Woodmoor Water and Sanitation District, March 13 – New technology for sewer maintenance

By James Howald

At its March meeting, the Woodmoor Water and Sanitation District (WWSD) board approved a more efficient way to identify sewer lines in need of maintenance. The board awarded a contract for a sewer saddle replacement project and heard a request from a resident to buy land from the district. The board heard operational reports, and the meeting ended with an executive session.

Acoustic wave technology improves efficiency

Operations Superintendent Dan LaFontaine told the board about a new technology using acoustic waves that could reduce what the district spends on its “repair and replace” strategy for sewer lines. Currently, WWSD has divided its service area into five zones, and each year the lines in one zone are inspected by video camera and cleaned. It takes five years to inspect and clean all the lines in the service area, LaFontaine said.

LaFontaine explained a new method that uses devices that send and receive acoustic waves between manholes. The distortion in the acoustic waves is used to determine how clear or clogged a line is. LaFontaine said the Monument Sanitation District and the Palmer Lake Sanitation District have switched to this approach with good results.

LaFontaine said the technology would allow the district to inspect all five zones in one year instead of five years. Invasive tree roots are a costly problem, LaFontaine said, and a faster schedule would be more effective in dealing with them.

President Brian Bush recommended inspecting all lines annually. Director Barrie Town pointed out that using a schedule was not efficient because some lines were cleaned solely because they were on the schedule, not because they needed cleaning.

Director Town moved to add funds to the sewer line budget item, and the board voted unanimously in favor of his motion.

Contract awarded

District Engineer Ariel Hacker reviewed for the board the details of a contract to replace 30 service saddles (vertical connectors that join residential lines to mains), five gate valves, and three fire hydrants. The contract includes asphalt replacement, traffic control, and customer notification.

Hacker said Caraveo Construction Inc. had submitted the low bid for the job at $187,711. She noted there were two other bids—one for $295,000 and the other for $480,000. The range of bids was very wide, she said, adding Caraveo Construction was already working on another job for the district.

The board voted unanimously to accept Caraveo Construction’s bid and authorize Bush to sign a contract.

Resident offers to purchase land

During the public comment portion of the meeting, resident Dave Easton told the board he was interested in purchasing land adjacent to Monument Academy from WWSD. He said he had made a similar request several years ago.

District Manager Jessie Shaffer told Easton the district typically doesn’t sell land. Bush said he would be surprised if the current or a future board agreed to sell land belonging to the district.

Highlights of operational reports

  • Construction of new well 19 is due to begin in April.
  • The Chilcott Ditch is being cleaned in anticipation of beginning to deliver water to ditch customers later in the spring.
  • Classic Homes is expected to have model homes in the Monument Junction East development built by June.

Executive session

The March meeting ended in an executive session to consider strategies relative to negotiations and receive legal advice concerning pending litigation.
