Find cooling tower cleaning and water-treatment accounts

What makes a cooling tower site a qualified account?

A qualified account has confirmed equipment, a responsible operator, work your crew can perform and a purchasing path you can follow. Start with those four gates. A large tower outside your response territory, an inaccessible roof or an agreement with no upcoming review date can consume estimating time without producing a workable proposal.

Write a target statement before collecting addresses. For example: existing evaporative tower systems within 45-minute normal drive of the shop, with an authorized facilities contact and planned access for cleaning. Test it against traffic, dispatch coverage and the response you intend to sell.

Separate your offers. Physical cleaning, chemical treatment service, mechanical maintenance and water management consulting need different information and responsibilities. Record which tasks your team performs and which require an agreed specialist. An introduction can begin with a paid scope survey when the owner cannot provide enough information for a firm annual price.

Use the commissioning and tower-types guides linked below for the technical background. This workflow takes the next step: deciding which plants deserve a call, which need a survey and which are ready for estimating. Keep that decision tied to evidence someone else can check.

Which facilities should you put on the first list?

Start with facility types where a tower is plausible, then confirm the actual plant. CDC's identification guidance names larger buildings such as hospitals, hotels, schools and offices, along with industrial processes and data centers. Its guidance concerns public-health investigations; using those building categories for territory research is an Anvilfield planning method. None of the categories proves that a specific property has a tower. [1]

Choose facilities whose access and purchasing arrangements fit your operation. The table supplies questions for an initial call, not claims about every facility in that category. A smaller plant with a clear shutdown window may fit your crew better than a large campus with an unconfirmed outage plan.

How do you find towers without inventing a service need?

Build the list from several evidence channels. Search public tower records where available, mechanical permits, owner capital plans and agency solicitations. Review dated roof and yard imagery, then compare the candidate with equipment records or an authorized site observation. CDC identifies imagery, ground scouting and permitting or registration records as complementary tower-location methods, with visibility and record-completeness limitations. [1]

For each sighting, preserve the address, marked equipment location, original reference and image capture date. Keep the review date separate. If a screen or shadow hides the equipment, write unresolved. If the capture date is unavailable, write unknown. Several circular fan openings are an observation; the classification and equipment count still need confirmation.

Deduplicate at the plant level. One campus can have several street addresses, and multiple buildings may appear to connect to one plant. Retain the building relationships but do not count each address as a separate customer. Use a stable site identifier, then attach equipment and circuit identifiers as records become available.

For public opportunities, search the agency's own portal for cooling tower cleaning, condenser-water treatment, chiller-plant maintenance and water management services. Read the current solicitation, attachments and addenda. Record the deadline, site-walk requirements and purchasing contact exactly as published. A past award is research on contract scope and purchasing history; confirm future procurement timing with the agency.

No image moves a candidate into a contamination or compliance category. Keep those fields outside the aerial review. The purpose of the list is to identify whom to contact and what to verify.

Account qualification worksheet

Keep one account record that estimating and dispatch can both use. Every uncertain entry needs a named next check. Unknown chemical consumption is a request for records, not permission to fill in a convenient allowance and describe it as verified.

The sample entries below describe a typical site, CT-018. They demonstrate how the record changes as evidence arrives. Preserve the earlier observation when updating the confirmed fields.

Who buys cleaning and who controls water treatment?

Ask the facilities contact to identify the equipment operator, purchasing authority, cleaning contractor, treatment provider and water management program lead. Check whether one person fills several roles. Record the roles separately and verify purchase authorization after matching the property owner.

Use a specific opening: We service tower cleaning and water-treatment work in this area. Who manages that scope, and when do you next review the agreement? Once connected, ask whether the buyer wants cleaning only, treatment support or a coordinated package. Request permission for the records review and site visit before scheduling either.

CDC describes a water management program, or WMP, as an ongoing process with a team, system description, control measures, monitoring, responses and documentation. Build your service responsibilities around the actual site's program. A contractor's visit report is one input to that program; identify who reviews results and acts between visits. [3]

If an incumbent handles chemistry and the owner only wants cleaning, arrange the handoff before pricing. Identify who approves the procedure, who supplies treatment chemicals, who confirms return to service and who receives the completion record. Give each deliverable one responsible party and a named recipient.

What must you verify on the first site visit?

Confirm equipment identity and the water circuits first. Count sites, tower cells and separately treated systems in different fields. Check whether two cells share one treatment system or two nearby units have separate circuits. The piping diagram and operator walkdown settle the count that belongs in the proposal.

A closed-circuit tower still has an external spray-water circuit during evaporative operation. Baltimore Aircoil's operating explanation separates that circuit from the process fluid inside the coil. Ask which circuit the proposed work covers, then confirm the installed arrangement. Do not infer that a closed process loop removes the spray-water service scope. [2]

Walk the access route with the operator. Record entry and escort arrangements, working platforms, material movement, available utilities and the proposed waste-handling route. Identify the equipment that needs isolation and the person who can authorize an outage. A survey does not authorize opening guards, operating valves or changing chemical feed.

Request cleaning history, treatment reports, available water-use records and the current program. Photograph the equipment tags and agreed scope boundaries where permitted. Describe observed deposits or damaged components plainly and refer them for the appropriate technical assessment. Keep laboratory interpretation and corrective actions with the responsible program team.

Before leaving, state what remains unresolved. If access equipment, isolation or disposal cannot be confirmed, give the buyer a conditional scope or price the further survey. Those unknowns affect the work too much to hide inside a small contingency.

How do you set the cleaning and monitoring schedule?

Set the schedule from the actual WMP, equipment instructions, operating conditions and applicable requirements. CDC recommends offline cleaning and disinfection at least annually and says maintenance frequency depends on tower design, cooling load and local environmental conditions. Treat that as CDC guidance, not a universal legal interval or proof that one cleaning satisfies every site. [4]

Build separate calendar lines for cleaning, contractor treatment visits, operator monitoring, sampling and program review. A monthly contractor visit allowance does not establish how often the operator must check the system. Write who handles each task, the applicable procedure and the action when a reading falls outside the site's limits.

For laboratory work, confirm the sampling plan, method, sample locations, reporting units and result recipients before requesting a quote. CDC distinguishes routine testing from investigation testing and cautions that Legionella results alone do not measure health risk or predict disease. Do not sell a single sample as a safety certificate. [5]

Where local registration, testing or reporting rules apply, obtain the current official requirement and record its jurisdiction, effective date and responsible party. This guide supplies no national registration rule or universal sampling frequency. An active investigation or emergency response needs its own authorized scope and coordination with the relevant public-health authority. [3, 4, 5]

Scope and responsibility table

Write the proposal so the operator can see what happens, when it happens and who completes the handoff. Use measured quantities where available. Mark provisional quantities as allowances with a reconciliation rule rather than describing an unlimited service.

Water-use records can improve the estimate. DOE recommends tracking makeup and blowdown quantities, conductivity and treatment performance, with the treatment specialist setting appropriate operating targets. Request those records before promising chemical or water savings. The prospecting worksheet does not justify changing a conductivity setpoint. [6]

Worked annual account example

Sample site CT-018 has two verified cells on one shared water system and operates year-round. For this exercise, the site program and applicable requirements have already been reviewed and the listed contractor tasks are sufficient for the proposed package.

The case uses two planned cleaning events, each using two qualified technicians for eight paid hours apiece, including travel, setup, isolation coordination, cleaning, treatment coordination and closeout. That is 32 technician-hours annually. The case uses twelve separate treatment visits by one qualified technician at three paid hours each, including travel, onsite tasks and reporting: another 36 hours. Add eight office hours for annual account administration and program-review support. No visit or hour is counted in two lines.

Anvilfield research uses a direct labor cost of $65 per technician-hour and office labor costs $55 per hour, both including wages and payroll burden but excluding vehicle expense, company overhead and profit. Allow $1,600 for annual chemicals across the cleaning and treatment tasks, $600 for equipment and consumables, and $400 for waste handling. The case uses four laboratory submissions at $125 each, including bottles, shipping and analysis. Their collection time is already inside treatment-visit hours; the budget covers four submissions.

The case uses fourteen site mobilizations, each totaling 40 vehicle miles, at $0.80 per mile for fuel, wear and vehicle costs only. Cleaning crews share one vehicle. The case uses normal working hours, safe existing access, no lift or crane, no confined-space entry, no overtime, parking fees, tolls, lodging, permits or subcontractor charges. The owner supplies utilities, escorts and an authorized isolation process without a contractor charge. Consumable allowances include modeled purchase taxes; no separate sales tax is modeled on the service invoice.

The owner retains and funds all assigned between-visit monitoring and response duties. Major repairs, extra sampling, emergency disinfection, replacement parts and changed conditions require a separately authorized scope. Any different requirement means revising this estimate before offering the price.

What does that account need to earn?

The target gross margin is 35 percent on the $8,408 direct cost. Price equals cost divided by one minus the margin: $8,408 / 0.65 = $12,935.38. Round the proposed annual price to $12,960, or twelve invoices of $1,080 if the buyer accepts equal billing. Billing frequency does not change the service schedule.

At that rounded price, gross profit is $4,552 and gross margin is about 35.1 percent. The case uses a separate $2,000 allocation for company overhead, including insurance, office expense and selling costs not already charged above. The remainder is $2,552 before income tax. The example includes no financing cost, bad debt or additional acquisition campaign expense.

Now test a scope miss. Each cleaning event needs four additional paid hours per technician at the same labor rate, with no other cost change. Sixteen added technician-hours cost $1,040. Direct cost becomes $9,448 and gross profit at the original price falls to $3,512, about 27.1 percent. Price needs to reach $14,535.38 to retain the modeled 35 percent margin.

That is why the survey must settle access and cleaning limits. Reconcile chemical, laboratory and waste allowances against the agreed quantities, and state how changes receive approval. A larger visible tower count does not repair an estimate that leaves a full crew's extra day unpaid.

How do you move from a candidate list to a proposal?

Use evidence-based stages: candidate located, equipment confirmed, responsible contact confirmed, need and timing confirmed, survey authorized, scope reviewed, proposal issued and agreement accepted. These are suggested workflow labels. Set the completion evidence beside each stage so different people do not use qualified to mean different things.

For a small pilot, choose twenty candidates inside one practical route. Record how many are confirmed evaporative systems, how many contacts identify the buyer, and how many owners authorize a survey. Leave the counts blank until the work occurs. Do not borrow a conversion percentage from the worked service-price example; it covers one defined account and models no sales funnel.

Follow up with the agreed next action. If the owner needs a cleaning budget, send the missing-scope questions. If renewal is later, record the buyer-confirmed review date. If another provider handles treatment, establish whether the buyer wants coordinated cleaning or a separately procured service. Close out unsuitable sites with the reason so the next salesperson does not repeat the same research.

What to document

Keep the source reference, observation date, confirmation date, equipment tags, circuit boundaries, contact roles, operating calendar and scope version together. Attach the survey notes, owner-provided records and written inputs. Retain the purchasing deadline or renewal evidence independently of the equipment evidence.

A weak note says two towers, needs cleaning. A useful note says two cells confirmed against tags CT-1A and CT-1B; operator reports one shared circuit; cleaning proposal requested; isolation procedure and waste route pending owner approval. The second note tells estimating what it can use and what it still needs.

Carry the same identifiers into the service agreement and first work order. Record exclusions, allowances, owner duties and the person authorized to approve extra work. The first crew should be able to locate the right equipment and understand the promised deliverable without reconstructing the sales conversation.

Common mistakes

• Treating a tower sighting as proof that cleaning is overdue. Confirm the current program and owner-requested scope.
• Counting fans, cells and independently treated systems as the same quantity. Verify each count separately.
• Calling a recorded owner the buyer without confirming operating and purchasing responsibility.
• Offering unlimited chemicals, sampling or emergency response inside a fixed fee supported by narrow allowances.
• Using contractor visit frequency as the owner's monitoring schedule.
• Calling a laboratory result a safety certificate or using imagery to assign compliance status.
• Pricing the cleaning before checking the route for personnel, equipment and waste.

Field checklist

Build the next tower inventory

Once the qualification worksheet works on a small local list, define the next search area and the visible asset you want reviewed. Specify how to handle screened equipment, uncertain image dates and multiple addresses around one plant. Keep unresolved candidates available for a targeted records check.

PorchRocket's Asset Search offers custom searches and monitoring of assets visible from above. Use the cooling-tower destination to request a search scope for your territory. Ask for the evidence and review fields your team needs, then verify the operator, circuit arrangement and service requirements before estimating. The useful output is a list with a clear next check for each candidate. [7]

Standards and references

Sources reviewed November 4, 2026 cover equipment distinctions, identification, water management, testing, and water-use records. CDC's identification page displays an October 19, 2026 update.

The linked guidance does not determine the adopted requirements at a particular address. Obtain the current local rules, actual equipment instructions, contract specification and site program before finalizing work. No chemical dose, universal sampling schedule, contamination finding or guaranteed savings is established here.

Use the related Anvilfield guides for tower construction, commissioning, chiller-plant coordination, waterside economizer operation and cooling-equipment identification. Keep the prospect record linked to that technical work as the scope becomes specific.

Units and terms

Count labor in paid person-hours, vehicle travel in total miles and service events by the work actually performed. Keep those quantities separate from cells and treatment systems. Gross margin is gross profit divided by revenue; markup is selling price minus cost, divided by cost. At the example price, markup is $4,552 / $8,408, about 54.1 percent; gross margin is $4,552 / $12,960, about 35.1 percent. Use the margin formula above when margin is the pricing target. [8]

Methodology

Counts, prices, work rates, schedules and outcomes in typical cases are inputs to the Anvilfield research model. Calculations use the stated scope, formulas, cost inclusions and exclusions. Cited public records and technical documents support their attributed facts. Named case records, dates and outcomes are scenario inputs; cited public records retain their source attribution. The account worksheet uses scenario entries rather than observed property records or a market-size estimate.
