RAINWATER HARVESTING & UTILISATION PROGRAMME AS-REWA Rainwater management is supported by the Czech legislation. While building their family houses, people are required by the building control authorities to provide for the rainwater liquidation on their construction sites. In any case, the rainwater management is an issue that should be treated not only comprehensively, but already in the preparation phase of design documents for the building warrant procedures. We can offer to you the most suitable solutions how to use and manage rainwater falling to the relevant building site. Such precipitations can be accumulated and consequently used in households, where they can replace, without any problems, drinking water for WC flushing, washing, etc. The rainwater is accumulated in underground tanks with subsequent overflows to stormwater infiltration facilities that replenish underground water reserves. The most simple, widely used and well known to everybody is the system of bringing rainwater from a roof gutter to a drum in a garden and its consequent utilisation for irrigation purposes. In principle, the AS-REWA system for the household use is practically the same philosophy, but its design and technical level is at a substantially higher and modern levels. D ASIO # The whole system for the utilisation of rainwater in households assumes: • to collect rainwater, • to clean it from mechanical impurities, • to accumulate it, and # ASIO # • to bring it to the relevant points of consumption. Q At the same time, it is necessary to provide for: • draining of excessive rainwater outside the system, and • possibilities of replenishment the system with drinking water (in cases of dry periods). washing machine other household consumption = 50% savings in drinking water consumption Water consumption distribution 32 % personal hygiene, bathing Drinking water replaceable with rainwater – total: 50% 30 % WC 8% petty hygiene, washing of hands "Rainwater“production: From 4% 8% 2% dishwashing general cooking & drinking cleaning purposes 12 % laundering 4% garden irrigation Effective roof area: P = a x b (m2) rainwater cleaned water AS-RAINMASTER – operating unit AS-REWA – tank

Trafficable (by walking) tank cover Excessive water overflow AS-REWA Kombi COMPACT UNIT The whole unit provides for: • rainwater filtration, • rainwater accumulation, • pumping of rainwater to the distribution system, and • replenishment with drinking water (in case of insufficient precipitations). The unit is supplied in standard accumulation volumes from 1 to 10 m3. Tank design: • plastic, self-supporting, • plastic, prepared for concrete encasement, • double-jacket for concrete pouring (PB - marking); the plastic materials are for isolation and concrete elements improve load-bearing...

AS-RAINMASTEROPTIMISED EQUIPMENT FOR RAINWATER UTILISATION IN FAMILY HOUSES AS-RAINMASTER is a fully automated operating and monitoring unit with a pump, control system and integrated replenishment with drinking water.. The equipment can be installed in a cellar, garage, or a groundfloor plantroom of any family house. Over the suction pipe, the water is sucked from the reservoir and then it is brought for garden irrigation purposes, flushing of toilets and filling of washing machines. If there is a lack of rainwater or grey water, AS-RAINMASTER will replenish the system automatically with...
