For same-day additions, call us directly for fastest service. Additional units will be priced at our standard rates and can typically be delivered within 2-4 hours. For multi-day events or long-term rentals, we recommend assessing needs early to ensure availability. There's no penalty for adding units, and we're happy to adjust your rental to meet your needs.

For short-term rentals (1-3 days), porta potties are thoroughly cleaned and sanitized before delivery. For weekly rentals, we provide service once per week. For long-term construction site rentals (monthly), standard service is once per week. Each service includes: waste tank pumping and disposal, interior cleaning and disinfecting, restocking toilet paper and hand sanitizer, deodorizer application, and general inspection. More frequent servicing can be arranged for high-use situations or specific requirements at an additional cost.

Extra servicing typically costs $75-$125 per unit per service. For large events, we can also provide on-site attendants who maintain cleanliness throughout the event. Contact us to arrange additional servicing or discuss your specific needs.

We follow strict cleaning and sanitation standards including: EPA guidelines for waste disposal, OSHA health and safety requirements, CDC sanitation recommendations, and industry best practices from PSAI (Portable Sanitation Association International). All units are cleaned with EPA-registered disinfectants effective against bacteria, viruses, and pathogens. Before each rental, units undergo comprehensive cleaning and inspection. Our service technicians are trained in proper sanitation procedures and waste handling. We maintain detailed service logs for accountability and quality assurance.

We dispose of all porta potty waste according to strict EPA regulations at licensed waste treatment facilities. The process includes: (1) Pumping waste into enclosed tank trucks, (2) Transport to EPA-approved treatment facilities, (3) Processing at wastewater treatment plants where waste is properly treated, (4) Documentation and compliance tracking. We never dispose of waste improperly or in unauthorized locations. All our waste hauling equipment and procedures meet federal and state environmental regulations. We maintain proper licensing and permits for waste handling and disposal.

Yes! We offer on-site restroom attendant services for large events, festivals, and occasions requiring continuous maintenance. Attendants perform: regular cleaning throughout the event, restocking supplies as needed, monitoring for issues, ensuring proper function, maintaining cleanliness standards, and providing immediate response to problems. Attendant services are typically recommended for events with 500+ attendees, multi-day festivals, VIP areas, or any high-profile event where restroom presentation is critical. Pricing varies based on event duration and number of attendants needed.

FlushJohn serves all types of events including: weddings and receptions, corporate events and parties, festivals and fairs, concerts and music events, sporting events and tournaments, graduation parties, birthday parties, family reunions, church events, school functions, park gatherings, farmers markets, food truck events, marathons and races, outdoor markets, and any outdoor gathering requiring sanitation facilities. We have experience with events ranging from intimate gatherings of 25 people to large festivals with thousands of attendees.

For weddings, we recommend our deluxe flushing porta potties or luxury restroom trailers. Deluxe units ($150-$250/day) offer flushing toilets, hand washing sinks, mirrors, and lighting - providing a more refined experience for your guests. Luxury restroom trailers ($800-$1500/day) offer the ultimate experience with multiple stalls, climate control, premium finishes, and a true bathroom feel. For a 150-person wedding reception (4-5 hours with alcohol), we typically recommend 2-3 deluxe units or 1 luxury trailer. The units can be positioned discreetly and we offer delivery/pickup outside of event hours.

Yes! We specialize in corporate event porta potty rentals. For corporate functions, we typically recommend deluxe units or luxury trailers to maintain a professional image. Our services for corporate events include: flexible scheduling around business hours, discreet placement and professional appearance, priority service and reliability, itemized invoicing for accounting, and dedicated support. We serve company picnics, grand openings, outdoor team building events, parking lot sales, client appreciation events, and corporate festivals. We understand the importance of presentation and reliability for corporate clients.

Festival porta potty quantities depend on attendance, duration, and amenities. General guidelines: for festivals under 4 hours, provide 1 unit per 50-75 attendees. For all-day events (8+ hours), provide 1 unit per 35-50 attendees. If alcohol is served, increase by 25%. Always include ADA compliant units (minimum 10% of total, at least 1 unit). For a 1000-person one-day festival with alcohol, we'd recommend 25-30 standard units plus 3 ADA units, along with hand washing stations. We also recommend on-site attendants for festivals and can provide servicing mid-event if needed. Multi-day festivals require daily servicing.

Yes, public events typically have specific requirements: (1) ADA compliance - federal law requires wheelchair accessible units (typically 10% of total, minimum 1), (2) Local permits - many municipalities require permits for temporary restroom facilities, (3) Health department regulations - some jurisdictions have specific sanitation requirements, (4) Hand washing stations - especially important for events with food service, (5) Minimum quantity standards - based on expected attendance, (6) Servicing schedules for multi-day events. We're experienced with public event requirements and can help ensure compliance. Permit acquisition is typically the event organizer's responsibility, but we provide necessary documentation.

For events involving food service, health codes typically require hand washing stations in addition to porta potties. Requirements usually include: porta potties for general use, separate hand washing stations with soap and paper towels, proper signage, and adequate quantity based on vendor count and public attendance. For food vendors, OSHA and health departments often mandate hand washing facilities within 200 feet of food preparation areas. We recommend at least one hand washing station ($75-$125/day) for every food service area, plus standard porta potties for attendees. Always check local health department requirements for your specific event.

OSHA regulations require construction sites to provide adequate sanitation facilities. Specific requirements: 1 toilet for every 20 workers or fewer, facilities must be available within 200 feet of work areas, hand washing facilities must be provided, toilets must be maintained in sanitary condition with regular cleaning, toilet paper must be provided, and facilities must be available at the start of each workday. For projects lasting more than 30 days, we recommend our construction packages ($150-$200/month) which include weekly servicing. Violations of OSHA sanitation standards can result in significant fines.

OSHA Standard 1926.51 mandates: (1) One toilet seat and one urinal per 40 workers OR one toilet seat per 20 workers, (2) Facilities must be available within 200 feet of work areas where practical, (3) Hand washing facilities must be provided (soap and single-use towels), (4) Facilities must be maintained in sanitary condition with weekly service minimum, (5) Toilet paper must be provided, (6) Facilities must be available at the start of each shift, (7) Facilities must meet ADA requirements where applicable. Non-compliance can result in OSHA citations ranging from $7,000 to $140,000+ depending on severity. We ensure all our construction units meet OSHA standards.

OSHA requires 1 toilet for every 20 workers. Examples: 1-20 workers = 1 porta potty, 21-40 workers = 2 porta potties, 41-60 workers = 3 porta potties, etc. This is the minimum legal requirement. We often recommend adding extra capacity for convenience and to maintain sanitary conditions between weekly services. For projects with multiple shifts, count the peak worker presence. Always include hand washing stations for OSHA compliance. For sites with 50+ workers, consider adding ADA compliant units even if not legally required.

Construction porta potty rentals can be arranged for any duration: weekly ($35-$50/week per unit), monthly ($150-$200/month per unit), or for the entire project duration (discounted long-term rates). Most construction rentals are month-to-month with flexible extension options. There's no maximum rental period - we've supported projects lasting several years. Long-term rentals (3+ months) may qualify for discounted rates. The rental continues until you notify us that the project is complete and schedule pickup. Monthly rentals include weekly servicing.

Our construction porta potties can be secured using several methods: (1) Weight - units are heavy (180-280 lbs) and stable in normal conditions, (2) Staking - units can be staked into ground for added stability, (3) Tie-downs - units have tie-down points for securing with straps or cables, (4) Concrete blocks - can be placed around base for extra stability, (5) Fencing - units can be placed within fenced areas for security. For sites with high wind exposure or vandalism concerns, we recommend additional securing methods. Units can also be locked after hours if needed. We'll assess your site and recommend appropriate security measures.

The Americans with Disabilities Act (ADA) requires accessible restroom facilities for: all public events and gatherings, construction sites (when workers with disabilities are present), government-funded projects, commercial properties open to the public, and any event or facility covered by Title II or Title III of the ADA. General guidelines: public events should have at least 5% accessible units (minimum 1), construction sites should have at least 1 ADA unit per site. ADA units must meet specific requirements: minimum 60"x60" interior space, grab bars, accessible door width, proper ramp, and accessible fixtures. Non-compliance can result in legal penalties and discrimination claims.

OSHA regulations governing portable sanitation include: Standard 1926.51 (construction sanitation), Standard 1910.141 (general sanitation), and related health standards. Key requirements: adequate toilet facilities based on worker count, facilities within 200 feet of work areas, hand washing facilities with soap and towels, sanitary maintenance and weekly cleaning, toilet paper provision, facilities available at shift start, proper waste disposal, and accessibility for workers with disabilities. OSHA can conduct inspections and issue citations for non-compliance. Penalties range from $7,000-$140,000+ depending on violation severity. All our units meet OSHA standards.

Health department regulations vary by state and locality but typically include: minimum sanitation standards, cleaning and maintenance frequency, waste disposal requirements, hand washing facilities for food service events, proper ventilation, adequate toilet paper and supplies, vector control (flies, odors), and proper signage. For events with food service, health departments often require permits and inspections. We follow CDC sanitation guidelines, use EPA-registered disinfectants, and maintain compliance with local health codes. Our service procedures exceed most health department minimum requirements. We can provide documentation of our sanitation practices for permit applications.

We strictly comply with all environmental regulations including: EPA waste disposal standards - all waste disposed at licensed treatment facilities, proper waste transport in approved vehicles, no discharge to storm drains or ground, use of biodegradable and environmentally-safe chemicals, prevention of groundwater contamination, compliance with Clean Water Act, proper licensing and permitting for waste hauling, and documentation of disposal. Our units contain waste in sealed tanks preventing environmental contamination. All waste is treated at wastewater treatment plants before release. We maintain required permits and follow state environmental agency guidelines.

Permit requirements vary by location. You may need permits for: large public events (city/county event permits), street or sidewalk placement (right-of-way permits), extended construction projects (building department permits), food service events (health department permits), park or public property use (parks department permits). Small private events on private property typically don't require permits. We recommend checking with your local city/county offices early in planning. We can provide specifications, insurance certificates, and documentation needed for permit applications. Permit acquisition is typically the customer's responsibility, but we're happy to assist with information.

For proper porta potty placement, you need: (1) Level ground - units must sit level for proper function, (2) Firm surface - concrete, asphalt, compacted gravel, or firm grass (avoid mud or soft ground), (3) Vehicle access - delivery truck needs access within 50 feet, (4) Clearance - 12 feet vertical clearance for delivery truck and boom, (5) No overhead obstacles - no power lines, tree branches, or structures in path, (6) Adequate space - minimum 4'x4' footprint per unit plus door swing space, (7) Away from food areas - recommended 50+ feet from food service or preparation, (8) Accessible to users - consider pedestrian paths and lighting. We'll help assess your site before delivery.

Porta potties should be placed on relatively level, firm ground. Minor unevenness (1-2 inches) can usually be accommodated with leveling boards or pads. For significantly uneven terrain, we may need to use wooden platforms or leveling systems. Soft ground (mud, sand, loose dirt) can cause units to sink or become unstable. Solutions for soft ground: place plywood sheets under units for distribution of weight, use ground protection mats, wait for ground to dry if possible, or select alternate placement location. For construction sites with poor ground conditions, discuss terrain challenges when booking so we can plan appropriate solutions.

Best practices for porta potty placement: (1) Accessibility - convenient location within 200 feet of main activity areas, (2) Privacy - somewhat secluded but not isolated for safety, (3) Lighting - near lighting for evening events if possible, (4) Level ground - stable, firm surface, (5) Away from food - minimum 50 feet from food preparation or service areas, (6) Grouped together - place multiple units together for efficiency, (7) ADA access - accessible units on accessible paths, (8) Away from property lines - respect neighboring properties, (9) Easy delivery access - truck can reach within 50 feet. For construction sites, place centrally to work areas. We can provide placement recommendations based on your site layout.

Yes! We can deliver porta potties to multiple locations within our service area. This is common for: large events with multiple activity areas, construction projects with multiple work zones, company locations across a city, or events spanning large areas. Delivery to multiple sites within the same service area typically doesn't incur extra fees if coordinated on the same delivery day. For widely separated locations (different cities), scheduling and pricing is handled separately for each location. Let us know your multi-site needs when requesting a quote, and we'll coordinate efficient delivery logistics.

The number of porta potties needed depends on: (1) Attendance - the number of people expected, (2) Event duration - longer events need more units, (3) Alcohol service - increases restroom usage by 30-40%, (4) Event type - concerts and festivals have higher usage than corporate events. General guidelines: For events under 4 hours without alcohol: 1 unit per 50 people. For events under 4 hours with alcohol: 1 unit per 35-40 people. For all-day events (8+ hours): 1 unit per 35 people. Always include at least 1 ADA compliant unit. For construction sites: 1 unit per 20 workers (OSHA requirement). Contact us for personalized recommendations based on your specific event.

For wedding porta potty quantities, consider: (1) Guest count, (2) Reception duration, (3) Alcohol service. Recommendations: 50 guests / 4 hours / with bar = 2 units, 100 guests / 4-5 hours / with bar = 2-3 units, 150 guests / 5 hours / with bar = 3-4 units, 200 guests / 5+ hours / with bar = 4-5 units. We recommend deluxe or luxury units for weddings rather than standard units. It's better to have extra capacity than too few units. Consider separate units for ceremony vs. reception if locations are far apart. Plan for women's higher usage (60-70% of restroom usage typically). Include 1 ADA unit for accessibility.
