Another service of the Water Reclamation Division is treating public sewer lines to control roaches. This is a free service. To request this service, you may call the Cockroach Hotline at 873-7009, or you may make an Online Cockroach Prevention Request. The Water Authority receives up to 60 requests per day from April through September, so crews may require more time to spray a specific area during these months.

An Ongoing Effort

The Wastewater Division provides an ongoing effort to prevent cockroaches in the Water Authority's sanitary sewer manholes. All of the 34,000 manholes are treated twice a year for infestation. The product used to control the roaches is boric acid. Approximately one pound of boric acid is sprayed into each manhole through a hole in the center of the cover. The process does not require lifting the cover. While boric acid is very effective in killing cockroaches, it is not toxic to humans or animals.
