Statement of Work Great Sand Dunes National Park Portable Toilet and Hand Washing Station Placement and Service Vault Toilet Pumping Septic Tank Pumping

BACKGROUND

Park visitation has nearly doubled in recent years necessitating portable toilets to be placed in the dunes parking area and one near the fee booth to accommodate visitors and reduce the burden on the custodial staff during the busy season which is typically May thru September.

Vault toilets in the dunes area, Sand Pit and Castle Creek day use areas may require frequent pumping in the busy months as well as year round service.

The park also has twenty four individual septic tanks some of which are pumped annually and others on an as needed basis. Emergency call-outs may also be needed.

OBJECTIVE

Portable Toilets and Handwashing Stations

At the dunes parking lot a total of eight (8) portable toilets and two (2) handwashing stations are needed; This includes Three (3) standard toilets, one (1) handicap accessible toilet, and one (1) handwashing station at the north end and for (4) standard toilets and one (1) handwashing station at the south end. One (1) portable toilet is needed near the fee booth. These will require pumping and cleaning services four (4) times a week on Friday, Saturday, Sunday, and Monday mornings. Additionally, in the event that the visitor center restrooms are out of service three (3) additional portable toilets, to include two (2) standard and one (1) handicap accessible, and one (1) handwashing station will be needed to be brought on site within 48 hours of notification. Total duration of rental of portable toilets and hand washing stations is 12 months.

Vault Toilet Pumping

The park has three vault toilets (CXT brand, Gunnison model) each with 1,000 gallon capacity that are pumped at least annually. Pumping includes removing all solids and liquids from the vault (breaking up solids as necessary) as well as trash that may have been placed in the vault by visitors. The vaults are located at these locations.

· Dunes Parking Lot: Access by truck with standard hose assemblies possible from pavement.

· Sand Pit and Castle Creek: Located approximately 1.6 and 2.3 miles from the campground along the Medano Primitive Road. Soft sand typically requires trucks receive assistance from an NPS employee and 4wd tractor. In the past, contractors hired to pump these vaults have used either 1,000 gallon or 2,000 gallon, single-axle trucks successfully. Assisting the truck is a slow, gentle process, and under the direction, control and sole-responsibility of the contractor’s driver.

Septic Pumping

The park has 23 individual septic systems with solids tanks ranging in size from 900 gallons to 6,000 gallons. In unexpected circumstances (i.e. system failure), an emergency pump may be required.

Services Needed

· Pump tanks until empty (break up solids as necessary)

· Clean system filters

· Inspect, clean and pump, as necessary associated system manhole/junction vaults

· Some of the Septic Sytems have both a solid and small liquid distribution tank for the leach field.

· All tanks are located near enough to pavement that the truck can remain on pavement and the tank pumped with typical length hose assemblies with the exception of the Visitor Center. In this case, the truck must be backed over a curb and 200’ on a level gravel road to reach the tanks.
