Safeguard Your Water

What is Cross- Connection Control?


Cross-connection control is simply a program that is designed to take the safeguards necessary to protect one of the world’s most essential assets…water.  Only through education and the combined cooperation of the public and your water purveyor, the City of Bastrop, can we ensure a safe supply of drinking water.

The City of Bastrop’s Water distribution system is designed to keep the water flowing from the distribution system to you, the customer.  However, when hydraulic conditions within the system deviate from the “normal” conditions, water flow can be reversed.  When this backflow or back-siphonage occurs, water can enter the distribution system.


The Texas Commission of Environmental Quality and the City of Bastrop require the installation of a backflow prevention assembly to any establishment or residence where a potential contamination exists.  (ie: anything that is hard-plumbed into the City’s water supply.)  It is further required that all assemblies installed to safeguard against potential health hazards be tested annually to ensure they are working properly.  For non-health hazards, including assemblies installed on irrigation/sprinkler systems, testing is required every three years.


 A backflow assembly is an approved, testable assembly which uses valves in different configurations to prevent polluted or contaminated water from reversing direction and flowing backward. 


Keeping water safe from potential contamination is easy.  Take the following precautions to protect your drinking water.


NEVER submerge hoses in buckets, pools, tubs or sinks.


ALWAYS keep the end of the hose clear of possible contaminants.

     (Such as:  Pesticides, Fertilizer, Weed Killer, etc.)


DO NOT use spray attachments without a backflow prevention device.  The chemicals

     used on your lawn are toxic and can be fatal if ingested.


DO buy and install inexpensive backflow prevention assemblies for all threaded

     faucets around your home.  They are available at hardware stores and home-

     improvement centers.
