STORM WATER (RAINWATER) MANAGEMENT
Storm water (rainwater) is water that comes from precipitation and ice/snow melt – it either soaks into exposed soil or remains on top of impervious surfaces, like pavement or rooftops. Stormwater will eventually evaporate off of a level surface, but most often it flows as runoff to another location.
Storm water (rainwater) runoff is any water running off a land surface before it reaches a natural water body. It occurs when the rate of precipitation is greater than it can infiltrate, or soak, into the soil. Runoff also occurs when the soil is saturated. Runoff remains on the surface and flows into streams, rivers, and eventually large bodies such as lakes or the ocean.
Movement of this storm water(rainwater) across the soil causes erosion. It can also carry and deposit untreated pollutants, such as sediment, nutrients and pesticides, into surface-water bodies.
Impervious surfaces such as driveways, sidewalks, parking lots and streets block rainfall and other precipitation from infiltrating naturally into the ground, leading to even more stormwater and potential pollutant runoff.
Most of the world water problems such as flooding, drought, water pollution, water shortage are all related to rainwater. Due to climate change and urbanization, water problems are increasing throughout the world in both developing and developed countries. By proper rainwater management, we can reduce the risk of such problems and enhance the resilience.
Storm water (Rainwater) management solutions are techniques used to reduce rainwater runoff from causing damages, flooding and dispersing pollutants. Stormwater management involves detaining, retaining, or providing a discharge point for rainwater to be reused or infiltrated into the groundwater
One of the solutions designed to manage storm water (rainwater) is Rainwater Harvesting. Rainwater Harvesting (RWH) offers a small-scale best management practice to reduce stormwater runoff and the problems associated with it. By harvesting the rainfall and storing it for later use or direct groundwater recharge, water is slowly released back into the soil and then moves into groundwater table, providing a steady supply of water to local streams and river.
Rainwater harvesting can be used to achieve a source control of rainwater, as it significantly reduces the peak flow and volume of rainwater runoff.
Collecting and Using rainwater strengthens the hydrological cycle, reduces storm water runoff and limit the demand for water from well, lakes, reservoirs and rivers. It’s a self-sufficient renewable water source that eliminates the need to rely on water treated with chemicals.

Maji ya mvua (Mvua ya mvua) ni maji ambayo hutoka kwa mvua na barafu au theluji kuyeyuka - ama huingia kwenye udongo ulio wazi au hubaki juu ya nyuso zisizoweza kupenya, kama vile barabara au paa. Hatimaye maji ya mvua ya mvua hutoweka kutoka kwenye uso ulio sawa, lakini mara nyingi hutiririka kama maji ya maji ya mto hadi mahali pengine. Maji ya mvua (maji ya mvua) ni maji yoyote yanayotiririka kutoka kwenye uso wa ardhi kabla ya kufikia mwili wa maji ya asili. Inatokea wakati kiwango cha mvua kinapokuwa kikubwa kuliko kile kinachoweza kupenya, au kunyunyizia, katika udongo. Mtiririko wa maji hutokea pia wakati udongo unapokuwa na maji mengi. Maji hayo hubaki kwenye uso wa bahari na kuingia katika vijito, mito, na hatimaye katika miili mikubwa kama vile maziwa au bahari. Mzunguko wa maji haya ya dhoruba (maji ya mvua) kwenye udongo husababisha mmomonyoko. Pia inaweza kubeba na kuweka uchafuzi usiotibiwa, kama vile sediment, virutubisho na dawa za kuua wadudu, katika miili ya maji ya uso. Maeneo yasiyo na maji kama vile barabara, vijia, maegesho na barabara huzuia mvua na mvua nyingine kutoka kuingizwa kwa asili kwenye ardhi, na kusababisha maji ya mvua zaidi na uchafuzi wa mazingira. Matatizo mengi ya maji duniani kama vile mafuriko, ukame, uchafuzi wa maji, upungufu wa maji yote yanahusiana na maji ya mvua. Kwa sababu ya mabadiliko ya hali ya hewa na mijini, matatizo ya maji yanaongezeka ulimwenguni kote katika nchi zinazoendelea na zilizoendelea. Kwa usimamizi sahihi wa maji ya mvua, tunaweza kupunguza hatari ya matatizo kama hayo na kuongeza upinzani. Usimamizi wa maji ya mvua ni mbinu zinazotumiwa kupunguza maji ya mvua kutoka kwa kusababisha uharibifu, mafuriko na kueneza uchafuzi. Usimamizi wa maji ya mvua ni pamoja na kuhifadhi, kuhifadhi, au kutoa hatua ya kutolewa kwa maji ya mvua ili kutumika tena au kuingizwa katika maji ya chini ya ardhi. Mvua ya mvua (RWH) ni mbinu ya kuokoa maji ya mvua na kupunguza matatizo yanayohusiana nayo. Kwa kukusanya mvua na kuhifadhi kwa ajili ya matumizi ya baadaye au moja kwa moja maji ya chini ya ardhi, maji ni polepole iliyotolewa nyuma katika udongo na kisha huelekea chini ya ardhi maji ya chini ya ardhi, kutoa usambazaji wa maji ya kudumu kwa vijito na mito ya ndani. Mvua ya mvua inaweza kutumika kwa ajili ya kupata chanzo cha maji ya mvua, kama ni kwa kiasi kikubwa hupunguza kilele mtiririko na kiasi cha maji ya mvua mtiririko. Kukusanya na kutumia maji ya mvua huimarisha mzunguko wa maji, hupunguza maji ya mvua na kupunguza mahitaji ya maji kutoka kwa visima, maziwa, mabwawa na mito. Ni chanzo cha maji cha kujitegemea kinachoweza kubadilishwa ambacho huondoa haja ya kutegemea maji yaliyotengenezwa kwa kemikali. Maeneo ya maji ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua ya mvua
