Ongoing and New Construction Projects
Ongoing and New Construction Projects
Projects planned for Fiscal Year 2022 are as follows:
Gravity Pipeline Rehabilitation Project
Field Services Staff continues to conduct Closed Circuit Television (CCTV) inspections of the collection system. As a result, significant defects are continuously being discovered in numerous pipeline segments and manholes that require rehabilitation or repair to prevent Sanitary Sewer Overflows (SSO). Staff uses the Repair Priority List to maintain a priority listing of gravity pipeline and manhole defects requiring repair or rehabilitation. Staff has implemented a system of alternating Fiscal Year (FY) projects between open trench construction and Cured-In-Place Pipe (CIPP) / Cured-In-Place Manhole (CIPM) Lining methods to correct defects. The FY22 Gravity Pipeline Rehabilitation Project will consist of open trench construction to correct 8 defects discovered during CCTV inspections. Out of the 8 defects to be repaired, 5 will include the installation of a new sewer manhole. The manholes will replace existing sewer cleanouts or stub outs that cause infiltration, have root intrusion, no access; or a combination of the three.
Leucadia Pump Station Rehabilitation
In 2014 Infrastructure Engineering Corporation (IEC) completed the District’s pump station assessment and recommended that improvements be made to the Leucadia Pump Station. In September 2016 IEC commenced project design. As the design progressed, the project transformed into a major pump station rehabilitation. The final project includes replacement of the pumps, piping, discharge header and check valve configuration, installation of a permanent submersible pump in the Emergency Overflow Basin and installation of a super-oxygenation system for Hydrogen Sulfide (H2S) / odor control to the pump station. It should be noted that the last major rehabilitation of LPS was completed in July 2006. In February 2020 the Board awarded the contract for project construction to Stanek Constructors, Incorporated. The Notice to Proceed was issued in March 2020. Construction is ongoing. It is anticipated that construction will be completed by July 2021.
Diana Pump Station Upgrade Project
The Diana Pump Station was constructed as a submersible pump station in 2010. The 2018 AMP recommended that an upgrade to the pump station be completed to include a pump control upgrade, main breaker replacement, and a pump replacement. In addition, the pump station does not have an emergency generator for operation during a loss of power. To accommodate the emergency generator the District is working to acquire an easement on an unused adequately sized property that exists across the street.
Encinitas Estates Pump Station Replacement
The Asset Management Plan (AMP) recommended that a pump station condition assessment be completed to evaluate all components (controls, electrical, mechanical, and structural) of all District pump stations. IEC completed the pump station assessment and recommended that the Encinitas Estates Pump Station be replaced with a submersible pump station. Replacing the Smith and Loveless packaged pump station with a submersible pump station will improve operations and maintenance accessibility and provide a safer environment for field services staff. In November 2020 the Board awarded the contract for project construction to Pacific Hydrotech Corporation. The Notice to Proceed was issued in December 2020 with an anticipated project completion in January 2022.
Village Park No. 7 Pump Station Replacement
The 2019 Pump Station Assessment conducted by Infrastructure Engineering Corporation (IEC) recommended the replacement the Village Park No. 7 (VP7) Pump Station because it is approaching its 50 year design life. The pump station was installed in 1973 and is a Smith and Loveless metal can packaged pump station. Because it is nearing the end of its useful life, the mechanical, electrical and structural components require replacement. Instead of rehabilitating the current station, the Pump Station Assessment recommended that the VP7 Pump Station be replaced with a submersible pump station. The replacement will increase collection system resiliency, improve operations and maintenance accessibility and provide a safer environment for field services staff.
