CITY OF MOLALLA, OREGON

WASTEWATER TREATMENT PLANT


TECHNICAL Contractor shall provide to the City the following services:

1. Scope of Work. a. The Contractor will provide labor, materials, supplies, and equipment to dredge,

dewater, haul away, and dispose of an estimated 6000 Bone Dry Tons from Lagoon 1, Lagoon 2, and the Aeration basin. Contractor will dredge and screen the solids prior to use of dewatering equipment. Contractor will then transport the dewatered solids to a designated disposal site.

2. Process Description a. CONTRACTOR will draw the slurry from screening tank to at least two (2) belt presses

which measure at least 1.7meters. Each belt press shall be fed using a its own feed pump capable of at least 300350 gallons per minute. Contractor will use a variable frequency drive (VFD), and regulate the speed control of these feed pumps, in order to achieve continuously optimum pumping rate to the belt press. The belt press equipment itself must also have its own onboard feed pump to allow for process optimization.

b. A polymer make down system shall be used, allowing for the mixing and hydration of polymer flocculent, which shall be used to aid the separation process. The hydrated and aged polymer shall be metered using a VFD driven positive displacement pump. The VFD shall be used to achieve a precise flow regulation of the polymer so that the correct dose is added for optimal separation while minimizing waste.

c. The slurry and polymer flow will both be measured using magnetic flow meters and the polymer will be added to the slurry with a static inline mixer to blend the two, based on the flows. The polymerized slurry will then be injected into the belt press where the separation will take place.

d. The CONTRACTOR will maximize Belt Press output, cake dryness and capture, while minimizing polymer dosage during all phases of the project.

e. The liquid portion of the dredged material will exit the belt press and will drain by gravity through at least one polishing tank, and finally back into Lagoon 1 (no water will be pumped directly into Lagoon 2). The cake or solids portion will drop onto a conveyor and be transported in 20 yd. bins or 2 axle trucks. The Contractor is responsible for ensuring trucks and transfer equipment is able to be used on the lagoon dikes, and no equipment shall at any time pose a risk to the dikes.

3. Schedule and Personnel on site a. CONTRACTOR may plan to operate 10 hours per day. No work shall be performed on

Saturday or Sunday. No labor, parts, or assistance from the City will be supplied, and the Contractor shall not request such from city Staff. Interactions with the Wastewater Treatment Plant operators will be limited to coordination for the purpose of adjusting, or cease, dewatering processes to meet the Treatment goals of the plant.

b. Contract schedule compliance is critical. For the year 2018 the Contractor will execute the contract with the City within five (5) working days of July 1st 2018. The Contractor shall be on site with all machinery, tool, apparatus and working no later than July 10th. For the remaining years of this contract, the contractor will perform work within the schedules noted in that year’s notice to proceed.

4. Measurement of Bone Dry Tons a. Two samples of cake or solids will be taken from each load. One sample will be analyzed

by CONTRACTOR using a Moisture Analyzer to determine the % solids content. The other sample will be retained for the City’s Wastewater Treatment Plant Operators to test in the City’s laboratory. Contractor will mark all samples given to the City with time and date it was drawn. If there are any discrepancies between the solids content derived by CONTRACTOR and that found by the City’s lab, the City’s lab will be assumed to be correct. The % solids will be multiplied by the net weight of each drop box load as shown on the landfill truck scale tickets to determine the dry tonnage per load. CONTRACTOR will compile a truck log that will sum the dry material removed on a daily basis with a running total showing project to date. Each log entry will also show the TAIL NUMBER and GROSS VEHICLE WEIGHT that hauled the load. The following formula will be used:

Dry tons = Net Drop box weight (lbs.) x Cake Dryness (%)

___________________________________

2000 lbs. /ton

5. References a. Contractor will supply references for at least the Project Manager who will be on

site during the whole project, and who has attended the pre-bid meeting. 6. Special Conditions

a. The contractor will provide analysis and testing of biosolids required by the landfill of choice, and be approved for disposal of dewatered biosolids by that landfill. The Contractor will supply copies off all analytic results, permits, and letters of permission generated.

b. All operations by the contractor will be done in such a way as to minimize or eliminate odor.

c. All precautions necessary to protect the earthen dikes from any operations, including trucking, dewatering, or returning water back to the lagoons, shall be observed by the contractor.

d. The contractor will coordinate with City Forces during all phases of the contract to ensure any actions taken do not disrupt the treatment plant or cause problems with the plants’ NPDES permit compliance.

e. The contractor shall plan and methods and means of transporting all equipment into position onto the lagoon levies. NOTE: temporary access road construction from HWY 211 will not be possible due to wetlands.

f. The Contractor may plan to use the 460v, 300 amp power located at the inlet of Lagoon 1.

g. The contractor shall haul all biosolids per bid Schedule to approved landfill. h. Contractor will be responsible for all site cleanup, leaving the plant in good

condition at the end of each years dewatering and hauling operations.

i. The City’s Project Manager will have the authority to halt work due to City operations, weather, spillage, mechanical or treatment problems at the wastewater treatment plant.

j. The OAR 340 Division 50 rules and EPA’s 40 CRF Part 503 regulations regulate the City’s biosolids program. All biosolids to be hauled and applied are Class ”B” biosolids.

k. A Project Manager for the Contractor shall be designated and be responsible for biosolids hauling and application coordination. The Project Manager will be on site during the project.

l. The Contractor is responsible for any and all coordination, communication, and work performance of its subcontractors. Under no circumstances will the City be asked to work directly with a subcontractor unless the City determines it is in its best interest to do so.
