1.0 OVERVIEW & PROJECT DESCRIPTION

This project will remove sludge and inorganic materials from a wastewater basin at the West Lakes District Wastewater Treatment Plant (WWTP) at Glacier National Park. The main wastewater basin, after more than 20 years in service, has an estimated 6.5 feet of settled sludge and inorganic material settled at the bottom of the basin. The sludge interferes with pipes and valves that connect the basin to the wastewater plant building.

This contract is limited to sludge removal and related activities only – the basin liner and all WWTP equipment shall remain unchanged.

All field work shall occur at the West Lakes District Wastewater Treatment Plant – 427 Barn Road, West Glacier, MT 59936. This is located just past the West Entrance Station of Glacier National Park.

A firm, fixed price contract shall include all preparation, mobilization, facilities, management, labor, equipment, materials, permitting, and other costs incurred to complete the requirement as defined under Section 3.0 Scope of Work.

Refer to Section 2.0 Existing Conditions for a description of the existing conditions for each CLIN. Refer to Section 8.0 Attachments for a list of materials and data provided by NPS.

2.0 EXISTING CONDITIONS

2.1. WLD Wastewater Treatment Plant

2.1.1. Main Basin

a. HDPE liner

b. 12’ width concrete access ramp

c. Aerated (two surface, two downdraft)

d. Decant structure

e. 2:1 side wall slope

f. 366’ x 126’ at the high water level of 9 feet

g. Approximately 2,130,000 gallons = 285,000 cubic feet capacity at high water level

h. Estimated average sludge depth of 6.5’ and TSS of 31,700 mg/L, an estimated total of 183 tons of sludge, based off measurements and calculations recorded by the wastewater plant operators in Summer 2025.

i. A small amount of sludge is removed from the basin each year, but the basin has not been thoroughly cleaned since the wastewater treatment plant opened in 2003. Expect heavy inorganic materials (trash pumped out of vault toilets) mixed in with the sludge.

2.1.2. Winter Basin

a. HDPE Liner

b. 12’ width concrete access ramp

c. Not aerated

d. Approximately 350’ x 157’ at side water level of 12’

e. 3,397,600 gallons = 454,160 cubic feet capacity

f. Estimated sludge depth of up to 2 feet above the drain in the northeast corner of the basin (on attached plans, at 3165.80 feet); due to the basin’s slope to this drain, approximately one-half of the area basin contains an amount of settled sludge.

2.1.3. Residuals Drying Basin

a. 8’ side wall depth

b. 2:1 side wall slope

c. 502,475 gallons = 67,175 cubic feet capacity at high water level

2.1.4. Estimation Note

a. Please note, these numbers are only a rough estimate and not guaranteed; the Contractor is solely responsible for determining the effort required to remove all sludge from the Main Basin and Winter Basin.
