Lakeside venues, canal-side settings, riverside gardens, and waterfront locations are among the most sought-after event spaces in the UK. The views are stunning, the atmosphere is unique, and the photographs are unforgettable.

The toilet provision, however, requires more careful planning than at most venues. Proximity to water introduces environmental obligations, access challenges, and placement constraints that landlocked sites do not face.

Why Waterside Events Need Special Attention

Environmental Protection

Any toilet provision near a body of water must prevent contamination. Under the Environmental Permitting Regulations 2016 and the Water Resources Act 1991, discharging polluting matter into controlled waters is a criminal offence. Even an accidental spillage from a toilet unit that reaches a lake, river, or canal can result in prosecution, fines, and serious environmental damage.

Ground Conditions

Waterside sites tend to have:

  • High water tables — the ground is waterlogged beneath the surface
  • Soft, marshy areas near the water's edge
  • Clay or silt soil that becomes extremely slippery when wet
  • Flood risk — water levels can rise rapidly after heavy rain

Access Constraints

Waterside venues are often accessed by narrow lanes, towpaths, or footpaths that may not be suitable for heavy delivery vehicles.

Aesthetic Sensitivity

Lakeside and waterside venues are chosen for their beauty. The toilet provision must not compromise the visual appeal of the setting.

Environmental Requirements

Minimum Distance from Water

Position all toilet units at least 50 metres from the water's edge. This provides a buffer zone that reduces the risk of contamination in the event of a spillage or leak.

If 50 metres is not achievable due to the venue layout, discuss the situation with the hire provider and, if necessary, with the Environment Agency. Additional containment measures (bunding, drip trays) may be required.

Containment

  • Ensure all units are on stable, level ground where the risk of toppling is minimal
  • Use drip trays or bunding beneath units where the ground slopes towards water
  • Check waste tanks for leaks before the event
  • Brief servicing crews on the proximity to water and the need for extra care during waste removal

Waste Disposal

All waste must be collected by a registered waste carrier and disposed of at a permitted facility. At waterside sites:

  • Confirm that the servicing route does not cross the water's edge or flood-prone areas
  • Ensure that servicing vehicles do not park so close to the water that spillage could reach it
  • Complete waste transfer notes for every collection

Types of Unit

Chemical Portable Toilets

The most common choice. Self-contained with no external waste discharge. The sealed waste tank is emptied by the servicing vehicle.

Compost Toilets

A good option for environmentally sensitive waterside locations. They produce no liquid waste, use no chemicals, and align with the conservation values of many waterside venues.

Luxury Toilet Trailers

Suitable for weddings and formal events at lakeside venues, provided:

  • The access route can accommodate the trailer and towing vehicle
  • The placement area is firm and level (not soft waterside ground)
  • Power and water can be supplied (generator and bowser if mains are not available)
  • The trailer is positioned at a safe distance from the water

Accessible Units

Essential at any public event. At waterside venues, position the accessible unit on the firmest ground with the most accessible approach — away from slopes, soft ground, and uneven terrain near the water.

Placement

Firm Ground Is Essential

Waterside venues often have a gradient from firm ground to soft, wet ground near the water. Always position toilets on the firm ground, even if this means they are further from the event area.

  • Test the ground firmness by walking on it — if your feet sink, the ground is not suitable
  • Use boards or trackway under units on marginal ground
  • Avoid areas that flood after rain — check with the venue or landowner for historical flood levels

Away from the Water

  • Minimum 50m from the water's edge
  • Uphill of the water, not downhill — so that any spillage drains away from, not towards, the water
  • Away from boat launching points, jetties, and fishing platforms

Screened from the View

The view is the whole point of a waterside venue. Screen the toilet area from the main event space and from the water's edge:

  • Use existing vegetation, walls, or buildings
  • Temporary screening with fencing, fabric, or planting
  • Position behind a natural rise in the ground if one exists

Access

Delivery Vehicle Access

Lakeside and waterside venues are often at the end of narrow lanes or accessed by towpaths. Before booking:

  • Drive or walk the access route and measure any pinch points
  • Check overhead clearance (low bridges, trees, power lines)
  • Assess the road surface — unmade tracks may not support heavy vehicles
  • Identify a turning area for the delivery vehicle
  • Discuss access constraints with the hire provider — they may have smaller delivery vehicles available

Servicing Vehicle Access

The servicing vehicle (vacuum tanker) may be different from the delivery vehicle. Confirm:

  • The servicing vehicle can reach the units
  • The servicing route does not damage the venue's grounds
  • The vehicle can operate safely near water

---

Flood Risk

Some waterside venues are in flood risk areas. Check:

  • The Environment Agency flood risk map for the venue postcode
  • Historical flood data from the venue or landowner
  • Weather forecasts in the days before the event
  • Whether the venue has a flood warning system

If there is a risk of flooding:

  • Position units on the highest ground available
  • Have a contingency plan for relocating units at short notice
  • Brief the hire provider on the flood risk so they can advise on suitable unit types
  • Consider cancellation or postponement if a flood warning is issued

Specific Venue Types

Lakeside Weddings

  • Luxury toilet trailers positioned on firm ground, screened by planting
  • Festoon lighting on the path from the reception to the trailer
  • Extra matting on the approach — lakeside ground can be dewy and slippery, even in summer
  • Accessible unit on the most level ground with a clear, firm path

Canal-Side Events

  • Canal towpaths are typically narrow — delivery may need to be from the road side, not the towpath
  • Boats and narrowboats moored nearby may have occupants — position units with regard to their privacy
  • The Canal and River Trust may have specific requirements for events on their land

Riverside Events

  • River levels can change rapidly after rain. Monitor levels in the days before the event.
  • Position units well back from the riverbank
  • Ensure the approach path does not cross any flood-prone areas

Reservoir and Mere-Side Events

  • Water company land may have specific requirements for events near reservoirs
  • Discuss toilet provision with the water company as part of the event approval process
  • Compost toilets may be preferred in environmentally sensitive catchment areas

Servicing

Pre-Event

Full service on delivery. Check all units for leaks — particularly important at waterside sites.

During the Event

  • Single-day events: mid-event check and restock
  • Multi-day events: daily professional servicing
  • Monitor waste tank levels — do not allow tanks to reach capacity, as this increases the risk of spillage during servicing

After the Event

  • All waste removed by registered waste carrier
  • Waste transfer notes completed
  • Site inspected for any spillage or ground damage
  • Ground protection removed and ground reinstated

---

Costs

Costs for waterside events are similar to other outdoor events, with potential additional charges for:

  • Difficult access (smaller delivery vehicles, manual handling)
  • Additional ground protection (trackway, matting, boards)
  • Extended servicing routes

| Item | Typical Cost |

|------|-------------|

| Luxury toilet trailer (weekend) | £500-1,500 |

| Standard portable toilet (weekend) | £60-120 |

| Accessible unit (weekend) | £80-150 |

| Ground protection | £50-300 |

| Generator (if needed) | £100-250 |
