North Beach Water District

The water system was formed by the merger of two investor-owned water systems (Ocean Park Water Company) and (Pacific Water Company). OPWC was founded in 1962 and had initial plans to serve 300 customers. The first water system plan was completed in 1966. The ownership changed in 1979, by 1998 it had expanded to serve over 2,000 customers.

PWC was originally formed as Ocean Bay Water Company in 1970. Ocean Bay Water Company was formed utilizing existing aging infrastructure from the vacated Rushlight dairy farm (AKA John Paul dairy farm). The first water system plan for Ocean Bay Water Company, completed in 1981, planned to serve 279 customers. Ocean Bay Water Company was purchased by PWC in 1987.

In 2004, PWC and OPWC entered into an intertie agreement by which PWC would construct a reservoir and water transmission line to provide fire flow to OPWC. Construction of the intertie was completed in May 2007.

Also in 2004, the North Beach Public Development Authority (NBPDA) was formed to assist the community of Ocean Park to acquire ownership of the water utilities serving the community. In February 2006, the NBPDA acquired ownership of both PWC and OPWC, and the combined system was named North Beach Water.

A water system plan for North Beach PDA was completed in 2008. Later in 2008, the NBWD was formed, ownership of the North Beach Water system was transferred to NBWD, and the NBPDA was disbanded.

Filters at both sites need to be backwashed to remove trapped particulate matter. Two pumps at the NWF site and one pump at the SWF site are dedicated to filter backwash. Filter tanks are backwashed one at a time by switching valves on the tanks to allow reverse flow through the tank. Backwash water from each facility is discharged to a nearby depression where it percolates into the ground.

The NBWD has a total of four reservoirs. All reservoirs are cast-in-place concrete Mount Baker Silos. Three reservoirs are located at the NWF site, and one reservoir is located at the SWF site.

The NWF reservoirs were all constructed in 1990. All are 26 feet in diameter by 45 feet tall, with nominal capacities of 179,000 gallons each.

The SWF reservoir was constructed in 2006, and is 30 feet in diameter by 50 feet tall, with a nominal capacity of 211,000 gallons. The combined total gross storage volume is 748,000 gallons. All reservoirs are equipped with interior and exterior ladders with access control, locking access hatches, screened downward-opening vents, and exterior water level indicators. Each reservoir is valved separately from the system to allow for isolation of any reservoir for service.

The storage reservoirs are not tall enough to provide adequate system pressure by gravity, so all water must be continuously pumped into the water distribution system to maintain system pressure.

The NBWD has two booster pump stations, one located at each well field. The NWF booster pump system consists of eight electric motor-driven booster pumps ranging in power from 5 hp to 25 hp. Pump station discharge pressure is maintained at 60 psi by a 6-inch pressure-reducing valve on the pump station discharge header. A pressure relief valve recycles water from the pump discharge manifold to the pump suction manifold when the pressure in the discharge manifold exceeds 90 psi.

The SWF booster pump system consists of four electric motor-driven booster pumps: two 10-hp pumps and two 40-hp pumps. The two 10-hp pumps are controlled by variable speed drives such that the pump speeds vary to maintain a constant system output pressure of 60 psi.

Four emergency standby generators are provided to keep the water system operating in the event of a power outage. Two 150 KW diesel generators are located at the NWF, one Katolight and one Caterpillar. One 150 KW Katolight diesel generator and one 30 KW generator are located at the SWF. All four generators have automatic start and power transfer capabilities on loss of power to the site.

Based on system mapping, the water distribution system consists of slightly more than 56 miles of water mains ranging in size from 2 inches to 12 inches. Over half of the system is a 2-inch water main. Almost 18 percent are 6-inch and just over 15 percent are 8-inch water main. Table 1-5 summarizes the system water distribution system by size.

Transmission and distributions facilities consist of over 56 miles of pipes ranging in size from 2 inches to 12 inches in diameter. Piping installed prior to 1980 was a combination of asbestos concrete (A-C) pipe and polyvinyl chloride (PVC) pipe. In the early 1980s the standard was changed to a minimum of 160 psi pressure rated PVC pipe.

Oysterville

This water system is located north of NBWD, and serves a development known as Espy Ridge Tracts. Information regarding this system was obtained from the WFI form for this system, updated June 14, 2013. The WFI indicates that the Oysterville water system is owned by Oysterville Water NP Corp., a homeowner’s association.

Surfside Homeowners Association

This water system is located north of NBWD and serves the Surfside Estates subdivision and several smaller neighboring developments. Information regarding this system was obtained from the WFI form for this system, updated on November 6, 2013. Surfside Homeowners Association, a non-profit corporation, owns the Surfside water system.

City of Long Beach

This water system is located south of NBWD and serves the City of Long Beach. Information regarding this system was obtained from the WFI form for this system, updated on November 15, 2013. The City of Long Beach water system is owned by the City of Long Beach, a Code City.

NBWD currently has no interties with neighboring water utilities. To make an intertie viable, the water mains feeding to the intertie location need to be capable of conveying enough water to make the intertie feasible. Currently, there is a separation of approximately 1.2 miles by road between adequately sized water mains in NBWD and Surfside HOA water system, approximately 2 miles between NBWD and Oysterville Water, and approximately 2.7 miles between NBWD and City of Long Beach water mains. The cost of installing water mains of these lengths makes interties impractical currently. When development brings existing water mains closer, interties may become feasible in the future.
