Remedial Works

Many companies can identify problems but cannot resolve them without employing sub-contractors. Eaton Environmental Services Ltd has developed the ability to perform much of the remedial work identified when a water system survey is carried out. This has the benefit of not tying up site maintenance staff for long periods, or having to employ several different companies to carry out the remedial work.

Examples of remedial work we can carry out:

Bringing Tanks up to Comply with Water Regulations

The Water Regulations 1999 require that cold water storage tanks comply with certain specifications, e.g. be well insulated, have tight fitting lids, have screened overflows and vents, have a good throughput and turnover of water – and so on. We can carry out this work and combine it with cleaning and disinfection work at the same time so the tank does not have to be out of service twice.

Fitting Shunt Pumps to Calorifiers

The Approved Code of Practice L8 and HSG 274 recommends that the water in the base of a hot water calorifier is heated to 60°C for an hour each day to minimise the growth of Legionella bacteria in the bottom of the calorifier. This can be difficult to achieve without connecting the flow pipework to the base of the calorifier and fitting a shunt pump to push the hot water around the calorifier.

Replacing Tanks and Calorifiers

Sometimes it is more cost effective to replace a corroded tank or a scaled calorifier than to try and effect repairs, which may only be temporary anyway.

Altering Pipework

The ability of deadlegs and blind ends (capped off pipes) to harbour and encourage the proliferation of Legionella is becoming much more high profile, and the way some tanks are installed can produce inherent stagnation. We can engineer out these problem areas for you.

Installing Pre-Treatment Equipment

Fitting a water softener or electronic scale conditioner to the supply to a hot water heater or calorifier will not only significantly reduce the risk from Legionella “hideout” in scale deposits, but will save a huge amount in energy costs – a serious consideration these days. Read more

Continuous Disinfection

Sometimes the bacteriological problem cannot be engineered out, or the client may want a “belt and braces” approach on sensitive systems, and this is where continuous disinfection comes in. A disinfecting chemical is dosed proportionally to the water supplying the system to ensure a completely safe operation. Read more
