1. How is the water in NSPs treated?

A. The water in NSPs is treated biologically. No chemicals or devices are used that would disinfect or sterilize the water. The water is ensured clean by the movement of it through the biological filter, the action of the aerobic and anaerobic bacteria in the filter and regeneration zone as well as the plants fed hydroponically. In short it's Mother Nature's method of cleaning and clarifying water. We are simply building an environment that allows her to do what is natural – and – enhancing that environment with design techniques and energy-efficient technology.
2. How big does the regeneration zone need to be?

A. There are technically 5 different "types" of NSPs and they differ depending on the exact design of the swimming zone and the regeneration zone. However, a good rule of thumb is that the regeneration zone should be approximately equal in size to the swimming zone.
3. Can I heat the pool?

A. Yes – but the question, up to what level, depends on the climate and the time of the year. Natural Pools tend to be warmer than traditional pools. This is because the regeneration zone is relatively shallow and acts as a passive solar collector. Write back for details on heating in your area.
4. Do NSPs act as a breeding ground for mosquitoes?

A. No. Natural Pools set the water in motion and mosquitoes are not a problem as they do not breed in moving water.
5. Do these pools cost more than traditional pools?

A. In general, yes. These pools cost about the same per square foot as a traditional chemical pool. However, since these pools are larger they may cost more, typically starting out in the high five figure range. Additionally, natural pools need to have the aquatic plants acquired and installed, however on-going operational costs are lower over the years as no chemicals are needed and energy consumption is much lower than for a chemical pool. Finally, it should be considered that the NSP is not just a swimming pool but also a water garden.
6. Can we have fish in the pool?

A. No, although fish would love to live there. Fish put an undesirable biological load on the system and are not permitted in order to meet our standards.
7. Will there be algae?

A. Yes, an alga is a natural plant and an NSP will always have some algae in it. Alga is simply a single cell plant and a small amount of algae in the regeneration zone of the system is actually necessary. We control algae by using the correct aquatic plants for the climate to insure that these plants out compete with the algae for the available nutrients in the pool water. Algae are typically relegated to the regeneration zone and are vacuumed out of the swimming zone with a pool vacuum or automatic pool cleaning system.
8. What kind of maintenance is required?

A. To an extent maintenance is the same as for a traditional, chemical pool. We need to periodically empty and clean skimmer baskets, empty and clean pump baskets, vacuum the pool and clean the filter. Water garden maintenance is also necessary – removing unwanted plants, trimming and maintaining existing plants and cutting them back at the end of the season
9. We have freezing weather in the winter, what about winterization?

A. In cold climates, the NSP needs to be treated just like any other pool, i.e., the plumbing lines need to be winterized, and the pump and filter drained. The swimming zone can be covered with a winter cover and the regeneration can be covered with a mesh to prevent leaves and other debris from entering the area.
10. What is the minimum size for an NSP?

A. We do not recommend NSPs smaller than 535 square feet in total. Consult our technical team for details on correctly sizing an NSP.
11. Who designs and builds my pool?

A. Your pool can be designed in a number of different ways including either with your Architect or a trained landscape designer working closely with you or you could just rely on us.
12. What should be the size of a balancing tank?

A. Typically the balancing tank size of a swimming pool is 6% to 8% of the volume of the swimming pool.
13. What should be the size of a filter room?

A. A thumb rule of 1sqm per 10000L of water with a minimum size of 6'x6'. Height of filter room should be sufficient for person to stand inside and operate & maintain the system.
14. What is ozonation? How sufficient a method is it?

A. Ozonation is an alternative to chlorination. Although ozonation system is a better way of chemical treatment of water, some amount of residual chlorine is still required.
15. What is UV treatment?

A. UV treatment is an alternative to chlorination.
16. What are the standard shapes of swimming pools?

A. Please see our standard shapes gallery for various swimming pool shapes. A standard residential pool is approximately 20'x40'x4'.
17. Can I add fish to my water body?

A. Addition of fish requires a bio filter and UV treatment. Contact our equipment supply department for a BOQ of filtration items required for fish.
18. My swimming pool is leaking - what should I do?

A. Leakages in pools/water bodies are a standard problem. The water may leak through civil structure, broken pipelines or electrical wires/conduits. Contact our service cell to identify and rectify your problems.
19. What is the standard depth of a swimming pool?

A. Standard depth of pools - Main Pool - 4' Kids Pool - 1.5' Jacuzzi - 2.5' - 3'
20. Should I go for a skimmer type or overflow type pool?

A. A skimmer type pool is typically a system followed for small pools (surface area <= 75 sqm). An overflow type pool with an overflow gutter all around the pool is a better system for pools which are >= 75 sqm. An overflow type pool looks better and bigger than a skimmer type pool.
21. Is a balancing tank necessary?

A. A balancing tank is necessary for an overflow type pool. A skimmer type pool does not require a balancing tank.
22. How do I decide the size of swimming pool required?

A. As per international standards the size of the pool depends on the bather load. Approximately allot 2 sqm of water surface area per swimmer as per international standards.
23. How do I design a swimming pool on a terrace?

A. We recommend a service floor/area for a swimming pool on a terrace. Furthermore we recommend that the pool/water body be cast independently - ie the floor of the pool and the terrace slab should be independent.
24. What is the size of a typical Olympic size pool?

A. 25m x 50m x 1.8m
25. What is a heated swimming pool?

A. A heated pool is one in which the water temperature is maintained at a particular temperature. The international standard for the temperature of a heated pool is 28 deg C.
26. How much electricity does a filtration plant consume/require?

A. Typically a filtration plant for a 100000 Litre pool will consume not more than 5KW of electricity.
27. What should be the door size of a filter room?

A. The door should be adequate to allow insertion and removal of the filter in the filter plant. For a residential pool keep approximately 1m of clear opening.
28. What slope should I provide at the pool bottom?

A. The slope typically provide in 1" in 20' towards the drain of the pool. Q. How do I decide the number of underwater lights in a swimming pool? A. Typically sizing of lights is done based on 1 300W light per 25 sqm of pool surface area.
29. What are the various types of underwater lights available?

A. Halogen & LED
30. What provisions do I need to make in the pool prior to casting the RCC shell?

A. You need to make provisions for Pool drain Bottom/Wall inlets Vacuum points Underwater Lights
