Editor's Notes
- Good morning A few months ago Mason gave a presentation on the hazards of water and Flooding. I thought I would give my presentation on water to, but with a slight twist. So My question is, When is flooding a good thing? Any ideas? When it is a water feature at a pool or a water play are. This particular image is of a water play area notice that there is a minimum of standing water just enough to get wet and cool off. Pool designing is a rewarding aspect of civil engineering. To provide some of my background in pool design I worked for about 4 years for a company in the Phoenix area where all we did was design and build public swimming pools and skate parks. I know some in this audience already know about pool design from the web-site and the pictures in the front office. However I suspect that not all were involved with these pool designs so here is a 5 minute review of pool design.
- Pool designs have evolved from the rectangular competition pools that we grew up with . They had a shallow end, a deep end and maybe a diving area. Today’s pools have evolved to include areas for competitive swimming, family fun pools and lazy rivers. They have water play features, zero depth areas, water slides and some even have wave pools.
- Pool Design or Aquatic engineering as I have heard it referred. Many of these principles could also be used in the design of fountains and water play areas. Here are a few main points. The purpose of the pool is probably the most important will it be a competitive, dive wave, family or lazy river. What does the client want? Do they want specific play features, slides, or other needs. What restrictions does the governing agency have? Some agencies have specific requirements for the disinfectant filter process of the water. What site restrictions are there? Such as soil, overhead clearance, the adjacent properties. Is it an indoor or outdoor pool? There are a whole lot of other design elements for an indoor pool over that of an outdoor pool. What is the budget? What do they project the revenues to be with tis new pool? And of course there are a more things such as time frame for design and construction.
- Here are some examples of the pool systems that you have to design for. The images on the left are gutter systems. The upper one is an example of a deck gutter system. This particular one is for what is known as a negative pool edge. The water level is flush with the top of the wall. The CAD drawing below it is one where the gutter system is in the side of the wall. The center images are of a pool drains, The image on the top is a cross-section of a residential pool, but the concept is the same for a commercial pool with a few differences. The lower image is a CAD drawing of a Main Drain box. The images on the right are return systems. The upper one again is for a residential pool, but it shows how he water comes from the pool drains and gutter systems to the filter system and then back to the pool in the wall inlets, the larger commercial pools also have floor inlets as well. The lower one is a CAD file of a Vortex nozzle for a lazy river.
- There are two main types of filtration systems for commercial pools, the traditional Chlorination and Ultaviolet. To put it simply the chlorine attracts the bacteria, but it has some unpleasant side effects, such as eye and skin irritations. Ultraviolet uses ultraviolet rays to sanitize the water. It typically has a high percent drop in chloramine concentrations. The drawbacks are in their intial costs, but their maintainace limited to an annual replacement of the UV light bulb of about $2,200.
- There are additional components to consider when designing pools. You have the deck drainage system. The site grading and drainage. Now you can either require that the excavation from the pool be removed off-site or you can use it to create mounds on site, natural amphitheaters on site or other uses. Site security. You have to protect unattended swimmers from drownings. The possibility of the use of Grand Stands for the competition swimming or diving competitions. Will the pool walls be straight or curved. They have to be design not to buckle from the soil pressure when the pool is drained.
- This show the Pecos Park pool equipment building layout. You have the pumps, which are in a pit with a float valve which shuts of if the water reaches a certain point and it is calibrated to the pool depth, the filters and the chlorination or disinfection units.
- Here are some examples of pool features.
- Here are some showing various pool elements. As mentioned you have basic water slides, Lazy rivers, , Indoor diving pools, wave pools, Small slides for the younger swimmers, more advance water slides. We even had one pool that had some floating bulkheads installed which created one large pool or 3 smaller pools.
- So to review Water is collected from the drains and the gutter systems. Then it goes through the pumps and through the filtration system, which could either be by chlorine or Ultraviolet . This diagram is for a residential pool, so it is collecting water from a skimmer, in a commercial pool you would have a gutter system. Then if there is one through the heater. Then it goes back to the pool through wall and floor inlets And to water slides and water features.
- Here are a few of the pools that I worked on the design and construction. Superstition Shadows Park Swimming Pool, Apache Junction, AZ Eldorado Park Pool, Scottsdale, AZ And Pecos Park Pool, Phoenix, AZ
- Here are some 3D files that I did to help visualize the pool design. This is Pecos Park Pool in Phoenix
- This one is one is at Greenfield Junior High School, in Gilbert.
- This is a cut away section of the equipment building for the Pecos park Pool in Phoenix.
- If you are interested in skate parks here are a few that I have worked on.
