The issues Every city, county, and state has waste water of many types generated by different activities of its residents. What most people don’t realize is all areas, rural or urban have basically two types of waste water systems, sanitary sewer, and storm water. These two systems are distinct and different. The sewer system handles all waste water generated from sinks, toilets, showers etc.. The storm system is constructed to handle waste water generated from weather only. The main difference between the two systems being this; sewer water is treated and cleaned, storm water is not. Here in lies the problem. When washing is done in a parking lot or any outside area the runoff if not contained enters the storm system and therefore is discharged to a body of water, ponding basing, etc. without being treated or cleaned at all.
The rules and the Reality Mobile washing and water runoff is governed by a variety of agencies depending upon your location. Generally speaking the driving force and the origination all regulations is the federal government. More directly, the Environmental Protection Agency, (EPA). Specifically, in 1987 The Clean Water Act required the EPA to issue permits for storm water discharge. In each state this permit is administrated by a state agency. In California, for example, the State Water Board elected to adopt a permit covering the whole of California. In effect, every entity, either, public or private is covered under this general permit and is required to comply with it. The goals of the permit process were to eliminate non-rain discharges to the storm system that may occur as a result of activities such as truck washing, the cleaning of forklifts, containers, loading docks, etc. Secondly, it sought to eliminate pollutants, (chemicals, spoiled product, and other substances) that may be exposed to rain water and washed down the storm system. In effect the permit process eliminated the lawful discharge of anything other than uncontaminated rainwater into any storm system. In reality, therefore, to comply with this permit within the state of California all wash water from the washing of trucks and other equipment must be diverted from storm drains, recovered and disposed of into the sanitary sewer system. Secondly areas used for the washing of such equipment must be washed clean and that water diverted and recovered as well.
Our Methods Valley Fleet Clean has been at the for-front of addressing the need for environmentally safe and legal mobile washing. Much time and experience has gone into helping our customers maintain compliance with local state and federal environmental regulations. Our proven environmentally safe wash program consist of four elements
Site Plan—Before any washing is even begun, we will visit and physically inspect the wash site, noting water flow characteristics, storm water entry points and legal disposal areas (if any). At completion of this inspection you will receive and have an opportunity to review a written site recovery plan specifying the exact methods and procedures to be implemented.
Diversion, or drain protection—This can be accomplished in a number of different ways, depending upon the type and number of water entry points the wash area has. We have numerous type and style of drain plugs as well as artificial damming mechanisms.
Collection—This is achieved by “vacuuming” pooled water into one of our collection trailers.
Disposal—This can be legally be done in two ways. On-site sanitary sewer disposal or transport to a Valley Fleet Clean site for permitted discharge.
- It is important to note that recovered wash water, when the correct chemicals and processes are used, is well within legal limits for unprocessed disposal to a sanitary sewer.
