Wash Bays & Recycling
There are many factors that determine what type of wash bay you should install, and which interceptor you should use. The Environment Agencies Guidelines set out guidance notes for the provision of wash bays, and we're able to assist clients and end users with the advice you need to comply.
We're able to clarify and explain in simple terms what you need to do, and how your wash bay should be constructed. We'll advise the methods you can use to contain the water and dispose via silt traps, sumps or interceptors etc, and how and where it should drain to.
Many clients would like to explore the opportunity to re-use or recycle water, and we're able to provide site specific advice where a suitable drain is not available.
During our meeting we'd need to know what are you proposing to wash or are washing now; e.g. cars, plant, boats, trains, lorries or vans etc? We'd probably need you to provide a list of all vehicles on the fleet that you proposed to be washed including their type, size etc, along with the quantities of each to be washed over a given period.
Some of this info can be carried out desk to desk, where we would require info such as what type of washing, understanding if it is all external or top washing only or whether the client will be washing chassis and engines. We'd also need to know if the wash or proposed hot or cold water jet wash will be a manual operation or an automated drive through system.
We'd then look how many of each are washed in given period, the frequency or pattern of washing, and whether the wash frequency is throughout the day or all in one short period of time.
When you have given us a brief description of the service you're providing, for example cleaning a private fleet, MOT washing, steam cleaning the clients own fleet, valeting etc, and if the system to be used by allocated person or via the public, we'd then look at how many washes of the above per day or per week, if the fleet is varied and if applicable, what are you using to wash the above with now?
We can also advise with regards to which detergents you are or you will be using, along with looking at what other chemical or detergent products will be used on or around the wash bay that could contaminate the water, what products are likely to be washed off the vehicles, and whether the vehicles are carrying or coated with any product that may contaminate the water.
If there are high levels of oils and greases that are likely to be washed off, or the process include washing of joints or other items that are greased, we'd also be able to specify an oil removal system to ensure you don't contaminate the drains.
Our experience enables us to easily identify any issues with an existing wash bay, including its size, the suitability of an existing wash sump or collection point, the sizes or cubic metres of any existing wash bay tanks, or the compliance of an existing wash sump or collection point.
The consulting takes into account many types of wash bays including wash bays that are surrounded by a kerb, covered with a roof, open, outdoors or indoors, and we'll advise where any contaminated water from the wash bay or proposed location should outflow to, and the correct use of an interceptor prior to disposal.
All water recycle units have to be built to order and the spec is determined by the level and frequency of washing. This means that it is almost impossible to offer guide prices over the phone as we have to spec the reclaim on the information you provide.
The spec is based on the number of cars you are washing and therefore how much water is being used within a given period. We would need information from you to provide this accurate info for us to base the reclaim on.
There are really 2 basic types of water reclaim and we'll be able to offer you guidance with regards both types, which one to chose and budgetary costs to install.
A re-use system filters the water to the standard required to be used in the pumps or pressure washers, and can be used for the initial pre-wash. However because it is re-used water it is not a good enough standard for rinsing and so clean town water (tap water) would have to be available for rinsing the vehicles afterwards. Basic re-use systems are less expensive but the disadvantage is that there is extra water falling onto the wash pad due to both the extra rinsing and rain water.
A full reclaim both filters the water, and removes all detergents and suspended solids, leaving the water fully recycled and suitable for spot-free rinsing. There is no need to use town water to rinse the vehicles because the standard of water is very high and they are generally purpose built.
The project cost will depend on whether you have a plant room and existing interceptor, vehicle numbers and frequencies, and the type of drainage outflow. All reclaims have to be housed in a frost free secure environment such as a plant room, and the supplier would need all services bringing to the reclaim plus builders works to connect pipe work to the interceptor.
A reclaim of either type simply will generally not operate without a suitable interceptor, which must be reclaim compatible, and if the wash bay is not covered we would have to accommodate any extra water due to rinsing or rain water falling onto the wash pad.
