The value of the contract is not explicitly stated, but based on the hourly rates and charges for services, it can be estimated. The hourly rate for an operator with a combo unit is $220, and the estimated total for this service is $1,100. The hourly rate for a drain technician with a jetter trailer is $150, and the estimated total for this service is $750. The charges for disposal of storm water and solids are $0.45 per gallon and $125 per ton, respectively. Assuming an average of 100 hours of service per year, the total value of the contract could be estimated as follows: 100 hours/year * $220/hour = $22,000 per year for vactoring services 100 hours/year * $150/hour = $15,000 per year for jet rodding services Assuming an average of 100,000 gallons of storm water disposal per year, the total charge for disposal would be: 100,000 gallons/year * $0.45/gallon = $45,000 per year Assuming an average of 100 tons of solids disposal per year, the total charge for disposal would be: 100 tons/year * $125/ton = $12,500 per year The total estimated value of the contract would be: $22,000 per year + $15,000 per year + $45,000 per year + $12,500 per year = $94,500 per year The contract duration is not stated, but assuming a 3-year contract, the total value would be: $94,500 per year * 3 years = $283,500
