Natural Swimming Pools are great for all the family and are environmentally friendly, with lower maintenance and running costs than a conventional pool. Please read the questions in this FAQ blog to understand the ins and outs of building a natural swimming pool and Clear Water Revival.

Where do we work?

Our head office is in Bristol; however we are not limited to working in the local area and actively undertake projects across the United Kingdom.

How does the water stay clean?

The ClearSpring filter starves algae of the nutrients it needs to survive. Chemical systems kill bacteria, we stop it growing in the first place. 

Are there any chemicals?

We do not use any chemicals, just pure water.

Are the pools hygienic?

A clean aerobic environment is maintained in all corners of a Clear Water Revival pool.

Pathogens which can cause illness are controlled by the filter’s ‘beneficial’ bacteria – a permanent means of protection. In contrast, the risk of infection in a traditional, chemically controlled pool is vulnerable to any failure to maintain the dosage of disinfectant. Avoiding the use of chlorine also reduces the risk of irritation of the eyes and or skin.

Why does my natural swimming pool have algae?

This could mean one of three things – a) suspended algae turning the water green, b) filamentous algae (slimy string like blanket weed), or c) unicellular algae on surfaces (brown or green) as part of the ‘biofilm’ that forms on surfaces within a natural swimming pool.

A) Our water is always clear unless the pump fails, which rarely happens;

B) Filamentous algae never appear in a healthy, well designed adequately maintained natural swimming pool

C) In type 3, 4 and 5 pools some brown algae may slowly develop within the biofilm (over several weeks and if there is zero maintenance) but this can be prevented with the use of an automatic cleaning robot and pool cover. Where an automatic robot is not being used a clean / level surface will have to be brushed off from time to time.

What happens to my pool in the winter?

Winter, Spring, Summer or Autumn… your natural swimming pool or pond is guaranteed to gleam all year round.

Can my pool be heated?

Yes, any of our natural swimming pool types can be covered and heated up to 28 degrees and any system can be used. Type 4 and 5 pools generally require less heating due to their colour (darker linings), and the shallower water zones encourage passive solar gain.

Note: Some swimming pond systems cannot be heated. This DOES NOT apply to our technology and systems.

Is the swimming pool separate to the planted area?

Yes, the swimming zone is separated from the water plants by submerged walls.

Can I have a natural swimming pool without plants?

Our ClearSpring filter requires no planted zones giving you far more design flexibility.

Does my pool have to be a specific shape?

Any design; modern and sleek or naturalistic. Since no plants are needed in our system, you can design your pool in any style that fits your taste. As a result, many of our clients opt for a highly modern, sleek look, however, for those who prefer a more naturalistic aesthetic, plants can be added for visual effect. 

Are there are design restrictions?

No. Any design is possible within our five systems. As a result, each system does have some general restrictions e.g. the colour of liner and location in relation to trees and sunlight. Check out our pool gallery for some design inspiration.

Can I have a natural swimming pool indoors?

Indoor or outdoor: Our ClearSpring™ system is the only chemical free filtration option for indoor pools on the market.

Can you build a natural swimming pool in my basement?

Yes! Clear Water Revival were the first natural pool company to build an indoor swimming pool using our state-of-the-art technology and since then we have completed a number of stunning natural indoor projects across the UK including basement pools.

If you want to avoid using chlorine in your basement swimming pool project and prevent the associated chemical odors from taking over your home, the ClearSpring system is the answer. We are the only company capable of creating a naturally filtered basement swimming pool.

Could I have a stream diversion for my natural pool project?

This is not an option for our pools, which are ‘closed’ systems. The use of a steam would make it an ‘open’ system.

How much maintenance is involved?

The beauty of natural swimming pools and ponds is that they require a fraction of the maintenance compared to conventional pools, as there are no chemicals to add.

In Pool types 4 & 5 pools very little maintenance is required – although it is recommended that once a month the floor of the pool is hoovered free of sediments and the shallows are cleaned twice a year. The level of maintenance in Pool types 1- 3 depends upon the use of automatic cleaners and pool covers.

Are there any cost implications?

New build costs are in line with conventional bespoke pools. Conversion costs are kept down if the original pool is a solid concrete structure.

Pool types 1 and 2 require more maintenance and cleaning. Costs can therefore be slightly more than in pool types 3 and 5 No major water exchange is required.

There is no cost saving in having an existing pond there, but it is possible to convert.

Do I need planning permission to build a swimming pool?

Generally speaking, private outdoor pools do not require planning permission. However, it is essential that you check with your local authority planning department if planning approval is needed. For example, you may need planning approval if your pool will affect nearby buildings or drains. You should also consult the planning authority if your property is listed or in a conservation area. 

How long can I expect my pool to last?

If built by a reputable natural swimming pool business and then properly maintained, a swimming pool should last you a lifetime.

How do the running costs compare?

Building a natural swimming pool or pond is a very complex process that should be carried out by a trained builder. We have found that the difficulty of construction is often underestimated, especially when compared to conventional pools, so it is best left to the professionals.

Can I build a natural swimming pool or pond on my own?

Lower water turnover rates mean that our system saves you money over time as energy usage is reduced. Moreover, energy costs are less than a quarter of a traditional pool because the pumps utilised are a lot smaller. Also, ongoing running costs are considerably less compared to a conventional pool without the need for chlorine.

How long does it take to build a natural swimming pool or pond?

Timescale depends on many factors, for example, the type, size and location of the pool and in particular whether the pool is part of a wider property refurbishment. In order to get an understanding of a potential time frame for your existing natural swimming pool project, please contact us today.

How much does building a natural swimming pool cost?

The cost of a project depends on factors such as construction, pool finish, size, type, design, features and finish and site conditions including ground, drainage, access and location.
