The Price River Water Improvement District Board voted to hire WaterWorks Engineers to design and oversee work on the district's proposed $7 million construction projects.
The engineering fee was agreed not to exceed $1.64 million.
In another vote, the board accepted the bid of Lewis Young Robertson & Birmingham, Inc., to perform an impact fee and rate structure analysis. The Salt Lake firm specializes in municipal financial consulting. This is not to exceed $21,999.99.
Both contracts anticipate the approval of all or part of the planned improvements by the Permanent Community Impact Board.
PRWID is requesting half the amount in grants and the other half in long-term, low-interest loans
For its share, PRWID will put up $100,000 for the water proposal and $50,000 for waste water treatment.
That improvements include $5 million for the culinary water plant at Castle Gate and $2 million for the sewage plant at Wellington. Pipe extensions and improvements for water and sewer systems are included in the tab.
Environmental requirements make up the most expensive single investment at the Castle Gate plant. PRWID has to inject a lot of chlorine into the water leaving the plant so that there will be some chlorine remaining in the pipes at the far end of the system. While chlorine kills bacteria, it also combines with the organic material left over to form undesirable byproducts.
The options for fixing this run in the $2.5 million range, whether it be a system for removing the organics at the plant or using ozone to cut the amount of chlorine needed.
The water plant also needs various upgrades to bring it up to its intended capacity of 6 million gallons a day. It now runs at 4 million because there wasn't enough money 30 years ago to put in all that was necessary. While the flow is adequate most of the time, there is no extra capacity to keep the water flowing out if there are problems such as turbidity during runoff or heavy rains.
The most expensive items at the sewer treatment plant are mainly replacements of equipment and structures that are wearing out.
