Caring, Fixing, Planning...
Take care of what we have, fix what needs it, and plan for the future! These words are pretty simple but convey the essence of Helix's comprehensive Capital Improvement Program.

In the 50-square-mile area served by Helix, there are about 700 miles of pipes, 22 storage tanks, and the 30-million-gallon underground Grossmont Reservoir located under much of Harry Griffen Park in La Mesa. All of the water for the Valley and other unincorporated areas is treated and tested at the R.M. Levy Treatment Plant in Lakeside.

Cast Iron Replacement Project

 

This is part of the District's continuing cast-iron pipe replacement program. Cast-iron pipe is susceptible to corrosion and leaks, and the District has proactively been replacing the cast-iron piping within the system with PVC pipe. The new PVC pipelines reduce property damage potential, provide our customers with more reliable service and better fire protection, and requires less maintenance by District crews.

In this particular project, the District has contracted with Erreca's Inc. to install 4,250 feet of 8-inch PVC Class 200 pipe in various streets in the City of Lemon Grove. The project is 75 percent complete with an estimated completion date of April 1, 2005. The original contract price was $493,000. Read more...

Windsor Hills "B" Tank Replacement
4165 W. Arrieta Circle, La Mesa.

The existing prestressed concrete reservoir was built in 1958. A 1988 study indicated that the Windsor Hills "B" Tank did not meet current seismic standards and the roof was cracked.

 

The report also noted that the Windsor Hills "B" Tank is considered the fourth most strategically important reservoir in the District's system. Replacing this reservoir will meet current seismic standards and ensure a sound system to serve the public.

The work consists of the demolition and disposal of an existing 1 million-gallon prestressed concrete potable water reservoir and associated piping, and construction of a 1 million-gallon welded steel potable water reservoir.

The work includes associated foundations, pipeline, valves, storm drains, site work, tank coatings, cathodic protection system, modifications to existing hydropneumatic pump station and tank located on-site, site paving, irrigation piping, landscaping, and fencing.

Design of the tank replacement is expected to be completed in March 2005, and advertise for bids from contractors in April 2005. Construction is expected to start in May 2005 and last about 9 months. The Engineer's estimated construction cost is $1.5 million.


Construction of Homelands Pump Station:
2050A Greenfield Dr., El Cajon

This project involves the construction of the Homelands Pump Station on a new site next to the Greenfield Tank. This facility will replace the old Homelands Pump Station which was abandoned after the relocation of the Flume Transmission Main in 2000.

 
 

The new pump station consists of three 125 horsepower pumps, which will restore a permanent primary service to the Homelands area east of El Cajon, as well as provide backup service to neighboring areas. The pump station project includes associated site improvements, installation of piping, valves and other mechanical/electrical equipment. The facility will be housed in a masonry building that has been designed to mitigate both noise and visual impacts to the surrounding community.

Construction of the pump station, which started in July 2004, is expected to be completed in May 2005. The Contractor is Ryan Company and the construction contract is $1.3 million.


Construction of Moreno Lakeside Pipeline:

 

The Moreno Lakeside Pipeline (MLP) is a joint project between the San Diego County Water Authority and the Helix Water District. The pipeline is a new 4.7-mile raw water transmission main consisting of 54-inch and 60-inch segments of cement-mortar-lined and coated steel pipe.

This pipeline will augment the District's raw water transmission capacity from the Authority's raw water Aqueduct No.1, and will ultimately allow for the District to receive water from the San Vicente Reservoir. The pipeline will have a capacity of 80 mgd, of which 40 mgd is reserved for Helix WD.

The pipeline project includes an interconnect vault which connects the MLP to the District's other raw water transmission mains near the R.M. Levy Water Treatment Plant to provide additional raw water delivery flexibility to the treatment plant. Construction of the MLP Project began in Fall 2002 and will be completed by the end of February 2005. The Contractor is Archer Western Contractors. Construction cost is $18 million.

Replacement of Filter Valves at WTP:

 
 

This is a District project that involves replacement of five 30-inch filter influent valves and six 16-inch filter surface wash valves at the water treatment plan. This replaces the valves that were in continuous service since the initial construction of the treatment plant in 1963.

The valve equipment was procured by the district in mid 2004 and was installed by District treatment plant personnel in November 2004. Because this project replaced the original valves, which were worn and required much attention, everyday operations and maintenance is enhanced with the installation of the new equipment. Project cost is $160,000.
