Council authorizes purchase of replacement dome for water plant south digester
Summary
The council adopted an emergency ordinance authorizing purchase of a replacement outer dome for the south digester at the water pollution control plant; staff said lead time is about a year and the supplier change was required because the previous vendor stopped supplying the covers.
Defiance City Council on March 24 adopted an emergency ordinance to purchase a replacement outer dome (gas-membrane cover) for the south digester at the water pollution control facility.
Mr. Mack told the council a different manufacturer will supply the dome because the previous vendor stopped producing the covers. He said the lead time for delivery is approximately a year, and that the purchase does not include installation labor. When asked about warranty and lifespan, staff said the dome comes with a one‑year warranty and that projected lifespan was not specified in the meeting record: a councilmember asked, “Is there a warranty on this and a projected lifespan?” and the reply was recorded as “a one-year warranty” and “I am not sure what the projected lifespan is.”
Council discussed the dome’s purpose as an exterior weather and UV protective canopy for the digester; staff said it helps to maintain pressure in the digester and reduce the chance of larger problems. Staff also said the city would budget separately for installation labor at the next budget cycle; the transcript includes a phrase describing that installation would be an additional “27 expense,” but the record does not specify currency units or the fuller amount.
The council voted to suspend the rule and adopt the ordinance as an emergency. The transcript does not record specific contract dollar amounts or a projected lifespan for the dome.
What happens next: staff will proceed with ordering the dome so long lead time does not delay replacement; installation and final labor costs will be handled during budgeting and are not included in the purchase price recorded in the meeting.
