Wallace Lakes Estates water tank replacement advances after condition and water-quality concerns

The Calaveras County Water District has filed a Notice of Exemption for replacing the potable-water storage tank serving Wallace Lakes Estates in Wallace, citing the existing tank’s poor condition and water-quality issues.

The filing, dated June 8, 2026, describes a proposed project for the rural residential community in Calaveras County. The work would replace both the existing tank and its concrete foundation, while temporary storage is used during construction.

Temporary storage planned

CCWD proposes demolishing the existing approximately 230,000-gallon tank and its concrete foundation. The district plans to install three temporary tanks, each with an 8,000-gallon capacity, while the replacement work takes place.

The planned replacement would have approximately the same capacity as the existing facility: about 230,000 gallons. It would be a glass-lined, bolted-steel tank built on a new concrete foundation.

Using temporary tanks is intended to support water storage for the Wallace Lakes Estates system while the current tank is removed and the replacement is built. The project concerns that community’s water system; it does not establish that water service throughout Wallace will be interrupted.

Project footprint and site conditions

The construction would disturb approximately 10,000 square feet of previously disturbed land. The project site is also in an area classified as having high wildfire exposure on the California State Fire Marshal’s map.

That wildfire classification describes the site’s environmental setting. The reasons identified for replacing the tank are the existing facility’s condition and water-quality issues. Those concerns do not, by themselves, establish contamination or a public-health violation.

For Wallace Lakes Estates residents, the proposed work represents a change to the community’s potable-water storage infrastructure. If carried out as described, the project would remove the current tank, construct a new foundation and replacement tank, and use temporary storage during the transition.

What happens next

The Notice of Exemption documents the proposed project and its construction arrangements, but it is not a construction completion notice. The filing does not state a construction start date, completion date, project cost or anticipated service interruptions.

CCWD’s filing identifies Wallace Lakes Estates as the service area for the project. The next practical milestones for residents will be the district’s construction scheduling and any project-specific notices about work activity or changes affecting the community’s water system.
