1. Where would the Greywater System be installed?

A grey water system is typically installed underground with a gravity feed alowing grey water to pass through the filter into the chamber. Aquarista would therefore install the grey water pump chamber at a point where even the lowest (usually the shower) of the pipes from the bathrooms and laundry can reach to system.  We manifold these pipes to get the grey water to a central location, achieving a fall of between 1 in 40 and 1 in 60.

2. Can the greywater piping be concealed within the walls?

If you are building a new house, then these pipes are easily concealed. Your plumber simply brings all sources of greywater to the position best suited. As far as a retro-fit is concerned, most of the pipes are hidden underground, though it is sometimes preferable to have some of them exposed.

3. What are the implications regarding any toxic levels to the plants or animals in your garden using greywater?

Aquarista recommends the use of low or phosphate free washing powders to use in your laundry.  Avoid the use of fabric softeners, and sodium hypochlorite (JIK).

We never take water from dish washing machines, so the abrasive nature of the dish washing detergent is not of concern. All dishwashing water must go into the sewer.

4. Who provides the greywater pipe work?

Aquarista provides all the pipes required from

  • the point of where the greywater pipes lead out of the building,
  • to the hose and sprinkler in the garden.

Our system switches on automatically and pumps the water as soon as about 35 litres are accumulated.

5. How much does the greywater system cost?

Prices are subject to a quote, and a fully installed system varies between R11,000 and R14,000 depending on the characteristics of the building.


6.  If I have a Fynbos garden, should i use greywater?

Provided that you adhere to the rules of what to use in your house, greywater is good quality water for Fynbos.  However you could combine this with our unique rainwater harvesting and storage system, and use a combination of greywater and stored rainwater through our Grand Opus System.

7. Can I use my irrigation that I already have with my greywater system?

Aquartista will provide you with a drive pipe 25 mm in diameter piped around the edge of the garden and attach 20 mm garden hoses with hose fittings and Gardena sprinklers. We never pump greywater into pop-ups or Microjets. Even with advanced filtering the system will soon clog.. The Aquagrey pump provides enough flow to produce a six meter diameter spay from a Gardena sprinklers, spraying simultaneously.

8. Do I have to move a hose around all the time with my grey water system?

We supply one or multiple hoses and sprinklers, spread around the garden.  Our pump is strong enough to pump through 2 Gardena sprinklers simultaneously, covering up to 60 square metres of area of your garden at once.  Large gardens would require the hoses to be moved, but there is no need to move the hose and sprinkler more often than once every day.

9.  What size pump does the greywater system use?

Our standard system comes with a small but very robust pump with an open impeller. One size of pump chamber fits all applications, and will even take a small block of flats. For larger blocks of flats, we batch the flats into for example four flats per grey water system. If there is a possibility that more grey water will be delivered to the unit with which the small pump can cope, we quote for and supply a pump with a higher delivery and multiple hoses and sprinklers. In this way, there is never any chance of wasting the grey water via the overflow to the sewer.

10.  Can I mix the rain and the grey water?

Aquarista will gladly fix a trickle feed from a rainwater tank to introduce this water at a slow rate into the grey water system.

11.  Can I store the grey water in a larger tank?

The very first rule of grey water is that you may not store it.  We pump it immediately to water your garden. If greywater needed to be stored a water purification system must be added to clean the water.

12.  How long does the grey water system take to install?

The typical installation takes 2 days to install.

13.  Does the greywater give off an odour?

Grey water does produce a faint odour while irrigating but, but the odour disappears within seconds after irrigating. Our maintenance instructions, which take a few minutes a week, will ensure that your grey water system will be odourless.


14.  Is the greywater bad for the garden? What detergents should I use?

No, provided that our instructions are followed regarding detergent agents, greywater isn’t bad for your garden.  Most detergents contain by weight up to one third pure phosphates which will build up in the soil, and be toxic over say ten years of continuous use. So instead, one brand stands out, viz Ecosoft a washing powder (detergent) which is environmentally friendly (and free of phosphates) – making it safe for Fynbos. You may use soda ash, or washing soda that will do just as well to emulsify oils and fats in the laundry.
