Management of landscape water in residential areas

Strict management of landscape water in residential areas is an important measure to protect water quality and maintain ecological environment. The following are some suggestions on landscape water management in residential areas.

It is forbidden to throw feed into the water.

It is forbidden to put feed into the water to prevent man-made deterioration of water quality.

Supplementary water source

Avoid using reclaimed water as much as possible for supplementary source water, because the water quality standard of reclaimed water is far from the national standard requirements of landscape water, mainly because ammonia nitrogen, total nitrogen and total phosphorus seriously exceed the standard, which further aggravates water pollution.

Control the number of fish

Fish breed very fast and have no natural enemies. Every year, the property should catch fish in time and control the number of fish not to exceed the standard.

There is no lawn.

It is strictly forbidden to put the cut grass into the water to feed the fish, so as to prevent the grass from rotting in the water, increase the organic matter content and cause serious pollution of the water body.

Use less pesticides and fertilizers.

Use pesticides and fertilizers as little as possible in the process of planting lawns and trees in coastal green space to avoid the pollution of the lake caused by rainwater flowing into the lake.

Direct irrigation of green space

The reclaimed water in the community should be directly used to irrigate the green space, instead of injecting reclaimed water into the lake and pumping water from the lake to irrigate the land. Because in this process, the high concentration of nitrogen and phosphate fertilizer in the water has diffused into the lake, causing eutrophication of the lake and cyanobacteria outbreak, which is harmful to everyone.
