All construction affects groundwater and a water management plan will be required. From deforestation to urbanisation, from holes to heaps and dams to drains, they all have an affect on the groundwater. Deforestation causes an increase in the rate of run off of rainwater resulting in lower percolation of precipitation into the soil and a consequent increase in soil erosion leading to slope instability, hence land and mud slides. The increased rate of run off can cause small streams and large rivers to rise...
Fresh water is one of the planets most critical resources essential to all land based life It is also one of the planets most rapidly diminishing resources. Conservation and protection of existing supplies and the rehabilitation of degraded sources are one of the most urgent problems facing humanity today.
Many fresh water sources have been degraded to toxic levels by the inclusion of industrial, agricultural, and human waste products that have been discharged into the closest body of water, accidentally or deliberately for many years.
One of the greatest problems facing the planet is the management, conservation and equitable distribution of fresh water supplies. The fresh water sources may be lakes, rivers or ground water aquifers, most of which are now under stress.
