This swimming pool is shallow and narrow. It's shallow so there are many accidents of hitting the bottom while diving. As there are many lanes, the pool narrowed. So there are many crashes while swimming. First, we can make the water level deep by heightening the bottom. We can dig in the ground, but there is a parking lot underground so this is difficult. So we can make the water level deep by raising the height of the bottom. Next, we need to reduce just one lane to reduce the width of swimming pool. Then, it becomes the width of international standard.

The swimming pool is shallow and narrow. Shallow water causes many diving accidents where people hit their heads on the bottom. They tried to make many lanes as possible, making the pool narrow. It causes many collision accidents while swimming. First, we can solve the depth problem by increasing the height of the floor. They can try digging  up the bottom of the pool, but it's difficult because there is a underground parking lot under the pool. So, you can make the depth deeper by increasing the height of the floor. Secondly, they can remove just one lane to increase the width. This meets the requirements of the international standard.
