Stored Fuel Maintenance

Is your stored diesel fuel ready for an emergency?

If you fail to maintain your stored fuel and storage tanks, it could be a disaster waiting to happen. 

A hospital relies on the continuity of its electricity supply – patients on life support cannot survive without the electricity supply to power life support machines. Hospital standby power provided by back-up generators must activate within a timeframe of ten seconds and hospitals must have a sufficient quantity of stored fuel on site to keep back-up generators running for up to four days to cover for an extended power outage.

Because modern fuel contains lower sulphur content and significantly higher amounts of biodiesel, bacterial and fungal growth are common in stored fuel. Microbial contamination, known as the diesel bug, is a problem that faces every hospital storing fuel. 

Contaminated fuel supplies can result in at best machinery not operating efficiently and at worst in total breakdown. Failure to regularly inspect your stored fuel and storage tanks can result in emergency, mission-critical equipment failing when you need it most.


A cost-effective solution for hospitals across the UK

Andel provides a comprehensive range of oil storage maintenance services including:

Pollution prevention and compliance

Andel has been carrying out oil storage compliance inspections for over 25 years for customers in the public and private sectors. Andel can ensure that robust pollution prevention measures are in place and your hospital’s fuel storage is fully compliant with regulatory requirements.

Andel inspections are carried out by OFTEC registered and fully qualified technicians and can provide a full detailed report for all of a hospital’s on-site fuel storage. 

Andel’s annual oil storage compliance inspections go beyond standard OFTEC recommendations to give you total peace of mind that your oil storage remains compliant with all current regulations. 

Pollution prevention products

Andel offers a range of innovative pollution prevention products including bunds, pumps, separators, gauges, generator exhaust abatement systems and alarm systems for any size of hospital fuel oil storage installation.


Drainage and Interceptor Maintenance

Andel provides drainage services to some of the largest public and private sector organisations in the UK 

Andel has become a recognised market-leader in the maintenance of surface water drainage systems and underground interceptor waste tanks and separators.

Drainage maintenance is vital to the care delivery at any hospital

Because of the high numbers of patients, visitors and staff at any hospital, there is always an increased risk of blocked drains caused by items wrongly or accidently being flushed down toilets or entering wastewater systems. If drains and sewers become seriously blocked, wastewater can back up into the hospital, causing major disruption and adversely affecting patient care and in some cases leading to ward closures.

Many hospital buildings around the country have ageing drainage systems that are becoming increasingly susceptible to blockage, damage and deterioration. 

Prevention is better than cure

Andel recommends planned and preventative drainage maintenance. We provide a range of drainage services:

  • Site surveys
  • Drain water sampling
  • Drain tracing
  • Drain mapping
  • Drain clearing
  • CCTV drainage surveys
  • Underground leak detection
  • Drainage remedial work

Interceptor maintenance and pollution prevention

Pollution poses a significant legal, environmental and financial risk to any hospital with a hard standing area. Any areas that catch rainfall and have significant vehicle traffic or fuelling facilities must have an oil separator installed to avoid surface water drainage polluting the environment. Many hospitals have large hard standing areas that require ongoing monitoring and maintenance.

Andel provides interceptor installation and regular servicing and support to hospitals throughout the UK.

You can rest assured that with Andel you will have the products, expertise and services to maintain your interceptor waste tanks and drainage systems and keep you protected from the risk of environmental incidents and the potentially costly consequences. We provide a highly cost-effective service tailored to suit the need.

Interceptor emptying service

If an interceptor needs emptying, we use de-watering tankers that only take away contaminants and not grey water. Unlike some other operators, Andel’s tankers are equipped to extract the contents of the tank on site, separate the water from the oil, silt and any other impurities and return the grey water to the tank.

Because we are not carrying grey water around in our tankers, we are able to cover several sites in one day, offering a lower cost to customers. We also avoid the costly and time-inefficient exercise of refilling the interceptor tank from the mains water supply, saving hospitals time and money as well as reducing the environmental impact.

Leak Detection

A complete turnkey solution for any hospital’s leak detection requirements

Andel’s award-winning, BMS-compatible Floodline® hybrid leak detection systems set the benchmark for reliability, durability and value for money, providing an effective solution for any leak detection requirements within any hospital environment. 

Our extensive Floodline® product range includes water and oil leak detection cables, sensors and alarms, gas leak sensors that can be calibrated to detect any commercially used gas and temperature and humidity sensors for environmentally sensitive areas – all connecting to a single, state-of-the-art, BMS-compatible, hybrid control panel for continuous environmental monitoring. The system can also automatically isolate water, oil and gas supply in the event of a leak.

Andel’s Floodline® is a zonal system, providing continuous monitoring, that can pinpoint a leak from single to multi-zone and distance measuring systems, with the capability to protect any size hospital, both old and new.

Andel provides a complete solution – from consultancy and site survey to equipment selection, system design, supply, installation and after-sales support and maintenance for any size of project for hospitals anywhere in the UK.
