I need a what??? Backflow prevention devices are now a requirement for any building permit pulled in Nevada City, Ca. – See below for the new ordinance now in effect. Don’t worry – we can help!!
The backflow prevention device or BPD is a device that allows water and materials that back up to escape from the cleanout rather than flowing into the home. Your backup prevention device can be installed by Craig Johnson Plumbing.
A sewer BPD is often a mushroom shaped device in the yard near the house or a spring-loaded or weighted cover on a sewer line cleanout near the house and installed on your lateral connection to the sewer main.
THE BOARD OF DIRECTORS OF NEVADA COUNTY SANITATION DISTRICT NO. 1, STATE OF CALIFORNIA, ORDAINS AS FOLLOWS:
SECTION I: The Board of Directors hereby finds and determines as follows:
A. This Ordinance is consistent with and furthers the goals, objectives, policies, programs and implementation measures of the Nevada County Sanitation District Code by requiring sewers to be designed to preclude the backflow of sewage into laterals and/or buildings;
B. Sewer overflows into sewer laterals and private residences can be detrimental to the health, safety, convenience and welfare of our citizens and the community, and can be costly to correct. Sewer backflow can be caused by the introduction of foreign objects into the system; the buildup of grease in the sewer crown at locations where hydraulic jumps occur; high flow rates due to ground or surface water entering the sewer; blockages and undersized sewers. The use of low cost pop-off relief devices is a simple and cost effective mechanism for reducing the potential for sewer overflows into laterals and buildings. Similarly, the use of backflow prevention valves is a cost effective mechanism for reducing or eliminating the potential for sewer overflows into laterals and buildings. The most appropriate and cost effective time to install such devices is at the time of construction or significant remodeling.
SECTION II: Section 7.3 of Chapter 7 of Title 4 of the Sanitation District Code is amended to add the following:
“Sec. 7.3 Plates
The following plates are included as part of this Chapter:
1. Pipe Bedding

6. Backflow. Sewers shall be designed to preclude the backflow of sewage into laterals.
To prevent sanitary sewer overflows for municipal sewer customers, sewer laterals for new connections, significant remodels of 50% or more, and for replacements or repairs made to an existing sanitary lateral shall include:
A.) Installation of pop-off relief devices (pop-off caps) in the caps of all sewer cleanouts on the property.
B.) Installation of a backflow prevention device (backwater valve), to prevent sewage from the main sewer backing up into the private sewer lines due to cleaning or blockages in the main.
Backflow prevention and pop-off relief devices shall be installed as shown in Plate 11 of Section 7.3 of the Sanitation District Code.”
