Rainwater harvesting is a practical and increasingly popular way for households in Wandsworth and surrounding SW London areas to reduce mains water use, lower bills and support sustainability goals. Scrub A Dub Clean can advise on various rainwater harvesting systems ranging from simple water-butts with diverters to more advanced above-ground tank systems suitable for larger gardens. We focus on solutions that integrate with existing gutter systems while maintaining effective drainage and complying with UK guidance on safe installation.

Our process begins with a site assessment to calculate roof catchment area, expected rainfall capture, and suitable storage capacity for your needs. For many gardens a single well-placed water butt with a high-quality diverter offers an excellent balance of cost, simplicity and functionality. For larger-scale needs we can advise on multiple water-butt configurations or liaise with specialist installers for buried tanks and pump systems. We always ensure diverters include a bypass for heavy storms so that drains remain unobstructed and overflow risk is controlled.
