About Rainwater Tank Installation in Mitchells Plain

Rainwater harvesting is one of the smartest investments a homeowner in Mitchells Plain can make. With rising municipal water tariffs and recurring drought concerns across South Africa, a properly installed rainwater system reduces your water bill, provides backup supply during restrictions, and makes use of a free resource that literally falls from the sky.

Abacas Solution designs and installs complete rainwater harvesting systems in Mitchells Plain, from compact garden tank setups to large multi-tank systems that supply toilets, washing machines, and irrigation. We handle every component: tank selection and placement, guttering connections with leaf guards, first-flush diverters that discard the initial dirty runoff, filtration for collected water, pump installation with pressure control, and plumbing connections to your home.

We work with all major South African tank brands including JoJo, Nel, and Roto. Tank sizes range from 1,000 litres for basic garden watering up to 10,000+ litres for whole-house supplementation. For properties wanting to use rainwater for toilets and laundry, we install separate rainwater plumbing lines with clearly marked pipes as required by SANS 10252 to prevent cross-contamination with the municipal supply. Every system includes a backflow preventer and all necessary compliance measures.

This is one of several specialist services we offer under specialist plumbing in Mitchells Plain. As part of our Mitchells Plain plumbing team, we bring over 25 years of hands-on experience to every job.

A backflow prevention device must be installed if the rainwater system connects to any point that also receives municipal water. Tanks must be placed on a stable, level base capable of supporting the full weight. Electrical pump connections must comply with SANS 10142.

Frequently Asked Questions

What size rainwater tank do I need for my home in Mitchells Plain?

Tank size depends on your roof area, local rainfall patterns, and how you plan to use the water. For garden irrigation in Mitchells Plain, a 2,500-5,000L tank is usually sufficient. If you want to supply toilets and laundry as well, 5,000-10,000L is recommended. We calculate the optimal size based on your roof catchment area and typical rainfall data for Mitchells Plain to ensure you get the best return on investment.

Can rainwater be plumbed to my toilets and washing machine?

Yes, we regularly plumb rainwater to toilets and cold-water laundry connections. This is where the biggest savings come from, as toilets account for roughly 30% of household water use. SANS 10252 requires that rainwater plumbing is on separate, clearly marked pipes with backflow prevention to ensure it never mixes with your municipal drinking water supply. We handle all the compliance requirements.

Do I need a pump for my rainwater tank in Mitchells Plain?

If you are only using gravity feed for garden watering from a tap at the bottom of the tank, a pump is not strictly necessary. However, for any pressurised use like toilets, washing machines, or sprinkler irrigation, you need a pump. We install automatic pressure pumps that start when you open a tap and stop when you close it, just like your normal water supply.

What maintenance does a rainwater system need?

Maintenance is minimal but important. Clean gutters and leaf guards every 3-6 months, empty the first-flush diverter after heavy rains, replace or clean filters annually, and check the pump pressure switch yearly. We provide a simple maintenance guide at installation and can schedule annual service visits if you prefer us to handle it for your Mitchells Plain property.
