Two years later, Her Majesty's Inspectorate of Pollution took control of the works, and in 1996 new storage lagoons were built, to contain surface drainage water in times of flood.

The land reclamation works includes : removal of structures; removal of residual contamination; re-profiling of colliery spoil tips; removal of coal workings and mine entries; and provision of surface drainage.
33.
In general, hydrologic units were delineated such that all surface drainage within each unit converges at a single outlet point a type of hydrologic unit called a " classic hydrological unit ".
34.
As opposed to traditional hole punctured artificial playing surface drainage systems, custom rows are integrated to allow 40 % more drainage which is certified to drain 40.14 inches of water per hour.
35.
Take steps to eliminate ground moisture from the outside by checking to see if surface drainage around the house is adequate _ the ground should slope away from the foundation on all sides.
36.
Because of erosions, numerous cracks, caves and sinkholes which prevail in the limestone, two of the three lakes have no surface drainage : the water of the F�lensees flows by the mountain ridge southwest into the Rhine.
37.
If there is no surface drainage path, water from surface melting will flow downward and collect in crevices in the ice, while water from basal melting collects under the glacier; either source can form a subglacial lake.
38.
During spring snowmelt, outflow is sufficient for surface drainage to occur via a shallow channel across the lava flow, into Lesser Garibaldi Lake and Barrier Lake about 1.6 km ( 1 mi ) west of the main lake's shore.
39.
When cultivated, acid sulfate soils cannot be kept wet continuously because of climatic dry spells and shortages of irrigation water, surface drainage may help to remove the acidic and toxic chemicals ( formed in the dry spells ) during rainy periods.

This set of equations can be solved numerically at each runoff time step to determine how an inflow hydrograph to the LID unit is converted into some combination of runoff hydrograph, sub-surface storage, sub-surface drainage, and infiltration into the surrounding native soil.
