Planning Project

Old pumphouse at the Cumberland Spring

Name of Project: Planning and Engineering Analysis for Renovations of the ACWD storage tank and water sources

Funding was awarded in Nov. of 2015 for "up to $300,000". The project's main objective is to find the least expensive way to provide safe drinking water to the town of Alleghany by either replacing or eliminating the need for a treatment plant.   The planning project included the following tasks: Drill test wells, collect and analyse water samples, and perform pumping tests to locate a groundwater source which can provide the community with sufficient potable water. 

The project also includes finding a secondary water source (redundancy) and the design work necessary to replace the water system’s aging tank, which is (was) in poor condition and has a non-compliant tar-based liner.

Engineering and environmental work necessary for the construction phase of all components will be completed. 

The planning component for the tank replacement project was completed in early 2017 and that portion of the planning project has moved to construction. (Is now its own construction project)

The vertical test wells were drilled in late 2016 but the water quality was not acceptable and they were abandoned. The planning project then went back to ACWD's original idea which was to improve the Ram Spring where the town currently gets its water via horizontal drilling.

In May of 2017 driven pipes were installed at the town’s existing water source: the Ram Spring to see if it would  eliminate surface water infiltration. This project was succesfull and the division of drinking water permit for this water source was changed from "ground water under the influence of surface water" to just "ground water". Water quality data is being compiled to help determine the treatment needs for this source.

A potential secondary water source: the Cumberland Spring which is owned by the water district, and was used in the past is being studied to see if it meets water quality standards for ground water. This study is complicated by unstable ground around the Cumberland Spring site.

Because of the failure of the test wells and the need for additional water quality testing and engineering the funding for this project was increased from "up to $300,000" to "up to $500,000" in 2017 and the completion date was extended to mid 2019.
