SSWA Capital Improvement Program

The SSWA Capital Improvement Program (CIP) is included in the SSWA annual budget and includes three types of projects:

Rehabilitation Projects


These projects rehabilitate or improve existing facilities including equipment replacements, facility modifications not connected with capacity increases for development, system replacements (including service replacements in conjunction with Suisun City road rehabilitation projects) and studies to plan rehabilitation projects (such as condition assessments). The Replacement Reserve, which funds replacement projects, is itself to be funded by transfers of water rate revenues from the Operating Fund and interest income.

Capacity Fund Projects

Capacity Fund Projects plan and add new facilities to the SSWA system including construction of new facilities such as treatment plants, storage tanks, and pumping plants, as well as studies to plan these major facilities, including the Water Master Plan. The Capacity Fund provides funding for capacity studies and projects and is itself funded by development impact fees and interest income.

2016 Bond Fund Projects


On September 13, 2016, the Suisun-Solano Water Authority sold 30-year bonds yielding a deposit of $9,500,000 into the SSWA 2016 Bond Fund. These funds will be used for rehabilitation projects in the Capital Improvement Program, in effect accelerating the rehabilitation of the SSWA water system. The bonds will be repaid by water rate revenues.

The near-term focus of the SSWA CIP is to provide treatment capacity needed for existing and planned development within the Suisun City General Plan area. Planning for a complete rehabilitation of the system is the long-term focus; this includes physical projects and their funding. Studies of the SSWA infrastructure included a condition assessment and rehabilitation plan for the Cement Hill Water Treatment Plant; a System Design Review to confirm how much water SSWA will need; a Water Loss Control Program Plan to cut the real and apparent water loss from our system; and a condition assessment and rehabilitation plan for the existing distribution system facilities. The information provided by these investigations was used to refine the scope and estimated cost of the CIP.

Since 2012 SSWA has invested significant funds in rehabilitating the equipment at the Cement Hill Water Treatment Plant including new plant electrical and control systems, filter media replacement, clarifier and tank rehabilitation and painting of major structures.  Planned projects include, among other things, a new storage tank, rehabilitating existing storage tanks, replacement of main pumps, treatment chemical systems and metering systems, rehabilitation of distribution system facilities like tanks, pumps and pressure reducing stations, and replacing customer meters with addition of an advanced metering infrastructure system and customer information system.
