he told the WSA. The main problem in the past, he added, is that the Sperryville project has not been ready to proceed.
Redesign Necessary
The plans for Sperryville’s sewage treatment system still require some redesign in order to be acceptable to the SWCB, according to Wilson. He noted, however, that the SWCB wasn’t questioning either the integrity or capability of engineers from two associated firms, Deward Martin and Burchart-Horn, who have worked on the project to date.
When estimates on the lagoon facility came in $800,000 over funds allocated for the project, consultants from Burchart-Horn were asked to see how to cut costs of that system,^ Wilson said. In addition, the engineers were requested to consider other alternatives, including both innovative technologies and conventional systems. They came up with a proposal for replacing the lagoon with a mount, essentially an extremely large septic leach field built up to give more soil area to compensate for the high water table in Sperryville’s flood plain. For collection, they planned on using individual septic tanks with effluent pumps to move the waste water through smaller two-to-four inch sewer lines to the mound.
With the original lagoon system, monthly user fees were expected to run $27 per month. With the cheaper mound disposal method and reduction in sewer lines from eight inch to two or four inch pipe, the monthly charges dropped to about $16 per month, according to Wilson.
