Agenda Report
North San Mateo County Sanitation District
a subsidiary of the City of Daly City
Meeting Date: June 27, 2022
Subject: Purchase of Mixer-Aerator Equipment for the Wastewater Treatment Plant (WWTP)
Recommended Action
Authorize staff to purchase new mixer-aerator equipment from SPX (Lightnin) in an amount not to exceed $695,200.
Background/Discussion
A critical component of the WWTP are the biological reactors, concrete tanks with mixer-aerator equipment inside that are fixed at the top liquid level. The mixer-aerators are used to diffuse oxygen with incoming wastewater and mix the liquid in the entire reactor. Microorganisms maintained in the liquid consume the oxygen and pathogenic organisms in the wastewater providing the required level of treatment.
The State Water Resources Control Board, the regulator of the environmental permit of the WWTP, is requiring the replacement of this equipment due to its age and operating difficulties. Staff identified two main manufacturers of mixer-aerators: SPX FLOW (Lightnin) and Philadelphia Mixing Solutions, LTD.
Lightnin was chosen as the preferred manufacturer during design due to historically less expensive capital costs and ease of maintenance. The existing equipment at the WWTP are Lightnin type mixer-aerators and staff is experienced with their maintenance and operation.
Fiscal Impact
Sufficient funds are available in the Fiscal Year 2022-23 Sanitation Fund Capital Project 87-920-942- 4536 Plant Aeration Mixer Upgrade for this purchase. Staff is requesting the cost of the equipment plus shipping ($632,000) and a contingency amount of 10% ($63,200).
Summary/Conclusion
Authorize staff to purchase new mixer aerator equipment from SPX (Lightnin) in an amount not to exceed $695,200. Staff is available to answer questions or to provide additional information to the members of the Board.
Respectfully submitted,
Thomas J. Piccolotti Joshua Cosgrove
Director of Water and Wastewater Resources Assistant Director of Water and Wastewater Resources Attachment 1: Aerator Cost Information
Daly City, California
Aerator Cost Information (as of 19 April 2022)
Lightnin was asked to provide budgetary pricing updates for a 30 Hp. and a 20 Hp. surface aerator with bottom impeller to be used in high purity oxygen service at Daly City. Basically, Lightnin was asked to update the costs previously provided for the Daly City aerator replacement project. The cost update was to account for some scope changes to the original Daly City request as well as to see the effects of supply chain issues currently affecting the market. As originally requested, each aerator includes a motor, gearbox, shaft, 8’ x 8’ mounting skid, surface impeller, and rag free bottom impeller. The gearboxes are now specified as Lightnin’s right angle drive, Series 7 models (which are the same units currently installed at Daly City). All materials below the underside of the skid (shaft, impellers, hubs, and all connecting hardware) are now specified as 316 stainless steel while the mounting skids themselves were priced as carbon steel. The skids and shafts are equipped with the hardware necessary to create the water seal required to prevent oxygen leakage at the shaft during operation.
Lightnin provided the following budgetary quote update via email on 15 February 2022. The numbers are FOB point of manufacture, which is Rochester, NY. Installation (including cleaning for oxygen service), sales tax, initial gearbox oil fill, or any process guarantee costs are not included in these estimates. Although Lightnin didn’t specifically state tolerances, I assume that since these are budgetary numbers, the tolerances are approximately +25%, -10%. Lightnin did state that these numbers do reflect the added costs they are currently seeing due to material scarcity or other supply chain issues, at least to the extent that they are seeing them now.
Size/Surface Blade Type Cost
30 Hp. A245 Mixer, complete $123,000
20 Hp. A245 Mixer, complete $99,000
As originally stated, Lightnin has done no detailed design calculations for the Daly City aerators.
Those calculations would be much more detailed than what we’ve done internally and would include liquid level variation effects, unexpected stage geometric effects on mass transfer or mixing, and stage baffling. That said, I do not expect the aerator sizing we’ve selected to change as a result of vendor design calculations. The above costs are approximately 37% and 21% higher than the estimates originally quoted in October, 2021 for the 30 Hp and 20 Hp aerators, respectively.
The Lightnin specifications will require delivery to the Daly City plant site. Delivery costs will be charged “at cost” as accrued by Lightnin. That is to say, Lightnin does not charge a lump sum delivery cost. For estimating purposes Lightnin is recommending a lump sum delivery cost of $26,000 for their scope of supply. Actual delivery costs will be billed as accrued and will depend on how many trucks will be required to make the delivery. The Lightnin estimate is based on 2 trucks which is considered quite conservative.

Agenda Report
North San Mateo County Sanitation District
a subsidiary of the City of Daly City
Meeting Date: June 27, 2022
Subject: Accept $69,181.24 Grant from the State Water Resources Control Board Recommended Action
Staff recommends that the North San Mateo County Sanitation District (NSMCSD) Board accept a $69,181.24 grant from the State Water Resources Control Board (State Water Board) through its California Water and Wastewater Arrearage Payment Program. The program utilizes funds from the American Rescue Plan Act of 2021 (ARPA) to provide financial relief to residential and commercial customers for unpaid wastewater bill debt resulting from the COVID-19 pandemic.
Background/Discussion
The COVID-19 pandemic has made it difficult for many residents to pay their bills. Through $985 million in Federal funding from ARPA, the State Water Board created the California Water and Wastewater Arrearage Payment Program (Program) to provide relief for unpaid wastewater bills related to the pandemic. This funding covers water debt accrued between March 4, 2020, and June 15, 2021, for residential and commercial customers.
The NSMCSD applied for and was awarded $69,181.24 from the State Water Board through the California Water and Wastewater Arrearage Payment Program. The funds received will assist 87 NSMCSD customers pay down their wastewater debt. Customers will be notified that they qualify for a wastewater credit within 60 days of receiving Program funds. Program funds may only be used to cover residential or commercial arrearages that have accrued during the COVID-19 pandemic bill relief period.
Fiscal Impact
The Daly City Department of Water and Wastewater Resources along with the Finance Department will work with the San Mateo County Tax Collector’s office to apply $69,181.24 in credits to 87 property tax bills that are over 60 days past due and were incurred between March 4, 2020, and June 15, 2021.
Wastewater fees are collected annually through the County’s Tax Roll and placed on the property tax bill.
Summary/Conclusion
Staff is requesting that the NSMCSD Board accept this grant from the State Water Board to assist residents in paying their outstanding wastewater bills due to financial hardships caused by the COVID-19 pandemic.
Staff is available to provide any additional information desired by the District Board members.
