Environmental and Specialist Services


Maintenance & Water Treatment

Operating to SPATA’s and PWTAG’s requirements, JSA offers a specialist water treatment and maintenance service, including spring opening, winter shutdown and one-off swimming pool cleaning as well as spa, hot tub, steam room & sauna maintenance.


Environmental Solutions

Increasing concern about environmental impact and the need to conserve energy are important drivers for today’s businesses. Exciting developments are taking place in all areas of pool and spa design, ranging from increasingly efficient and environmental heating systems to more effective accessories like underwater lighting.

Our approach is to ensure we pass on new trends and opportunities to customers, from the most efficient heating solutions – heat pump or solar power technology – to reducing energy costs by using LED pool lights. Energy efficiency and environment are built in to our design approach: we use efficient control systems that minimise energy consumption for all installations. Wherever possible, we offer swimming pool pipework and shell insulation for outdoor pools and are exploring the use of sustainable resources such as geo-thermal heat pumps. Our experts can discuss your specific sustainability or energy efficiency policy with you, making recommendations and seeking solutions to your particular issues.


Environmental Systems

We specialise in heat recovery and air handling systems for indoor pools of all types and can install gas, electrical or oil-fired systems for both indoor and outdoor pools. Since the filtration of water, its treatment and the air handling systems are complementary and require design to suit each individual pool installation, we source all equipment from known and leading manufacturers in the UK and Europe.

The complete systems include all waterflow pipework from pool/spa to plantroom. Air handling units are specifically designed for each project. Water treatment plant is specifically ultra violet for primary and high precision free chlorine/PH for secondary disinfection. Control systems are designed and manufactured on a bespoke basis for each installation and can incorporate switching for underwater lighting and air temperature/ filter pump set back if pool covers are used.


Servicing Appliances and Filters

Appliances like boilers should be serviced on an annual basis to avoid breakdowns or the premature and potentially costly replacement of parts. We will repair and service gas and oil boilers, heat pumps, de-humidifiers, air-handling units and other components as part of our service. Our fully-qualified engineers are GASSAFE or NICEIC registered and experienced in working on all types of equipment including, Certikin, Hayward, Teledyne Laars and Purex oil and gas heaters as well as air handling units such as Calorex, Climatec and Heatstar range of equipment and de-humidifiers such as Vaporex. We recommend sand changes for pool and spa filters at least every 5 years to maintain the required water quality. We also use glass & Zeoclere media to give enhanced water clarity.


Filter Media Replacement

We recommend changing the sand in pool filters every five years. While filters may function after as much as 10 years unchanged, they will not be operating at full efficiency. Filter sand has been ground to a size of .45 to .55 mm in diameter and is very rough when new. This roughness is what makes the sand efficient at filtering out the particles of dirt in your water. As this roughness is smoothed out – as stones in a stream wear smooth over time – your filter’s efficiency goes down. This means that your system has to run more frequently to accomplish the same task. This can increase the amount of sanitizer used, thereby increasing your chemical costs. In addition we have found that after five years, your sand has worn enough to allow dirt to penetrate so deep that normal backwashing doesn’t clean it completely. The result is a shorter filter cycle which requires more frequent backwashing and high chemical use.
