Rainwater Harvesting in Buildings

Öz

The amount of usable water in the world and in our country is decreasing day by day with the increasing pollution and excessive consumption pressure on water resources. The negative impact of global climate change on water resources, especially with the increasing population and industrial activities, is increasing day by day. For this reason, the use and saving of water is of great importance today, and efficient and conscious use of resources with new strategies is required. Alternative technologies for water resources such as reducing water consumption through industrial production with innovative technologies, treating and reusing domestic wastewater, obtaining fresh water from sea water in areas where water shortage is intense, and rainwater harvesting in buildings are becoming increasingly widespread all over the world. The use of rainwater harvested in the sustainable use of fresh water resources in many areas can create an alternative water resource. Rain water collected from building roofs is used for domestic needs or other needs such as garden irrigation, and its installation is quite simple compared to other technologies. In this study, the design principles of the systems used in the rainwater harvesting applications from the buildings were examined and compiled by conducting an extensive literature search, and the installation cost and depreciation period of rainwater harvesting systems were not included in the study. Recommendations for rainwater harvesting planning and implementation are presented.

BİNALARDA YAĞMUR SUYU HASADI

Öz

Dünyada ve ülkemizde kullanılabilir su miktarı, su kaynakları üzerinde artan kirlenme ve aşırı tüketim baskısıyla her geçen gün azalmaktadır. Özellikle artan nüfus ve sanayi faaliyetleriyle birlikte küresel iklim değişiminin su kaynakları üzerindeki olumsuz etkisi her geçen gün hızla artmaktadır. Bu nedenle günümüzde, suyun kullanımı ve tasarrufu önem kazanmakta olup kaynakların yeni stratejilerle verimli ve bilinçli kullanımı gerekmektedir. Yenilikçi teknolojilere sahip sanayi üretimi ile su tüketiminin azaltılması, evsel nitelikli atık suların arıtılarak tekrar kullanılması, su sıkıntısının yoğun olarak yaşandığı bölgelerde deniz suyundan tatlı su elde edilerek kullanılması ve binalarda yağmur suyu hasadı gibi su kaynaklarına yönelik alternatif teknolojiler tüm Dünya’da giderek yaygınlaşmaktadır. Tatlı su kaynaklarının sürdürülebilir kullanımında hasat edilen yağmur suyunun birçok alanda kullanımı alternatif su kaynağı oluşturabilir. Bina çatılarından toplanan yağmur suları, evsel ihtiyaçlarda veya bahçe sulama gibi diğer ihtiyaçlarda kullanılmakta olup diğer teknolojilere göre kurulumu oldukça basittir. Bu çalışmada, binalardan yağmur suyu hasadı uygulamalarında kullanılan sistemlerin projelendirme esasları geniş bir literatür araştırması yapılarak incelenmiş ve derlenmiş olup yağmur suyu hasat sistemlerinin kurulum maliyeti ile amortisman süresi çalışma kapsamına alınmamıştır. Yağmur suyu hasadı planlaması ve uygulanmasına yönelik öneriler sunulmuştur
