Lake & Pond Management

Westlake Golf Club, Cape Town, South Africa April - June 2017

Introduction

For golf course operators, proper ornamental pond and irrigation pond maintenance is an important aspect of grounds maintenance. Although ponds and lakes may not be as important to the golfer as the turf-grass, a pond that is not properly maintained can leave a negative impression. Customers expect a golf course to provide beautiful views and outstanding scenery. If ornamental ponds and irrigation lakes are less than their best, it can impair customer satisfaction.

The Problem

Westlake pond before

Westlake Golf Club 1000m3 ornamental pond problems:

  • Strong unpleasant odors
  • Green murky water due to the presence of green algae
  • Accumulation of 1m bottom sludge (muck).

The Golf Club operator had tried all available solutions on the market to remedy the problem. No solution could provide resolve the problem. Operator forced to empty the pond annually to remove this.

Recommended Solution

It is important to remember that ponds and lakes themselves are small ecosystems, and therefore, dissolved oxygen is key, as it helps encourage the growth of beneficial local bacteria. The smaller the pond, the easier it is to become eutrophic. Small ponds have an even greater need for aeration.

Most of common aerators on the market are inefficient and expensive and cannot distribute dissolve oxygen quickly and
evenly throughout the entire pond.

Based in the assessment of the site and water analysis data, our team of experts recommended 60 days treatment of the pond with MK1 Ultra Fine Bubble Generator to the Golf Club management.

The objectives of the treatment were to:

  • Remove the unpleasant odor asap
  • Remove the green algae and restore the water clarity
  • Reduce sludge layer at the bottom
  • Restore the natural balance of the pond
