Municipal Wastewater

Cities can choose from the following methods to construct a new wastewater treatment plant (WWTP).

Standard Method

  1. Select and hire a consultant through a selection process to manage the Standard Method.
  2. Select and hire another consultant to provide a Feasibility Study of options to meet National Pollutant Discharge Elimination System (NPDES) permit standards.
  3. Select and hire one or more consultants to provide Value Engineering studies to estimate the cost of 3 processes and determine least cost process.
  4. Select and hire one or more consultants to provide an Alternative Design.
  5. Select and hire an engineering consultant to design and engineer the wastewater treatment.
  6. The engineering firm completes plans with estimated costs that meet a city’s budget with 20% contingency.
  7. This budget must meet financing offered by government loan/grant agencies.
  8. Cities generally hire another consultant to prepare the bid documents which is normally for a cost not to exceed construction.
  9. Once a contractor is selected, the city must hire a Qualified Engineering Manager to oversee the construction project and assure compliance and performance to the city.
  10. In this Standard Method, the cities generally take on all the liabilities of construction and plant performance.
  11. There is no overall Performance Bond required for the Standard Method.

Request for Proposal (RFP) FP-DB

City may choose to eliminate most of the steps from the “Standard Method” above.

  1. Cities have the authority to advertise bids using a RFP to procure engineering and construction of a WWTP.
  2. Cities utilizing this RFP Method can require respondents to offer fixed bids for technology, engineering, construction, and a performance bond which will guarantee the highest quality effluent.
  3. Cities can make broad requirements in the proposal so they can obtain a variety of designs which will meet government mandated regulations.
  4. Upon receiving responses, cities retain control of selecting the best quality option if it meets NPDES permit standards to be eligible for State/EPA financing.

Compared to the Standard Method, the RFP Method places most of the liability on ACWT rather than the cities, provides the best available technology, and accomplishes their completed WWTP in a shorter timeframe at a lower cost.

RFP for FP – DBOOT

EPA has stated the privately-owned wastewater treatment are keeping up EPA’s Clean Water Act and municipals are not. Cities are the major contamination of our rivers and bays. The RFP Method process is emerging as our governments are running out of money and municipal wastewater treatment processes are becoming more sophisticated.

  1. The process begins similarly to the RFP Method for an FP – DB project.
  2. The private company will finance the plant and assume the liabilities of planning, construction, operation and maintenance while also maintaining ownership.
  3. There will be an option at the end of the contract for the private company to transfer ownership back to the city.

ACWT can offer cost information to help cities develop the best plan for their citizens
