Monday the EID board unanimously approved $51,000 for surveying, geotechnical studies, design studies and environmental studies.
“Staff has performed preliminary investigations and determined that the elimination of the Mormon Island, Lake Ridge Oaks and Ridgeview 7 lift stations is feasible,” the staff report stated.
Instead the plan is to install gravity lines to divert wastewater away from the lift stations and direct them to a nearby downhill station.
Costs have not been totaled up yet for the new sewer lines plus removing the existing lift stations, but “eliminating these lift stations will also substantially reduce the cost of operations maintenance.”
The sewer lift stations generally last 25-30 years and currently cost about $1 million each to replace and rehab, including generator backup.
“Sounds like a good idea, if we can eliminate three lift stations at a million dollars a pop,” said Director George Osborne.
