Rainwater Harvesting Systems

Alton Facility Services: Rainwater Harvesting Systems

Imagine reducing your property's reliance on mains water by up to 50% while embracing eco-conscious living. With Alton Facility Services' rainwater harvesting pump systems, it's possible. This practical guide explores the seamless installation process of a complete system using market-leading equipment, expertly fitted by our trusted team across Hampshire, Surrey, and West Sussex.

Strategic Placement of Rainwater Tanks

Efficiency begins with smart placement. We recommend installing your rainwater harvesting tank between 2 to 10 metres from your property, allowing for minimal pipework and easy access. Our systems can be placed beneath patios, driveways, or green spaces using reinforced tank designs that support load-bearing surfaces without disrupting aesthetics.

Preparing the Excavation

Our engineers carry out precision excavation in accordance with groundwater levels, slopes, and local geology. All groundwork is completed to exact tank dimensions, ensuring proper burial and alignment. With minimal disruption, we clear obstacles like roots and debris before beginning installation.

Installing the Tank

Thanks to the lightweight yet durable design of our tanks, installation is quick and doesn't require heavy machinery. We ensure each unit is level, aligned, and fitted with secure inlet/outlet ports for long-term performance and maintenance access. Turrets are installed with sealed gaskets to prevent leaks.

Filter Systems & Pipework Connection

Next, our team installs a high-efficiency filter package that captures leaves, debris, and contaminants before water enters the tank. Roof downpipes are then securely connected, directing flow through the filter system into storage. We also fit an overflow u-bend with a 1% fall to control excess water and mitigate flood risk.

Backfilling & System Stabilisation

We use non-concrete backfill materials such as gravel for faster drainage and environmental sustainability. Backfill is added in 30cm compacted layers alongside gradual filling of the tank with water, ensuring equalised pressure and structural integrity.

Dome Shaft Access

Our systems include a flush-fit dome shaft for surface-level access to the tank for inspection and servicing. This discreet yet functional feature ensures your landscaping remains uninterrupted.

Connecting the Pump System

We offer both submersible rainwater harvesting pumps and wall-mounted booster pumps, depending on your property layout and usage needs. The selected pump is connected to the home via a dedicated feed pipe, with all power and control systems neatly installed in your plant room or garage. Our systems support use for irrigation, toilet flushing, washing machines, and external cleaning.

Compliance and Pipe Marking

All non-potable water lines are clearly marked in black and green in line with UK water regulations, ensuring separation from drinking water systems and safeguarding user health.
