Portable Toilet Mistakes to Avoid for Lansdale Events

Mandy Leary • November 10, 2026

Portable toilets seem simple, but planning mistakes can leave guests waiting and crews without facilities. This article explains the most common mistakes event planners make with portable toilets in Lansdale, PA, and how to avoid them.

Underestimating the Number of Units

The most common mistake is ordering too few units. Event planners often guess the crowd size and forget that people arrive in waves. A line forms when the number of units does not match the peak hour, not the total attendance.


Plan for the busiest period of the event. Consider the start time of the main activity, the length of the program, and whether food or drinks are served. Those details shape how often guests will need a restroom.


Why Peak Hours Matter More Than Total Guests

A crowd of one hundred people may spread out over a full day. The same crowd may arrive within one hour for a food truck or a game. Planners who count only total attendance often run short during that rush.

First Steps to Take Right Away

A homeowner can take a few safe steps before a provider arrives. These steps reduce the load on the system and keep people away from the problem.


  1.  Stop using water. Avoid running dishwashers, washing machines, and showers until the problem is checked.
  2. Avoid flushing toilets and draining sinks. Every use adds more wastewater to a system that is already stressed.
  3. Keep people and pets away from the affected area, including the yard above the tank and drain field.
  4. Note when the problem started and what you saw, such as the fixture affected, odors, or wet spots.
  5. Call a licensed septic provider and describe the symptoms.


These steps do not repair the system. They protect the household and give the technician better information.

Forgetting Accessible Units

Accessible units are often overlooked until the day of the event. An event open to the public should include at least one unit that meets accessibility needs. Guests who use wheelchairs or other mobility aids need a unit with enough space and proper access.



Mention accessibility when you request a quote. The rental team can plan placement so that the accessible unit sits on a firm, level surface with a clear path from the parking area. Accessible portable toilets should also be checked for clear space inside the unit before the event starts. Ask the team to confirm the layout so the entrance and turning space suit the guests who will use it.

Not Planning Delivery Access

A delivery truck needs room to reach the placement site. Planners sometimes choose a spot in a field, behind a tent, or down a narrow lane, and the truck cannot get through on the day of the event. That delay can push back placement and leave the units late.


Walk the site with the route in mind. Note gates, low branches, soft ground, and tight turns. Share those details with the rental team before the portable toilets arrive on delivery day.


Common Access Problems in the Lansdale Area

Lansdale is a borough in Montgomery County, and its event sites range from park lots to community centers and business areas. Traffic on nearby corridors, including the Route 309 area, can affect the timing of a delivery. Planning around peak traffic times can help the driver arrive on schedule.

Placing Units on Uneven Ground

A unit that sits on slanted or soft ground can tip, leak, or feel unsafe. Planners often place units on grass that looks level but is soft after rain. A firm, level surface protects users and keeps the unit stable through the event.



Ask the rental team which surfaces work best for placement. Avoid areas where water collects or where the ground slopes toward a path.

Forgetting Restroom Supplies and Maintenance

Some event planners assume the units will stay stocked for the whole event. A busy day can use up supplies quickly, especially hand sanitizer and paper. Confirm with the rental team who restocks the portable toilets and how often.



Plan for a maintenance visit during long events. A quick check keeps the units clean and reduces complaints during peak hours.

A Simple Checklist Before Your Event

Use this short checklist before you finalize an order:


  1.  Estimate the number of units based on peak hour, not total attendance.
  2. Match the rental length to the full event schedule, including setup and teardown.
  3. Request at least one accessible unit for any public event.
  4. Walk the placement site and note any delivery access problems.
  5. Choose a firm, level surface away from water and slopes.
  6. Confirm who restocks and cleans the units during the event.

Avoiding these mistakes makes a big difference on event day. A clear plan for the number of units, the rental length, accessibility, and delivery keeps guests comfortable and the schedule on track.
