For those who have been working for the past three-plus years to get a new pool constructed in Newton, this is a big week.


The three entities involved in making decisions for the Public Building Commission will all have the authorization of a bond for a pool and Centennial Park renovation project on their agenda.


The board of education met Monday to consider the issue. The city will meet Tuesday, and the Recreation Commission will meet in a special meeting Tuesday morning.


The city agenda contains not only a price tag for the pool project but details of what the city will be asking contractors to design and build.


The Newton Public Pool Improvements project is proposed to cost $2.875 million and, if it can be done under budget, include the following improvements:


• Main Pool: Concrete 6-lane lap pool with a 12-foot deep end and two 1-meter diving boards.


• Concrete decking, 5-inch reinforced.


• New pool filters (sand), pump equipment and lines, and any necessary chemical feed equipment to support the facility.


• Inflatables and a climbing wall.


• Zero Entry space with small leisure pool space, spray features like a water cage and water bucket.


• Shade structures.


• Refurbishment of the existing slide and add a runoff slide.


• A family slide — a slide wide enough for a parent and child to go down together.


• Lazy river.


• Bath house upgrades, including new lighting, new fixtures in, new partition doors, repainting interior walls, doors, and ceilings, new flooring and other improvements.


• A new, secure main entrance, new windows where needed and secured coverings.


• Lighting improvements.


• New fencing.


The city is also anticipating spending about $1.1 million for renovations to existing ball fields at Centennial Park along with construction of two new fields at the facility.


A PBC Interlocal Agreement Addendum was recently approved by the city, Recreation Commission, school district and the PBC. That agreement was signed by all parties and is being sent to the Attorney General’s Office for final ratification.
