I don't know anything about swimming pools, but would it be an option to drain the pool at the end of each summer and use it as a sunken garden area in cooler weather? Surround the pool with a permanent strong, decorative barrier as a safety measure to stop people from falling into the pool and create a wide series of steps to enter the pool if you don't already have some. (if the steps don't span the breadth of the pool, then add handrails at each side for safety).
You could cover the pool base with rubber or artifical grass to protect it, add seating; flashy pot plants, decorative lights, grill or gas heater, etc. To save water, you could pump the water out and store in a tank somewhere unseen so it isn't wasted, or offer it free to a local business.
Once you're ready to use the pool again, roll up the artifical grass or other covering to store elsewhere, then refill the pool.
