BACKGROUND
This service provides bins for the collection of grit and screenings materials, the subsequent removal of the full bins, related services such as moving bins on Sundays, and taking drying bed material and disposing the materials at the Orange County Waste and Recycling’s (OCWR’s) Frank Bowerman Landfill in Irvine. Grit and screenings materials are continually collected as part of the preliminary treatment process at both Orange County Sanitation District (Sanitation District) Plant Nos. 1 & 2. Drying bed material is similar to materials removed from sewer lines and plant processes, mixed with sawdust. The Sanitation District pays OCWR separately for the disposal fees.
Effective July 2019, Sanitation District Compliance staff are now administering this contract because of new CalRecycle online reporting requirements and necessary internal documentation required as a result. However, the budget line item is still maintained by Operations & Maintenance (O&M), similar to the biosolids budget line item in which Compliance does contract management for O&M’s budget.
RELEVANT STANDARDS
• 24/7/365 treatment plant reliability
• Comply with environmental permit requirements
• Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting
PROBLEM
The current contract for grit and screenings removal expires on June 30, 2020.
PROPOSED SOLUTION
Approve a new service contract for grit and screenings removal based on a competitive selection process.
TIMING CONCERNS
A new contract must be in place prior to the expiration of the existing contract ending on June 30, 2020.
RAMIFICATIONS OF NOT TAKING ACTION
The Sanitation District will be unable to dispose of grit and screenings which are removed continuously from incoming wastewater.
PRIOR COMMITTEE/BOARD ACTIONS
May 2015 - Board approved a Service Contract to Denali Water Solutions for Grit and Screenings Removal, Specification No. S-2015-668BD, for a total amount not to exceed $387,905 for the period June 22, 2015 through July 31, 2016, with four one-year renewal options; and approved a contingency of $38,790 (10%).
ADDITIONAL INFORMATION
The Sanitation District conducted a bid process based on the specifications developed by Compliance staff. Bids closed on March 3, 2020. This contract was competitively bid with three (3) prospective bidders and one (1) bid package being received by the Sanitation District. The bid was evaluated to ensure that it was responsive and responsible. The incumbent company was the only one to submit a bid. Denali Water Solutions has performed adequately over the previous contract period. No price increases were requested during the last contract period of five years, so the total not to exceed of this contract is about $170,000 higher. However, this cost also includes several alternative contingency costs, such as alternative landfills, that the Sanitation District does not anticipate needing to use.
Staff recommends Denali Water Solutions be awarded the contract as the lowest responsive and responsible bidder.
