Lawn Sprinkler Permit
|
When is a
Lawn Sprinkler Permit Required? |
A lawn sprinkler permit must be obtained before
installing any lawn irrigation system that is permanently connected to the
City’s water supply. A lawn sprinkler permit is not required when making
repairs to the piping of an existing lawn irrigation system unless the
back flow prevention assembly is being replaced.
|
Where Do I Go to
Obtain a Lawn Sprinkler Permit? |
Sprinkler permits may be obtained at the Public Works
Department located in the Water Tower at 7800 Virgil Anthony Sr. Boulevard.
|
How Do I Obtain a
Lawn Sprinkler Permit? |
You must complete and submit an application to the
Public Works Department. A contractor may do the work if
licensed by the State of Texas as a lawn irrigation contractor and is
registered with the City of Watauga. Homeowners may do the work themselves
and no special tests or registration is required. However, in order to
install your own lawn irrigation system, you must have filed a Homestead
Exemption Certificate with the County Tax Office or present proof that you
currently own and occupy the dwelling.
|
How Much Does a Lawn
Sprinkler Permit Cost? |
The fee for a lawn sprinkler permit is $33.50. This is
subject to change.
|
How Long Does It
Take to Get a Permit? |
Normally, a sprinkler permit is issued while you wait.
However, the amount of time varies based on the complexity of the work,
but generally you can expect same day service.
|
Is There Any Special
Equipment Required for a Sprinkler System? |
Yes, in order to protect the public potable water
supply, you must install an appropriate back flow prevention assembly
(double-check valve) in accordance with State Plumbing Regulations.
Rain and freeze sensors are also required.
|
What Are the
Requirements for a Double-Check
Back Flow Prevention Assembly? |
A back flow prevention assembly box must be set
back with a minimum of 12” of gravel below the bottom of the box (see
Figure A).
There must be a minimum clearance of 6” on each
side of the double-check assembly and the box (see Figure B).
From the handle tip of the double check gate valves,
there must be a 3” clearance to both sides of the box (see Figure B).

Where Should I
Install the Double-Check Assembly? |

to the water meter as possible.
|
Upon Installation of
the Sprinkler System and Double-Check Assembly,
Are There Any Additional Requirements? |

final inspection by a licensed back flow assembly tester, and a report given
to the City.
