BACKGROUND/DISCUSSION:
Biosolids are nutrient-rich organic materials resulting from the treatment of domestic sewage in a treatment facility. When treated and processed, theseresiduals can be recycled and applied as fertilizer to improve and maintain productive soils and stimulate plant growth. The Calera Creek Water Recycling Plant (CCWRP) produces mostly Class "A" but a minimum Class "B" biosolids at an average of 100 wet tons per month during dry season and an average of 150 wet tons during winter.
In order for CCWRP to meet the regulatory disposal requirements for biosolids, the decanter centrifuge is used to dewater or remove the liquid from the digested sludge produced in the treatment process. After the digested sludge goes through the centrifuge process, the dewatered sludge is essentially the biosolids that is easier to handle and costs less to transport.
Currently, CCWRP operates on two centrifuges - both are Centrisys Decanter Centrifuge Model No. CS-18-4. The first one was purchased in July 2011, while the second one was in March 2015. The centrifuge is critical to the solids handling process, and although CCWRP operates on one centrifuge at a time, it is important that both are in running condition to provide Pacifica City Council 2

redundancy. The Model No. CS-18-4 centrifuge technology is proprietary to Centrisys CNP, and only qualified service technicians from Centrisys are authorized to work. Therefore, all past maintenance was and all current maintenance will be performed by qualified Centrisys service technicians.
The Centrisys Decanter Centrifuge Model No. CS-18-4 should be annually serviced and repaired by Centrisys CNP qualified technicians from Centrisys CNP due to the following reasons:
-The original parts and accessories are proprietary to Centrisys CNP, and the Centrisys Maintenance and Repair in Stockton, California is the only authorized repair facility in northern California.
-Centrisys CNP technicians have the expertise on Centrisys Decanter Centrifuges. ,
-Centrisys repair facility has a proven track record of a quick turn-around time on repairs.
Crucial for redundancy at CCWRP.
Pacifica’s Purchasing Policy (Administrative Policy No. 76), as set forth in Article 7 Exemptions From Competitive Pricing, Section 7.4 Sole Source Purchases, authorizes the City Manager to waive bidding requirements for a sole source purchase and services when sufficient justification exists. As sufficient justification exists, the City Manager recommends approving a resolution that authorizes the City Manager to award and execute a Master Services Agreement with Centrisys CNP for a sole source purchase, approves a total project budget of $175,000 and authorizes staff to execute future task orders not to exceed the project budget.
ALTERNATIVE ACTION:
The Council may choose not to approve the Master Service Agreement with Centrisys CNP for the CCWRP Centrifuge Project. However, this could result in future repair delays and possible increase in cost. Staff does not recommend this alternative action.
RELATION TO CITY GOALS AND WORK PLAN:
Approval of the Master Service Agreement with Centrisys CNP is consistent with the following Council adopted Goals:
• Improve and steward City infrastructure, streets and facilities: The Project will support the City’s wastewater treatment plant’s dewatering process which will ensure proper disposal of biosolids and protect the environment.
