Subject: Engineering Exception Request for Above-Ground Water Line Installation

Dear Paul Wright,

I am writing to request an exception to the standard installation requirements for a water line to
be buried with sufficient cover in a trench as outlined by Utah Administrative Code R309-550-8-
5. Our project involves installing a water line on a steep and rocky hillside, an above-ground
installation is the only feasible solution.

Project Description:
We propose installing the water line using either of the following methods. Both methods will
adhere to industry standards for above-ground installations.
1. Steel Pipe Installation: A 1.5-inch diameter steel pipe installed above ground. The Steel
pipes will be securely mounted above ground using appropriate supports to ensure
stability and prevent damage.
2. Encased Existing Pipe: Encasing the existing 2-inch poly water lines within a 4-inch or
6-inch ductile iron pipe. Encasing the two existing pipes will provide additional
protection and support for the water line while accommodating the challenging terrain.

Justification for Exception Request:
1. Topographical Challenges: The proposed installation area is characterized by a steep
and rocky hillside. Excavating a trench in this terrain presents significant challenges due
to the high risk of instability, rock obstructions, and potential environmental impacts.
2. Safety Concerns: Attempting to trench through the rocky hillside poses substantial
safety risks to construction personnel and may also compromise the structural integrity of
the surrounding area.
3. Alternative Solutions: We have explored various alternative solutions, including using
different excavation techniques and equipment. However, each of these alternatives has
proven impractical due to the unique geological conditions.

Sincerely,
