estimate to be used for bidding purposes only. The Seller will be paid per 1,000-gallon units

TAC 1397 | Liquid Sludge Hauling Services | Issue Date: 02/25/2026

2.2 The Seller shall provide the following information for qualification with the Bid.

2.2.1 Experience in loading, pumping, transporting, and unloading. It is not required that the

(3) similar projects, showing:

3.0 LIQUID SLUDGE HAULING

3.1 Seller shall load the required amount of liquid sludge from Haikey Creek WWTP and transport

it to Southside WWTP where it will be offloaded into the waste activated sludge holding tank.

This is currently done by City of Tulsa staff using 6,000-gallon tankers. At the Haikey Creek

facility, there is a platform where tankers can pull under. Clearance to pull under the platform

is 11’ 5”. A stairway then leads to access to the top of the tanker where the cover to the tanker

is opened and a six-inch hose is placed into the top of the tanker. A pump is turned on, which

transfers liquid sludge from the holding tank into the tanker (See Figure 3). After the tanker lid

is sealed up, a garden hose sprayer can be used to clean off the top of the tanker and hose.

The liquid sludge is then hauled on the 23-mile one-way trip to the Southside Wastewater

facility. At Southside WWTP, the sludge is drained into a holding tank that is near ground level.

This is currently done by City of Tulsa staff by using a hose with a six-inch female camlock

connector that connects to the back of the tanker truck’s six-inch male camlock port (See Figure

4). A water hose is used after completion of draining the sludge to rinse down the drain hose

and camlock port to ensure liquid sludge is not deposited onto city roadways.

3.2 Seller shall be responsible for the loading, transportation, and offloading of liquid sludge

including all other operational incidentals in accordance with this Agreement.

3.3 Any transportation of liquid sludge by Seller shall be done in vehicles or equipment that

contains the sludge in a manner to avoid the possibility of dripping, spilling, scattering, or

leaking onto the roadway. Should mishaps occur for any reason, the Seller shall be responsible

for cleaning up any such liquid sludge or other material to the satisfaction of the City and other

authorities having jurisdiction in accordance with Section 15.0 – Spill Prevention and Control

Plan.

3.4 The Seller shall provide details on the manufacturer volume held by each tanker trailer hauling

the sludge for verification. Details may be provided on a manufacturer’s plate attached to the

tanker trailer or any other means approved by the City.

3.5 All vehicles and equipment shall be adequately cleaned prior to contact with the sludge to avoid

potential cross contamination of previously hauled materials.

3.6 Upon notification that removal operations may commence, the Seller shall commence removal

operations at the minimum gallons of sludge per day within 48 hours following notification.

IFB Rev 02/2024

TAC 1397 | Liquid Sludge Hauling Services | Issue Date: 02/25/2026

3.7 All vehicles transporting liquid sludge shall not exceed the maximum allowable load limit

(pounds) of any road or bridge being used.

3.8 The Seller shall haul sludge evenly through the workday. Haikey Creek WWTP is operated by

staff from 06:00 a.m. to 4:30 p.m. At a minimum, fifty percent of the sludge shall be hauled to

Southside WWTP by 11:00 a.m. each workday.

3.9 Each plant has designated facilities to allow loading and unloading within 15 minutes.

3.10 All haul routes to and from Haikey Creek WWTP and Southside WWTP shall be selected by

the Seller. The City will not pay for any turnpike fees. Highway access between the two facilities

contains the Creek Turnpike, which is a toll road. As of the writing of this IFB the cost of using

a tanker truck to access Haikey Creek WWTP from Southside via Highway 75 to 129th or Olive

via the Creek Turnpike is $4.79 per trip with a PikePass. Accessing Haikey Creek from

Southside WWTP via I-44 to the Broken Arrow Expressway and connecting at US-169 followed

by transferring to the Creek Turnpike and exiting at 129th/Olive is $1.81 per trip with a

PikePass.

3.11 Documentation of the amount of sludge hauled will be supported by the amount of time that

the sludge loading pump runs at Haikey Creek WWTP. The meter reading for this pump will be

sent to the Engineer daily by Plant staff. This will be used to calculate loading times, which will

support haul logs.

3.12 Security at the facility will require badge access to enter facility gates. The Seller will ensure

that all individuals needing access to the facilities complete both the Access Card form and

Background and Prescreen form. These forms can be obtained from the Engineer. Send the

completed forms to the Engineer to get approval by the City. The Seller should try to complete

these forms prior to starting the project to avoid delays in obtaining their personnel access to

the facility. The City will provide a contractor badge to each individual requesting access. If the

individual loses their card, replacement cost will be on the Seller to obtain a new access card.

At the time of this IFB, the replacement cost is $15 per card. Damaged cards will be replaced

by the City at no cost.
