For a household, this will be the piping network that supplies the building with the harvested water. The process comprises of four key steps.

It has been noted however, with the increasing costs of weld mesh, chicken mesh and galvanized wire, that in many places, ferrocement tanks now cost much more than alternatives built with bricks. Try again? It must be noted that where high volume storage is needed but where space is limited and aesthetic quality is an issue, cisterns may still be the best option as they are installed below the building footprint and therefore hidden. Smooth metal sheet catchments with a steep gradient have higher runoff coefficients than flat concrete catchment surfaces for example, which absorb a higher portion of. Direct roof capture off city buildings or capture of excess runoff from paved surfaces can be used to fill cisterns and other storage facilities that can be used for irrigation of green spaces and recreational facilities, washing and cleaning of streets and facilities, or for fire fighting.

    You will also need to regularly inspect the pipe to ensure no leaves or other materials have become lodged in the pipe and that the system is draining properly.

    Access to a safe and reliable source of water still remains a number one development priority in the Caribbean. Cover all openings to tanks with mosquito mesh to prevent insects, frogs, toads, snakes, small mammals or birds entering the tank.

    This Handbook is accompanied by a range of general and technical information products that have been developed with the assistance of UNEP and includes policy guidelines for RWH, educational posters, brochures, technical fact sheets, radio public service announcements, a television production, stormwater RWH management recommendations for aquifer recharge and computerassisted mapping to estimate rainwater harvesting potentials.

    In this case the availability of a virtually unlimited supply of water is now meeting the development needs for water on these islands, but it comes at a significant cost due to the energy inputs required. Caribbean Rainwater Harvesting Handbook designed for wastewater storage and other non-drinking purposes are not used, as the chemical constituents used in their manufacture can dramatically reduce the quality of the stored water.

    The second tank adds to the total storage volume of the system, so both tanks can be half the size of what would otherwise be required in the pressurized system.

    In addition, other animals need to be excluded from access to the water storage such as vermin rodents, other insectsfrogs and toads, as they too can transmit potentially harmful pathogens.

    The system draws water from the rainwater harvesting tank and stores it in a pressure tank until needed. In these instances, the stored water will drain away or has the potential to become contaminated by surrounding groundwater.

    There are a few simple maintenance procedures that are needed for first-flush diverters. RWH systems are best-suited where the roofing material is smooth and coated with chemically neutral substances.

    Plastic tanks Moulded plastic tanks have become popular in recent years as they are relatively light-weight, easily installed, water-tight and do not corrode. Augustine, Andrew P.

    Plastic tanks constructed from food-grade materials are becoming increasingly popular with improvements in durability, and they do not negatively impact water quality. The first flush diverter works by Figure 10 Simple first-flush diverter channelling the first flow down the downpipe to its base where it encounters a cap with a small drain hole the drain hole will allow for gradually drainage else, the system will need to be drained manually.

    To minimize the amount of leaf litter that gets on to the roof and trapped in the guttering, you should trim away overhanging branches.

    For buildings with multiple residential units, separate pressurized systems are recommended for each for ease of management and redundancy purposes. As a start it is best to try to draw out your roof plan with estimated measurements for each section that drains to guttering and then determine the sizes of each contributing area. A typical RWH system can be complemented by a host of other devices and measures to maintain and improve water quality.

    Typical applications will include washing and cleaning, cooling, fire fighting, bathing pool recharge and irrigation. Cost effectiveness will also depend on the fluctuations in wind and sunshine versus fluctuations in water demand.

    Figure 11 First-flush diverter diverters. If the roof is not a simple rectangle, then you will have to divide the area into sections, calculate each area and add them to estimate the total catchment area. Depending on the water requirements, more than one tank may be installed as part of the RWH system.

    Gutters should not have flat areas where debris can collect and water pool, as these may provide sites for mosquitoes to breed.

    2. Nabar:

      These filter systems are typically installed after the storage before the extraction point for use. This method is applicable in cases where sufficient rainfall and catchment area are available.

    3. Maukinos:

      Keep gutters clear. In this case the contributing roof area is simply calculated by multiplying the length of the roof by its width.

    4. Tera:

      This is a particularly useful consideration for RWH systems supplying water to facilities in remote locations. Lucia Water Week, May
