Garberville Sanitary District Working to Replace Chlorine Contact Chamber Before Summer Water Demand Hits Hard
Garberville Sanitary District has been working hard to replace the chlorine contact chamber at our water treatment plant that failed the day after Thanksgiving in 2017 and are optimistic that we will have a contact chamber installed before July of this year so that we can meet the water demands of our customers during the hot months of summer.
A chlorine contact chamber is where chlorine is mixed with the water before it leaves the treatment facility. The State Water Board requires a calculated amount of contact time with chlorine before they consider water safe to drink, so we are working with them to provide sufficient disinfection and contact time to meet safe drinking water standards.
Part of the problem with the contact chamber which failed, is that it was underground and we were unable to visually know if a problem was occurring. The new contact chamber will be above ground, so that this type of event will not happen again and if a malfunction occurs, we will be able to make repairs prior to complete failure of the system.
Currently we are providing water by bypassing the failed contact chamber and using our existing 8” water transmission pipe from the treatment facility to Garberville for contact time before it reaches human consumption. The State agrees that this meets the required detention time for safe potable water but we can only operate at one third of the gpm our treatment plant is capable of and this is not enough water to meet the summer demands.
Contrary to statements in social media, we have no alternative motive for replacing the contact chamber, we are not increasing District boundaries nor are we attempting to provide water to any other entity.
Our only objective is to repair or replace what was damaged as inexpensively as possible and provide safe drinking water to our customers while meeting their water demands.
