Many water treatment specialists identify the difference between residential, commercial and industrial applications by the pipe size or tank diameter. While this can often be a convenient shortcut, you’re doing yourself and the industry a disservice. For an average residential water softening application on municipal water, the worst thing that can happen after a malfunction is an inconvenience in the customer’s lifestyle, an increase in cleaning burden, soap usage, water heater scale, heating expense, etc. If the softener in a laundromat fails, the operator could spend significantly more in operating expenses and potentially damage their water heaters, washers and even their water reclamation system. If the softener at a car wash fails, the cars aren’t as clean and RO membranes will fail faster, costing the owner not only more money, but potentially losing them future business from dissatisfied customers. If a softener fails for a critical boiler protection application (even if it is a small residential-size softener), the consequences can be catastrophic and devastatingly expensive. Consequences of failure, therefore, are the real differentiator between residential and commercial/industrial (C/I) applications.

When evaluating a client’s application, be sure to carefully explore the actual consequences of failure, the nature and extent of testing/monitoring required, as well as necessary response times. Have a contingency plan for ensuring a continuous supply of properly treated water for your client.

The commercial and industrial water quality management segment is exciting and filled with many potentially lucrative opportunities. It is satisfying to the ego when you’re able to point out the various manufacturing plants, hotels, casinos, government facilities and other entities that ‘have my water,’ but before entering this segment of our industry, you would be wise to understand a few things.

Commercial and light industrial work can be a natural extension to the scope of work you already perform, but it is very important to comprehend that commercial and industrial systems are not just bigger versions of residential systems and that they require unique knowledge, resources and planning far beyond typical residential work to be truly successful and profitable. Remember, breaking even is not the definition of a successful project. Before tackling any project, you need to learn about the process or application, understand the environment in which you will be working and supplying equipment and properly understand the legal implications of the work that you are considering doing.

Process water quality requirements
Each water-using process has certain specific water quality criteria. Whether you’re simply providing a specific quality of water as specified by the project engineer or acting as a consultant to solve a specific water quality problem, it’s important to understand the actual water quality required and create a reasonable set of expectations for yourself and the client. Consult with the manufacturer of any equipment to be used in the client’s process to ensure you comply with their operational water quality, flow and pressure requirements for best performance as well as warranty validation.

Site survey
Visit the job site, meet with your prospect and observe the potential location of the treatment equipment. This will save you a lot of complications and hassle, while demonstrating that you are truly committed to serving their needs.

Consider the following:

  • How far is this job site from my office (Travel time for installation and service)?
  • What time of day can the installation team have access to the facility?
  • What times of day are convenient to the client (if any) to install a bypass loop?
  • Are there any dimensional constraints to the system (doorways, height, floor space)?
  • Are there any weight limitations (is equipment to sit on a platform or be wall-mounted)?
  • Is there an adequate electrical supply for water treatment equipment?
  • Is there an adequate drain for water treatment equipment?
  • Are there any specific environmental challenges to deal with (temperature, humidity, vibration, seismic issues, intrinsically safe environment)?
  • Are there any specific drainage restrictions for this project (acid/alkaline discharge, discharge salinity, etc.)?
  • Are there any specific legal requirements to meet for this project (increased liability insurance value, HAZMAT, OSHA, MSHA, local licensing, corporate procurement programs, union participation, tribal authority, security clearances, GSA, state purchasing agencies, etc.)?

Don’t be afraid to ask lots of questions; it’s much more intelligent to ask dumb or simple questions now than to wish you had later. Your C/I client has a dramatically different set of expectations than a typical homeowner. Plan for an escalated response to all service issues, as well as a more critical analysis of product water quality. Also plan on stringent monitoring of your output water quality; it has to work properly all day, every day.

Uptime, inventory and incident response requirements
Often overlooked by contractors, uptime and incident response time requirements should be discussed and included in the Scope of Work. Some applications have zero tolerance for downtime and require fully redundant systems to ensure continuous operation. Response time can also impact the viability of a project, as some applications require on-site response within hours of an incident. Coupled with this is evaluating the spare parts inventory that needed to keep in stock to properly support your prospective client. There’s no point in selling a six-inch pipe-size, six-plex softening train if you’re not going to keep replacement valves, actuators and other parts to provide service in a timely manner.

Cashflow (or rather the lack thereof), is typically the single largest hurdle facing small businesses in today’s volatile economic climate. Tackling a $325,000 project with progress payments over the next 12 months might not be appropriate for your business. Be sure to ask detailed questions about how the prospective client is expecting to handle this critical aspect of the project. Don’t be afraid to negotiate terms that you need and be ready to walk away from projects that are not beneficial.

In addition to whatever project-specific insurances are required by the prospective client, understand that adding commercial work to your company’s current scope of work will have a pronounced impact on your general liability, errors and omissions, and Workmen’s Compensation insurance premiums. Talk to your insurance agent about the potential impact on your policy before tackling commercial and industrial projects. Don’t be afraid to turn down work that could jeopardize the financial stability of your company.

Training and oversight
Evaluate the licensing and employee skillset required, as well as whether your water treatment design needs review and approval by a locally licensed engineer. All of this affects your net cost of the project as well as the execution timeline and should not be overlooked or underestimated.

Answer the questions below before attempting a C/I project:

  • What is the actual quality of water needed?
  • What continuous and peak flowrates are needed?
  • What delivery pressure is needed?
  • How many hours of run-time will be required per day/operating cycle?
  • How much water will be used per day/operating cycle?
  • Is any major change (increase/decrease) in water consumption to be expected and when?
  • What drainage facilities are available?
  • What contaminant levels are acceptable to the local authority?
  • What level of redundancy is needed?
  • Does any of the equipment require an ASME stamp?
  • Is an engineer’s stamp required for the equipment and piping design?
  • How soon does the client expect the system to be installed and fully operational?
  • Who will maintain this system?
  • What are the consequences of failure?
  • What payment terms does the client expect?

Water sample analysis
Draw samples of the client’s raw water and have them tested for the organic and inorganic contaminants that will have a negative or complicating effect on the process or interfere with the treatment equipment’s ability to get the job done. I typically recommend the following minimum testing panel:

Hardness as CaCO3  /  Copper  /  Sulfates  /  Total alkalinity  /  Iron  /  Silicates  /  Free chlorine  /  TDS  /  Total chlorine  /  pH
Perform additional tests as needed, especially if the water supply is non-municipal or in an area where the municipal supply quality is known to fluctuate. Armed with an influent water quality analysis, you’re ready to compare the raw water against the process water requirements. Always use appropriate certified testing facilities. Now is not the time to cut corners or be cheap (there’s never a good time or justification for that).

Equipment selection
Work closely with your equipment vendor to ensure that you specify an appropriate solution for this project. Have a frank discussion about who will be liable if incorrect equipment or technology is specified, the extent of that liability and what recourse is available to protect yourself. I often see commercial projects where the previous contractor has undersized the equipment or caused an unacceptable pressure drop in the delivered water. Pay attention to projected functional flowrates and pressure drop through the entire treatment train and use sensible safety margins. Also, look carefully at whether the equipment you’re considering is rated for commercial use; many residential system warranties are void when used in commercial applications, so make sure you understand they warranty impact of the project.

Service and preventative maintenance
While periodic cleaning and disinfection service is important on residential water treatment systems, planned preventative maintenance is critical on commercial and industrial systems. Your equipment manufacturer should have a model preventative maintenance and disinfection schedule for you that can be tailored to the specific project. Discuss this with the client to ensure that the equipment will be properly maintained. Your goal is to prevent or fix problems while they are cheap and easy, with a minimum of operational downtime. If the system includes consumables like acid, caustic, coagulants, flocculants, polymers, chlorine neutralizers, resin cleaners or performance enhancers, be sure to develop a consumables replacement schedule to facilitate easy procurement of consumables by your clients.

Documentation, contracts and purchase orders
Carefully document the expectations of both parties toward a realistic procurement and installation timeline. Carefully review (or have your lawyer do it) all purchase orders and letters of engagement before accepting them to ensure the terms are as originally negotiated and that you understand lien releases, delay penalties, progress payments, two-party checks and other boilerplate commercial contractual clauses that will inevitably be involved.

Installation should be sub-contracted or performed by your in-house installation team to be on time and within the criteria agreed to by the client. This is not household plumbing and will often require the installer to have additional training, licensing and insurance to complete the work. Consult with the appropriate local code enforcement office to make sure the project is compliant with all local codes and that the necessary permits have been acquired.

In addition to following the law, you’d be wise to follow industry best practices by learning from your peers in magazines like this, at trade shows, from the WQA’s Modular Education Program (MEP) and from equipment manufacturers. Treat the client’s facility with respect by being punctual, clean and orderly on the job site. Respect their corporate culture and be sensitive to dress codes, site parking/driving rules and other job-site activities.

System startup and commissioning
While selection, sizing and installation are important, the startup cannot be overlooked. This important step involves systematic filling, rinsing, pressurization, purging and sanitization of the water treatment equipment as well as sanitizing the downstream piping, fixtures and process apparatus. This should be done to prevent contamination that could compromise human health or the client’s workflow. Once the system has been properly commissioned, draw samples of the effluent product water and have them tested by the same testing facility as the original tests for uniformity. Save copies of pre- and post-treatment test data in the project binder to share with your client.

Operator training
Unless you’re planning on having an employee onsite 24/7, you’re going to have to train your client or their employee(s) on operation and maintenance of the water treatment system. This does not take away from your planned periodic maintenance visits, it simply empowers them to keep things running and minimize the need for future emergency service calls. Take the time to train carefully, as many warranty issues are usually caused by operator error, which inevitably stems from inadequate training.

Documentation and drawings
It is common to provide three copies of all operation and maintenance (O&M) manuals to the client. Most clients will also require redline or as-built drawings that document the final installation of the treatment train. For your own purposes, you should carefully document and photograph the installation location and each component in operational condition to simplify troubleshooting and training. Keep serial numbers, part numbers and vendor information on hand in the project file when replacement or repair parts are required.

Realistic expectations are the key to healthy commercial/industrial relations. You don’t need to do everything to be a success in our industry, but whatever you do should be done right. Many dealers have built very profitable and rewarding businesses without venturing outside the residential realm, so don’t feel pressure to embrace the C&I market just because your competitors have. Study and analyze the risks and benefits as well as the impact it will have on your company before you over-commit yourself. There is no shame to gracefully withdraw and defer to a more knowledgeable/experienced colleague if you become uncomfortable during the initial discovery process. Put your customer first, seek excellence and keep learning.
