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.

Description:
The Los Coches Pump Station Project, WO 219, consists of the construction
of a 64 million gallon per day (MGD) pump station on the site
of the District’s R.M. Levy Water Treatment Plant. A new
50 ft x 60 ft CMU building will house five 450-horsepower vertical

will include variable frequency drive units, electrical metering,
and control panels. Yard piping will include cement mortar lined
and coated steel pipe ranging in diameter from 36-inches to 60-inches.
The project will require civil site work to include excavation,
grading, paving and limited landscaping. An enclosed 1,500 kW
diesel generator will be installed for standby power and coordination
with SDG&E will be required for the installation of a 4,000
Amp electrical service station. The work includes demolition of
the existing pump station which consists of four outdoor vertical
turbine pumps, and demolition of an existing metal storage shed.
The construction duration is 375 working days and the Engineer’s

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

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.
