Niño weather pattern during the winter.  Due to the complexity involved with the permanent repair of the San Marcos Creek crossing segment and the remaining section of the gravity line in the golf course, other repair or pipeline realignment options will be evaluated. 

Leucadia Pump Station Rehabilitation
The Leucadia Pump Station is located at the District’s campus at 1960 La Costa Avenue.  In 2014, a pump station condition assessment was conducted to evaluate all pump station components (controls, electrical, mechanical, and structural).  As a result of the assessment, it was recommended that improvements be constructed for the pump station.  Improvements to be completed include installing suction piping in the emergency overflow wet well for by-pass pumping; replace broken valve on surge valve air piping and install unions for disconnection; replace check valves; replace scrubber fan housing and fan; spot repair wet well lining; replace fresh air fan and duct with new fiberglass reinforced plastic fan and ductwork; and perform an assessment of the concrete floor and walls in the pump station to determine the existence and extent of potential concrete deterioration. 

Batiquitos Pump Station Solar Panels
To take advantage of a lower electrical rate, solar (photovoltaic) panels will be installed at the District's Batiquitos Pump Station, located on Coast Highway 101, to reduce on-peak energy consumption by 1,500 kilowatt hours.  This project is estimated to save the District approximately $16,000 annually in electric costs.  The estimated cost for installing the solar panels is $37,000.  Therefore, the District will recover the cost of installing the solar panels within three years.  The project is complete. 

Poinsettia Station Gravity Pipeline Project
The San Diego Association of Governments (SANDAG) and the North County Transit District (NCTD) will construct an underground passenger tunnel to link both sides of the passenger platform at the Poinsettia Train Station in Carlsbad.  To accomplish this, the train tracks will be shifted to the west.  As a result, the District will have to extend the casements protecting the Lanikai Gravity Trunk Sewer and Secondary Effluent Force Main (B1) which run under the train tracks.  Additionally, in coordination with SANDAG and NCTD, the District will construct a second parallel encased gravity pipeline under the tracks as part of this project.  This will enable the construction of the second parallel line to be accomplished under the permits issued for the Poinsettia Station project, saving the District considerable time and costs.
