Back in January, Ikaika Anderson, Romy Cachola, and Ann Kobayashi traveled to San Francisco to check out that city’s sewage system.

Their reports were distributed to colleagues last week, and are likely to factor into the City Council’s discussion of the Synagro contract tomorrow afternoon.

Here are the key excerpts from the three reports:

Cachola (submitted March 12) — “The systems in operation at Oceanside and Southeast show that largescale digesters, when operated in conjunction with a waste-to-energy facility, are an efficient and effective means of treating sewage sludge. Similarly, I believe that it would be in Honolulu’s best interests to carefully consider a similar facility to treat our own sewage sludge.”

Anderson (submitted Feb. 8) — “The experience of visiting these two facilities and having an opportunity to speak with facility staff made it clear that Honolulu’s failure to employ co-generation technology at its wastewater facilities, especially at Sand Island Wastewater Treatment Plant, has resulted in a significant lost opportunity to help reduce operating expenses.”

Kobayashi (submitted Feb. 7) — “With the use of egg-digesters at San Francisco’s Oceanside Water Pollution Control Plant, it is evident that the City and County of Honolulu can utilize other proven technology other than the one being implemented by Synagro.”
