Before you drain your pool...

Sep 22, 2016

From the Village of Lindenhurst

In keeping with the Village of Lindenhurst, IL’s Storm Water Management Program Plan (SMPP) and meeting the requirements of the Municipal Separate Storm Sewer System (MS4), the Village would like to provide a friendly reminder from section 3.1.K Pool Dewatering from the SMPP.

Chlorinated water discharged to surface waters, roadways or storm sewers has an adverse impact on local storm water quality. High concentrations of chlorine are toxic to wildlife, fish and aquatic plants. The pH of the water should be between 6.5 and 8.5. Algaecides such as copper or silver can interrupt the normal algal and plant growth in receiving waters and should not be present when draining. Prepare appropriately before draining down a pool. It is recommended that one of the following measures be used:

1)      Dechlorinate the water in the pool prior to draining through mechanical or chemical means; these types of products are available at local stores.

2)      Dechlorinate the water in the pool through natural means. Pool water must sit at least 2 days with a reasonable amount of sun, after the addition of chlorine or bromine. It is recommended that the chlorine level be tested after 2 days to ensure that concentrations are at a safe level (below 0.1 -mg/l). Public Works can perform this test free of charge; to schedule a time, please contact the Village Office.

3)      Drain the pool slowly over a several day period across the lawn:

a)       Avoid discharging suspended particles (e.g. foreign objects blown into the pool like leaves, seedlings, twigs etc) with pool water.

b)    When draining your pool, do not discharge directly onto other private properties or into public right of way including storm sewer inlets.
