Report to Redding City Council February 12,2025 Re: 4.12(c)--Award BN No. 5555 Buckeye Water Treatment Plant Filters 5-8 Repairs Page 2 Alternative Actzon City Council (Council) may choose not to award the bid for the project and provide staff with alternate direction. Without this project, there is greater potential for increased maintenance costs, a decrease in reliability, and an increased risk of failure of the filters at the Buckeye Water Treatment Plant that could impact the City's customers. BackgNound/Analysis The Water �Utility treats raw drinking water through a filtration and disinfection process at its two water treatment plants (WTP) —Foothill and Buckeye. The Buckeye WTP treats raw water from Whiskeytown Lake and is located on Benson Drive, northwest of the City boundary. It was built in 1993 and a major expansion was completed in 2008. The Buckeye WTP includes eight �lters, four of which were added in the 2008 expansion. The underdrains in the four original �lters (filters 1 through 4) were replaced in 2005. In 2019, the underdrains in filters 1 through 4 were already failing, so the City replaced the existing plastic filter underdrain systems with new stainless-steel underdrain and air-scour systems manufactured by AWI. Staff has been pleased with the durability and operation of the stainless-steel underdrain and air-scour system and on June 4, 2024, Council approved a sole source designation for the AWI filter underdrain systems at the WTP's. The four filters that were added in the 2008 WTP expansion (filters 5 through 8) still utilize the plastic underdrain systems and staff is concerned about their reliability and longevity. Of those, filters 5 recently failed and is currently out of service. This project will replace the plastic underdrain systems in �lters 5 through 8 with new AWI stainless steel underdrain and air-scour systems to match the installations in filters 1 through 4. Attached is a tabulation of bids received and opened on January 23, 2025, for construction of the project. The low bid in the amount of$576,500 was received from RTA Construction, Inc., of Redding, California. The engineer's estimate was $845,000. Total project development costs for this project are estimated to be $30,000. Project development costs include engineering and environmental for the project. Environmental Review Staff has determined that the project is categorically exempt from environmental review under California Environmental Quality Act Guidelines, pursuant to Sections 15301 - Existing Facilities. Class 1 exemptions include the minor alteration of existing public structures and facilities. The project will repair or replace existing infrastructure in the same location and serving the same purpose and capacity. Therefore, the project has no potential to have a significant effect on the environment and further environmental review is not required.

Backg�ound/Analysis The Public Works Department - Water Utility treats raw drinking water through a filtration and disinfection process at our twa water treatment plants (�TP) — Foothill and Buckeye. In Fiscal �Year 201$-�19; at the� Buckeye��WTP, four filter underdrains constructed in 2005 had failed and� were replaced. The original underdrains that failed were Roberts brand plastic underdrains and �were replaced with�a stainless-steel underdrain and�air-scour�system manufactured by AWL AWr has been in business since 19�8 and their underdrains are manufactured in the United States. Staff�is pleased with the durability and operation of the stainless-steel�underdrain and air-scour� syste�n compared�to the plastic�underdrains�. Report to Redding City Council May 29,Z024 Re. 4.12(c)--Authorize the Sole Source of Filter Underdrains toAlNi Page 2 The remaining four plastic underdrains at the Buckeye WTP were constructed in 2008 and staff is concerned about their longevity. Of those, filter #5 recently failed and the Public Works Department - Engineering Division is preparing to release a capital construction project to replace those four-filter underdrain and�ir-scour systems. Staff is requesting Council to make a sole source finding that would allow the AWI underdrains to be specified in ��the plans and specifications. By matching��existing equipment, �it minimizes �training and maximizes maintenance efficiencies including stocking of spare parts. In �accordance�with Public C�ntract�Code Section 3400(c)(2)�., the Council m�y make�a�n�ding for a ��material,product, or�service�by�spe�ific brand or�trade�narne�in order to match other�products in use within the City of Redding's water syst�m. Such a finding would a11ow the benefits described above to be realized. �F.IZVl1"OIZYIZe12rCl'l�RBVl��„Yz�;t+'r�i�r:�s3z r tJ�i � t } r i �r t s 71 ss }t �iii ��'"'t`' � f s't ��r t {tr `iY�t`�i Thi s activit y i s �� pro j e ct a s d e��{� b y the Calif ornia En vir onm ental Quali�y Act (CE QA), and�no further;��n is requlred at tl��me.
