Installation & Use of a Chemical Toilet Disposal Point

Introduction

When you’re running a caravan park, campsite, glamping site or any facility where portable chemical toilets (often branded “Elsan” units) are used, having a reliable Chemical Toilet Disposal Point (CTDP) is an essential piece of infrastructure.

Product Overview

Here is an outline of what the units offer:

  • They use GRP material (fibreglass) for the body, with stainless steel fixings durable, chemical resistant.
  • They are available in versions with built-in flush and without flush (i.e., tipping point only).
  • They meet relevant water-company byelaws (for example, incorporating a Type AUK1 Air Gap).
  • Dimensions:
  • They can be placed directly over a manhole or plumbed via a 110 mm sewer drain connector.
  • The units can be sited either indoor or outdoor.

Why choose a GRP unit from GRP Mouldings?

  • Durability: GRP/fibreglass is robust and chemically resistant, which is vital when dealing with chemical toilet waste.
  • Proven compliance: The units are already approved/used by utilities like Bristol Water & Scottish Water (for flushing models)
  • Customisable: Though standard colours are green, other colours may be made (for a small extra charge).

Installing a Chemical Toilet Disposal Point

Here’s a step-by-step of how you might install such a unit:

  1. Site selection: Choose a flat, accessible hard-standing area adjacent to the caravan/camping WC block or service area. Consider user flow (people emptying chemical cassettes) and maintenance access.
  2. Prepare base and drainage:
  3. Install the unit:
  4. Ventilation/air gap compliance: Ensure the installation meets required air-gap standards (e.g., Type AUK1 air gap) to prevent backflow
  5. Commissioning and signage:
  6. Maintenance planning:

Key Considerations & Best Practices

  • Usage volume: If the facility has heavy traffic (many caravans/glamping units), select the version (flush vs non-flush) according to throughput. Flush units offer better cleanliness but are more complex.
  • Material compatibility: Ensure the chemicals in the portable toilets are compatible with the disposal unit material — GRP is good, but always confirm.
  • Environmental compliance: Make sure the disposal point is connected in accordance with local wastewater regulations; water companies often require specific air gaps and prevent direct connection of chemical waste without proper treatment.
  • Access and signage: Ensure sufficient space for users to approach, handle the cassette safely, pour into the unit, and that signage is visible.
  • User hygiene: Provide wash-down facilities and clear instructions for users to rinse the cassette and hands after disposing. This improves user experience and reduces maintenance issues.
  • Colour and aesthetics: The unit will likely be visible on site; we offer standard green but other colours are possible — match to site branding or surroundings if desired.
  • Winter use: If outdoors, consider frost protection for water supply (flush version) and ensure the unit remains usable in low temperatures (prevent freezing, ensure lids seal properly).
  • Budget and long-term cost: While the upfront cost of GRP units may be higher than a simpler concrete or plastic tank, long-term durability, ease of cleaning, and reduced maintenance make it worthwhile.

Why This Matters for Caravan & Camping Sites

For sites offering chemical toilets (for example in mobile units, motorhomes, caravans, glamping pods), having a dedicated disposal point is essential for user convenience and hygiene. It sends a message of professionalism and care for environmental compliance.

The right solution reduces risks: improper disposal can lead to blockages, contamination, regulatory fines, user complaints and odour problems. By investing in a quality GRP unit from a specialist like GRP Mouldings, you are ticking many of the boxes.

Conclusion

If you operate a site where chemical toilet users need a reliable disposal point, the units provide a robust, well-specified solution built from GRP/fibreglass with compliance in mind. From selecting flush vs non-flush, choosing the right location, ensuring proper plumbing, and maintaining the unit, following the considerations above will help you provide an easy to use, hygienic facility for your users.
