An image posted on the ‘History of Hawaii Island (The Big Island) in photos’ Facebook page caught my eye. It is an aerial image of a portion of Hilo Bay from NARA (National Archives and Records Administration).
It showed and was labeled ‘Pipe Line, Hilo Harbor, Hawaii, TH, 6 August 1935’. It looked like a pier going out into the bay coming off of Downtown Hilo. I had never seen this before on any images or maps, and certainly did not know what it was.
The land-based connection of the pier was at the northern end of Kaipalaoa (also known as Mokupane and Isabel Point). I had just researched that area of Hilo and there was never any mention of a pier, nor any mapping or photos of it … until now.
Looking at nautical charts, the ‘pier’ extended from the fringing, shallower part of the Bay to the drop-off. Initial thoughts suggested the ‘pipe line’ may mean it was a fueling line (that offshore ships could refuel or it could be a place for ships to offload fuel for the city).
(Somewhat supporting this idea, starting in 1917, Hilo Gas had a manufacturing facility nearby on Ponahawai Street that produced liquid gas from crude oil for local industrial, lighting, and cooking needs. By 1935, the facility could produce 120,000 cubic feet of gas in eight hours. (The plant was destroyed by the May 22, 1960 tsunami.) (Weston))
After further review, it was clear the fuel alternatives – either supplying ships or off-loading from ships – were not viable (there was no land-based evidence of fuel storage in the vicinity).
Then, the prospect of something relating to wastewater disposal came up. Initially, a subtle reference to ‘Sewage Sys’ (and very small square near the railroad track) on the land was noted on a map.
Further investigation led to more information about the ‘pier’ and ‘pipe line’ led to the conclusion that the ‘pier’ in the image was associated with sewer improvements in Hilo.
The word “Sewer” is derived from the term “seaward” in Old English, as in ditches and ravines slightly sloped to run waste water from land to sea.
From an 1857 story in the Commercial Pacific Advertiser it appears that the first sewer facility to be constructed on Oʻahu was a storm drain located at Queen Street at the foot of Kaʻahumanu Street opposite Pier 11. (ASCE)
Despite three outbreaks of smallpox, a typhus epidemic and two cholera epidemics between 1853 and 1895, no other serious actions were taken to improve conditions.
In Hilo, “The old system built in 1905 together with minor improvements and extensions up to 1933 was serving only 2.6 per cent of the city within the old limits (9 square miles) and 0.6 per cent within the new limits (43 square miles).”
“With the increase in population and extension of the city limits in Hilo, the old sewer system was found to be inadequate to meet the growth and expansion.”
“The low areas in the lands of Ponahawai, Waiolama, Waiakea and Kapiolani drained their sewage into the Waiolama canal, Wailoa river and the Kalepolepo and Mohouli ponds.”
“Twenty or more years of house wastes being discharged into these waterways made them dangerous open sewers. The bay areas were simultaneously greatly polluted by the discharges from these two sources.”
“Formal application for a direct grant and loan for the immediate sewerage works program for the city was made on October 19, 1933”. (Hawaii Tribune Herald, Sept 13, 1936)
On January 1, 1935, the Star Bulletin reported, “Hawaii received more than $18,000,000 in federal government’s ‘spending program’ for public works”.
With respect to the County of Hawaii, one of those projects was “A sewer system for the city of Hilo, consisting of an 1,800 foot outfall into Hilo bay, three pumping stations and the required interceptor and laterals.” (SB, Jan 1, 1935)
“The first unit consisting of a pipe 24 in. in diameter, will start near the present outfall and carry along Shipman St, then over Keawe and up Furneaux St, across three blocks midway between Kilauea and Kinoole streets, and back along Kilauea St, as far as the junction at Hualalai.”
“The purpose of this pipe will be to ‘intercept’ all the mains above coming down toward the bay; and acting as a trunk line, convey the pump-in sewage out into the bay 2,000 feet to a new outfall by force of gravity.” (Hawaii Tribune Herald, Nov 16, 1933)
Then, information on the outfall pipeline and ‘pier,’ “Contractor EE Black, who is in charge of Job 870, outfall unit, is now working his men on a 21-hour shift. The men worked until 3 am today in constructing trussels for a distance of 1800 feet into the bay. “
“This is preparatory work for the excavating of trench and laying of 24-inch cast iron pipes.” (Hawaii Tribune Herald, April 4, 1935) On September 4, 1935, the project engineer announced that the outfall was complete.
“The outfall sewer job is well-constructed, and is functioning very well … There was no sign of sewage coming to the surface.” (HTH, Sep 4, 1935)
The Hilo Chamber of Commerce recently suggested that a buoy be put up over the outfall terminal in order to prevent ships from anchoring in its vicinity.” (HTH, Oct 3, 1935) A red buoy was placed the next month. (HTH. Nov 27, 1935)
So, the 1935 ‘Pipe Line’ image shows the brief installation and use of the ‘pier’ above the waterline, while the contractor trenched, then laid, the new sewer outfall. There are no identifiable remnants of that ‘trussel’ structure. There is a remnant of pumping station on the makai side of the highway, just before you get to the Wailuku River – it was completed March 13, 1936.
