Executive Summary:
In 2014, Sonoma Water conducted a condition assessment of the Forestville water storage tanks. This assessment was conducted under water by scuba divers while the tanks were fully operational. The assessment included tank cleaning, a video inspection, photographic documentation, and a report. The report concluded that the tank coating was failing and corrosion of the steel beneath was observed. While an intact coating system will indefinitely protect the integrity of the steel tanks, a failing coating system will result in corrosion and reduction of wall thickness compromising its structural integrity.
This item requests approval of a contract with Olympus and Associates, Inc. for $1,048,875 for construction of Forestville Tanks No. 1 and No. 2 Protective Coating Removal and Replacement.
Discussion:
HISTORY OF ITEM/BACKGROUND:
The Sonoma County Water Agency (Sonoma Water) constructed, owns and operates Forestville Tanks Number 1 and Number 2 Located on Anderson Rd in Forestville California. Tank No. 1 is a 300,000-gallon tank constructed in 1961. Tank No. 2 is a 1,000,000-gallon tank constructed in 1992.
Both tanks were last coated in 1993. Historically, coating systems were expected to last from 20-25 years. After 25 years, tanks undergo a full cleaning, blasting and recoat. These tanks have reached the point where recoating is necessary.
In September 2015, the Sonoma Water contracted with DB Gaya Consulting LLC to assist in preparing construction specifications for the coating system.

Pursuant to Resolution No. 04-0547, the General Manager maintains authority to approve change orders to construction contracts approved by your Board of up to $50,000 each, provided the change order doesn’t affect the material character of the work and the need for the change order results from unforeseen matters which are discovered after the contract was awarded and such modifications are necessary or advisable to complete the project in a timely and efficient manner. In the unlikely event that significant design-related changes are necessary to complete the Project, staff will return to your Board to approve such changes. However, staff request that your Board authorize the General Manager or his designee to approve design changes as may be necessary or appropriate in connection with change orders within the General Manager’s authority pursuant to Resolution No. 04-0547.
