2008 - 2017 Capital Improvement Program
| Project #8018, Blue Lake Plant Improvements | |
Description: This project consists of replacing the existing gaseous chemical effluent
disinfection system with liquid chemical disinfection; modifying the existing
aeration tanks and solids handling facilities to remove phosphorus;
rehabilitation of facilities nearing the end of their useful life; improvements
to the solids processing facilities and odor control; the addition of anaerobic
sludge digestion to supplement the existing sludge dryer for reliability and
capacity; and improvements to plant utility systems, including standby power.
The project also includes the staged expansion of the plant's capacity. |

In addition to meeting the regulatory requirements of the NPDES permit, the improvements provide the additional treatment capacity to meet long term service needs of the service area.

The plant's O&M costs will increase by approximately $120,000 annually due to the conversion to liquid chemical disinfection. Other plant O&M costs will increase as capacity is increased. Annual solids processing O&M costs will be reduced by over $1,000,000 with the addition of anaerobic digestion prior to heat drying, due primarily to energy cost savings, but total annual O&M costs will increase with increasing wastewater flow and solids production.
