Canaan has two sources of water
Canaan Street Lake and drilled deep well.
Sign at the water resevoir: shows image of lake and mentions swimming and boating restrictions  Wellhead pipes extending from ground.

Two types of natural contaminants:
normal lake water contamination and radon from deep water well.

Two strategies for removal of contaminants:
drawing showing the 3 layers of a filter: sand, gravel, and underdrain.
Lake water is treated by sand filter and chlorinated.
Well water is treated by blending with lake water to reduce radon trace levels.


Strategy for reduction of chlorine and chlorine residuals:
Use less lake water by blending well water Black pipe with valve handle.

Storage and Distribution:
Water is stored in 286,000 gallon storage tank.
Water is transmitted by pipeline throughout the village to 158 residences and businesses.


  • Individual septic tanks process solids through bacterial degradation and then discharge fluid to municipal system.


    • red pump next to white pump station building.
  • Collection sewer lines transport to a pump station on Depot Street.


    • Block-like building with blue garage doors.
  • Pump station pumps liquid to Wastewater Plant behind transfer station.


    • Small square body of water surrounded by a fence.
  • Lagoons aerate effluent as it comes into wastewater plant to increase dissolved oxygen.


    • Construction crew shaping stone mounds for rapid infiltration bed pits.
  • Treatment plant transfers the fluid that has been aerated to the Rapid Infiltration Beds.



  • Rapid infiltration Beds are like large leach fields:
    they return the treated fluid to the ground.



    • Flowers growing around a pipe extending from the ground.
  • Canaan Wastewater pumps the tanks on the system to remove the decomposed solids which are cured and dried in sludge beds at the wastewater plant and then tilled into the soil.


    • Muddly looking pond.
  • The plant's septage beds also accept septage from other non-municipal septic tanks located in the Town of Canaan.


Summary

The primary issues for the previous year were chlorination residuals levels in the water and their impact on dissolving lead and copper in older plumbing systems. The key to improved water was to decrease the use of chlorine. The Canaan water system has addressed these issues by changing water sources and managing chlorination better. The last three quarters of testing (since the improvements were made last year) show dramatic improvement.

    • Residuals from chlorination may be a cancer risk if they are too high. The Canaan water system has been actively working to reduce the use of chlorination through the use of deep water wells and better metering of chlorine. The results during the last year show no tests that exceed state recommended levels.
