FREQUENTLY ASKED QUESTIONS

  • What is the difference between rainwater, stormwater, grey water, potable water, and others?keyboard_arrow_down

    Rainwater is fresh precipitation fresh from the sky that has not touched the ground surfaces. A roof surface maintains the rainwater quality.

    Stormwater is rainwater from a rainfall event that has touched the ground surface and unmanaged at the source. This water must be managed further down the flow path by stormwater systems.

    Groundwater is water present below the earth’s surface i.e. aquifers, wells, etc.

    Surface water is water present on the earth’s surface i.e. lakes, streams, rivers, etc.

    Potable water is water safe for human contact (showers), consumption, and food preparation

    Grey water is once used water discharged from washing machines, showers, bathtubs, bathroom sinks, etc. Grey water does not have fecal/urine contamination.

    Black water is once used water discharged from kitchen sinks and toilets and may contain fecal/urine contamination.

  • What is Rainwater Harvesting?keyboard_arrow_down

    Rainwater harvesting is the process of retaining, diverting, or processing rainwater for a number of uses. If planned correctly a rainwater harvesting system can supply almost every household use of water. A properly sized system can supply all your water needs.

    Rainwater storage systems that are developed to harvest rain through catchment, conveyance, and storage and can provide rainwater for daily water needs. Rainwater storage systems are increasingly being integrated in urban settings around the world to reduce water demand and demand on community infrastructure. Rain harvesting can be as simple as a rain barrel at the end of a downspout or as complex as a multiple-end-use underground storage system. Harvested rain can be used outdoors for irrigation; indoors for toilet flushing and laundry; and if filtered, as drinking water. The system scope, treatment method, and technologies will vary depending on end-use of the water.

  • Why do you harvest rainwater?keyboard_arrow_down

    The three main motivators for rainwater harvesting are:

    • Financial benefit through water savings.
    • Meeting stormwater management regulations.
    • Access to potable water.
    Key Reasons for Rainwater Harvesting

    An emerging movement to create more environmentally ethical and sustainable communities which are concerned with diminishing clean water sources are participating in the use, re-use, and recycling of water and energy resources. Rainwater harvesting can contribute to the overall goal of sustainable housing and community infrastructure. It can be part of a total package of sustainable home design, or a first-step toward participating in the green-lifestyle paradigm. As well, over time there can be a significant savings in cost of water and charges for stormwater.

    • Rainwater is a FREE source of water which is available to all from Mother Nature.
    • Rainwater is a renewable, sustainable, and a high quality source of water.
    • Rainwater is already soft, and has a neutral in pH.
    • Rain is free from disinfection by-products, salts, minerals, and other natural and man-made contaminants.
    • Rainwater harvesting can reduce water bills including city storm sewer charges.
    • You can avoid municipal watering schedules, or watering bans in dry climates.
    • It can alleviate demand on aging municipal water supplies. The average Canadian uses 329 litres of water a day. In the summer months, water consumption doubles with 50% of treated water being used to irrigate lawns.
    • Stormwater can be managed by catching it and reducing the amount of flooding to your foundation area
    • Rainwater harvesting is a strategy to actively improve the environment.
    • Seasonal rains can be stored to be used in times of drought and municipal water bans.
    • Rainwater harvesting systems reduce erosion, property flooding, and contamination by capturing the majority of urban runoff from a house.
    • Reusing water saves considerable amounts of energy. For example, 33% of the City of Toronto's electricity use in a year is spent on water pumping and treatment.
  • What are uses of rainwater harvesting?keyboard_arrow_down

    Cleanflo Rainwater Systems are designed to be used for three different levels:

    • Irrigation only
    • Toilets,laundry, and irrigation
    • Drinking potable water and human contact

    Any use that you are presently using water for, can be substituted with rainwater. Initially most people use it for landscape and garden irrigation, though it can easily be used for car washing, and other outdoor uses, as well as for toilet flushing.

  • Are there laws or guidelines which govern rainwater harvesting?keyboard_arrow_down

    Cleanflo Rainwater systems meet CSA standards for rainwater and stormwater re-use. Cleanflo systems are engineered and qualify to meet permit guidelines. Each municipality has its own guidelines. Cleanflo will ensure your project can be permitted and is successful.

    • A comprehensive rain harvesting system that is plumbed into a building requires expert advice for the design of the system and assistance with seeking regulatory permission.
    • When installing a rain harvesting system, ensure that there is suitable warning to ‘not cross connect rain harvesting lines with indoor potable lines’, and mark all pipes and faucets, both indoor and outdoor, as ‘non-potable supplies not suitable for drinking’.
    • Connect your cistern or rain barrel to another stormwater management system like a soakaway pit to receive and infiltrate excess water into the ground when the system is full.
  • How do I determine the potential volume of rainwater that can be collected from a roof?keyboard_arrow_down

    A single square metre multiplied by 1 millimetre of rain equals 1 litre of water, is the rule of thumb. Average rainwater tables can be found at Rainwater Harvesting Stats and Tables - Average Rainfall Table

    A simple calculation: Roof area in square meters X Rainfall in millimeters = Litres of rainwater

  • How do I determine the amount needed for my intended uses?keyboard_arrow_down

    Determining rainwater systems is based on three factors:

    • Catchment area (roof area) - for 200 m2 or less
    • Intended use and anticipated water needs
    • Possible rainfall amounts

    Based on the optimal volume of rainwater available to collect, the user must determine if the anticipated water needs will exceed available rainwater. If the user requires additional water, this can be achieved by topping up the rainwater with a municipal water supply, or by incorporating the capture and use of grey water sources.

    The Canadian Morgage and Housing Corporation has published guidelines for rainwater harvesting systems which include tables for estimating the optimum rainwater cistern. These tables have been reproduced at Rainwater Harvesting Stats and Tables - Optimum Rainwater Cistern Tables cloudRain Harvesting Calculator

  • What is the best tank size for my system?keyboard_arrow_down

    You need to store enough water to last between major rain events. This can be determined by calculating the historical averages and your catchment surface. It will also depend on the amount of rainwater you wish to use from the system. For example, watering patio pots versus watering a garden will require a different amount of water storage. It will also depend on whether you intend to store water beyond the rainfall season in an underground tank. There are many variables that will help determine the ‘best’ tank size.

  • What maintenance is involved when you install a rainwater harvesting system?keyboard_arrow_down

    The rainwater harvesting system maintenance will depend on the system components that are used. See the product recommendations to get information about maintenance of your rainwater harvesting system. Cleaning the roof, eaves troughs, filters, and monitoring water quality are ongoing requirements for all rainwater systems. If greywater is being recycled, further inspections will be needed.

  • How will freezing impact the harvest and use of rainwater?keyboard_arrow_down

    Seasonal rainwater systems need to be decommissioned for the winter months if your home is subject to freezing winter conditions. Users that require year-round access to their collected rainwater will need to store their water tanks indoors, in a heated location, or buried below the frost line.
