Water Feature and Pond Construction

Water feature and pond construction involves excavation, liner installation, pumps, and electrical connections.
Drowning risk is present once the feature is filled — even shallow ornamental ponds pose risks to children.
Excavations for ponds and lakes require assessment for trench collapse, especially in soft or wet ground.
Electrical installations for pumps and lighting in or near water require RCD protection and IP-rated equipment.
BS 7671 Section 702 covers the specific electrical requirements for swimming pools and water features.
Liner installation involves working in excavations with slippery surfaces and limited escape routes.
Mechanical equipment including pumps, filtration systems, and UV units require safe installation access.
Working near water features during and after construction requires appropriate fall protection measures.
Stone and rockwork placement around features involves manual handling of heavy, irregular-shaped materials.
Completed water features in public spaces must comply with safety design standards to prevent drowning.

Prevent drowning	Even shallow ponds pose drowning risks during construction and once filled — barriers and edge protection are essential.
Electrical safety	Pumps and lighting in water create electrocution risk if not installed to BS 7671 Section 702 standards.
Excavation safety	Pond excavations in wet, soft ground are prone to collapse without adequate support or battering.

Do

Don't

Assess excavation stability and use battering or support in soft or waterlogged ground
Ensure all electrical installations comply with BS 7671 Section 702 for water features
Use RCD-protected supplies and IP-rated equipment for all pumps and lighting near water
Install temporary edge protection around pond excavations during the construction phase
Use team lifts or mechanical aids for placing heavy rockwork and stone around features
Wear appropriate footwear with slip-resistant soles when working on liner surfaces
Test electrical installations fully before filling the feature with water
Design public water features with safety measures to prevent child drowning incidents
Brief all workers on the emergency procedure if someone falls into the excavation or water
Fence or barrier the completed feature until permanent safety measures are installed

DON'T leave pond excavations open and unguarded where children or the public can access
DON'T install electrical equipment in or near water without IP-rated protection and RCDs
DON'T work in pond excavations without checking ground stability and escape routes
DON'T manually lift heavy rockwork alone — use mechanical aids or team lifting methods
DON'T fill the feature with water before all electrical testing is complete and signed off
DON'T leave pumps running and accessible where people could contact moving parts
DON'T walk on liner surfaces without slip-resistant footwear — liners are extremely slippery
DON'T connect pumps or lighting to non-RCD-protected electrical supplies near water
DON'T design public features without considering drowning prevention for young children
DON'T assume shallow water is safe — even 30cm of water can drown a small child
