Toilet Decommissioning

2026 Vault Toilet Decommission Gila National Forest

1.0 PROJECT SCOPE OF WORK

Furnish all materials, labor, equipment, supervision, and tools required to perform operations necessary to demolish three existing vault toilets and to decommission and then relocate three other CXT® style vault toilets.

2.0 BACKGROUND

There are six single-hole vault style toilets on the forest that have been identified (Table 1) as requiring demolition. These toilets were installed in mid-late 1990’s, some even earlier, and are reaching the end of their service life. They require sufficient amounts of time and money to maintain and keep them in satisfactory safe working order and environmental compliance.

Some of these toilets were manufactured by Romtec® and consist of a single user, single vault, waterless design with wood, fiberglass, or composite material construction on top of a concrete slab with a 750-gallon polyethylene vault. The Emory Pass Heliport toilet consists of a small fiberglass and wood structure placed on top of a small concrete pad and pit. See photos (Attachment B).

The above ground portion of these toilets are to be demolished and disposed of inside the pumped vault. The concrete apron (if applicable) and upper portion of vaults should be obliterated, disposed of in the empty vault, backfilled, and the area graded to match surrounding area.

There are three precast concrete vault toilets (CXT®) that are to be decommissioned and relocated to a new location (Table 2). These toilets are in a location prone to seasonal flooding events or are not being utilized in their current location. These toilets are CXT® brand “Gunnison” model 6’6” X 14’ 8”, ADA compliant, single user, waterless vault toilets.

These toilets will need to be pumped, removed from their current location, transported to their new location, and installed per the manufacturer’s specifications. The void left in the ground from removal will need to be backfilled and graded to match the existing area.

There is one option item that includes the demolition of one single user Romtec® vault toilet and the procurement and installation of a new CXT® “Gunnison” single user vault toilet (Table 3).

There are no utilities available at any of the project sites, contractor is responsible for providing any and all utilities required for successful completion of the work described.

B. Compact the aggregate base course material with a mechanical whacker‑type tamper until visual displacement of aggregate base course has ceased. Apply sufficient moisture to achieve compaction described above.

C. Install a sand leveling course over the aggregate base course to eliminate high/low spots and provide uniform support across the entire vault base.

3.23 Vault Placement

A. Place the precast vault onto the prepared sand leveling course.

B. The containment‑area end of the vault shall be installed slightly higher than the opposite end, at a slope of approximately ¼ inch per foot of run, to allow the building superstructure to sit higher and allow water to freely drain out from room during cleaning.
