- How often should we be cleaning / inspecting our water tanks?
The AWWA recommends inspection of drinking water tanks at least every 3 years. Frequency of water tank cleaning is dependent on your sediment accumulation and the requirements of your regulatory agencies. (AWWA M42)
- What are the benefits of using divers to clean and inspect water tanks?
Compared to traditional draining operations, in-service work provides you with many advantages. These include minimal water loss, sustained fire protection capacity, and no interruptions in your normal procedures or operations. Indeed, in most cases, access is the only thing you'll need to provide. For an expanded list contact us and we'll be glad to get the information to you.
- How does LEC's in-service water tank maintenance operation compare in price?
Our clients routinely tell us that our services save them not only money, but also time (another precious commodity if you have numerous job responsibilities like most of our clients). Our methods prevent unnecessarily wasting finished water and allow for a “face to face” view of the interior tank surfaces. Contact us and we can provide you with a quote.
- Is diving in water tanks sanctioned by my regulatory agency?
LEC is in complete compliance with every state's regulatory agency and exceeds every national standard and regulation. LEC is in constant contact with all state agencies, and is an on-going resource for local, regional, and national regulatory commissions.
- Does in-service water tank cleaning create turbidity problems?
NO. LEC has worked with State and Federal regulatory agencies, most notably AWWARF, researching the benefits of cleaning water storage tanks in-service. In every single test there was no significant turbidity created during the cleaning and inspection process. In each case water quality parameters actually improved upon completion of LEC cleaning the water tank. For additional information on AWWARF Case Study #20 contact our staff at 1-800-438-2187
- Can I still keep my wells, tanks and plant in operation during diving operations?
Yes, diving is an approved method for inspection and cleaning of water storage tanks while they remain on line and in-service. That was the original reason for starting this revolutionary process. We have since added a huge list of other reasons to utilize LEC’s expertise and technology. We would be glad to provide them - contact us.
- Will your divers contaminate my drinking water?
No. Our professional dive technicians are completely encapsulated during the entire process. At no time is there any contact with the water column. Further, everything entering your tank (cleaning and testing equipment, divers and recording apparatus) is dedicated to potable water and is completely disinfected before every introduction into the water. Again, every test done has demonstrated an improvement in water quality due to the LEC Advantage.
- Can you fix water tanks in-service?
Most routine preventative maintenance tasks can be performed while the tank is in-service and online. Some examples of water tank repairs that can be performed are: Leak Detection, Leak repairs, Gate/Slide Valve replacement, Coating repairs and Crack repairs. For additional information on a particular repair contact us.
