REPAIR WATER LEAK AT US COAST GUARD BASE SAN PEDRO

  • Client: US Coast Guard
  • Location: Base LA Long Beach, San Pedro
  • Date: 2016
  • Contract #: HSCG88-16-J-PQQ167
  • Value: $96,165

Project Details

Coast Guard Base LA/LB was experiencing low water pressure at four of their buildings on base. Cerrudo Services located all the underground water piping system that feeds domestic cold water from the water meter to the four buildings.  A leak was discovered at the base of a fire hydrant.  The hydrant was dug out by hand and removed from its base.  The valve seat was cleaned of built up materials and reassembled.  The unit was tested and no further leaking noted.  Gravel was placed around the valve body for drainage, the excavation refilled and compacted, and the surface restored.

A second leak was discovered near the wharf in front of Building 14. Upon visual inspection for damaged piping under the wharf, rushing water was noted coming out of the sea wall under the rip rap.  The north section of the base was isolated with a new 6″ gate valve so work to repair the lead could commence without cutting off domestic water from the base.  The exact location of the leak was identified near an existing tee. The area was controlled for traffic and the asphalt cut back.  A 3″ steel pipe was discovered at an abandoned electrical vault located at the edge of the tee fitting.  There was a clean shear at this point.  The concrete ring that caused the shear was removed and the vault was backfilled with sand.  The failed fitting was removed and replaced with a schedule 80 PVC tee and compression pipe couplings.  Installation was tested at line pressure for 30 minutes with no leaks.  The area was back filled and compacted and new asphalt installed.

  • Client: US Coast Guard
  • Location: Petaluma, CA
  • Date: 2016
  • Contract #: HSCG88-15-J-PFP005
  • Value: $312.125

Project Details

The existing north galley beverage line and cold bar was in very poor condition and needed replacement.  The existing scullery was dismantled , moved and reinstalled at project completion including all water supply lines, electrical connections, booster pumps, steam piping and stainless steel ventilation ducting.  Then the beverage line, cold bar, counters, concrete pad and floor tile were demolished along with associated electrical and plumbing connections.

Two existing floor sinks and 25 LF of deteriorated drain piping were replaced and all existing drain lines were snaked back 50 feet from the beverage line.  A subsequent modification required replacing four additional floor drains and drain piping.  A new sanitary line with P-trap was connected from the new floor sink to the existing sanitary line, with 3″ sand below and above the piping, and backfilled with compacted class 2 AC road base.  A 4″ thick, 2,500 psi concrete slab was placed over the backfill.  New tile was installed to match existing.

The new 27′ x 7′ beverage line is a modular, 14 gauge stainless steel serving line with cup dispenser, beverage line, cold bar and soup/condiment dispenser.  The line was installed including all piping, wiring, receptacles, floor sink, drainage system and Coke dispenser.  Reinforced doors were installed below the line for storage and equipment access.  A new filtered copper domestic water supply line was located in the middle of the beverage line.

REPAIR DOMESTIC HOT WATER SYSTEM – US COAST GUARD TRAINING CENTER

  • Client: US Coast Guard
  • Location: Petaluma, CA
  • Date: 2016
  • Contract #: HSCG88-16-J-PFPMW1
  • Value: $55,024

Project Details

The existing cement lined hot water tank, approximately 750 gallons, was originally heated with a hydronic tube bundle.  The tube bundle was removed and replaced with a 670 MBH water heater in 1990.  In recent years, the old tank was discovered to have the cement liner breaking up and falling to the bottom of the tank.  The existing heater had no storage capacity and an 80% efficiency rating.  After the cement liner was tested and found not to contain asbestos, the tank and associated piping, valves and electrical were removed.  A new 125 gallon, 400 MBH propane fired condensing water heater was installed along with a new “smart” circulator and expansion tank in the mechanical room.  All utilities to the system including a PVC exhaust vent through the flue opening from the old heater were connected.  A new floor sink with 2″ drain was installed.  All hot water components were insulated.  Start-up of the new system was provide by a factory certified technician.

CAMP PENDLETON RESERVOIR CLEANING AND DISINFECTING

  • Client: US Navy
  • Location: Camp Pendleton, CA
  • Date: 2013
  • Contract #: N62473-08-D-0505-0005
  • Value: $3,007,055

Project Details

Cerrudo Services, as sole subcontractor to Alutiiq International Solutions, provided environmental service work at 30 reservoirs. Cerrudo cleaned and disinfected the water reservoirs and ensured they are ready for use. The reservoir structures are both in-ground and above ground structures. Prior to cleaning, Cerrudo performed a reservoir/tank inspection providing information to identify and evaluate current and potential water quality problems. Both interior and exterior inspections were employed to assure the reservoir/tank’s integrity, security and high water quality. The inspection included visual inspections of structural and non-structural members, coverings, pipe and drains, and equipment and components.

The reservoir surfaces to be cleaned and disinfected varied from concrete, steel, polypropylene lined and redwood. Cerrudo developed a cleaning schedule with the order and time frame in which the reservoirs were cleaned. The work required an approved Confined Space Entry Plan prior to performance of the work. Although the reservoirs are easily accessible, most are located in remote areas.

Cerrudo removed all sediment from the reservoirs, and hauled and disposed of the sediment at 3-Mile Pit near the Base. Rinseate (pressure washing by-product) was disposed at the nearest Waste Water Treatment Plant.

Cerrudo used Chlorination Method 2 when chlorinating the reservoirs. The chlorination time requirements were coordinated with the filling of the reservoir/tank by the Base Water Department. The reservoirs were disinfected with a chlorine solution of at least 1,000 mg/l, and allowed to set a minimum of 24-hours after application of the chlorine solution before being filled.
