Maintaining and Servicing a Rental Toilet
Environmental / Water Quality Protection Guidelines
Portable Toilet Management (PTM) activities have the potential to contribute pollutants such as
bacteria, organic matter, disinfectants and suspended solids into our waterways.
Portable Toilet Maintenance
3.1. Storage and Maintenance Facilities
(1) Portable Toilet Maintenance
(a) Maintain all portable toilets in good condition to prevent leaks or spills.
(b) Damaged toilets must be repaired/replaced immediately.
(c) Owner identification and contact information must be effectively displayed in a
prominent location on the exterior of each unit.
3.2 Transportation Management
(2) Waste Transport
(a) Collected portable toilet waste must be disposed of at a permitted wastewater
disposal facility
3.3 On-Site Management
(1) Site Selection
(a) Portable toilets should be located away from high-traffic vehicular areas.
(b) Portable toilets must be placed at least 20 feet away from all storm drains and
streets.
(c) Portable Toilets MUST NOT EVER be sited on top of storm drain inlets or on a street.
(d) Portable toilets shall be placed on a level ground surface that provides unobstructed
access to users and servicing pump trucks.
(e) Portable toilets should wherever possible be located upon natural ground and not on
or within 5 feet of a paved surface such as asphalt, concrete or similar.
(f) If portable toilets must be placed on a paved surface exposed to rainwater or stormwater runoff, extra care must be taken during servicing to ensure any waste water spilled onto the paved surface is rinsed and adequately collected so as not to leave any residue. A wet shop vacuum or similar would provide for adequate collection.
(g) As a minimum, portable toilets should not be located within the 75 foot buffer of any stream or lake, or within any other larger stream/lake buffer that may have been established. With respect to portable toilets used at construction sites, see site plans for details regarding buffers.
(2) Servicing
(a) Portable toilets must be cleaned and have waste removed at least weekly. Additional
servicing and/or portable toilets may be necessary depending on the volume of use
the toilets receive.
(b) Damaged portable toilets must be repaired/replaced immediately.
(c) Rinsing of portable toilets (excluding the inside of portable toilet waste tank) may be
completed on site when the following conditions are met:
(i) Rinse water is controlled to prevent it from entering into a storm drain;
(ii) no more than one (1) gallon of rinse water is used per portable toilet (i.e. low
volume high-pressure cleaners, or bucket and rag. No common household hoses.);
(iii) rinsing is completed at least 20 feet away from a street or storm drain
(iv) Where the portable toilet must be located on a paved surface:
i. any rinse water that comes in contact with the paved surface must be adequately collected.
(v) Where the portable toilet is located on a non-paved surface:
i. rinsing should be completed at least 5 feet away from a paved surface;
ii. rinsing wastewater is drained to the ground at a rate that allows it to immediately soak into the ground;
(d) Rinse water generated during the cleaning of portable toilet waste tanks must not be discharged to the ground or to a storm drain and must be retained within the tank.
(e) In the event of a spill or discharge to a storm drain or waterway, report immediately.
(f) Maintain all portable toilets in good condition to prevent leaks or spills.
(g) Portable toilet wastewater (human waste/sewage) must never be disposed of on-site.
